SUMMARY JAM Engineering Corporation (JAM)} has applied for exemption from the prohibitions of Vehicle Code Section 27156 for the JAM Carburetor Conversion Kit No. C—505 using one (1) modified Holley Model No. 4360C, List No. 8677 carburetor. The JAM Carburetor Conversion Kit replaces the original equipment k Solex 4A1 carburetor on 1973—1976 model—year Mercedes—Benz 280, 280c and 280s vehicles. Comparative exhaust emission tests demonstrate that the aftermarket JAM Carburetor Conversion Kit No. C—505 does not adversely affect emissions. Based on the results of the tests and the evaluation of the JAM Carburetor Conversion Kit, the staff recommends that the exemption be granted as requested for the 1973—1976 model—year 280, 280c and 280s vehicles.

INTRODUCTION JAM Engineering Corporation (JAM) of Monterey, California, has applied for exemption from the prohibitions of Vehicle Code Section 27156 for a Carburetor Conversion Kit designated as JAM Kit No. C—505 utilizing one (1) modified Holley Model No. 4360C, List No. 8677 carburetor. The Carburetor Conversion Kit is designed to replace the original equipment manufacturer (OEM) Solex 4A1 4—barrel carburetor as found on 1973—1976 model—year Mercedes~Benz 280, 280c and 280s vehicles equipped with 167.5 cubic inch displacement (CID) 6—cylinder engines. This report describes the evaluation of the JAM Carburetor Conversion Kit and the findings. II. CONCLUSIONS Comparative exhaust emission data and other information submitted by the applicant demonstrated that the JAM Carburetor Conversion Kit No. C—505 meets the Air Resources Board (ARB) requirements for exemption from the prohibitions of Vehicle Code Section 27156. III. RECOMMENDATIONS Based on the submitted comparative emissions data and the confirmatory testing performed by the Air Resources Board (ARB) on the JAM Carburetor Conversion Kit, the staff recommends that JAM be granted exemption from the prohibitions of Vehicle Code Section 27156 for the JAM Carburetor Conversion Kit No. C—505 for 1973—1976 Mercedes—Benz 280, 280c and 280s vehicles.

IV. DEVICE DESCRIPTION The JAM Carburetor Conversion Kit No. C—505 uses one (1) modified Holley Model No. 4360C, List No. 8677, carburetor to replace the OEM Solex 4A1 carburetor for 1973—1976 Mercedes—Benz 280, 280c and 280s vehicles. The Solex carburetor is a progressive two stage four barrel design. The special features of this carburetor are a vacuum controlled throttle — positioner, an automatic engine cooling water temperature controlled choke with electric assist and a vacuum operated float chamber vent valve (See Appendix 1). The vacuum controlled throttle positioner controls exhaust emissions during deceleration by holding the throttle valve open slightly during periods of high manifold vacuum, caused by deceleration, until the engine has returned almost all the way to idle, at which time it allows the throttle to shut back to its idle position. By holding the throttle open slightly additional air is supplied to lean out the normally rich conditions which occur during deceleration, thereby reducing emissions. The electric assist choke controls exhaust emissions by electrically heating the choke thermostat, in addition to the heating it receives from the engine coolant, whenever the engine oil temperature is above 62°F. This causes the choke to open sooner during the warmer seasons of the year. The vacuum operated float chamber vent valve controls float chamber vent such that when the engine is not in operation the float chamber vapors are vented to the carbon canister and when the engine is in operation these vapors are vented into the air cleaner and subsequently drawn into the engine and consumed. The Holley carburetor is a progressive two—stage four—barrel design similar to the Solex 4A1 carburetor (See Appendix 2). The Holley does not utilize a throttle positioner. The Holley uses an electrically heated choke only and does not require engine coolant to circulate through it. The Holley utilizes a mechanically operated float chamber vent valve which duplicates the — 2 —

function of the vacuum operated unit on the Solex 4A1 carburetor. Therefore, when the C—505 kit is installed the throttle positioner system is removed with the Solex carburetor, the choke system is changed from an electrically assisted automatic engine cooling water temperature controlled choke to an electric choke and the vacuum operated float chamber vent valve is substituted with a mechanical float chamber vent valve. The calibration of the Holley carburetor is shown in Appendix 3. The JAM C—505 kit comes complete with the modified Holley carburetor, air cleaner adaptor, installation instructions (See Appendix 4) and all the gaskets and hardware required to properly install the Holley carburetor on the Mercedes—Benz 280 series vehicles. The facsimile of the underhood identification label is shown in Appendix 5. V. DEVICE EVALUATION The applicant performed comparative cold—start CVS—75 exhaust emission tests at Emissions Testing Laboratories of Northern California, San Carlos, California. A 1975 model—year Mercedes—Benz 280c equipped with a 167.5 CID engine and automatic transmission was used as the test vehicle. The baseline test was performed with the Solex 4A1 carburetor. A representative production JAM Kit No. C—505 was used for the comparative tésting. A 1975 model—year vehicle was used as the test vehicle since vehicles of this model—year were required to meet more stringent standards. JAM requested that they be allowed to use a 1975 vehicle because it could be easily procured and it utilizes the same emission control system as the 1976 vehicles. It would be expected that vehicles of previous model—years and the 1976 model—year would meet the respective emissions standards using the same JAM Kit. The applicant‘s submitted comparative exhaust emission data are given in Table 1 (See Appendix 6 for original data sheets).

The results of these comparative emissions tests show that the elimination of the throttle positioner, the substitution of the electrically assisted automatic engine cooling water temperature controlled choke with an all electric automatic choke and the substitution of the vacuum operated float chanber vent valve with a mechanically operated valve does not adversely affect emissions. JAM Engineering Corporation has fulfilled the requirements for exemption of their carburetor conversion kit No. C—505.
