                          CALIFORNIA CODE OF REGULATIONS


         Technologies, Ltd. of P. 0. Box 25324 Albuquerque NM $7125, has

applied for exemption from the prohibitions of Section 27156 of the

California Vehicle Code for their Platinum Vapor Injector (PVI) device.        The

device is designed for installation on 1989 and older model—year diesel—

powered vehicles.

         The applicant submitted a sample, drawings and specifications of the

device for our inspection and evaluation.


         Based on the following:   (1) previous testing of the device by the

Air Resources Board (ARB) on a gasoline powered vehicle; (2) the emissions

test results on a diesel engine conducted by Detroit Diesel Corporation; (3)

the smoke opacity test results conducted by Southern California Rapid

Transit District (RTD) ; (4) staff‘s engineering evaluation of the device;

and (5) the previous exemption of devices that operate in a manner similar

to PVI, the staff believes that PVI will not have any effects on exhaust

emissions or fuel economy.

         The staff recommends that Technologies, Ltd. be granted an exemption

from the prohibitions in California Vehicle Code Section 27156 for their

PVI device and that Executive Order ({E.0.) D—189 be issued.


       The PVI device is a vapor injection system.          It consists of a plastic

case, a 12 or 24 volt electrical hook—up and a platinum vapor supply hose.

The case dimensions are:      6—1/4" width; 2—5/8 depth; and 8" height.       The

case contains a reservoir with ethylene glycol solution, a small vacuum

pump, and tubings which connect the reservoir to the vacuum pump.           The

vacuum pump is to compensate for the lack of vacuum in a diesel engine at

low rpm.

       The reservoir is made of molded plastic .           There are two outlet

nipples with a 0.015 orifice on the upper part of the reservoir both of

which are connected to the vacuum pump.           A 5/8" fill tube with a screw cap

is made an integral part of the reservoir.          A 1/16" hole is to be drilled in

the middle of the cap, during installation of the device, as the only

opening to the atmosphere.          The bottom of the tube is connected to the

reservoir.   A fill line is marked on the side of the reservoir to indicate

the limit of the reservoir‘s filling capacity to approximately one—half of

its volume (nominal fill is approximately one pint).           The proprietary

platinum solution is to be added to the reservoir when the installation is

complete.    See appendix A for installation instructions and Appendix B for

PVI drawings.

       In operation, negative pressure from the vacuum pump at low rpm and

the engine intake manifold at high rpm is applied to the upper portion of

the reservoir through the connecting tubings.          This allows air from the

atmqsphere to enter through the fill tube into the bottom portion of the

reservoir.   The air then bubbles through the fluid and rises to the upper

portion of the reservoir to be mixed there with the liquid vapor.      This

mixture is then drawn into the engine‘s intake manifold via the air intake

hose between the air filter and the intake manifold.

v.       Y             ION
       Evaluation of the PVI device is based on the following:

             A.   The ARB‘s comparative emission tests on a 1980 model—year

Chevrolet Monte Carlo with a 305 CID gasoline powered engine.     The results

does not show any effects on exhaust emissions or fuel economy.      See

Appendix C for the ARB‘s comparative emissions test results.

             B.   Detroit Diesel Corporation‘s back—to—back tests on a 1988

model—year diesel engine using federal transient emission test cycle.         The

results shows that the device has negligible effects on the exhaust

emissions.   The comparative test results are shown in Appendix D.

             C.   The RTD‘s comparative smoke tests on diesel buses to

determine the effects of the PVI on exhaust smoke opacity.     The results

indicate that the PVI has no effect on exhaust smoke from diesel buses.

Appendix E shows the RTD test results.

             D.   Staff‘s engineering evaluation of the device indicate that

the PVI does not have any effects on exhaust emissions or fuel economy.

             E.   The previous evaluation of devices that operate similar to

PVI showed that vapor injector devices that meet ARB‘s requirement of

orifice size would not have any adverse effects on the exhaust emissions.

