                               Staff Report

              Evaluation of the Ideal Incorporated "Mileage
             Master" Device in Accordance with Section 2222,
             Title 13 of the California Administrative Code


      Ideal Incorporated, of 14802 Venture Drive, Dallas, Texas 75234

      has submitted an application requesting an exemption from the

      prohibitions of Section 27156.of,the Vehicle Code.for its "Mileage

      Master" air bleed device for installation on— 1978 and older model

      year vehicles with naturally aspirated gasoline engines.     Vehicles

      with engine displacements Tess than 140 cubic inches or.fue1

      injection are excluded from the exemption.

      Ideal Incorporated represents the "Mi]eége Master" device as being

      idenfica1 to the "Jet Blast" devi;e formerly marketed by BC & L

      Industries, Inc.   The "Jet Blast" is exehpt for 1974 and older

      model year vehicles under CARB E.0. D—28—1.

II.   System Description and Function

      The "Mileage Master" is an air bleed designed to meter small

      amounts of air into an intake manifold under conditions of Tow

      manifold vacuum.   The device con§ists of a spring loaded check

      valve in an aluminum housing.     The housing has a filter covered

      air inlet and two nipples.

  *   For most applications, the device is installed by cutting the

      PCV Tine and inserting the nipples.     High manifold vacuum is

      used to overcome the spring force and close the normally open

      valve.     The valve is allowed to open when intake manifold

      vacuum drops to less than 6 inches of mercury.

III. System Evaluation

      A.   Applicants‘ Data

           Ideal Incorporated has submitted the results of back—to—back

           CVS—75 testing performed by W. R. Grace & Co. on a 1978

           Lincolin Continental Mark V with a 400 CID engine.    The re—

           sults show that the device did not increase the emissions

           level over the baseTine test.

      B.       CARB Evaluation

           A flow test performed by the CARB on the "Jet Blast" in 1974

           determined that the device operates in the range of 0 to 6

           inches of mercury with a maximum air flow of 4.2 CFM.        This

           air flow rate was considered acceptable for engines with a

           displacement exceeding 140 CID.

IV.   ConcTusion and Recommendation

      It is the opinion of the staff that the "Mileage Master" is

      essentially idenfica1 to the previously approved "Jet Blast".

      Therefore, based on the current emissions test and previous air

      flow testing the staff recommends that Ideal Incdrporated be

      granted an exemption from the prohibitions of Vehicle Code Section

      27156 for the "Mileage Master" air bleed device subject to the

      exclusions presented in the introduction.
