SUMMARY Redline, Inc., a distributor of Italian made Weber carburetors, has applied for exemption from the prohibitions of Vehicle Code Section 27156 for the RedlTine Carburetor Conversion Kit No. K8622 using one (1) Weber model 32/32 DGAV 5E carburetor. This Redline Carburetor Convers1on K1tisdes1gned to replace the Hitachi carburetors found on 1970—1974 Datsun 1200 and B210 model vehicles. Comparisons of the OEM Hitachi carburetor to the Weber carburetor, with respect to calibration, vacuum port signals and choke operation demonstrate that the Weber carburetor functions similarly but not identically to the Hitacht carburetor. Therefore, the Weber 32/32 DGAV 5E carburetor cannot be classified as a replacement part for the 1970—1974 Datsun 1200 and B210 model vehicles and must receive an exemption to be legally marketed in California. Based on the submitted comparisons and an engineering evaluation, the staff concludes that the installation of the Redline Kit No. K8622 will not have an adverse emissions effect and recommends that an exemption be granted for the following vehicle applications: Vehicle Model Redline Weber Year(s) Make or Engine Type Kit No. Carb. Model No. 1970—1974 Datsun 1200 and B210 K8622 32/32 DGAV 5E

EVALUATION OF THE REDLINE CARBURETOR CONVERSION KIT NO. K8622 FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE 1. INTRODUCTION Redline, Inc., of Compton, California, a subsidiary of Imported Parts and Accessories Corporation {(IMPAC), is a distributor of Italian made Weber _carburetors.Thecompanyhasappliedforexemptionfromtheprohibitions—of——————— Vehicle Code Section 27156 for a Carburetor Conversion Kit designated as Redline Kit No. K8622 using a Weber carburetor to replace the original equipment manufacturer (OEM) Hitachi two—barrel carburetors found on the following vehicles: Vehicle Model Redline Weber Year(s) Make or Engine Type Kit No. Carb. Model No. 1970—1974 Datsun 1200 and B210 K8622 32/32 DGAV 5E This report describes the evaluation of the Redline Carburetor Conversion Kit and the findings. II. CONCLUSION Based on the submitted comparisons, and an engineering evaluation, the staff concludes that the installation of the Redline Kit No. K8622 will not have an adverse emissions effect on the vehicles described above. III. RECOMMENDATION The staff recommends that this exemption be granted on an engineering evaluation and that Executive Order D—133—14 be issued. IV. DEVICE DESCRIPTION The Redline Carburetor Conversion Kit No. K8622 uses one (1) model 32/32 DGAV 5E Weber carburetor as an economical replacement for the OEM carburetors found on the 1970—1974 Datsun vehicles described previously. en

These Datsun vehicles are equipped with a Hitachi carburetor. These Hitachi carburetors are of the progressive two—barrel design (See Appendix 1). The Weber 32/32 DGAY 5E 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 distrisutor vacuum advance/retard units, EGR and air 1nJect1on contro]systems A variety of emission contro] dev1ces 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 actiQated 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 differeht manner, however, some devices cannot be retained. These devices and their disposition after the intallation of the Weber carburetor are: 1) The Throttle Positioner or Dashpot, on vehicles so equipped, is disconnected and removed. 2) The Altitude Corrector, on vehicles so equipped, is disconnected and removed. 3) The Vacuum Hose Routing is changed as specified in the kit installation instructions. All other original equipment emission control devices are retained. The installation instructions recommend that the vehicles must be tuned to the vehicle manufacturer‘s specifications. The Redline Kits come complete with a Weber carburetor, an air c]eanér adaptor, all the hoses, gaskets and hardware necessary to install the Weber cakburetor on the Datsun vehicles. Instaliation instructions, which are included in every kit, show the kit installer how to properly install the Weber carburetor (see Appendix 3). A sample identification label is shown in ,205°% Appendix 4. The Weber carburetor calibrations are included in Appendix 5.

