EVALUATION OF THE REDLINE CARBURETOR CONVERSION KIT NO. K8625 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 Compton, 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 Conversion Kit designated as Redline Kit No. K8625 using a Weber carburetor to replace the original equipment manufacturer (OEM) Hitachi two—barrel carburetors found on the following vehicles: Vehicle Model Red1ine Weber Year(s) Make or_Engine Type Kit No. Carb. Model No. 1979—1982 Datsun 210 models K8625 32/36 DGAV 33B1 This report describes the evaluation of the Redline Carburetor Conversion Kit and the findings. II. CONCLUSION Comparative exhaust emission data and other information submitted by the applicant demonstrated that the Redline Kit No. K8625 using a Weber carburetor meets the Air Resources Board (ARB) requirements for exemption from the prohibitions of Vehicle Code Section 27156. III. RECOMMENDATION Based on the submitted information and the emissions test data on the Redline Carburetor Conversion Kit, the staff recommends that Redline, Inc. be granted exemption from the prohibitions of Vehicle Code Section 27156 for the Redline Carburetor Conversion Kit No. K8625 for use on the vehicles described above and that Executive Order No. D—133—10B be issued.

IV. DEVICE DESCRIPTION The Redline Carburetor Conversion Kit No. K8625 uses one (1) model 32/36 DGAV 33B1 Weber carburetor as an economical replacement for the OEM carburetors found on the 1979—1982 Datsun vehicles described previously. These Datsun vehicles are equipped with a Hitachi carburetor. These Hitachi carburetors are of the progressive two—barrel design (See Appendix 1). The Weber 32/36 DGAV 33Bl is a progressive two—barrel carburetor which is similar in basic design to the OEM carburetors (See Appendix 2). It has provisions for vacuum operated emission control systems, including distributor vacuum advance/retard units, EGR and air injection control systems. A variety of emission control devices are used on these vehicles. Some are integral to the OEM carburetor and others are external devices which either control specific functions of the OEM carburetor or are activated by movement of the throttle. The installation of the Weber carburetor retains most of these devices or duplicates the functions of the devices in a different manner, however, some devices cannot be retained. These devices and their disposition after the intallation of the Weber carburetor are: 1) The Fuel Shut—off Vacuum Switch, on vehicles so equipped, is disconnected and removed 2) The Throttle Positioner or Dashpot, on vehicles so equipped, is disconnected and removed. 3) The Throttle Valve Switch, on vehicles so equipped, is disconnected and removed. 4) The Throttle Opener Control System (TOCS}, on vehicles so equipped, is disconnected and removed. 5) The Altitude Compensator, on vehicles so equipped, is disconnected and removed. 6) The Mixture Ratio Control Valve, on vehicles so equipped, is disconnected and removed.

For details of which devices must be disconnected depending on the model—year of the vehicle in question see Appendix 3. The Redline Kits come complete with a Weber carburetor, an air cleaner adaptor, all the hoses, gaskets and hardware necessary to install the Weber carburetor on the Datsun vehicles. Installation instructions, which are included in every kit, show the kit installer how to properly install the Weber carburetor. Vacuum hose routing diagrams, contained in the instructions, show the proper vacuum hose connections to the Weber carburetor (see Appendix 4). An underhood label, included in the kit, is to be affixed to the vehicle near the OEM vacuum hose routing diagram which states that the vehicle is equipped with a Redline Kit and that appropriate vacuum hose routing diagrams may be found in the applicable Redline Kit installation instructions. For persons who may have technical questions or need a copy of a vacuum hose routing diagram, the Redline technical information phone numbers {Tech Lines) are included on this label (see Appendix 5). v. DEVICE EVALUATION ' A carburetor is a critical emissions—related component of a vehicle. Any carburetor conversion, especially one which requires the disconnection of auxiliary emission control components must be evaluated and tested. Comparative exhaust emissions tests have been accepted as a means of determining if the carburetor conversion and the disconnections associated with it will not have an adverse emissions impact. However, the effect of disconnecting an altitude compensator cannot be evaluated by comparative exhaust emissions tests performed at low altitudes. Therefore, a special test program and analytical method was developed for determining the tailpipe air/fuel ratio {TAFR) at elevations of 6000 feet

