                                       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:

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.

      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.