       Technologies, Ltd. claims that; (1) the platinum solution aids in a

faster and more complete combustion of the fuel by catalytic split of

molecular 0, to radical 0; (2) reduction of smoke up to 60%; (3) reduction

in CO emissions; and (4) additional engine life time.   However, the company

does not offer any scientific explanation to substantiate these claims.

The comparative emission test results that were used for evaluation of the

device did not show any effects on the exhaust emissions.

       In the past the ARB has evaluated several vapor injectors that

operate similar to PVI.   During these evaluations, it was found that the

air—bleed orifice size of the device determines whether the device would

adversely affect vehicular emissions.   The PVI‘s orifice (0.015) is below

the maximum allowable limit.   Since qualifying for an exemption from

prohibitions of Vehicle Code Section 27156 is based on not adversely

effecting»exhaust emissions, the staff recommends that Technologies, Ltd. be

granted an exemption as requested.

                                                                    APPENDIX A

                  Installation of Dispenser/Pump Container Case
   a.     The back of the case has 1/4"         holes for bolt and nut or sheet
          metal  attachment.    Attach to the most       convenient  and
          gdyantageous position closest to the air intake and electrical
          injector pump terminal.   The back of the case also has 3/8"
          slots at the top and bottom to accommodate nylon ratchet
          straps for securing the device in some installations.

   b. _   DO NOT INSTALL THE PLATINUM VAPOR                INJECTOR   (PVI)       NEAR   OR

   c.     A few minutes of thought and diagnosis on the first installa—
          tion is necessary.   No definite instructions for placement
          can be given as there are many variations on the same engines
          or because of various under—the—hood accessories.


   The 12 (or 24) volt positive electrical supply to the vacuum pump
   has to be connected to the injector pump terminal. (RED WIRE IS
   POSITIVE.)  Carefully check your intended connection, so that the
   power goes on and off with the ignition key.    This is a MUST as
   power is to be supplied only while the engine is operating.                     Ground
   the black wire.


   The 3/16" platinum vapor supply hose is attached to the closest
   point, nearest to the engine of the intake air duct or to the
   intake side of the turbine (duct before turbine). The rubber air
   duct on large diesel engines can be drilled with a 1/4" drill
   very carefully three—fourths of its depth and then punctured with
   a sharp pointed awl.   The 3/16" x 1/4" plastic fitting is then
   inserted into this hole (the 45—degree angle is to be positioned
   opposite      airstream flow).     Insert the     45—degree —      1/4"    end first
   and    then    apply   rubber   silicone    to   seal    and   retain     in    proper

position.           The   3/16"       end    is   then      connected,    with     rubber    hose
supplied, to the pump at the container case with the 3/16" x 3/16"

On small diesel engines, the center of the air cleaner lid is
drilled with a 3/8" bit to accommodate the 90—degree nylon elbow
with the 3/16" nozzle.   NEVER                    INSTALL ANY PLATINUM VAPOR SUPPLY

On some engines, such as VW diesel Rabbits, the crankcase breather
hose, nearest the air cleaner box, is the best place for entry.
A 90—degree nylon elbow is inserted into a 3/8" hole at the top
of the breather hose and rubber silicone is applied to retain in
proper position.  The 3/16" end is then connected with rubber hose
to 3/16" pump hose.                      '

The above explanation serves as an example to explain the simplicity
of   the    installation        of     the    Platinum Vapor           Injector    (PVI).     All
installations are relatively                      easy,       requiring    little     time    and
adaption procedures.


The bubble flow on any engine at idle should be 30 to 35 bubbles
every 10     seconds.       The bubble flow rate is                 observed at the         sight
window      (Fig.    I or II).              At approximately 1500 RPM,              the bubble
flow rate should be about double.     Bubble flow is the same for
all engines, as only the concentration of the platinum is increased
to supply the requirements of larger engines consuming more fuel.

