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.)

summary Redline, Inc., a distributor of Italian made Weber carburetors, has applied for exemption from the prohibitions of Vehicle Code Section 27156 for the Redline Carburetor Exchange Kit No. K8904 using one (1) Weber model 32/36 DGEV33B1 carburetor. The Redline Carburetor Exchange Kit replaces the original equipment S.U. HIF6, HS or HD l—barrel carburetors or the original equipment Zenith—Stromberg 175—CD—2 1—barrel carburetors on 1968—72 model—year Volvo vehicles. The original equipment air cleaner is not retained in the Redline Kit installation. The Redline Carburetor Exchange Kit utilizes an open type air cleaner which the staff has determined does not increase evaporative emissions. An anti—dieseling solenoid is installed in the idle circuit of the Weber carburetor to prevent the engine from running on after the engine has been shut off. Comparative exhaust emission tests demonstrate that the aftermarket Redline Carburetor Exchange Kit No. K8904 using one Weber model 32/36 DG@EV33B1 carburetor does not adversely affect emissions. Based on the results of the tests and the evaluation of the Redline Carburetor Exchange Kit, the staff recommends that the exemption be granted as requested for the 1968—72 model—year Volvo vehicles equipped with B18, B20 or B208 engines.

EVALUATION OF THE REDLINE CARBURETOR EXCHANGE KIT NO. K8904 USING MODEL 32/36 DGEV33B1 WEBER CARBURETOR FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CoDE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE I. INTRODUCTION Redline, Inc. of Torrance, California, a subsidiary of Imported Parts and Accessories Corporation (IMPAC), is a distributor of Italian made Weber carburetors. The company has applied for exemption from the prohibitions of Vehicle Code Section 27156 for a Carburetor Exchange Kit designated as Redline Kit No. K8904 utilizing one (1) Weber model 32/36 DGEV33B1 carburetor. The Carburetor Exchange Kit is designed to replace the two (2) original equipment manufacturer (OEM) constant velocity carburetors as found on 1968—1972 model—year Yolvo vehicles equipped with B18, B20 or B20B engines. This report describes the evaluation of the Redline Carburetor Exchange Kit and the findings. II. CONCLUSION Comparative exhaust emission data and other information submitted by the applicant demonstrated that the Redline kit using one {1) Weber model 32/36 DGEV33B1 carburetor meets the Air Resources Board (ARB) requirements for exemption from the prohibitions of Vehicle Code Section 27156. III. RECOMMENDATION Based on the submitted comparative data of the Redline Carburetor Exchange Kit, the staff recommends that Redline, Inc. be granted exemption from the prohibitions of Vehicle Code Section 27156 for the Redline Carburetor Exchange Kit No. K8904 using one (1) model 32/36 DGEV33B1 Weber carburetor for 1968—72 model—year Volvo vehicles equipped with B18, B20 or B208B engines.

IV. DEVICE DESCRIPTION The Redline Carburetor Exchange Kit No. K8904 uses one (1) Weber model 32/36 DGEV33B1 carburetor to replace the two (2) OEM constant velocity carburetors. The OEM carburetors are of the single barrel sidedraft design; the venturi area is automatically changed according to engine air intake. The amount of fuel passing through the main jet is governed by a tapered needle which moves proportional to the engine air intake. A choke valve and auxiliary nozzle are used for cold starting. Main components of the carburetor consist of: a float chamber, suction chamber, suction piston, piston damper, metering needle and jet, throttle valve body, choke valve and auxitiary nozzle (See Appendix A). The Weber 32/36 DGEV33B1 carburetor is a progressive two—barrel down— draft design (see Appendix A). The Weber carburetor uses a mechanically— operated secondary which starts to open after the primary throttle opens approximately 68 percent. A diaphragm type accelerator pump is actuated by throttle movement and injects fuel into the primary barrel. The Weber is fitted with an anti—dieseling valve in the idle circuit which shuts off the fuel supply to the idle circuit whenever the ignition is switched off. The addition of this anti—dieseling valve upgrades the emission control of the Volvo vehicles since the OEM carburetors were not equipped with such a device. The calibration of the Weber carburetor is included in Appendix B. The DGEY model Weber carburetor is fitted with an electric choke which is more precise and consistent than the manual choke used on the OEM carburetors. Included in the Redline kit is the Weber carburetor, intake manifold, air cleaner, throttle linkage, and all necessary hoses, clamps and fasteners needed to install the Weber carburetor correctly.

¥. EVALUATION PROGRAM The applicant performed comparative CVS—75 exhaust emission tests at Import Certification Laboratories in Anaheim, California. A 1970 Volvo equipped with a 820 engine and 4—speed manual transmission was used. The baseline test was performed with the OEM carburetors. A representative production Redline Kit No. K8904 was used for the comparative testing. The results of those tests are in Table 1. Table 1 Exhaust Emissions gm/mi Fuel Economy Condition HC CO NOx City mi/gal Baseline 4.5 53.3 2.3 17.8 Redline Kit 3.9 55.4 1.9 17.8 A 1970 model—year vehicle was used as the test vehicle. It would be expected that vehicles of previous model—years would have the same degree of performance/emissions impact as the vehicle tested when using the same Redline Kit. The applicant performed comparative evaporative emissions testing to demonstrate that the open—element air cleaner does not increase the evaporative emissions from the Volvo vehicles. The same 1970 Volvo was tested using the Sealed Housing Evaporative Determination (SHED) procedures. The results of these tests are shown in Table 2. Table 2 Evaporative Emission Test Data SHED Condition Evaporative Emissions gm/test BaseTine 12.2 Redline Kit No. K8904 6.0

VI. DISCUSSION The applicant‘s submitted comparative emissions test data are acceptable. The comparative data show that the HC and NOx emissions are below the baseline values. The change in carbon monoxide emissions is within the limits of test variability. The evaporative emissions decreased by more than 50%, as compared to the baseline, with the Weber carbuetor and open type air cleaner installed. The kit provides the necessary components and installation instructions to allow the average mechanic to connect the OEM emission controls to the new intake manifold and carburetor so that they function properly. This kit offers an economical alternative to the repair or replacement of the OEM constant velocity carburetors. Since the Volvo vehicles are equipped with dual carburetors which require synchronization {an adjustment/balancing procedure which requires special tools and a qualified mechanic) on a regular basis while the single Weber does not, the vehicles will stay in tune longer with the Weber carburetor.
