D—171—1 dated December 17, 1988. E.0. D—171—1 exempted the ATS turbocharger kit mode! No. ATS 6.9L from the prohlbitions in Vehicle Code Section 27156 for 1983—1987 model—year Ford Motor Company heavy—duty vehicles powered by a 6.9 liter Navistar international heavy—duty diesel engine. The applicant has requested that the exemption be updated to include the 1988 model—year Ford Motor Company heavy—duty vehicles powered by a 7.3 liter Navistar International heavy—duty diese! engine. 11. conckusion v Based on the following: (1) the fact that the kit applicable to 1988 model—year 7.3 liter Navistar International heavy—duty diesel engine is identical to the exempted kit; (2) the fact that the 1988 7.3 liter Navistar International heavy—duty diesel engine is a replacement engine for the 1987 6.9 liter Navistar International heavy—duty diesel engine and that both engines have similar designs; (3) the test data from previous comparative exhaust emission tests and back—to—back crankcase pressure tests performed for exempting the kit; and (4) that the engine design complies with the carriéver criteria as outlined in EPA‘s Advisory Circulars 17F and 208B, the staff believes that the add—on turbocharger kit will have no adverse effect d L on the engines for whlcq«exemption update is requested.

111. RECOMMENDATIONS The staff recommends that ATS be granted an update as requested, and L that Executive Order D—171—2 be Issued. 1v. TURBOCHARGERKITDESCRIPTIONANDOPERATION 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 slightly Increased in order to maintain proper air—fue! 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 (AiResearch) mode! No. TO4B, custom intake and exhaust tubing, air cleaner assembly, brackets, hoses and the hardware necessary to complete the Installation. The OEM crankcase depression reguiator is removed and replaced with tubing, flttings with a 0.375" orifice suppiied in the kit. A complete air cleaner assembly is supplled with the system to replace the stock alr cleaner assembly. No other emission—related components are removed or disconnected when the turbocharger kit is Iinstalled. Maximum positive manifold pressure is [imited 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 instailation of the kit. Therefore, by controlling maximum engine speed, maximum turbine speed and corresponding boost pressures are also controlled. D1SCUSS!ON ATS add—on turbocharger kit mode! No. ATS 6.9L is designed for _2~

installation on 1983—1987 model—year Ford Motor Company vehicles powered by a 6.9 liter Navistar International heavy—duty diese! engine. The exemption was granted on the basis that the effectiveness of the vehicle‘s poliution control system was not reduced. Evaluation consisted of comparative (baseline versus turbocharged) steady state tests and back—to—back crankcase —pressure tests. The applicant is making available the add—on turbocharger kit mode! No. ATS 6.9L/7.3L for the 1988 model—year Ford Motor Company vehicles powered by a 7.3 liter Navistar International heavy—duty diesel engine. The applicant claims that no modifications to the kit are needed In order to be compatible with the 1988 mode!s. They have requested that the exemption be updated to include these 1988 model—year vehicles. In response to the applicant‘s request, the staff compared the engine design of 1987 and 1988 model—year Ford Motor Company vehiclies powered by a 6.9 or a 7.3 liter Navistar international heavy—duty diesel engine. Certification documents and correspondence from Navistar international to the ARB indicated that the 1988 model—year 7.3 liter engine is the replacement engine for the 1987 model—year 6.9 liter engine. The staff also noted that the engine designs of both 1?87 and 1988 engines are similar. Because the data on a 1986 6.9L ;fi;zflvehlcle showed that the emissions were not adversely affected when the turbocharger kit was Installed;%}; back—to—back crankcase pressure tests on five vehicles did not show significant effect on crankcase pressure and that the engine design complies with the carr&iover criteria as outlined in EPA‘s Advisory circulars 17F and 20B, the add—on turbocharger kit will have no adverse effect on the 1988 model—year Ford Motor Company heavy—duty vehicles powered by a 7.3C/M:;}star International heavy—duty diese! engine. No additional testing was required or performed for updating the exemption as requested. —3—
