State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—41 Relating to Exemptions under Section 27156 of the Vehicle Code GAS MIZER INCORPORATED "CAS MIZER" Pursuant to the authority vested in the Air Resources Board by Section 27156 of. the Vehicle Code; and Pursuant to the authority vested in the undersigned by Section 39023 of the Health and Safety Code; IT IS ORDERED AND RESOLVED: That the installation of the "Gas Mizer" device manufactured by Gas Mizer Incorporated, 8399 Topanga Canyon Blvd., Canoga Park, California 91304 has been found to not reduce the effective— ness of required motor vehicle pollution control devices and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1974 and older model—year vehicles except the following: > 1. All vehicles equipped with a breakerless or electronic ignition system. 2. All 1966—70 model—year vehicles equipped with a Dana or Carter Nox retroift device using an electronic speed sensor. The "Gas,Mizer" is a single wire coil wound in alternating directions with a non—magnetic core. The coil is encapsulated in a plastic mold. The device also includes two snap—fit electronic suppression cables. This Executive Order is valid provided that installation instructions for this device will not recommend tuning the vehicle to specifications different than those listed by the vehicle manufacturer. Changes made to the design or operating conditions of the device as originally submitted to the Air Resources Board for evaluation that adversely affect the performance of the vehicle‘s po]]ut1on control devices shall invalidate this Executive Order. Marketing of this device using an identification other than that shown in this Executive Order or marketing of this device for an application other than those listed in this Executive Order shali be prohibited unless prior approval is obtained from the Air Resources Board. ~/

"GAS MIZER" EXECUTIVE ORDER D—41 This Executive Order does not constitute any opinion as to the effect that the use of this device may have on any warranty either expressed or implied by the vehicle manufacturer. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF EMDORSEMENT BY THE AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BEMEFITS OF THE "GAS MIZER" DEVICE. No claim of any kind, such as "Approved by Air Resources Board" may be made with respect to the action taken herein in any advertising or other oral or written communication. Section 17500 of the Business and Professions Code makes unlawful, untrue or misleading advertising, and Section 17534 makes violation punishable as a misdemeanor. Sections 39130 and 39184 of the Health and Safety Code provide'as follows : "39130. No person shall install, sell. offer for sale, or advertise, or, except in an application to the board for certification of a device, represent, any device as a motor vehicle pollution control device unless that device has been certified by the 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 section is a misdemeanor." "39184. (a) No person shall install, sell, offer for sale, or adver— tise, or, except in an application to the board for accreditation 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 accredited by the board. No person shall sell, offer for sale, adver— tise, or represent any motor vehicle poliution control device as an accredited device which, in fact, is not an accredited device. Any violation of this subdivision is a misdemeanor."

Executed at Sacramento, California, this ~2 —«day of October, 1974. WILLIAM SIMHONS Executive Officer

State of California AIR RESOURCES BOARD September 27, 1974 Staff Report Evaluation of the Gas Mizer Inc., "Gas—Mizer" Non—Magnetic Coil for Exemption from the Prohibitions of Section 27156 of the Vehicle Code Introduction Gas Mizer, Incorporated, 8399 Topanga Canyon Blvd., Canoga Park, California 91304 has applied for exemption from the prohibitions of Section‘ 27156 of the Vehicle Code for its "Gas Mizer" device. This section prohib{ts the installation of any device which may reduce the effectiveness of the motor vehicle emission control systems. The applicant is requesting the exemption be granted for all 1974 and older model—year vehicles except the following: 1. All vehicles equipped with a breakerless or electronic ignition system. 2.‘ All 1966—70 model—year vehicles equipped with a Dana or Carter NOx retrofit device using an electronic speed switch. II. System Description and Function The device is installed between the OEM ignition coil and distri— butor. It consists of a non—magnetic core (3/4 in. dia. wooden dowel 8—1/2 inches long) with electrical connection provided at

each end. The dowel is wrapped at the coil end with 11 turns of 300 volt FR—1 Rome cable (300 gauge) followed by 47 turns of 23 gauge Nyleze wire. The helix angle of the wrap is then reversed and 105 more turns are made with the Nyleze wire. Another helix angle reversal is made to wrap the last 57 turns at the distributor end. A photograph of the device is shown in Figure 1. The applicant claims that the device will improve fuel economy. III. Device Evaluation A. Applicant‘s Tests Gas Mizer submitted data that is intended to show the effects of the device on fuel economy. A 1973 Pinto was driven 267.4 miles without the device and 288.4 miles with the device over sundnyn surface and freeway routes. Data showing 7—10 percent increase in fuel economy was presented. Because of the limited mileage accumuiation of a test and random driving routes and driving conditions used, the data is inconclusive. ARB Tests Two "Gas Mizer" devices were tested on a 1974 Dodge, 360 CID, EGR and automatic transmission to determine their electrical character— istics. The following are the results of the tests:

Centrifugal Spark Advance — Crankshaft Degrees Gas Mizer Device Engine Speed — RPM Standard Ignition No. 1 No. 2 760 (Iidle) 5.0 4.5 4.0 1000 ’ 10.0 10.0 9.5 1500 ——22.0 23.0 _ ‘23.0 2000 24.0 25.0 24.0 2500 26.0 27.0 26.5 3000 28.0 28.5 ' 28.5 Spark Duration — Microseconds Gas Mizer Device Engine Speed — RPM Standard Ignition No. 1 No. 2 760 {Idle) 11090 _ 1200 1100 2000 900 950 900 Secondary Voltage — Kilovalts Gas Mizer Device Standard Ignition Firing Avaialable Engine Speed RPM Firing Available No. 1 Ho. 2 No. 1 No. 2 760 ({Idie) 12 26 10—13 8—13 20 19 2000 8—10 23 8B—10 7—9 20 19 Secondary Voltage Rise Time — Microseconds Gas Mizer Device Engine Speed — RPN Standard Ignition No. 1 No. 2 760 (Idle) 10—15 10—15 10—15

Device Electrical Resistance — Ohms Device No. 1 — 2.0 Device No. 2 — 2.0 The electrical characteristics of the device are similar to the OEM system. The device may slightly influence the required and available voltage at the spark plug by the addition of the device‘s resistance to the OEM system. The following are the results of idle emission tests performed on the 1974 Dodge: HC_— PPM CO—% Baseline No. 1 ©138 1.0 Device No. 1 117.5 0.78 Baseline No. 2 64 6.19 Device No. 2 64 0.50 No apparent effects were produced by the devices in the idle emission tests. IV. Conclusions and Recommendations It is the opinion of the Staff that the "Gas Mizer" device does not reduce the effectiveness of required emission control systems.

Therefore, it is recommended that Gas Mizer Corporation be granted an exemption from the prohibitions of Vehicle Code Section 27156 for the "Gas Mizer" device for 1974 and older model—year vehicles except for the following: 1 — All vehicles equipped with a breakerless or electronic ignition system. 2. All 1966—70 model—year vehicles equipped with a Dana or Carter NOx device using an electronic speed switch.
