SUMMARY * Gale Banks Engineering (Banks) has requested an update to Executive Order D~161~3, which exempts their turbocharger kit mode! No. 6.2G for 1982— 1987 model—year‘Chevrolet/GMC heavy—duty vehicles powered by a 6.2 liter General Motors heavy—duty diesel engine.~ They have requested that a turbocharger unit manufactured by an additional source (Schwitzer/ Banks) be also exempted. Based ofi the following: (1) comparative compressor performance maps submitted by Banks indicating that the two turbochargers have simllar operating characteristics; (2) the fact that both turbochargers have an A/R ratio of 1.0; and (3) test data from previous comparative exhaust emission tests performed for exempting the kit, the staff concludes that the Banks ‘ turbocharger k{t mcdél No. 6.2G using the Schwitzer/Banks turbocharger wili not adversely affect exhaust emissions from 1982—1987 model—year Chevrolet/GMC heavy—duty vehicies powered by a 6.2 liter General Motors heavy—duty diese! engine.

EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARGER KIT MODEL NO. . 6.2G FOR INSTALLATION IN CHEVROLET/GMC HEAYY—DUTY VEHICLES POWERED BY A 6.2 LITER GENERAL MOTORS HEAVY—DUTY DIESEL ENGINE FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WiTH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE 1. JNTRODUCTION Gale Banks Engineering (Banks) of 546 Duggan Avenue, Azusa, California 91702, has requested an update to the existing Air Resources Board Executive Order (E.0.) D—161—3 dated October 23, 1986. E.0. D—161—3 exempted the Bank‘s turbocharger kit mode! No. 6.2G from the prohibitions in Vehicle Code Section 27156 for 1982—1987 model—year Chevrolet/GMC heavy—duty vehicies powered by a 6.2 liter General Motors heavy—duty diesel enéine, The applicant has requested that a turbocharger unit (the major component of the kit) manufactured by an additional source (Schwitzer/Banks) be also exempted. This would give Banks the freedom to procure turbocharger units from two sources when assembling the kits for saile. [E. NCLUS ION Based on the following: (1) comparative compressor performance maps submitted by Banks Indicating that the two turbochargers have similar operating characteristics; (2) the fact that both turbochargers have an A/R ratio of 1.0; and (3) test data from previous comparative exhaust emission tests perférmed for exempting the kit, the staff conciudes that the Banks turbocharger kit mode! No. 6.2G using the Schwitzer/Banks turbocharger wil| not adversely affect exhaust emissions from 1982—1987 model—year Chevrolet/GMC heavy—duty vehicles powered by a 6.2 liter General Motors heavy—duty diesel engine.

LEH. RECOMMENDAT IONS = The staff recommends that Banks be granted an update as requested, and that Executive Order D—161—7 be issued. lV.< RBOCHARGER KIT DESCRIPTION AND OPERATION The purpose of the Banks turbocharger klt is to increase the power outpuf of the engine by Iincreasing Its volumetric eff?ciency. This is accomplished by compressing the intake charge to pressures above that of the atmosphere. The increased pressure allows a greater charge density to enter the combustion chamber providing more oxygen for combustion. The maximum fue! delivery is siightly increased in order to maintain proper air—fuel ratios with the increased air flow from the turbocharger when it is providing positive manifold pressure (boost). The major components of the kit Include a 1.0 A/R ratio Rotomaster model No. TO4B or a Schwitzer/Banks Model No. TO4B2§5 turbocharger, custom Intake gnd exhaust tubing, air cleaner assembly, brackets, hoses and the hardware necessary to complete the installation. Maximum positive manifold pressure is limited to 10 psi by the size of the turbing and the compressor. The maximum engine speed is regulated by the OEM fuel injection governor which is not modified by the installation of the kit. Therefore, by controlling maximum engine speed, maximum turbine speed and corresponding boost pressures are also contrdlled. No OEM emission controls are removed or disconnected when the turbocharger kit is installed. v. D1SCUsSS ION Banks has submitted compressor performance maps of both Rotomaster Mode! No. TO4B and Schwitzer/Banks mode! No. TO4B2S turbochargers. Both

turbochargers are designed to have an A/R ratio of 1.0 (critical parameter). The compressor maps indicate that the two turbochargers have similar operating characteristics. A copy of the compressor maps is appended.
