SUMMARY Advanced Turbo Systems, Inc. (ATS) has requested an update to Executive Order D—171—2, which exempts their turbocharger kit Model No. ATS 6.9L/7.3L for 1983—1987 model—year Ford Motor Company heavy—duty vehicles powered by a 6.9 Liter Navistar International heavy—duty diesel engine and 1988 model—year Ford heavy—duty vehicles powered by a 7.3 liter Navistar heavy—duty diesel engine. They have requested that the exemption be updated to include the 1989 mode!— year Ford heavy—duty vehicles powered by a 7.3 liter Navistar heavy—duty diese! engine. Based on the fact that (1) there is no emissions—related difference between the 1988 and the 1989 model—year versions of the 7.3 liter Navistar heavy—duty diesel engine and (2) no emissions—related variations to the retrofit turbocharger kit Model No. ATS 6.9L/7.3L have been made for applicatlon to the 1989 model—year version of the 7.3 liter Ford/Navistar heavy—duty diesel engine, the staff believes that the add—on turbocharger kit will have no adverse emissions effect on the engine for which the exemption update is requested. The staff recommends that ATS be granted an update as requested and that Executive Order D—171—4 be issued.

EVALUATION OF ADVANCED TURBO SYSTEMS, INC. ADD—ON TURBOCHARGER KIT MODEL NO. ATS 6.9L/7.3L FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE 1. INTR TION Advanced Turbo Systems, Inc. (ATS) of 5919 South 350 West, Murray, UT 84107, has requested an update to the existing Air Resources Board Executive ofder (E.0.) D—171—2 dated March 31, 1988. E.0. D—171—2 exempted the ATS turbocharger kit Mode! No. ATS 6.9L/7.3L from the prohibitions in Vehicle Code Section 27156 for 1983—1987 model—year Ford heavy—duty vehicles powered by a 6.9 liter Navistar heavy—duty diesel! engine and the 1988 model—year Ford heavyj duty vehicles powered by a 7.3 liter Navistar heavy—duty diesel engine. The applicant has requested that the exemption be updated to Include the 1989 model—year Ford heavy—duty vehicles with a 7.3 liter Navistar heavy—duty diese! engine. 11. LUS ION Based on the fact that (1) there is no emissions—related difference between the 1988 and the 1989 model—year versions of the 7.3 liter Navistar heavy—duty diese! engine and (2) no emissions—related variations to the retrofit turbocharger kit Mode! No. ATS 6.9L/7.3L have been made for application to the 1989 model—year version of the 7.3 liter Ford/Navistar heavy—duty diesel engine, the staff believes that the add—on turbocharger kit will have no adverse emissions effect on the engine for which the exemption update is requested. LH. RECOM DAT ION The staff recommends that ATS be granted an update as requested, and that E.0. D—171—4 be Issued.

IV. TURBOCHARGER KIT DESCRIPTION AND OPERATION The purpose of the ATS turbocharger kit is to Increase the power output of the engine by increasing its volumetric efficiency. 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 fuel delivery is stightly 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 0.96 A/R ratio Rotomaster (AirResearch) Mode! No. TO48, custom intake and exhaust tubing, air cleaner assembly, brackets, hoses and the hardware necessary to complete the installation. The OEM crankcase depression regulator is removed and replaced with tubing, fittings with a 0.375" orifice suppl]ed in the kit. A complete air cleaner assembly is supplied with the system to replace the stock air cleaner assembly. No other emission—related components are removed or disconnected when the turbocharger kit is installed. Maximum positive manifold pressure is limited to 12 psi by the size of the turbine and the compressor. The maximum engine speed is regulated by the OEM fue! Injection governor which is not modified by the installation of the kit. Therefore, by controlling maximum engine speed, maximum turbine speed and corresponding boost pressure are also controlled. v. D LQN ATS add—on turbocharger kit Mode! No. ATS 6.9L/7.3L is designed for Installation on 1983—1987 modei—year Ford vehicles powered by a 6.9 l|iter . Navistar heavy—duty diesel engine and 1988 mode! year Ford vehicles powered by a 7.3 liter Navistar heavy—duty diesel engine. The exemption was granted on —2—

the basis that the test data from comparative exhaust emission tests and back— to—back crankcase pressure tests performed for exempting the kit showed no reduction in the effectiveness of the vehicle‘s pollution control system. The applicant is making available the add—on turbocharger kit Mode! No. ATS 6.9L/7.3L for the 1989 model—year Ford vehicles powered by a 7.3 liter Navistar heavy—duty diesel engine. The applicant claims that no modifications to the kit are needed in order to be compatible with the 1989 models; They have requested that the exemption be updated to include these 1989 model—year vehicies. In response to the applicant‘s request, the staff compared the engine design of 1988 and 1989 mode!—year Ford vehicles powered by a 7.3 liter Navistar heavy—duty diesel engine. Certification documents indicated that there is no emissions—related difference between the 1988 and the 1989 mode!— year versions of the 7.3 liter Navistar heavy—duty diesel engine. Also no emissions—related varliations to the retrofit turbocharger kit Model No. ATS 6.9L/7.3L have been made for application to the 1989 model—year version of the 7.3 \iter Ford/Navistar heavy—duty dissel engine. Based on these facts, no additional testing was required or performed for updating the exemption as requested.