without an altitude compensator in conjunction with a carburetor conversion. The method was based on the equation presented in ARB‘s manufacturers advisory correspondence (MAC) 78—2, Section II.B.1. According to the California High—Altitude Test Requirements, the TAFR at 6000 feet must be stoichiometric or leaner to demonstrate compliance with the requirements. The test vehicle used for the evaluation was a 1981 Datsun 210 with a 1.5 liter engine and a 5—speed manual transmission. A 1981 model—year vehicle was used for testing because Redline was able to procure it easily and the 1981 emission control system is identical to the 1982 system. It would be expected that vehicles of the previous model—years and the 1982 model—year would have the same degree of performance/emissions impact as the vehicle tested when using the same Redline kit. First, comparative exhaust emission tests were performed to determine the effects of the carburetor conversion and the disconnections associated with it, except for the disconnection of the aititude compensator. When the Weber carburetor was installed on the test vehicle the throttle opener control system, fuel shut—off vacuum switch, mixture ratio control vaive and altitude compensator were disconnected. The applicant performed testing at Import Certification Laboratories of Anaheim, California. The data submitted by Redline are shown in Table 1.

These results show no increase in emissions, however, when confirmatory testing was performed at the Haagen—Smit Laboratory, significant increases in both HC and CO were recorded. These results are shown in Table 2. Table 2 Exhaust Emissions gm/mi Fuel Economy Test Procedure CVS—75 Condition HC CO NOx City mi/gal BaseTine 0.400 14.770 0.520 25.3 0.448 15.274 0.518 25.0 Average 0.424 15.022 0.519 25.2 Redline Kit 0.586 37.122 0.458 23.5 0.638 38.560 0.430 23.4 Average 0.612 37.841 0.444 23.4 Therefore, the vehicle was returned to Redline with notice of the failure. Redline determined that the vacuum hose routing was improper when the vehicle was tested at the Haagen—Smit Laboratory. They corrected the problem and tested the vehicle at ICL again. The results of this test are shown in Table 3. Table 3 Exhaust Emissions gm/mi Fuel Economy Test Procedure CVS—75 Condition HC CO NOx City mi/gal Redline Kit 0.322 2.891 0.42 26.354 These results show no increase over the baseline values established by the confirmatory tests at the Haagen—Smit Laboratory. Redline was granted a retest of the Weber carburetor at the Haagen—Smit Laboratory and the results of these tests are shown in Table 4. The baseline values are also shown in this table for comparison.

The Ist series was run with the secondary air and a 2nd series without. Based on the measured concentrations of exhaust emissions and using the carbon balance method, the TAFR‘s under each steady—state test condition were calculated. According to equation 1 of MAC 78—2, Section II, the TAFR at an altitude of 6000 ft is: TAFR 909 = 49 * 9+84Mey s M 4 0.84m., 1.09mf° 1.09mfo 1.09mf0 Where m;, = mass flowrate of intake air at sea level mep = mass flowrate of secondary air at sea level meqp = mass flowrate of fuel at sea level Therefore Mio . TAFR, due to intake air Eq 50 = TAFRo due to secondary air "fo By calculating the TAFRO's of the vehicle with secondary air and without, the TAFRO due to secondary air can be calculated by subtracting the TAFR0 without secondary air from the TAFRo with secondary air, or: TAFRo (with secondary air) — TAFRO(without secondary air) = TAFRo(due to secondary air).

This allows the original q\ tion to be written in this form: TAFR6000 = TAFR0 (without secondary air) + (0.84)TAFR0 (due to secondary air) 1.09 1.09 Inserting the calculated TAFRO values into the above equation, the resulting TAFRs at 6000 feet are shown in Table 5. Table 5 Tailpipe Air/Fuel Ratios (TAFR) Stoichiometric Air/Fuel Ratio of Test Fuel = 14.6 Mode TAFR at Sea Level TAFR at 6000 feet Idle 16.7 14.9 30 mph 3rd gear 16.5 14.9 30 mph 4th gear 19.6 17.4 50 mph 4th gear 16.7 15.0 50 mph 5th gear 17.1 15.4 These results show that in all driving modes tested, the TAFR at 6000 feet is leaner than stoichiometric. VI. DISCUSSION The results of the final tests performed on the Datsun test vehicle show no increase in HC or CO and only a slight increase in NOx which is considered to be within the limits of test variability as determined by the Haagen—Smit Laboratory. The re;u]ts of the special test program and analysis demonstrate the ability of the Weber carburetor to comply with the California High Altitude Test Requirements. This demonstrates that while the installation of the Weber DGAV carburetor requires the disconnection of several emission control components no adverse emissions impact occurs. Redline has fulfilled the requirements for this exemption, therefore, the staff recommends that Executive Order D—133—108B be issued.