If the flow of bubbles needs to be requlated, it is done as follows:
The rubber seal plug on the pump is removed. Inside is a potenti—
ometer control with slots. A plastic screwdriver is supplied for
this adjustment.   Use plastic screwdriver only.   pO NOT USE A
METAL      _SCREWDRIVER     —     electrical          short    could    occur   and   the    pump
would be      ruined.           The    potentiometer           is   adjusted      clockwise    to
increase bubble flow — counterclockwise to decrease. Adjust while
engine is idling at the previous instruction rate of 30 to 35
bubbles every ten (10) seconds.    A faster rate of bubbles only
wastes platinunm.

The Platinum Vapor Injector                    (PVI)     is now operational and ready
for the platinum solution.   Do this while the engine is running.
Remove black cap on vertical tube and pour in the number of 1 oz.
platinum concentrate vials as follows:

       One vial for engines getting over 10 miles per gallon.
       Two vials for engines getting 5 to 10 miles per gallon.
     _ Three vials for engines getting below 5 miles per gallon.

Drill 1i/16"        hole in middle of cap — remove inner cap seal and
replace cap.         The hole in the cap is needed for vacuum and bubble
flow.      Mark the mileage and date of installation in obvious place.
Also keep data in glove compartment.    This is for reference to
replenish the platinum approximately every 6,000 miles or 200
hours for hourly usage on stationary units.

Air Duct Brass Fitting Installation
(Alternative Method Into Metal Duct)

It may be more desirable to make the installation into the metal
duct of the air supply.   A Weatherhead #1541 is the ideal brass
fitting to do this.     The metal    duct will   need to be drilled and
tapped to receive this threaded fitting.          The end that goes into
the air duct will need an extension of 1 to 1 1/2 inch copper
tubing that is silver—soldered into place.   The end of the copper
tube should be ground to a 45—degree angle to acquire the most
venturi effect.   Be certain that the 45—degree angle is opposite
the airstream flow. Mark outside hex on fitting to verify position,
or use Weatherhead marking.     This is the most ideal way but is time—
consuming, and care must be taken not to allow grindings into the
air intake.    This will necessitate removing the rubber duct
connectors and carefully cleaning all internal areas before
assembling again. This fitting will be supplied at your request.
Ask for W.A.D. fitting.

                               CAUTION LIST

 1.   Do not install near or on anything hot.

 2.   Attach firmly to resist engine and road vibrations.

 3.     Attach (if possible} so the pump potentiometer is
      _ accessible and visible. ~

 4.   Connect red positive wire to injector pump terminal.

 5.   Make proper and complete electrical connections.

 6.   Hose connections should not leak — attach firmly.

 7.   Use only plastic screwdriver if you need to adjust
      potentiometer for bubble flow.

 8.   Never flow the platinum vapors through the air filter.

 9.   Drill 1/16" hole in vertical tube black cap and remove
      inner seal.

10.   Check all other previous instructions.

       The purpose of the meeting was to discuss the operating
       principles   and  installation    requirements   for    the
       Platinum   Vapor Injector   (PVI)   on  District     buses.
       Technologies Ltd.‘s  representatives stated    that    they
       expect   a   50—90%   reduction       in    smoke      opacity    with     the
       installation of the PVI on the Detroit Diesel 6Vv92  TAC
       engine, which powers the majority of the District‘s bus

       Mr.   Farland,   Chairman of      the Board of T.L.,               requested
       that the District       supply two         (2)   buses on which           T.L.
       would install  the PVI   system for   test purposes.   BHe
       further requested that these buses exhibit higher    than
       normal smoke opacity   levels.  Based   on this  request,
       the following test plan was outlined and agreed upon by
       T.L. and District personnel.

       1.    District staff will select two (2) buses that
             have higher than normal smoke levels.

       2.    District personnel will then perform a loaded mode
             smoke opacity  test  in  order  to  determine  the
             baseline smoke opacity levels of the buses.

