SUMMARY _asiize. Turbodyne Systems, Inc. of 6155 Carpinteria Avenue, Carpinteria, California 93013, has applied for an exemption from the prohibitions in Ssection 27156 of the California Vehicle Code (VC) for their Turbopac 2500 (electric supercharger) desiqgned for heavy—duty diesel vehicles equipped with mechanical fuel injection and no electronic injection timing or electronic throttle delay. Based on emissions test results, the staff concludes that the Turbopac 2500 will not adversely affect exhaust emissions from vehicles for which the exemption is requested. The staff recommends that Turbodyne Systems, Inc. be granted an exemption as requested and that Executive Order D—430—1 be issued.

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.
