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.
