Section 43644 of the Health and Safety Code provides as follows: "43644. (a) No person shall instalil, sell, offer for sale, or advertise, or, except in an application to the state board for certification of a device, represent, any device as a motor vehicle pollution control device for use on any used motor vehicle unless that device has been certified by the state board. No person shall sell, offer for sale, advertise, or represent any motor vehicle pollution control device as a certified device which, in fact, is not a certified device. Any violation of this subdivision is a misdemeanor."

Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

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.
