State of California AIR RESOURCES BOARD Staff Report Evaluation of Cummins West, Inc., Engine Modifications in Accordance With Section 2222, Title 13 of the California Administrative Code I. INTRODUCTION Cummins West, Incorporated, of San Francisco, California, and Cummins Service and Sales, Inc., of Los Angeles, California, are independent corporations franchised by Cummins Engine Company, Incorporated, to provide aftermarket engines, parts, and service for users of diesel Cummins engines in California. Cummins West, Inc., acting in behalf of both companies, has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for an uncertified engine configuration. These Cummins franchises propose to upgrade older certified engines to the hybrid specification which utilizes some components of more recent engines. The purpose of this modification is to improve fuel economy. 11. DEVICE DESCRIPTION The applicant proposes two different parts packages to be used in rebuilding certain 1973 through 1978 Cummins 855 CID engines. One will produce 300 HP, the other 350. These packages will replace nine existing engine configurations. Tables I and II list these parts. TableIII contains the injector timing specifications.

The fuel injection rate is controlled by the output pressure of the injection pump. This pressure is a complex function of engine speed and power demand. The power curve of the engine is defined by the pump calibration. Cummins Engine Company has thousands of these calibrations. The count of the calibrations applicable to CPL 021 and 024, respectively, is 37 and 8. Cummins West has submitted two additional calibrations which are not in the Cummins list. The 350 HP calibration is very similar to the 3077 calibration of the CPL 024 engine which meets 1975—76 standards. The 300 HP calibration does not appear to closely match any published calibration. It is simtlar, however, to a 1974 calibration from CPL 174. III. DEVICE EVALUATION On October 29 contact was made with Mr. Robert Ryan of the Cummins Engine Company‘s Engine Certification Laboratory in Columbus, Indiana. He is of the opinion that these modifications will have no adverse effect upon emissions. He also stated that Cummins West had submitted a modified engine to the evaluation. Emissions testing of the engine was to be conducted in about three weeks from that date. Although it is probable that the selected components will assemble into an engine which meets the 1977—78 California emissions standards, it is felt, that without supporting test data, the staff can only predict with reasonable certainty that the 1974 California and 1978 federal standards will be met. IV. RECOMMENDATION The staff finds that the Cummins West modification to Cummins 855 CID Cummins diesel engines will not result in increased emissions from engines designed to meet the 1974 and earlier California or 1978 and earlier federal emissions standards. It is, therefore, recommended that E.0. D—120 be granted.
