SUMMARY Gale Banks Engineering (Banks) has requested an update to Executive Order D—161—17, which exempts their Turbocharger System Model 6.9F from the prohibitions in Vehicle Code Section 27156, to include the 1992 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy— duty diesel engine. The 1992 model year 7.3L Navistar International 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 mm that Executive Order D—1651—25 be issued. i

EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARGER SYSTEM MODEL 6.9F 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 Executive Order (E.0O.) D—161—17 to include the 1992 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. The E.0. D—l61—17 currently exempts Bank‘s Turbocharger System Model 6.9F from the prohibitions of Vehicle Code (VC) Section 27156 for 1988—1991 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. II. CONCLUSION Since the 1992 model year 7.3L Navistar International heavy—duty diesel engine is carried over from the previous year for which an exemption has (f9m., 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 6.9F for 1988—1992 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine and that Executive Order D—161—25 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 —~1—

efficiency of the engine. The maximum fuel delivery is slightly increased to maintain proper air—fuel ratios when the turbocharger is providing positive manifold pressure (boost). Maximum positive manifold pressure is limited to 7 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 or a Schwitzer/Banks Model No. TO4B2S turbocharger, custom intake and exhaust tubing, air cleaner assembly, brackets, hoses and the hardware nécessary 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. Also, the fuel setting is reduced five (5) percent for 1992 models by turning the fuel pump adjustment screw 60 degrees (1/6 turn clockwise}, instead of the 90 degrees (1/4 turn clockwise) adjustment for the previous models. v. BISCUSSION The applicant is making the add—on Turbocharger System Model 6.9F available for 1992 model year Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—duty diesel engine. Certification documents show that the 1992 model year 7.3L Navistar International 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 —2«—

year heavy—duty diesel vehicles, snap—idle smoke opacity testing was required pursuant to California Code of Reqgulations (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 configuration could not meet the 40 percent opacity standard because turbochargers do not kick—in immediately 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 m 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. Furthermore, the fuel setting for 1992 model year California certified engines is reduced five (5) percent due to the snap idle test requirements. Since the H3 trim wheel does not change the overall characteristics of the turbocharger and the fuel adjustment (90 degrees or 1/4 turn clockwise) of previous model years represent the ‘worst case‘ condition, no additional emission testing (other than the smoke opacity test) was required. 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 1991 Ford Super—Duty truck powered by a 7.3L Navistar on International heavy—duty diesel engine to determine if the vehicle with the —3—

turbocharger installed is within the 40 percent standard. Bank‘s opacity readings are shown below. Snap—Idle Smoke Opacity Test Results 22%, 23%, 22% 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 6.9F will not have an adverse effect on emissions for 1988—1992 Ford Motor Company vehicles powered by a 7.3L Navistar International heavy-duty diesel engine for which the exemption was requested. Banks has submitted all the required information and fulfilled the requirements for an exemption.
