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 Conversion Kits No. K8651 and No. K8655 using.one (1) Weber model 32/34 DFT9 A or 32/34 DFTII A carburetor. These Redline Carburetor Conversion Kits are designed to replace the — Hitachi carburetors found on 1968—1973 Datsun 510 and 1970—1972 Datsun pick—up trucks with 1.6 liter engines. Redine has previously demonstrated that the Weber 32/34 DFT9 A and 32/34 DFTII A carburetors do not cause an increase in emissions when used to replace the original equipment manufacturer (OEM) Hitachi carburetors found on 1972—1980 Datsun vehicles with 1.8 and 2.0 liter engines. Executive Orders D—133 and D—133—1 were issued granting Redline exemptions for those Datsun vehicles. The Datsun 1.6, 1.8 and 2.0 liter engines are of the same design and utilize very similar systems for emission control. The 1.6 liter engines found in the early model 510 and pick—up trucks utilize the most simple emission control systems of all these Datsun vehicles. Becausebof the previous demonstration of the Weber‘s ability to perform, with respect to emissions, on newer model—year Datsun vehicles with engines of the same design and with more complex emission control systems, the staff recommends that the exemption be granted as requested for the following vehicle applications: Year Make Mode? Engine (liter, CID} Redline Kit. No. 1968—1973 Datsun .« 510 1.6, 98 K8651 1970—1972 Datsun Pick—up (521) 1.6, 98 K8655

EVALUATION OF THE REDLINE CARBURETOR CONVERSION KITS NO. K8651 AND NO. K8655 USING ONE (1) MODEL 32/34 DFT9 A OR 32/34 DFT11 A WEBER CARBURETOR FOR EXEMPTION FROM THE PROKIBITIONS OF VEKICLE 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 two Carburetor Conversion Kits designated as Redline Kits No. K8651 and No. K8655 using one (1) Weber model 32/34 DFT9 A or 32/34 DFTII A carburetor to replace the original equipment manufacturer (OEM) Hitachi two—barrel carburetors found on the following vehicles: Year Make Model Engine (liter, CID) Redline Kit No. 1968—1973 Datsun 510 1.6, 98 K8651 1970—1972 Datsun Pick—up (§21) 1.6, 98 K8655 This report describes the evaluation of the Redline Carburetor Conversion Kits and the findings. II. CONCLUSION Based on a previous demonstration that the Weber 32/34 DFT9 A and 32/34 DFTI1 A do not cause an increase in emissions when used to replace the OEM carburetors on later model—year Datsun vehicles with more complex emission control systems, the staff concludes that the installation of the Weber 32/34 DFT9 A or 32/34 DFTIHI A carburetor will not have an adverse effect on emissions when installed on the vehicles described above.

III. RECOMMENDATION The staff recommends that Redline, Inc. be granted exemption from the prohibitions of Vehicle Code Section 27156 for the Redline Carburetor Conversion Kits No. K8651 and No. K8655 for use on the vehicles described above and that Executive Order No. D—133—11 be issued. IV. DEVICE DESCRIPTION The Redline Carburetor Conversion Kits No. K8651 and No. K8655 are similar in design. Each kit uses one (1) model 32/34 DFT9 A or 32/34 DFTIl A Weber carburetor as an economical replacement for the OEM carburetors found on the 1968—1973 Datsun 510 passenger cars and pick—up trucks described previously. The model 32/34 DFT9 A (9 A) and model 32/34 DFTII A (11 A) Weber carburetors have the same calibration and can be used interchangeably. The only difference between the two models is that the 9 A is built in the Weber factory with an EGR port and the 11 A is not. For applications which require an EGR port the 9 A can be used "as is" and an EGR port can be added to the 11 A by Redline, at their facility, making the two models equivalent. For applications which do not require an EGR port the 11 A can be used "as is" and the EGR port on the 9 A can be plugged. The Datsun 510 passenger cars and pick—up trucks described previously are equipped with a Hitachi carburetor. The Hitachi carburetor is of the progressive two—barrel design (See Appendix 1). The Weber 32/34 DFT is a progressive two—barrel carburetor which is similar in basic design to the OEM carburetors (See Appendix 2). The Weber 32/34 DFT is a slightly different version of the Weber DFT (Ford 740) carburetors used as original equipment on some Ford imports orignally sold in California. 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 installation of the Weber carburetor are: 1} The Boost Controlled Deceleration Device (BCDD), on vehicles so equipped, is disconnected and removed. 2) The deceleration control valve (Coasting Richer valve) on veicles so equipped, is disconnected and removed. 3) On pick—up models, the throttle switch mounted on the carburetor is disconnected and removed along with the original carburetor. The Redline Kits No. K8651 and No. K8655 come complete with a Weber DFT carburetor, an air cleaner adaptor and all the hoses, gaskets and hardware necessary to install the Weber carburetor on the Datsun 510 or pick—up vehicles. Installation instructions, which are included in every kit, show the kit installer how to properly install the Weber carburetor. Vacuum port diagrams, contained in the instructions, show the proper vacuum hose connections to the Weber carburetor (see Appendix 3). Facsimilies of the identification labels are shown in Appendix 4.

