Lostace, SUMMARY Gale Banks Engineering (Banks) has requested an update to Executive Order D—161—18, which exempts their Turbocharger System Model 6.2G from the prohibitions in Vehicle Code Section 27156, to include the 1992 model year Chevrolet/GMC vehicles powered by a 6.2L heavy—duty diesel engine. The 1992 model year 6.2L Chevrolet/GMC heavy—duty diesel engine is carried over from the previous year for which an exemption has been granted. In addition, smoke opacity tests conducted at Gale Banks shows that the add—, on turbocharger system will have no adverse effect on exhaust emissions from the engine for which the exemption update is requested. The staff recommends that Banks be granted an update as requested and that Executive Order D—161—26 be issued. 2s

EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARQER SYSTEM MODEL 6.2G FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION Gale Banks Engineering (Banks) of 546 Duggan Avenue, Azusa, California 91702, has requested an update to Executi&e Order (E.0.) Db—161—18 to include the 1992 model year Chevrolet/GMC vehicles powered by a 6.2L heavy—duty diesel engine. The E.0. D—161—18 currently exempts Bank‘s Turbocharger System Model 6.2G from the prohibitions of Vehicle Code (VC) Section 27156 for 1982—1991 model year Chevrolet/GMC vehicles pqwered by a 6.2L heavy—duty diesel engine. II. CONCLUSION Since the 1992 model year 6.2L Chevrolet/GMC heavy—duty diesel engine is carried over from the previous year for which an exemption has been granted and the snap—idle test results indicate that smoke opacity of the modified vehicle was less than the 40 percent standard, the staff believes that the add—on turbocharger system will have no adverse effect on exhaust emissions from the engine for which the exemption update is requested. III. RECOMMENDATIONS The staff recommends that Banks be granted an exemption for the add—on turbocharger system model 6.2G for 1982—1992 model year Chevrolet/GMC vehicles powered by a 6.2L heavy—duty diesel engine and that Executive Order D—~161—26 be issued. IV. TURBOCHARGER KIT DESCRIPTION AND OPERATION The purpose of the Banks turbocharger system is to increase the power output of the engine by compressing the intake charge to pressures above that of the atmosphere. This increased pressure allows a greater charge density to enter the combustion chamber and increase the volumetric efficiency of the engine. The maximum fuel delivery is slightly increased to maintain proper air—fuel ratios when the turbocharger is providing —1—

positive manifold pressure (boost). Maximum positive manifold pressure is limited to 10 psi by the size of the turbine and the compressor. The maximum engine speed is reqgulated by the original equipment manufacturer (OEM) fuel injection governor. Controlling the maximum engine speed also controls the maximum engine turbine speed and corresponding boost pressure. The major components of the kit include a 1.0 air ratio (A/R) Rotomaster Model No. TO4B turbocharger, custom intake and exhaust tubing, air cleaner assembly, brackets, hoses and the hardware necessary to complete the installation. Modification to the OEM emission related parts due to the installation of the turbocharger system include replacement of the air cleaner assembly and replacement of the OEM exhaust system with a 3" diameter exhaust system. To meet the newly implemented opacity standard of 40 percent, Banks has modified the compressor wheel from a U trim compressor wheel to an H3 trim compressor wheel. v. DISCUSSION The applicant is making the add—on Turbocharger System Model 6.2G available for 1992 model year Chevrolet/GMC vehicles powered by a 6.2L heavy—duty diesel engine. Certification documents show that the 1992 model year 6.2L Chevrolet/GMC heavy—duty diesel engine is carried over from the previous year for which the turbocharger system has been exempted. Previous testing of the turbocharger showed no adverse affect on exhaust emissions. However, starting with the 1992 model year heavy—duty diesel vehicles, snap—idle smoke opacity testing was required pursuant to California Code of Regulations (CCR) Section 2182, Heavy—Duty Diesel Vehicle Smoke Opacity Test Procedures. The overall smoke opacity could not exceed 40 percent as required by the CCR Section 2182 (c). In the past, Gale Banks through the Specialty Equipment Manufacturers Association (SEMA), claimed that the current aftermarket turbocharged confiquration could not meet the 40 percent opacity standard because turbochargers do not kick—in immediately : —2—

upon engine start up. Thus, during transient periods, air is momentarily restricted even though fuel is increased, causing an increase in peak smoke. To meet the 40 percent opacity standard, Banks modified the turbocharger system to use a new Schwitzer or Garrett H3 trim compressor wheel (part numbers 166198 and 408105—5371 respectively)}). The H3 trim compressor wheel reduces the response time (boost to fuel) of the turbocharger which has a favorable impact on particulate emissions as well as meeting the 40 percent opacity standard. The new trim compressor wheel does not change the overall characteristics of the turbocharger. The applicant claims no other modifications to the system are necessary for installation on 1992 model year applicable vehicles. Smoke opacity testing was conducted at the Gale Banks Engineering facility using a 1989 GMC truck powered by a 6.2L heavy—duty diesel engine to determine if the vehicle with the turbocharger installed is within the 40 222. ‘ percent standard. Bank‘s opacity readings are shown below. Snap—Idle Smoke Opacity Test Results 30%, 29%, 30% The snap—idle test results indicate that smoke opacity of the modified vehicle was less than 40 percent. This demonstrates that the addition of the Gale Banks Turbocharger System Model 6.2G will not have an adverse effect on emissions for 1982—1992 Chevrolet/GMC 6.2L heavy—duty diesel engine for which the exemption was requested. Banks has sfibmitted all the required information and fulfilled the requirements for an exemption.
