             EVALUATION OF THE TURBODYNE SYSTEMS, INC., TURBOPAC 2500
               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,

California     93013, has applied for an exemptiofi from the prohibitions in

Section 27156 of the California Vehicle Code (VC)         for their Turbopac 2500

(electric supercharger) designed for heavy—duty diesel vehicles equipped with

mechanical fuel injection and no electronic injection timing or electronic

throttle delay.

II.    CONCLUSIONS

            Based on comparative emissions testing performed with and without

the Turbopac 2500 installed, the staff concludes that Turbodyne Systems,

Inc.‘s Turbopac 2500 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 granted an

exemption for their Turbopac 2500 for installation on those heavy—duty diesel

vehicles equipped with mechanical fuel injection and no electronic injection

timing or electronic throttle delay.          The staff also recommends that Executive

Order D—430—1 be issued.

IV.     TURBOPAC 2500 DESCRIPTION

             The Turbopac 2500 system consists of an electric supercharger

(Turbopac 2500),      check valve, wye connection,    flex hose,   hose clamps,   intake

plenum pressure switch, throttle switch (mechanical or pneumatic}, master

switch,   and Turbopac controller.      The system operates in conjunction with the

original equipment manufacturer‘s        (OEM) mechanical fuel injection system and

emission control system already certified with the stock engine.

             The purpose of installing the Turbopac on 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 and cruise conditions.          The boost levels in a stock


turbocharger system often lag behind actual demand by the driver.           The

Turbopac 2500 is designed to supply instantaneous boost (relative to stock

turbochargers)    during transient driving conditions beginning at low engine

speed and/or boost levels in order to optimize the power output until the

stock turbocharger reaches normal boost levels.        At 8 psi of boost,    the

Turbopac shuts off and the stock turbocharger continues to produce boost as

normal.

            In diesel vehicles,   high particulate and hydrocarbon emissions occur

at transitional periods from low boost levels to high boost levels          (low to

high ehgine load)}.    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 Turbopac 2500,    as soon as the engine speed/load is increased,

the Turbopac 2500     is activated,   supplying boost to the engine.   The available

boost increases the available power during the initial moments of transient

driving conditions.     When the stock turbocharger begins to reach normal boost

levels (8 psi and above), the increased manifold air pressure is sensed by the

Turbopac 2500 intake plenum pressure switch and the Turbopac is deactivated.

By this time,    the engine and stock turbocharger are operating at normal speed

and efficiency.     The Turbopac is driven utilizing an electric motor and can be

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

            The ihstallation of the Turbopac 2500 does not ‘require any major

modifications to the stock 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,    or when necessary,

a pneumatic throttle switch is utilized.        All other Turbopac connections are

electrical.


    v.        PISCUSSION_OF THE TURBOPAC 2500

              Because of the universal nature of this exemption,          four heavy—duty

    vehicles were tested for the evaluation of the Turbopac 2500.             The four

    vehicles tested were selected based on representativeness of the in—use fleet.

    The four test vehicles were equipped with the following engines:




    Make                      Model—Year      Engine Family      Engine Family Group

    Caterpillar                  1987         HCTO63SFPAS              3306
    Cummins                      1990         LCEO61L11FABX            L1O
    Detroit Diesel    (GM)       1984         EGMO42 6WFS              6L7I1TA
    Navistar                     1988         JNVO466FPA8              DTA466


    The vehicles were tested on a chassis dynamometer at the facility of

    California Truck Testing Services.       Testing consisted of two EPA Heavy—Duty

    Urban Dynamometer Driving Schedules in the baseline and modified

    configurations.     For each configuration, variation between tests was monitored

    by the ARB,   in the case of unacceptably high variation between tests,          a third

    test would have to be performed,       and the results averaged.     For the four
&




    vehicles, only one variation of 18% occurred for NMHC for one vehicle.               The

    remaining pertinent test results remained near or below 10% variability within

    each confiquration,      so only two tests per configuration were required for all

    four vehicles.      The ARB did not perform testing to confirm the test results

    submitted by the applicant.

              Results from comparative testing conducted at California Truck

    Testing Services between the stock and modified confiqurations for all four

    vehicles yielded average decreases in nonmethane hydrocarbons (NMHC),                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 test results in grams per mile were as follows:


                            NMHC      CO       NOx
 Caterpillar
               Baseline     0.250    4 .508   11.827
               Modified     0.266    2 .982   12.123
               % Change       +7       —~35     +3

 Cummins
               Baseline     0.861    9.973    13.397
               Modified     0 .851   8 .068   13.732
               % Change        —1      —19      +3

 Detroit Diesel (GM)
               Bagseline    0 .542   7 .662   12.014
               Modified     0 .405   4 .035   12 .767
               % Change       —25      —47       +6

 Navistar
               Baseline     0. 318   3. 330    8 .341
               Modified     0 .332   2.911     8.525
               % Change        +4     —13       +2

    % of Baseline Limit      +10      +15      +10


           Therefore,   based on the test results,      the staff concludes that the,

installation of the Turbopac 2500 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.