       3.    T.L.‘s   representatives will  then  install    and
             calibrate the PVI system on the baseline buses.

       4.    District  personnel  will  then  retest  the                         PVI
             equipped buses to determine PVI‘s effect on                        smoke
             opacity levels.


       The initial smoke test plan called for two buses to  be
       tested on the chassis   dynamometer at  Division  3303.
       These buses,     8877 and   7661, were   selected for                    their
       higher  then     normal   smoke  opacity   levels  and                    were
       baseline tested       in an    "as    is" condition,          no     engine
       tune—ups were   performed.           Baseline testing            began      on
       August 1, 1988.

       Following the baseline smoke          test on bus        8877 and        7661,
       T.L.‘s representatives        installed          the    PVI   system        on
       these buses; smoke opacity tests were then performed in
       the PVI  equipped  condition.   Following  these  tests
       T.L.‘s representatives requested that the buses be

       placed in revenue  service               to  accumulate mileage   with
       the PVI system  operating.                At this  time, they   stated
       that the PVI system would need to operate 2500 imiles in
       order to exhibit        reductions in              smoke opacity    levels.
       The District agreed           to T.L.‘s request          and placed           the
       the  buses  in  normal  service.   After   the   mileage
       accumulation, the buses  were tested again   in the  PVI
       equipped condition  on August  26  and 31,   1988.  (See
       attached test results.)

       On  August  4,  1988,  T.L.  requested  that   two   (2)
       additional buses be tested  for baseline smoke   opacity
       levels then PVI equipped by                T.L.    and placed in     normal
       revenue service        to     accumulate milage.           The     District
       also agreed to      this request and               bus numbers 7669           and
       7658 received baseline smoke opacity test on August  5,
       1988.  These buses were  equipped with the PVI  systems
       by  T.L.   and  placed  in   normal  revenue   service.
       On   September    14        and   15,.     1988,     following      mileage
       accumulation,    the buses were tested               in the PVI    equipped
       condition.                                                               '


       The smoke  test  procedure  used   is   similar  to  that
       outlined  in  SAE,  J—35,  "Diesel    Smoke   Measurement
       Procedure," with the addition  of a stall torque    mode.
       The tests are run with the bus positioned on a    chassis

       The smoke test procedure             employed consists of           running
       three   consecutive    smoke    cycles.       Throttle    position
       during the   cycle    is   either      fully   closed    or   fully
       opened.     Following      the    instrumentation           set—up,
       smokemeter calibration, and a          10 minute maximum      power
       warm—up, the   first smoke      cycle is      begun.    The   first
       cycle starts with     a 20   second idle       period; then      the
       transmission is    then put     into drive      and the     bus   is
       accelerated     (1st   acceleration}       at     approximately    1
       mile—per—hour,    per    second,    {(1.  mph/sec)     while     the
       transmission is    allowed     to up—shift      into    high    gear
       bringing the   engine     to   rated speed       (2100   rpm)    and

       The maximum  power mode  is held   for approximately  20
       seconds.  With the throttle still held fully open,   the
       engine is loaded down such that the rpm drops gradually
       to. intermediate  speed   (lug down).    The  engine  is
       brought back to  idle, the service   brakes are  applied
       and the engine is accelerated (2nd acceleration} to

        converter stall  torque for   approximately 10  seconds.
        At this point, the engine   is returned to idle and  the
        smoke    cycle       is   complete.             Three   smoke       . test       sequence
        cycles must  be run            back—to—back  before the  test  is
        considered complete.            Results from the smoke tests  are
        given in terms            of smoke opacity              and are divided              into
        five factors:

        "A"      factor represents acceleration                      smoke.

        "B"      factor represents          lug down smoke              (hill     climb).

        "C"_    factor represents peak smoke (puffs during early
                portions of rapid opening of the throttle}.

        "D"      factor represents          the    full       load,    rated      speed     smoke
                characteristics of              the engine.

        "E"      factor represents the full load intermediate speed
                smoke characteristics of the engine.

