                                     SUMMARY



      Redline, Inc., a distributor of ltalian made Weber carburetors, has

applied for exemption from the prohibitions of Vehicle Code Section 27156 for

their Redline kit numbers K8746, K8747, K8748, and K8749 using Weber 32/36

DGAY 33B1 and 32/36 DGEY 33B1 carburetors.

      Comparative exhaust emission tests demonstrate that the aftermarket

Redline kits using Weber carburetor model 32/36 DGAV 33B1 or 32/36 DGEV 3381

do not adversely affect emissions.   Based on the results of the tests and the

Board‘s evaluation of the Redline kits, the staff recommends that the

exemption be granted for the vehicles as requested.

EVALUATION OF THE MODEL 32/36 DGAY 33B1 AND 32/36 DGEV 33B1 WEBER CARBURETORS
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 Torrance, California, a subsidiary of Imported Parts

and Accessories Corporation {IMPAC), is a distributor of Italian—made Weber
carburetors and has applied for exemption from the prohibitions of Vehicle

Code Section 27156 for aftermarket carburetor kits designated as the kit

numbers K8746, K8747, K8748 and K8749 using Weber 32/36 DGAV 33B1 and 32/36

DGEY 33B1 carburetors.   Exemption is sought as an exchange carburetor for the

original equipment Aisan 21100 carburetor as found on limited 1975—1984 Toyota

vehicles equipped with the 20R and 22R engines.

      This report describes the evaluation of the Redline kits using Weber

32/36 DGAV 33B1 and 32/36 DGEY 33B1 carburetors and the findings.

I1.   CONCLUSIONS

      Comparative exhaust emission data submitted by the applicant demonstrated

that the Weber model 32/36 DGAV 33B1 and 32/36 DGEV 33B1 carburetors have

similar emission characteristics as that of an Aisan 21100 carburetor.      The

applicant also submitted carburetor flow curves, and EGR and spark advance

signal curves of the model 32/36 DGEV 33B1 to demonstrate that the Weber

aftermarket carburetor functions in a like manner as to similar Aisan

counterparts.   Weber 32/36 DGAV 33B1 and 32/36 DGEY 33B] carburetors simply

exchange the existing carburetor with only linkage and adaptor modifications

and the stock air cleaner housing is retained.     The idle mixture screw has a

limiting adjustment cap to prevent tampering.     Confirmatory testing at the ARB

Haagen~—Smit Laboratory indicated reduced hydrocarbon and carbon monoxide

emissions and only a slight increase (0.05 gm/mi) in oxides of nitrogen.


111.         RECOMMENDATIONS

         Based on the submitted comparative data of the Weber carburetors, the

staff recommends that Redline, Inc. be granted exemption from the prohibitions

of Vehicle Code Section 27156 for the Weber aftermarket carburetor models

32/36 DGAVYV 33B1 and 32/36 DGEV 33B1 for the years, make, and models of

vehicles listed below:

IV.      DEVICE DESCRIPTION

         Both the Weber 32/36 DGAV 33B1 and 32/36 DGEV 33B1 (32/36 DGAV/EY 33B1)

and Aisan 21100 carburetors are progressive two—barrel down draft designs.

Appendix A shows typical views of the Aisan and Weber carburetors.                The main

differences between the carburetors are the manner in which the secondary

throttle is activated, jet sizes, and certain ancillary features.                The Weber

carburetors use a manually—operated secondary which starts to open after a

primary throttle opens aeg:zs{zfte1y 68 percent.             The Aisan carburetor uses a

vacuum operated secondany(Ftarts to open after 50° of primary throttle

opening.        The secondary fuel cut system and the auxiliary accelerator pump

features of the Aisan carburetors are not utilized in the Weber.                The Weber

carburetor uses an internal choke pull down rather than the external system of

the Aisan.

