                    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

)




            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.

            + 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

             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.

 V.   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.