        The smoke        test chart         results are           validated and              read
        according  to   a procedure   adapted  from  SAE   J—35.
.       Essentially, the acceleration and lug portions of    each
{       cycle are  divided into   1. second intervals.   The   10
        highest   smoke   opacity    readings   from   the   two
        accelerations of each cycle are recorded.  The  average
        of these 30 smoke opacity readings yield the "A" factor
        or acceleration smoke factor.    Simillarly, the five   ©(5)
        highest readings  from the   lug  down portion    of  each
        cycle are determined.   The average of     these 15   smoke
        opacity readings yield                  the "B" factor              or lug       factor.
        The    "C"   factor   or    peak        smoke    factor,       is    determined        by
        taking the two highest of  the 10 values selected  from
        the acceleration portions of  each cycle.  The  average
        of these       six    smoke        opacity readings                 yield     the     "C"
        factor.  The   "D" and  "E"  factors are  determined  by
        locating the last 10 seconds   of the maximum power   and
        lug down modes.   The average smoke readings during this
        period yield the            "D" factor or             full     load rated           speed
        smoke and      "E"    factor or full              load    intermediate              speed
        smoke respectfully.                Of    these five            factors,       the     "B"
        factor or lug down and  the "E" factor or  intermediate
        speed are perhaps the  most repeatable followed by  the
    — acceleration or              "A" factor           and     the full          load      rated
        speed or  "D"   factor.  The                     peak     or        "C"     factor     is
        substantially more variable.                                                 '

           the raw  exhaust   plume  as it   issued  from   a  6—inch
           diameter  exhaust   pipe.    This   type  of    smokemeter
           measures the percent of   light extinction by the     total
           exhaust plume  from   the engine.    The   smokemeter   was
          connected to a    compatible strip—chart to   continuously
          record the smoke opacity during each cycle.      This meter
          has an accuracy of>   + 1 digit and   zero stability of    1
            percent.     Such   instrumentation       must     be   used    since        the,
            human eye detects      smoke opacity only near or above 4—5%
            level.                                           .

            Engine     performance      and     operating       conditions           were
           recorded during each test and they included:

                   Road horsepower
         0 0 0 o

                   Charge air pressure
                   Air inlet restriction
                   Engine rev/min.

           The results    of this    data indicates          that road horsepower
          levels were relatively consistent (within 5 percent  of
          baseline) and engine operating conditions were repeated
          from test to test.  Air inlet restriction was kept well
          below engine manufacturers‘ recommended limits and were
          relatively consistent from test to test.

          Modal engine RPM was held to + 50 rpm variance    between
          tests.   Acceleration  and   deceleration  —rates    were
          controlled as consistently as possible with the    manual
          dynamometer controls.


          The attached  tables present   the results   for all  the
          smoke tests performed on the   buses in this test.    All
          the  results,  whether    slight  increases   or   slight
          decreases in  smoke  levels compared   to   baseline  are
          within    experimental      test     variability      and
          instrumentation accuracy.   Thus, the PVI system has   no
          measurable effect on exhaust smoke opacity.

          Bus 8877 received a California Highway Patrol      citation
          for excessive   smoke  (CVC—27153)  while   operating    in
          revenue service with the   PVI system.   (See    attachment
          I.)  Bus 7661 was smoke tested after the removal of the
          PVI  system   and  the  engine  was  tuned    to    factory
           specifications.        The     "post     tune—up"         test       showed     a

 The   California        Air      Resourses     Board     has     supplied      the
 following statement:

       The California  Air Resources  Board (CARB)  staff
       has reviewed the Smoke Test Procedures used by the
       SCRTD and     has found        them to     be among       the    best
       currently in use.           The CARB staff belives that the
       SCRTD test procedures           are more     than adequate         to
       assess the impact of the           PVI device on the            smoke
       emissions from the transit  buses under test.   In
       addition the CARB staff observed much of the SCRTD
       testing  and  found   that  the   District‘s  test
       procedures were ridgedly applied.
