Pursuant to the authority vested in the undersigned by Section 39023 of the Health and Safety Code; IT IS ORDEREDAND RESOLVED: That the installation of "Manfredi Fuel Booster" injector system manufactured by Manfredi Enterprises, Inc. of Cleveland, Ohio has been found to not reduce the effectiveness of required motor vehicle pollution control devices and, therefore, is exempt from the prohibitions of Section 27156 of the Yehicle Code for 1974 and older model— year vehicles with engines of 200 cubic inch displacement and larger. This exemption is valid on those units which meet the following requirements: {1) The name "Manfredi Fuel Booster" and Model No. 200 is identified on the container. {2) The fiow lHimiting check vaive (Model No. 200A) is incorporated in the unit. (3) The vaporous mixture is admitted into the existing PCV system of the engine. {4) The use of water in warm weather or 50% isopropyl—alcohol water mixture for cold weather is specified. . 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 pollution 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 shall be proh1o1ged unless prior approval is obtained from the Air Resources Board. 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.

State of California ‘ . AIR RESOURCES BOARD May 13, 1974 Staff Report Evaluation of the Mafifredi Enferprises, Inc. "Manfredi Fuel Booster" Yapor Injector System For Exemption from the Prohibitions of Section 27156 of the California Motor Yehicle Code I. Introduction Manfredi Enterprisesy Inc. of Cleveland, Ohio, has applied for exemption from the prohibitions of Section 27156 of the California Motor Vehicle Code for its "Manfredi Fuel Booster" Yapor Injector System. This section prohibits the advertising, sale, and installation of any device which alters or modifies the performance of any motor vehicle poliution control device or system. The applicant is requesting . that the _exemp‘m‘on be granted for 1974 and older model—year vehicles with engines 200 cubic inch displacement (CID) or larger. An exemption to Section 27156 was issued for the "Manfredi Fuel Booster" — by Resolution No. 72—99 dated June 21, 1972 to Charles Kolton Enterprises for 1970 and older model—year vehicles with engines 200 cubjc inch diép]ace- ment or larger. This device included a flow limiting check valve. In this application the manufacturer submitted a "Manfredi Fuel Booster" without the check valve. The data submitted by the applicant indicated the device would adversely affect the performance of the emission control system. Based on this data, the applicant was informed by the

"Manfredi Fuel Booster" YVapor Injector System May 13, 1974 staff that a recommendation for an exemption to Section 27156 could not be made for this design. The applicant subsequently modified his device to include a flow limiting check valve. 11. System Description This device consists of a fluid container identified by Model No. 200, rubber hose, check valve (Part No. 200A) and a plastic tee. A rubber hose provides the connection between the engine and the plastic fluid container mounted in the engine compartment. Figure 1 is a schematic ‘of the device showing how the fluid vapor is admitted into the engine through the PCY system. Manfredi Enterprises, Inc. specifies the use of water in warm climates and a 50% isopropyl alcohol—water mixture in cold weather. According to the applicant, this formulation would improve engine perforfiance and fuel economy. The plastic fiuid container has a filtered air inlet port {1) and an electric motor (2) to circulate the inlet air. Connected to the motor is a hollow conical shaped shaft (3) with an impeller on the upper end which afdes in the air circulation. According to the manufacturer, the function of the motor is to agitate the fluid to enhance the rate of vaporization. The outlet rubbef hose contains a spring loaded plastic check valve (4) which is inside the plastic container. This Va?ve restricts the quantity of air flow at high vacuum {idle and cruise

"Manfredi Fuel Booster" Vapor Injector Sys tem May 13, 1974 i conditions) and allows a higher air flow rate at low vacuum (high speed and wide open throttle conditions}). The rubber hose {(5) connects the air outlet port of the device to a tee connecting the device to the PCV line. 111. System Function When the container‘s lower chamber (7) is full of liquid, the rotation of the motor shaft is sufficient to blow a film of water on the tray (8). By applying vacuum on the tee of the PCV line, vaporization of the water on the tray is enhanced. However, when the lTower chambers are half full with water, the rotating shaft is insufficient to pump the water onto the tray. Under this ;onditicn the rotating impelier blades on the shaft blows air across the tray.. The fluid levels never reach sufficfent height that would lead to conditions of injecting water into the intake manifold because of the presence of overfill holes on the container. IY. System Evaluation The following discussion summarizes the applicant‘s data and the bench flow test performed by the Air Resources Board Laboratory. A. Applicant‘s Emission Data The applicant submitted back—to—back baseline and device Hot CVS I emission tests performed by Olson Laboratories of Anaheim, California. These tests were performed on the device without the check valve. A

"Manfredi Fuel Booster" Vapor Injector System _ May 13, 1974 ) 1974 Buick Apollo with a 250 éubic inch displacement engine and automatic transmission was selected as the test vehicle. The following table summarizes the appiicant‘s emission data. In all cases an adverse effect on the exhaust emission control system was reported for the device without the flow limiting check valve.

CO NOx Water —32.3 —16.0 +20.3 Water isopropyl— +25.8 +11.5 — 6,78 alcohol — c Air +61.3 +17.3 —11.3 + Denotes increase in emissions compared to baseline. As stated previously, this data is not considered applicable to the present design of the device because the flow limiting check valve was not included in the emission tests. Air Resources Board Bench Flow Test The Air Resources Board staff uses maximum air flow limits as a basis of judgement for the leaning effect of the device. These established air flow limits are judged by the staff to not adversely affect the performance of the emission control system. The Air Resources Board Laboratory conducted two bench flow tests, one without the check valve and one with the check vaive, by measuring the air flow rate under various vacuum 1200200000000omovemamniganne

"Manfredi Fuel Booster" Yapor Injector System May 13, 1974 y' conditions. Air flow rates without the check vaive indicate a range in flow capacity of 0.8 to 2.2 cubic feet per minute {CFM) over the vacuum range 6 to 20 inches Hg. {reference Figure 2). However, air flow rates with the check valve indicate a maximum flow of 0.52 CFM at 6 inches Hg. vacuum. Between é and 20 inches vacuum Hg., the air flow rate decrease from 0.52 to 0.27 CFM. (Reference Figure 3.) The results without the check valve showed the air flow permitted by. the device exceeded the established lHimits. Therefore an adverse effect on emissions would be'expected without the check . valve. This fact was substantiated by the applicant‘s data. If the device includes the check valve, the tests showed the air flow permitted does not exceed the limits established for the model—year vehicles and engine specified in this application, except in instances of low engine vacuum. Although the Timit is exéeeded at low engine vacuum, the percentage of time which the vehicle operates in this range is minimal.

Conclusion & Recommendation The staff is of the opinion that the "Manfredi Fuel Booster" vapor injector system incorporating the flow limiting check valve would not have an adverse effect on the existing pollution control system. Therefore, the staff recommends that Manfredi Enterprises Inc., be granted an exemption for its "Manfredi Fuel Booster" for 1974 and older model—year vehicles with engines 200 CID and larger.
