                                    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 Kit No. K8205 using one (1)}) Weber model
32/36 DGAV 33B1 carburetor.

      The Redline Carburetor Conversion Kit replaces the original equipment

Solex 32/35 DIDTA carburetor as found on 1972—76 model—year BMW 2002 vehicles.

      Comparative exhaust emission tests demonstrate that the aftermarket

Redline Carburetor Conversion Kit No. K8205 using one Weber model 32/36 DGAY

33B1 carburetor does not adversely affect emissions.   Based on the results of

the tests and the evaluation of the Redline Carburetor Conversion Kit, the

staff recommends that the exemption be granted as requested for the 1972—76

model—year BMW 2002 vehicles equipped with a Solex 32/35 DIDTA carburetor.

EVALUATION OF THE REDLINE CARBURETOR CONVERSION KIT NO. K8205 USING MODEL
32/36 DGAV 33B1 WEBER CARBURETOR FOR EXEMPTION FROM THE PROHIBITIONS OF
VEKHICLE 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. K8205 utilizing one (1) Weber model 32/36 DGAYV 33B1

carburetor.    The Carburetor Conversion Kit is designed to replace the original

equipment manufacturer (OEM) Solex 32/35 DIDTA carburetor as found on

1972—1976 model—year BMW 2002 vehicles .

       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. K8205 using one (1) Weber

model 32/36 DGAV 33B1 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 emission data and the confirmatory

testing performed by the ARB 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.

K8205 using one (1) model 32/36 DGAV 33B1 Weber carburetor for 1972—1976

model—year BMW 2002 vehicles and that Executive Order No. D—133—6 be issued.


IV.   DEVICE DESCRIPTION

      The Redline Carburetor Conversion Kit No. K8205 uses one {1) Weber model

32/36 DGAV 33B1 carburetor to replace the OEM Solex 32/35 DIOTA carburetor

found on 1972—1976 BMW 2002 vehicles.

      The Solex 32/35 DIDTA (Solex) is a progressive two—barrel downdraft

carburetor.     The special features of this carburetor are a vacuum operated

secondary, a timed vacuum retard port, a thermo—starter valve and an

electrically assisted, engine coolant temperature controlled choke {see

Appendix 1)}.    Not all of these features are employed for the earlier

model—year vehicles.        The 1973—1976 BMW 2002 vehicles also utilize a throttle

positioner (dashpot) to control emissions during deceleration.

              The Weber 32/36 DGAV 3381    (Weber) is a progressive two—barrel

downdraft carburetor which is similar in basic design to the Solex carburetor

(see Appendix 2).     The Weber utilizes a mechanically operated secondary which

begins to open when the primary throttle is open approximately 70 percent.

The Weber does not have a timed vacuum retard port to operate the distributor

vacuum retard.     Because of this, the distributor vacuum retard is connected to

manifold vacuum when the Weber is installed.       The Weber does not use a thermo—

starter valve so this device is removed along with the Solex carburetor.         The

Weber utilizes a engine coolant temperature controlled choke only and does not

employ an electric assist.       The throttle positioner (dashpot) system is not

utilized with the Weber and is removed along with the OEM carburetor.

Therefore, when the Redline kit No. K8205 is installed, the following

modifications to the OEM exhaust emission control system are required:

      1       The throttle positioner (dashpot) system, on vehicles so equipped,

              is removed.

      2)      The electric assist choke, on vehicles so equipped, is disconnected.


                                          1 op L


      3)   The thermo—starter valve, on vehicles so equipped, is removed along

           with the original carburetor.

      4)   Vacuum hose routing is changed as specified in the device

           installation instructions.

      All other OEM emission control devices are retained.     The calibration of

the Weber DGAY 33B1 carburetor used in kit No. K8205 is shown in Appendix 3.

      The Redline kit No. K8205 comes complete with a Weber DGAV 33B1

carburetor, an air cleaner adaptor, installation instructions (see Appendix 4)

and all the gaskets and hardware necessary to properly install the Weber

carburetor on the BMW 2002 vehicles.

      The facsimile of the identification label displays the required

information and is shown in Appendix 5.

V.    DEVICE EVALUATION

      The applicant performed comparative cold—start CVS—75 exhaust emission

tests at Import Certification Laboratories (ICL) in Anahem, California.        A

1975 BMW 2002 equipped with a 2.0 liter engine and a 4—speed manual

transmission was used as the test vehicle.   The 1975 model—year vehicle was

accepted as the test vehicle since the 1975 model—year emission control system

is identical to the 1976 model—year emission control system.     It would be

expected that vehicles of previous model—years and the 1976 model—year, would

have the same degree of performance/emissions impact as the vehicle tested

when using the same Redline Kit.   The submitted data showed decreases in all

three pollutants from the baseline levels.   Confirmatory testing was performed

at the Haagen—Smit Laboratory, on the same vehicle, and the results


showed a significant increase in NOx emissions.     Redline investigated the

cause of the NOx problem and determined that the exhaust gas recirculation

(ESR) system was malfunctioning.     To solve the problem, the EGR filter, which

was dirty, and the EGR inlet tube, which was leaking slightly, were replaced.

To verify that these parts were responsible for the high NOx values, Redline

again performed comparative cold—start CVS—75 exhaust emission tests at ICL.

The results of these tests are shown in Table 1.


                                      Table 1

*Average of two tests in each condition.


      Confirmatory testing was again performed at the Haagen—Smit Laboratory,

on the same vehicle and the results of these tests are shown in Table 2.

    Redline Kit          0.89        10.28           1.01            14.3



*Average of two tests in each configuration.


VI.   DISCUSSION

      The results of the emissions testing show that the HC emissions of the

test vehicle are slightly lower and its CO/NOx emissions remain unchanged from

the baseline values.   The differences in CO/NOx values between the baseline

and the Redline kit test are considered to be within the limits of test

variability as determined by the Haagen—Smit Laboratory.

      This demonstrates that the installation of the Weber carburetor and the

modifications to the original exhaust emission control system required for the

installation will not have an adverse effect on emissions from the 1972—1976

BMW 2002 vehicles.

      The results of the emissions tests performed after the EGR system was

repaired show decreases in NOx emissions for both baseline and device

conditions.   This demonstrates that the parts which were replaced were most

likely responsible for the NOx control problem.

      Redline has submitted all the required information and fulfilled the

requirements for an exemption.
