                                   sumary

      Carter Automotive Division (CAD) requested an update to the existing Air

Resources Board‘s Executive Order No. D—137.   Request made is to include the

vehicles equipped with a closed—loop (computer controlled) carburetion system

in the exemption of the "Engine Knock Eliminator" (EKE) add—on device.
      CAD has submitted data of comparative cold—start CVS—75 emission test

data generated from a 1984 Chevrolet Chevette powered by a 1.6 lTiter engine

using closed—loop carburetion system.

      Based on the comparative exhaust emission tests performed on the late

model vehicle, the staff concludes that the EKE will not have an adverse

effect on exhaust emission from vehicles equipped with closed—1loop carburetion

system.
      The staff recommends that CAD be granted an updated exemption from the

prohibitions in Vehicle Code Section 27156 for their EKE device for

installation on 1984 and older model—year gasoline—powered motor vehicles,

excluding the following:

           1.   General Motors Corporation vehicles with an "odd—firing" V6

                231 CID engine;

           2.    Vehicles powered by a rotary engine; and

           3.    Vehicles equipped with more than one ignition coil.

EVALUATION OF CARTER AUTOMOTIVE DIVISION‘S "ENGINE KNOCK ELIMINATOR®" FOR
EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE
WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE.


I.     INTRODUCTION

       Carter Automotive Division (CAD) of ACF Industries, Incorporated, 9666

Olive Boulevard, St. Louis, Missouri 63132, requested an update to the

existing Air Resources Board‘s Executive Order (E.0.) No. D—137.    Request made

is to include the vehicles equipped with a closed—loop (computer controlled)

carburetion system in the exemption of the "Engine Knock Eliminator" (EKE)

add—on device.
       CAD has submitted data of comparative cold—start CVS—75 emission test

data generated from a 1984 Chevrolet Chevette powered by a 1.6 liter engine

using closed=l]oop carburetion system.   Tests were performed under contract by

the Olson Engineering, Inc. laboratory in Huntington Beach, California.

II.    CONCLUSION

       Based on the comparative exhaust emission tests performed on the late

model vehicle, the staff concludes that the EKE will not have an adverse

effect on exhaust emission from vehicles equipped with closed—loop carburetion

system.
III.   RECOMMENDATIONS

       'Based on the above conclusion, the staff recommends that CAD be granted

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

their EKE device.     Update is to include the vehicles equipped with a

closed—loop carburetion system.

       The staff also recommends that Executive Order No. D—137—1 be issued,

exempting the EKE device for installation on 1984 and older model—year
gasoline—powered motor vehicles, excluding the following:


           1.      General Motors Corporation vehicles with an "odd—firing" V6

                   231 CID engine;

           2.      Vehicles powered by a rotary engine; and

           3.      Vehicles equipped with more than one ignition coil.

IV.   DEVICE DESCRIPTION AND OPERATION

      The EKE is an add—on device which senses engine detonation and

electronically retards ignition timing to eliminate detonation.     The major

components of the EKE are a detonation sensor and an electronic control unit.

The components are packaged with installation hardware and instructions and

sold as a kit.

      The detonation sensor has a 3/8" standard threaded stud designed to be

bolited directly to any existing vacant 3/8"—16 threaded hole in the intake

manifold or cylinder head where there is no interference with throttle or

choke mechanism.     The sensor senses engine vibratton and generates an

electrical signal to the electronic control unit.     The knock sensor consists

of an amplifier and a discriminator.     The amplifier amplifies the intensity of

the vibration for signal generation; whereas, the discriminator will discrete

engine noise/vibration interference from engine detonation, thus, generating a

volitage signal only under engine detonation conditions.

      The electronic control unit is a transistorized module which interprets

voltage signals from the knock sensor (during detonation} to retard ignition

timing until detonation is eTiminated.     Once detonation is ceased, the

ignition timing is slowly returned to OEM specification.      The amount of retard ¥——
is proportional to the strength and frequency of the engine knock.       Although

the maximum retard is about 15 degrees, the actual amount of retard is only

enough to eliminate engine knock.     CAD technicians claim that the retard


control response (time required to retard timing by 15 degrees) is 0.5
seconds, and advance control response (time required to forward ignition

timing to OEM specification, up to 15 degrees) is 3.8 seconds.   Ignition
retardation is accomplished through the control unit by delaying the

termination of current to the ignition coil and, thus, the ignition timing.

      The control unit contains a four—, six—, and eight—cylinder rotating

selector to accommodate all engine sizes.

V.    EVALUATION

      CAD submitted data of comparative (without and with the device installed

on a test vehicle) cold—start CVS—75 emission tests.   The tests were performed

on a 1984 Chevrolet Chevette powered by a 1.6 liter engine using a closed—loop

carburetion system.   A summary of the test results is shown in the Appendix.

VI.   DISCUSSION

      CAD‘s comparative data (shown in the Appendix) indicate that their EKE

device did not have an adverse effect on exhaust emissions from the vehicle

tested.
