State of California AIR RESOURCES BOARD EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARGER KIT MODEL NO. 6.2G FOR INSTALLATION IN CHEVROLET/GMC HEAVY—DUTY VEHICLES POWERED BY A 6.2 LITER GENERAL MOTORS HEAVY—DUTY DIESEL ENGINE May, 1986

May, 1986 EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARGER KIT MODEL NO. 6.2G FOR INSTALLATION IN CHEVROLET/GMC HEAVY—DUTY VEHICLES POWERED BY A 6.2 LITER GENERAL MOTORS HEAVY—DUTY DIESEL ENGINE by Mobile Source Division State of California AIR RESOURCES BOARD 9528 Telstar Avenue E1 Monte, CA 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY Gale Banks Engineering (Banks) has applied for exemption from the prohibitions in Vehicle Code Section 27156 for their add—on turbocharger kit Model No. 6.2G designed for 1982—1986 Chevrolet/GMC heavy—duty vehicles which are powered by the General Motors 6.2 liter heavy—duty diesel engine. Banks has submitted a completed application and all the required information as well as comparative exhaust emissions data which shows that their kit does not have an adverse effect on the emissions from the vehicles described in the application. Confirmatory testing performed at the Raagen—Smit Laboratory verified the applicant‘s test results. The staff recommends that Banks be granted an exemption for their add—on turbocharger kit and that Executive Order D—161—1 be issued.

EVALUATIQN OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARGER KIT MODEL NO. 6.2G FOR INSTALLATION IN CHEVROLET/GMC HEAVY—DUTY VEHICLES POWERED BY A 6.2 LITER GENERAL MOTORS HEAVY—DUTY DIESEL ENGINE I. INTRODUCTION Gale Banks Engineering (Banks) of 546 Duggan Avenue, Azusa, California 91702, has applied for exemption from the prohibitions of Vehicle Code Section 27156 for their add—on turbocharger kit Model No. 6.2G6 for 1982—1986 Chevrolet/GMC heavy—duty vehicles powered by the 6.2 liter General Motors heavy—duty diesel engine. Banks has submitted a completed application, all the necessary information and comparative exhaust emissions data. II. CONCLUSION Based on the submitted information and the comparative exhaust emissions tests performed on a 1986 Chevrolet Suburban heavy—duty diesel truck, the staff concludes that the installation of the Banks turbocharger kit Model No. 6.26 will not adversely affect exhaust emissions from the vehicles for which the exemption has been requested. III. RECOMMENDATIONS The staff recommends that Banks be granted an exemption for this turbocharger kit for use on 1982—1986 Chevrolet/GMC heavy—duty vehicles powered by the 6.2 liter General Motors heavy—duty diesel engine and that Executive Order D—161—1 be issued. IV. TURBOCHARGER KIT DESCRIPTION The purpose of the Banks turbocharger system is to increase the power output of the engine by increasing the volumetric efficiency of it 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 providing more oxygen for combustion. The maximum fuel delivery is slightly 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}. Maximum positive manifold pressure is limited to 10 psig by the size of the turbine 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 controlled. No OEM emission controls are removed or disconnected when the turbocharger kit is installed. The major components of the system include a 1.0 A/R ratio Rotomaster Model No. TO4B turbocharger, custom intake and exhaust tubing, air cleaner assembly, brackets, hoses and the hardware necessary to complete the installation. Detailed installation instructions are included in every kit to insure that the turbocharger installation is done properly (see Appendix 1). A facsimile of the system identification label is shown in Appendix 2. ¥. TURBOCHARGER KIT EVALUATION Evaluation of the Banks turbocharger kit included analysis of all submitted information to confirm that it meets the requirements for the exemption, a comparison of the submitted exhaust emissions data and a comparison of the confirmatory emissions data generated at the Haagen—Smit Laboratory. The test vehicle was a 1986 Chevrolet Suburban heavy—duty diesel truck with an automatic transmission.

Banks performed comparative exhaust emissions tests at FCI International Testing, Inc., in Santa Ana, CA, on the 1986 Chevrolet Suburban described earlier. The test program used was the "Test Program for Add—On Turbocharger Kits for Heavy—Duty Engines" (see Appendix 3). The results of these tests are shown in Table 1. Table 1 FCI Steady—State Test Results Exhaust Emissions (ppm} Mode HC CO NOx Baseline Idle 17.1 23.3 64.0 Turbo Idle 13.2 18.0 52.0 Percent Change —23 —30 —19 Baseline 20 mph 18.3 46.0 63.0 Turbo 20 mph 20.7 58.0 51.5 Percent Change +13 +26 —18 Baseline 30 mph 18.3 58.0 111.5 Turbo 30 mph 19.2 63.0 109.0 Percent Change +5 +9 —2 Baseline 40 mph 20.7 91.0 169.5 Turbo 40 mph 20.7 80.0 146.0 Percent Change 0 —12 —14 Baseline 50mph 19.2 85.0 257 .0 Turbo 50 mph 20.7 63.0 247.0 Percent Change +8 —26 —4 Baseline 55 mph 25.2 100.0 300.0 Turbo 55 mph 25.2 63.0 300.0 Percent Change 0 —37 0 Confirmatory testing was performed at the Haagen—Smit Laboratory and these results are shown in Table 2.

VI. DISCUSSION The steady—state test results indicate that emissions at some test points were slightly increased, however, the increases are only a few ppm which are well within the sensitivity limits of the instruments. This demonstrates that the addition of the Gale Banks Model 6.26 Turbocharger kit will not have an adverse effect on emissions from the 1982—1986 Chevrolet/GMC heavy—duty diesel vehicles for which the exemption was requested. Banks has submitted all the required information and fulfilled the requirements for an exemption.
