STATE OF CALIFORNIA AIR RESOURCES BOARD EVALUATION OF DIESEL RESEARCH AND DEVELOPMENT CORPORATION‘S TURBOCHARGER KIT NO. 4B2 FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 of THE CALIFORNIA ADMINISTRATIVE CODE AVGUST 8, 1983

August 8, 1983 EVALUATION OF DIESEL RESEARCH AND DEVELOPMENT CORPORATION‘S TURBOCHARGER KIT NO. 4B2 FOR EXEMPTION FROM THE PROHIBITIONS IN VEKHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE ins. by MOBILE SOURCE CONTROL DIVISION State of California AIR RESOURCES BOARD 9528 Telstar Avenue EI 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 commerical products constitute endorsement or recommendation for use.)

SUMMARY Diesel Research and Development Corporation (DRDC) has applied for exemption of an add—on turbocharger kit from the prohibitions in Vehicle Code Sectton 27156. The kit, turbocharger kit number 4B2, is intended for installation on 1983 and o]der model—year Mercedes Benz 240D modet!s powered by a four—cylinder diesel engine of 146 CID. Emission test results submitted by DRDC and generated at the ARB test facility indicate that the add—on turbocharger kit number 482 will not significantly affect emission from vehicles for which exemption is requested. Based on the above, the staff recommends that DRDC be granted an exemption as requested and that Executive Order D—=135 be granted.

EVALUATION OF DIESEL RESEARCH AND DEVELOPMENT CORPORATION‘S TURBOCHARGER KIT NO. 4B2 FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE I. INTRODUCTION Diese! Research and Development Corporation (DRDC), of 2741 Toledo Street, Suite 218, Torrance, California 90503, has applied for exemption of an add—on turbocharger kit from the prohibitions in Vehicle Code Section 27156. The kit, turbocharger kit number 4B2, is intended for installation on 1983 and older modeT—year Mercedes Benz 2400 models powered by a four—cylinder diese1 engine of 146 cubic inch displacement. DRDC has submitted data from back—=to—back emtssion tests conducted on a semms., 1982 Mercedes Benz 240D at FCI International Testing Laboratory in Santa Ana, California. Confirmatory tests were conducted on the same vehicle at the Air Resources Board (ARB) Taboratory in E1 Monte, California. II. CONCLUSION Emission test results submitted by DRDC and generated at the ARB test facility indicate that the add—on turbocharger kit number 4B2 will not significantly affect emissions from vehicles for which exemption is requested. III. RECOMMENDATIONS Based on the above conclusion, the staff recommends that DRDC be granted an exemption as requested and that Executive Order D—135 be granted.

IV. TURBOCHARGER KIT DESCRIPTION AND OPERATION The purpose of turbocharging is to increase the volumetric efficiency of an engine. The major components of the DRDC turbocharger kit number 4B2 are a 0.4 A/R ratio Rotomaster/Rajay turbocharger, an air filter box, a replacement cast aluminum intake manifold, and a replacement cast ifjron exhaust manifold. The components are packaged with installation hardware and instructions and sold as a kit. The original equipment manufacturer‘s (OEM) exhaust manifold is replaced by the DRDC fron manifold. The turbine inlet of the turbocharger mounts directly on the replacement manifold. The turbine, driven by exhaust gases, is lTinked to the compressor by a solid shaft. Intake air is drawn through the add—on air filter and compressed by the compressor. Compressed atr is then fed into the engine through the DRDC cast aluminum intake manifold. Maximum positive manifold pressure (boost) is limited to 12 psig by the size of (and exhaust flow through) the turbine housing. No wastegate or other active boost Timiting device is used. The cooling of the turbocharger is achieved by lubricating oil passing through the unit. The oil is delivered {using a special oil supply lTine) from a hole tapped at the oil filter cover plate to the turbocharger bearing housing. Oil is returned gravitationally to the engine oil pan. No modifications to the OEM tune—up specifications are required or permitted when the turbocharger kit is installed. V. TURBOCHARGER KIT EVALUATION A 1982 Mercedes Benz 2400 mode] powered by a four—cylinder diesel engine was used for the evaluation of the turbocharger kit. A description of the vehicle and test parameters is given in the Appendices.

Evaluation consisted of comparative (without and with the kit installed on the test vehicle) cold—start CVS—75 and hot—start Highway Fuel Economy tests for measuring exhaust emissions and fuel economy. Tests were performed under contract for DRDC by FCI International Testing Laboratory and confirmed by the Air Resources Board laboratory. A synopsis of the test data is tabulated in the Appendices. VI. DISCUSSION Due to the high cost and availability of obtaining a Mercedes Benz as a test vehicle, and the fact that the 1983 Mercedes Benz 2400 models are carry—over (identical engine design) from the 1982 model—year, the staff accepted a 1982 model as a test vehicle. Exémption coverage is requested for 1983 and older model—year Mercedes Benz 240D models. The comparative CVS—75 emissions test data generated by the Air Resources Board show increases of hydrocarbon emissions (0.07 grams per mile) with the turbocharger installed. Because of Timited applications of this turbocharger (Mercedes Benz 240D models only), the overall emissions impact is considered by the staff insignificant. The above results satisfy the Air Resources Board‘s requirements for granting DRDC an exemption for their 482 turbocharger kit as requested.