        The DGAY carburetor utilizes engine coolant to activate the choke and

the DGEV carburetor choke is electrically activated.                Page A—2 of Appendix A

indicates the differences in choke actuation mechanism.                Part numbers 45—48


show the choke used on the DGAY carburetor and part number 99 is used on the

DGEY carburetor.        The Redline kits use electrically actuated chokes for

vehicles in which the original equipment choke is electrically actuated (on

later model—year Toyotas) and coolant actuated chokes for vehicles in which

the original equipment choke is coolant actuated (on older model—year

Toyotas}.        With the exceptions noted in Table 1 and the choke actuation

mechanism, the carburetors are identical for all vehicles for which the
Vehicle Code Section 27156 exemption is requested.

            Three Weber carburetor configurations are used in the four kits utiized

to cover the vehicles for which exemption was requested.            Each kit contains

appropriate linkage, and carburetor and air cleaner adaptors.             Internal

carburetor differences are given in Table 1.

V.          EVALUATION PROGRAM

            The applicant performed comparative CVS—~—75 exhaust emission tests at

Import Certification Laboratories in Anaheim, California.           A 1982 Toyota
Celica equipped with a 22R (2366 cc) engine and automatic transmission, and a


1983 Toyota 4X4 pick—up truck equipped with a 22R (2366 cc) engine and manual

5—speed transmission, were used for the tests.

      During the evaluation, testing was performed onlllrepresentative

production carburetors to show that the exhaust emission levels would not be

adversely affected by the use of the Weber 32/36 DGEV 33B1 carburetor.

Baseline tests with the Aisan carburetors were performed to show that the

stock vehicles were in proper working order and that emissions of the vehicle

were within the applicable state standards.

      The comparative exhaust emission and derived fuel economy data are given

in Table 2.

VI.      DISCUSSION

         The applicant‘s submitted comparative emission and bench test data is

generally acceptable.     The submitted emission test data showed no significant

increase in emissions.     The ARB confirmatory tests indicated no significant

increase in emissions.     Although there are some differences in the operation

of the Aisan and Weber carburetors, as described in Section IV of this report,

the Weber 32/36 DGEV 33B1 does not adversely affect exhaust emissions.

         The two 1982 and 1983 model—year vehiclies selected for testing use the

electrically actuated choke.        There were no significant emission differences

between the baseline and Redline kit tests for carburetors using the electric

choke.     No testing was conducted on vehicles using the coolant actuated

choke.     Redline kit chokes are designed to have similar choke opening times as

the original equipment chokes.       Therefore, it is to be expected that the

Redline kits with coolant actuated choke systems will exhibit similar emission

characteristics as the original equipment Aisan carburetors with hydraulic

choke systems and will have no significant effect on emissions.

         Driveability was not evaluated during the testing of the Weber 32/36
DGAV/EV 33B1 carburetors.     However, if driveability was adversely impaired,

emissions would have more than likely increased.


      Although the test data of the Weber 32/36 DGEV 33B1 carburetors reveals

them to be functionally similar with regard to emissions to the later models

of the Aisan carburetors, they cannot be classified as an Aftermarket

Replacement Part as differences are found in the bench air flow data, emission

controls vacuum signals, and the carburetor choke and power circuits.

      The Weber 32/36 DGAY 33B1 and 32/36 DGEV 33B1 carburetors are packaged

in four separate kits identified as kits K8746, K8747, K8748, and K8749.   The

same carburetor is used in each kit except the connective throttle

arrangements differ to facilitate various configurations found on the vehicle

models, and various jet and choke parameters vary among the carburetors.

 All tune—up specifications for the Weber Carburetor remain the same as those specified by the Factory for the
 original unit. Emissions tune—up should be carried out by a suitably qualified Dealer or Independent garage,
 using infrared gas analyzing equipment.

 NOTE: Late model vehicles fitted with Emission Control Systems have many vacuum lines and electrical
 connections in their fuel systems. it is essential when dismantling, that disconnected lines be identified with a
 number tag or label system. To establish function, locate and identify the source of each line.

  NOTE: it is imperative that you familiarize yourself with the glossary of abbreviations and the schematics of
  vacuum lines and emissions control components included with these instructions BEFORE you begin the
~ installation.
