TO4B M2 FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE by 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.)

summMary BAE Turbosystems, of 3032 Kashiwa Street, Torrance, CA 90505, has requested an update to the existing Air Resources Board‘s Executive Order {(E.0.) No. D—97—15. The applicant requested that their add—on turbocharger kit No. TO4B MZ2 be also exempted from the prohibitions in Vehicle Code (V.C.} Section 27156 for the 1984 model—year Airstream motorhomes powered by a 1983 California certified Isuzu six=cylinder heavy—duty diesel engine. Based on: 1) the previous comparative exhaust emission tests performed on a 1981 Airstream motorhome powered by a 1981 Isuzu heavy—duty diesel engine for granting E.0. D—97—5; and 2) the fact that the 1984 Airstream motorhomes are powered by a 1983 Isuzu heavy—duty diese1 engine that is a carry—over engine from 1981 and 1982, the staff concludes that the kit will not adversely affect exhaust emissions from the motorhomes for which update is requested. The staff recommends that BAE Turbosystems be granted their update request to include the 1984 model—year Airstream motorhomes powered by a 1983 California certified Isuzu six—cylinder heavy—duty diesel engine and that Executive Order No. D—97—21 be granted.

EVALUATION OF THE BAE TURBOCHARGER KIT NO. TO4B M2 FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE. I. INTRODUCTION BAE Turbosystems of 3032 Kashiwa Street, Torrance, CA 90505, has requested by letter dated July 18 1983, an update to the existing Air Resources Board‘s Executive Order (E.0.) No. D—97—15. The applicant requested that the exemption from the prohibitions in the Vehicle Code (V.C.) Section 27156 for their add—on turbocharger kit No. TO4B M2 be updated to include the 1984 modeT—year Airstream motorhomes which are powered by a 1983 California certified Isuzu Motors Limited six—cylinder heavy—duty diesel engine. II. CONCLUSION Based on: 1) the previous comparative exhaust emission tests performed on a 1981 Airstream motorhome powered by a 1981 Isuzu heavy—duty diesel engine for granting E.0. D=97—5; and 2) the fact that the 1984 Airstream motorhomes are powered by a 1983 Isuzu heavy—duty diesel engine that is a carry—over engine from 1981 and 1982, the staff concludes that the kit will not adversely affect exhaust emissions from the motorhomes for which update is requested. III. RECOMMENDATIONS The staff recommends that BAE Turbosystems be granted their update request to include the 1984 model—year Airstream motorhomes powered by a 1983 California certified Isuzu six—=cylinder heavy—duty diesel engine and that Executive Order No. D—97—21 be granted.

IV. TURBOCHARGER KIT DESCRIPTION The purpose of turbocharging an engine is to increase the volumetric efficiency of an engine by forcing more air into an engine than it would take in under naturally aspirated conditions. The major components of the BAE Turbosystems turbocharger kit are a 0.96 A/R ratio AiResearch turbocharger model No. TO4B M2, an exhaust manifold to turbocharger adaptor, and an intake pipe. The components are packaged with installation hardware and instructions to complete the kit. The exhaust manifold to turbocharger adaptor is installed on the OEM exhaust manifold located on the driver‘s side of the engine. The turbine inlet of the turbocharger mounts directly to the adaptor. The turbine, driven by exhaust gases, is Tinked to the compressor by a solid shaft. Compressed incoming air is routed to the intake manifold through the BAE Turbosystems intake pipe mounted transversely over the engine. Maximum positive manifold pressure (boost) is lTimited to 13 psig by the size of (and exhaust flow through) the turbine housing. No wastegate or other active boost lTimiting device is used. The cooling of the turbocharger is achieved by direct fan air from the engine and Tubricating oi1 passing through the unit. The oil is piped from the filtered main oil galley to the turbocharger bearing housing. Qi1 from the turbocharger is returned to the oi1 pan. No modifications to the OEM tune—up specifications are required when the turbocharger kit is installed. V. TURBOCHARGER KIT EVALUATION The detafled description of the Air Resources Board‘s evaluation of the kit is included in the ARB Staff Report titled "Evaluation of the BAE Turbocharger Kit No. TO4B M2 for Compliance with the Requirements of Section 27156 of the Vehicle Code," dated June 5, 1981. — 2 —

VI. DISCUSSION E.0. No. D—97—15 was granted for 1981, 1982 and 1983 model—year Airstream motorhomes powered by a 1981 or 1982 California certified Isuzu Motors Limited six—cylinder heavy—duty diesel engine. The applicant now intends to use its turbocharger kit No. TO4B M2, using the same 0.96 A/R ratio AfResearch turbocharger, for the 1984 model—year Airstream motorhomes powered by a 1983 California certified Isuzu Motors Limited six—cylinder heavy—duty diesel engine and equipped with automatic transmissions. The applicant, therefore, is requesting that the exemption for this turbocharger kit be updated to include these 1984 model—year motorhomes \ as well. In response to the request, the staff compared the design of 1981, 1982, and 1983 model—year Isuzu heavy—duty diesel engines. In particular, the effects the turbocharger kit might have on the vehicle‘s emissions were evaluated. Since the 1983 model—year California certified Isuzu heavy—duty diesel engine (used for the 1984 model—year motorhomes) are carry—over {identical engine design) from the 1981 and 1982 model—year California certified Isuzu engines used in the 1982 and 1983 model—year motorhomes, respectively, the staff is of the opinion that the turbocharger kit will have the same degree of performance/emissions impact on the motorhomes for which an update is requested. Since the test data on a 1981 model—year Isuzu engine show that the exhaust emissions were not adversely affected when the turbocharger kit was installed, the staff is of the opinion that the kit will have no adverse emission effect on the 1984 modeT—year motorhomes for which an update is requested. —3 —
