State of California AIR RESQURCES BOARD EXECUTIVE ORDER D—117 _ Relating to Exemptions under Section 27156 of the Vehicle Code MPG PERFORMANCE PRODLUCTS VARI—FLOW WATER INJECTOR 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 Sections 39515 and 39516 of the Health and Safety Code and Executive Order &@—45—5; IT IS ORDERED AND RESOLVED: That the installation of the Vari—Flow water injector manufactured by MPG Performance Products of Chatsworth, California, has been found not to reduce the effectiveness of required motor vehicle poliution control devices and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1980 and older gasoline—powered vehicles with engines of 140 CID or less. 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 by the Air Resources Board, that adversely affect the performance gf a vehicle‘s pollution control system shall invalidate this Executive rder. 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 shall be prohibited unless prior approval is obtained from the Air Resources Board. ~Exemption of a kit shall not be construed as an exemption to sell, offer for sale or advertise any component of a kit as an individual device. This Executive Order does not constitute any opinion as to the effect ?hat.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, fifi$R8Xfi%fiSOSFA¥EEOXgEEIEX§$ ggNENbgRSEMENT BY THE AIR RESOURCES BOARD OF CERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF THE VARI—FLOW WATER INJECTOR. 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 untrue or «misleading advertising unlawful, and Section 17534 makes violation ;punishable as a misdemeanor. Section 43644 of the Health and Safety Code provides as follows: "43644. (a) No person shall install, 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." Any apparent violation of the conditions of this Executive Order will be submitted to the Attorney General of California for such action as he deems advisable.

State of California AIR RESOURCES BOARD July 17, 1981 EVALUATION OF THE MPG PERFORMANCE PRODUCTS COMPANY "VARI—FLOW INJECTOR" IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE I. INTRODUCTION MPG Performance Products of Chatsworth, California, has applied for an exemption from Section 27156 of the California Vehicle Code {VC) for an add—on device known as the "Vari—Flow Injector". Exemption is sought for all gasoline—powered motor vehicles. The device was evaluated by bench flow tests and back—to—back Constant Volume Sampler, 1975 (CVS—75) emissions tests, and Highway Fuel Economy tests (HFET}. II. DEVICE DESCRIPTION AND OPERATION The Vari—Flow Injector is a water injection system which sprays water through a nozzle installed in the air cleaner housing into the air horn (intake) of the carburetor. The major components of the system are a water reservoir, an electric pump, a vacuum—actuated proportional control valve, and the spray nozzle. Additional components are a water filter, oil pressure interlock switch, manual on—off switch, and a solenoid valve (Figure 1). The Vari—Flow Injector is designed to inject water into the carburetor inlet only during periods of increased demand for engine power, as evidenced by Tow intake manifold vacuum. When the engine is not running, an oil pressure interlock switch disconnects the water pump and closes the solenoid valve to stop the water flow.

The Vari—Flow is available with five different size nozzles capable of maximum flow rates ranging from 40 to 270 cc/min. One nozzle, appropriate to the size of the engine of the purchaser‘s car, is supplied with each vari—flow unit. Water flow starts at 11 inches of manifold vacuum and increases to maximum flow rate at zero vacuum. III. ARB TEST RESULTS At the request of the ARB staff, the applicant submitted four nozzles for bench testing. The Vari—Flow was assembled as shown in Figure 2 and the flow rates determined at appropriate manifold vacuum increments are shown in Table 1. Table 1 Water Flow vs. Control Vacuum Pump Voltage = 14.5 volt PQINT YACUUM WA T E R F L O W — cc/min in Hg .016" Nozzle .020" Nozzle .025" Nozzle .029" Nozzle 1 o 30 so 210 265 2 3 18* 65 180 230 3 6 18 45 125 170 4 9 15 20 60 65 5 11 0 0 0 0 6 10 2 5 10 10 7 9 13 20 60 70 8 6 18 45 135 165 9 3 40 65 170 235 10 0 55 80 210 270 * Irratic Flow Rate Noted and Verified (1) Two—Hole Nozzle

A plot of these data based upon second order polynomial equations obtained by computer normalization is presented in Figure 3. The large difference between the .020" and the .025" nozzle was discussed with the applicant. The applicant then submitted a two—hole .020 nozzle for testing. This nozzle was not tested because it was apparent that the flow rate would fit within the void area of the curves. IV. APPLICANT‘S TEST DATA The Air Resources Board specified two vehicles to be tested by the applicant according to the CVS—75 test procedure. Data from the first vehicle was submitted on April 10, 1981. The applicant has not been able to complete the second vehicle in a timely manner. The submitted data are: Test Vehicle Year: 1980 Make: Chevrolet ModelT : Chevette (Engine size — CID) Odometer : 14,292 CVS/HEFT TEST CONDITION HC CO NOx ECONOMY DATE g/mi g/mi g/mi MPG* 4—9—81 Baseline 187 3.099 .256 25.5/32.8 4—8—81 w/Device .223 2.850 .197 25.6/32.5 *Rounded values.

The staff finds that there is no significant increase in emissions resulting from the installation of the YVari—Flow water injector on this vehicle. The absence of second vehicle data makes it impossible to ascertain the effect of the Vari—Flow on larger vehicles. V. CONCLUSIONS AND RECOMMENDATIONS The staff finds no evidence that the Vari—Flow water injector will have a significant adverse effect upon the emissions from motor vehicles under 140 cubjc inch displacement. The staff,. therefore, recommends that Executive Order D—117 exempting the Vari—Flow water injector from the prohibitions of VC 27156 be granted.
