This exemption shall not apply to any device, apparatus, or mechanism
advertised, offered for sale or sold with, or installed on, a motor vehicle
prior to or concurrent with transfer to an ultimate purchaser.

This Executive Order is valid provided that installation instructions for this
device will not recommend tuning the vehicle to specifications different from
those submitted by the device manufacturer.

Changes made to the design or operating conditions of the device, as exempted

                                     SUMMARY




         Allied Signal, Garrett Aftermarket Division (Garrett), has requested

an exemption from the prohibitions    in Vehicle Code Section 27156 for their

air—to—air   intercooier kits.   The kits are    intended for   installation on

1985—1987 2.4   liter Toyota trucks and 1987 2.0     liter Pontiac Grand AM

vehicles.

         Based on:   (1) previous comparative (turbocharged vehicle without

and with an air—to—air    intercooler kit) tests evaluating the exhaust

emission effects of previously exempt    intercooler klts; and (2) the staff‘s

engineering evaluation of the    intercooler‘s    impact on sxhaust emissions from

vehicles, the staff concludes that Garrett‘s air—to—air         intercooler kits

will   not adversely affect exhaust emissions from vehicles for which

exemption in requested.

         The staff recommends that Garrett be granted an exemption for their

intercooler kits as requested and that Executive Order D—173 be         issued.

EVALUATION OF ALLIED SIGNAL, GARRETT AFTERMARKET DIVISION‘S AIR—TO—AIR
INTERCOOLER KITS FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION
27156    IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA
ADMINISTRATIVE CODE


        1.    INTRODUCTION

             Allled Signal, Garrett Aftermarket Division (Garrett), of 2511

Edison Way, Compton, California 90220, has requested an exemption from the

prohibitions           in Vehicle Code Section 27156 for their air—to—air       intercooler

kits.        The kits are intended for        installation on 1985—1987 2.4 liter Toyota

trucks and 1987 2.0 liter Pontiac Grand AM vehicles.

    UP.        NCLUS    1 ON

             Based on:          (1) previous comparative (turbocharged vehicle without

and with an air—to—air              intercooler kit) tests evaluating the exhaust

emission effects of previously exempt                 intercooler kits; and (2) the staff‘s

engineering evaluation of the              intercooler‘s impact on exhaust emissions from

vehicles, the staff concludes that Garrett‘s air—to—air                 intercooler kits

will not adversely affect exhaust emissions from vehicles for which

exemption in requested.

   II 1. RECOMMENDATIONS

             The staff recommends that Garrett be granted an exemption for their

intercooler kits as requested and that Executive Order D—173 be                 issued.

    IV. INTER           LER KIT D       RIPTION AND    OPERATION

             The purpose of the intercooler is to reduce the temperature of the

Intake air/fue! charge going              into the turbocharged engine.    This rgduction

in the intake charge temperature allows a higher charge density (more amount

of air per minute flowing through the engine) which means more fue!                 into the

engine at a given              intake manifold vacuum/pressure.


        The major component of the Garrett alr—to—air        intercooler kit   is the

heat exchanger.     It   is packaged with   instaliation hardware and instructions

and sold as a kit.       The kit   is designed using different design concepts,

including tubing lengths, diameter and bends, to suit the requirements of

the individual vehicle.

        The air—to—air heat exchanger is located in such a way that the

heated charge air flow goes through one section and ambient air flows

through the other section, cooling the heated, compressed charge air.          The

cooled compressed air      is then passed out of the heat exchanger to the     intake

manifold.   The   location for the     installation of the heat exchanger varies

with each vehicle model! .

     v. pISCUSSION

        According to the performance analysis submitted by Garrett and of

other companies,   the staff have found that the thermal efficiency of an

intercooler kit ranges between 40% and 84% and that the reduction in the

combustion temperature, resulted from the cooler        intake charge due to the

installation of the Intercooler kit, will       reduce the formation of NOX gases

in the combustion chamber and, therefore, through the exhaust system.
