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.

                                    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.

    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.

    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.

      With the test vehicle in the device configuration {altitude compensator

disconnected) a series of steady—state exhaust emission tests were performed

at the Haagen~—Smit Laboratory.    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

      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)

      Inserting the calculated TAFRO values into the above equation, the

resulting TAFRs at 6000 feet are shown in Table 5.

            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.
