                  EVALUATION OF TURBODYNE SYSTEMS, INC.‘S BUSPAC
              FOR AN EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE
         SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                           CALIFORNIA CODE OF REGULATIONS


I.     INTRODUCTION

           Turbodyne Systems, Inc. of 6155 Carpinteria Avenue, Carpinteria, CA

93013 has applied for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code (VC)           for their BusPac electric supercharger

designed for the following Detroit Diesel heavy—duty engine family group

applications:        6V92TA,    1980—87, excluding engine families GGMOSS2FZGT7,

gGMOSSZFZG6,    HDDOSS52FZG1l;     & 6L7I1TA,   1988—90.   The exclusions from the engine

family group 6V92TA are due to the introduction of electronically controlled

fuel injection.

II.    CONCLUSIONS

           Based on comparative emissions testing performed with and without

the BusPac installed,          the staff concludes that Turbodyne Systems,     Inc.‘s

BusPac will not adversely affect exhaust emissions from the vehicles for which

the exemption is requested.

III.    RECOMMENDATION

           The staff recommends that Turbodyne Systems, Inc. be granfied an

exemption for their BusPac for installation on those applicable Detroit Diesel

heavy—duty engine family group applications:               GV92TA, 1980—87, excluding

engine families GGMOS52FZG7, HGMOSS2FZGE6, HDDOSS2ZFZG1l; & 6L71TA,           1988—90.   The

staff also recommends that Executive Order D—430 be issued.

IV.     BUSPAC DESCRIPTION

           The BusPac is an electric supercharger that can be installed on

almost any vehicle.        The kit operates in conjunction with the original

equipment manufacturer‘s (OEBM) mechanical fuel injection system and emission

control system already certified with the stock engine.

            The purpose of supercharging an engine is to increase its volumetric

efficiency and power output at particular engine loads and throttle openings.

With a conventional turbocharged engine, boost is minimal at low engine speed.

The BusPac is designed to supply boost at low engine speed in order to

optimize the air fuel ratio as the vehicle begins to move.               In diesel

vehicles, high particulate and hydrocarbon emissions occur at this time.                 At

heavy engine loads and increased throttle openings, the manifold pressure is

increased by the stock turbocharger allowing more air and fuel to enter the


engine,    resulting in a higher power output,        but there is a lag.     With the

BusPac,    as soon as the engine speed is brought above idle,          the BusPac is

activated,    supplying boost to the engine (3 to 6 psi).          When the stock

turbocharger begins to reach normal boost levels            (8 psi),   the increased

manifold air pressure is sensed by the BusPac intake plenum pressure switch

and the BusPac is deactivated.        At this time, the vehicle has accelerated into

motion,    and the engine and stock turbocharger are beginning to operate at

normal speed.     The BusPac is driven utilizing an electric motor and can be

shut off at anytime by turning off the master control switch.

             The BusPac uses a centrifugal type blower, designed to produce a

maximum boost of 6 psi        (3—6 psi typical).     The installation of the kit does

not require any major modifications to the stock Detroit Diesel engine,                except

for the insertion of the check valve and wye connection to the air intake

piping.>    The intake plenum pressure switch is installed between the stock

turbocharger and the engine intake manifold.            The throttle switch is mounted

to the governor.         All other BusPac connections are electrical.



v.           DISCUSSION_OF THE BUSPAC

             A 1985 model—year federally—certified Detroit Diesel 6V92ZTA

mechanical fuel injected engine was used for the evaluation of the Buspac.

The engine was tested on an engine dynamometer at the Southwest Research

Institute.     Testing consisted of two EPA Heavy—Duty Transient Emission Test

Cycle in the baseline and modified configqgurations.           The ARB did not perform

testing to confirm the test results submitted by the applicant.

             Results from comparative testing conducted at the Southwest Research

Institute between the stock and modified confiqguration yielded decreases in

hydrocarbons     (HC),    carbon monoxide   (CO),   & particulate matter   (PM),   and a

small increase in oxides of nitrogen (NOx)}.           The increase in NOx was within

the permitted 10% of baseline.         The weighted test results in grams per brake—

horsepower—hour were as follows:


                                    HC        Co        NOx       PM

  Baseline (cold)                0. 582     1.339    9 .241    0.175
  BusPac   {cold}                0. 446     1.141    9 .697    0.171

  Baseline (hot)                 0. 640     1.676    9 .932    0 .196
  BusPac   (hot)                 0 .525     1.186   10.323     0 .162

  Baseline    (weighted)         0 .621     1.579    9 .560    0 .192
  BusPac      (weighted)         0.514      1.18    10 .156    0.164

          % change weighted       ~17        —25      +6        —15
          % of baseline limit     +10        +15     +10        +15

            Although Turbodyne conducted testing on a federally—certified

engine,    the results from installing the BusPac are expected to be similar for

California certified engines since the technology of the engines for

California and federal are similar:          throttle delay,    after cooler, mechanical

fuel injection, direct injection,         and turbocharger.     Since none of the

controls are electronic and could not adapt to the presence of the BusPac,

test results performed with California—certified engines are expected to yield

very similar results.      Therefore,     based on the test results,    the staff

concludes that the installation of the BusPac will not have an adverse effect

on exhaust emissions on California—certified engines.

            Turbodyne Systems,   Inc.     has submitted all the required information

and fulfilled the requirements for an exemption.
