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 G—45—5;

IT IS ORDERED AND RESOLVED: That the installation of the "HZO Vapor
Injector" manufactured by Dis—Aut Enterprises, P.0. Box 1699%; Ontarto.
CA 91762 has been found not to reduce the effectiveness of required
motor vehicle polilution control devices and, therefore, is exempt from
the prohibitions of Section 27156 of the Vehicle Code for 1980 and older
model year vehicles with conventional PCV systems.

This device consists of a glass bottle, rubber hose, mounting bracket,
plastic tee, and a bottle cap with a vapor outlet port, air inlet port,
and water fill port. This exemption is valid on those units which meet
the following requirement:

     (1)   The names "H,0—Vapor Injector" and "Dis—Aut Enterprises" are
           identified og the unit.

     (2)   The vapor outlet port of the device incorporates a 0.022—inch
           diameter orifice.

     (3)   The vaporous mixture is admitted into the existing PCV
           system of the engine.

     (4)   Water is specified as the working fluid.

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 lTisted in this Executive Order shall be prohibited unless

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
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 ENDORSEMENT BY THE AIR RESOURCES BOARD OF
ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY
ALLEGED BENEFITS OF THE "H,0 Vapor 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

     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
     poilution control device as a certified device which, in fact, is
     not a certified device. Any violation of this subdivision is a

                   Evaluation of the Dis—Aut Enterprises
                    "H,0 Vapor injector" In Accordance
                  wichSection 2222, Title 13, California
                            Administrative Code


      Introduction

      Dis—Aut Enterprises has applied for exemption of its ”H20 Vapor

      Injector" from the prohibitions of Section 27156 of the Vehicle

      Code.   This application will update Executive Order D—39 which

      exempted 1974 and older model vehicles to include 1975—80 model!

      vehicles.


II.   Device Description and Function

      The "HZO Vapor Injector" is designed to bleed vapor into the PCV

      vacuum hose through a 0.022 inch diameter metering orifice.      The

      device consists of a glass jar with an air inlet tube, water filler

      and orifice in the cap.    Air is drawn through the inlet tube to the

      bottom of the jar where it escapes through holes. in the tube.     As

      air rises through the water in the jar it picks up moisture.      The

      moisturé—]aden air is then drawn through the 0.022 inch orifice to

      the intake manifold via a tee in the PCV hose.


    A more complete description of the function of the H20 Vapor

    Injector may be found in the ARB Staff report dated September 4,

    1974.                |

III. Evaluation

    Previous flow bench testing of the H20 Vapor Injector indicates

    that the maximum flow at high vacuum will be less than 0.24 SCFM

    through the 0.022 inch diameter orifice.   The system design has

    not changed since the original testing was performed in 1974;

     therefore, no change in air flow should occur.


    The Tow air flow rates will have little effect on idle air/fuel

     ratio, even on a small displacement engine.   As intake manifold

     vacuum drops, the effect of lower vacuum is to decrease the air

     flow rate through the device.   This, combined with higher engine

     air flows under low vacuum, makes the device‘s contribution negligible.


     The applicant has eliminated secondary air leaks noted in the

     original staff report by sealing the cap to the glass reservoir

     and subjecting each unit to a vacuum leak down test.


     The applicant has agreed to delete all claims for fuel economy

     benefit from his advertising literature and packaging labels

     since such claims are not substantiated by test results.


IV.   Conclusion
      It is the staff‘s opinion that the installation and use of the

      "HZO Vapor Injector" will not cause emissions from newer

      motor vehicles to increase because of the extremely low air

      flow rates involved.


      The staff recommends that Dis—Aut Enterprises be granted an

      exemption from the prohibitions of VC. 27156 for the "HZO Vapor

      Injector" for 1980 and older model vehicles with conventional

      PCV systems.