L095is, V. DEVICE EVALUATION The evaluation of the Redline kit no. K8622 consisted of an analysis of the submitted data, a study of the emission control systems used on the 1970—1974 Datsun 1200 and B210 model1 vehicles and emissions tests performed on a 1981 Datsun 210 station wagon . Redline submitted an emissions system evalu ation which shows which OEM systems can be reconnected to the Weber carbu retor and function nearly the same and which systems must be disconnected. To demonstrate the Weber carburetor was compatible with the vacuum actuated emission control devices used on the Datsun vehicles, Redline submitted carburetor flow bench data which compares the vacuum signal strength between the OEM Hitachi and the Weber for the vacuum advance diaphragm and the EGR vaive ({see Appendix 6). Graph A—6.1 shows the dry flow bench depre ssion of the OEM Hitachi carburetor for a 1974 Datsun B210 (Hitachi) and the Weber 32/32 DGAV 5E (Weber) versus the throttle opening in degrees. This shows the effect of the larger throt tle plate diameter of the Weber which allows the same flow bench depression with less throttle opening. This difference means that the Weber throttlie must be opened less to achieve the same power levels, during normal driving, or a FTP driving cycle this would not have an emiss ions effect. Graph A—6.2 shows the vacuum signal strength versus spark advan ce in crankshaft degrees. From this it can be seen that the only area of interest on Graph A—6.3 is between 10.5 and 22.5 cm. Hg. On the left end of graph A—6.3 (throttle openings below 10°) the two carburetors produce nearly the same spark advance signal. At the right end of the same graph (throttle openings above 50°) the Weber signal drops off sooner than the Hitachi but, at nearly the same rate. The effect of this should retard the spark advance slig htly as compared to the stock spark coxten,

advance at the same throttle setting and shoul d theoretically slightly reduce emissions. Any differences in the two vacuu m signal strength curves outside of the area of interest are irrelevant. Graph A—6.4 shows the vacuum signal strength versus EGR valve opening. From this it can be seen that the only area of interest on Graph A—6.5 is between 6 and 10.5 cm. Hg. The Weber signa l comes on about 10° later than the Hitachi. This should slightly improve driv ability while having a minimal effect on emissions. Any differences in the two vacuum signal strength curves outside of the area of interest are irrel evant. Also submitted was a | comparison of the automatic choke opera tion between the two carburetors which shows that they function nearly the same. A study of the emission control systems shows that the 1970—1973 Datsun 1200 vehicles have only one emission contr ol component which is not compatible with the Weber carburetor. It is the throttle positioner, a device used to open the throttle plate slightly to contr ol hydrocarbon emissions during deceleration. On these Datsun vehicles an altitude corrector is used in the throttle positioner syStem. Since the throttle positioner is removed, this altitude corrector serves no function and is also removed. Redline has previously demonstrated that the Weber DGAYV series carburetors do not need an external devic e to control hydrocarbons on deceleration by performing emissions tests used for the evaluation of other Redline kits which required the removal of a similar throttle positioner device (see staff reports accompanying E.0. No‘s. D—133—6, D—133—7, D—133—10A, D—133—10B, D—133—12 and D—133—13). The 1974 B210 models utilize the same throttle positioner system and in addition, a dashpot on the automatic transmission models. The purpose of the

dashpot is to prevent the engine from stalling during hard braking with the transmission in gear. Stalling does not occur with the Weber carburetor on these models therefore the device is removed. Emissions test performed on a 1981 Datsun 210 station wagon demonstrated that the installation of the Weber DGAV carbu retor and the disconnections associated with it (which include more items than disconnected on the 1970—1974 vehicles) does not have an adverse emissions effect. For details of this evaluation and the actual test results please refer to the August, 1986, staff report entitled "EVALUATION OF THE REDLINE CARBURETOR CONVERSION KIT No. K8625 FOR EXEMPTION FROM THE PROKHIBITIONS oFr VEHIC LE CODE SECTION 27156 IN _ ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE copE." VI. DISCUSSION The staff evaluation of the Redline carburetor conversion kit K8622 revealed the following: 1. The Weber carburetor vacuum signal strength curve for vacuum advance and EGR are nearly the same as OEM. 2. It has been previously demonstrated that the disconnection of the throttle positioner when the Weber carbu retor is installed does not cause an adverse emissions effect. 3. The emissions tests performed on a 1981 Datsu n 210 station wagon showed no significant increase in emissions with the Weber carburetor installed. 4. The vehicles for which this carburetor kit is applicable to are at least 13 years old.

Based on the abqve points the staff has determined that the Redline K8622 kit cannot be classified as a replacemen t part but should be granted an exemption based on this engineering evaluation which has determined that the Weber carburetor will function nearly the same as OEM and therefore will not have an adverse effect on emissions. The staff recommends that an exemption be granted and that Executive Order D—133—14 be issued.