V. DEVICE EVALUATION The evaluation of the Redline carburetor conversion kits K8651 and K§655 is based on an engineering evaluation and comparative exhaust emissions testing performed previously on similar Datsun vehicles during the evaluation of similar Redline kits which led to the issue of Executive Orders D—133 and D—133—1. Two of the disconnections associated with kits K86§51 and K8655, the coasting richer valve and the BCDD are very similar. The coasting richer valve is used on 1970 and 1971 Datsun vehicles and BCDD is used on 1972 and later Datsun vehicles for the control of hydrocarbon emissions during deceleration. The coasting richer valve is an electrically activated solenoid which allows additional air—fuel mixture to by—pass the throttle plate of the carburetor during deceleration which provides enough mixture to the engine to maintain combustion thereby reducing hydrocarbon emissions. It is activated through a series of switches which can detect a decelerating condition. The BCDD performs the same by—passing function, but, it is activated by high intake manifold vacuum which occurs during deceleration. The disconnection of the BCDD was evaluated on two Datsun test vehicles; a 1976 Datsun 710 and a 1980 Datsun Pick-up. Both of these test vehicles had their BCDD device disconnected when the Weber carburetor was installed. The results of the comparative exhaust emissions tests performed at Import Certification Laboratories of Anaheim, California, are shown in Table 1 and Table 2.

Table 1 Test Results: 1976 Datsun 710 Test Procedure: Back—To—Back CVS—75 Exhaust Emissions gm/mi Fuel Economy mi/gal Condition HC cCO NOx City Baseline 0.8 4.6 2.2 18.8 Production Weber 0.9 4.8 1.8 19.4 Table 2 Test Results: 1980 Datsun Pick—Up Test Procedure: Back—To—Back CVS—75 Exhaust Emissions gm/mi Fuel Economy mi/ga] Condition HC CG NOx City Baseiine 0.2 4.1 1.1 22.0 Production Weber 0.2 2.7 1.0 22.2 The results of these tests show that while the installation of the Weber carburetor requires the removal of the BCDD no adverse emissions impact occurs. Because these tests demonstrated the ability of the Weber carburetor to control emissions during deceleration without the use of any external devices the staff has determined that the disconnection of the coasting richer valve will not cause an adverse emissions impact either. The only other disconnection required for the installation of kits K8651 and K8655 is the disconnection and removal of the throttle valve switch which is mounted on the original Hitachi carburetor used on the 1970—1972 Datsun Pick—ups only. The disconnection of this switch alters the function of the original equipment dual point distributor system. The function of this system is to retard the ignition timing, when the vehicle is under light load in third gear and warm. It does this via a second set of points which are seven crankshaft degrees out of phase in the retarded direction. The disconnection

of this switch prevents this retarding action from occuring under the proper conditions. The staff evaluated the CVS—75 test cycle and determined that the retarded points would only be activated nine percent of the entire test cycle on a bag weighted basis. Therefore, the staff has determined that the disconnection of this system would have little effect on emissions. It should be noted that Nissan dropped the use of the dual point distributor system in 1974 and later years and did not replace it with any equivalent system and were still able to meet certification requirements. VI. DISCUSSION The evaluation of the Redline carburetor conversion kits No. K86§51 and No. K8655 is based on an engineering evaluation. Kits No. K8651 and No. K8655 are very similar to Kits No. K8660, No. K8650, No. K8640, and No. K8666, which were previously exempted, with the significant differences being in throttle lTinkage. The engines used in the Datsun 510 and pick—up vehicles are of the same design as the engines used in the newer model—year Datsun vehicles for which exemptions have already been granted, with the significant differences being in displacement and the complexity of the emission control systems, with the Datsun 510 and pick—up vehicles being less complex. As shown by the comparative exhaust emission tests previously performed the disconnection of the BCDD or similar devices does not have a significantly adverse effect on emissions. The effect of removing the throttle vaive switch has been determined to be negligible. Therefore, the staff recommends that the requirement for comparative emissions tests on Kits No. K8651 and No. K8655 be substituted by this engineering evaluation and that Redline, Inc. be granted an exemption for these kits.
