                                       SUMMARY




           — En—Ovation Technology,   Inc.   of 963 E.   Detroit Street,   Chandler,

Arizona 85225,    has applied for exemption from the prohibitions in Section


27156 of the California Vehicle Code for the Environmental Valve (En—Valve)

The device is designed for installation on 1994 and older model—year gasoline

vehicles excluding those vehicles certified with the On—Board Diagnostic II


{OBD II) system.

            En—Ovation Technology, Inc. has submitted a complete application

with all the required information.       This device is used in place of the PCV

valve to filter crankcase emissions by removing all blowby from the crankcase

and allows the engine to run at a leaner air/fuel mixture.           Based on emission

testing performed on two vehicles (a 1993 Honda Accord and a 1994 Chevrolet

Pick—up)   by En—Ovation Technology,    Inc.,    the staff believes that the En—


Ovation device will not have any adverse effects on the exhaust emissions from

gasoline vehicles excluding those vehicles certified with the On—Board

Diagnostic II    (OBD II) system.

            The staff recommends that the En—Valve device be exempted from the

prohibitions in Vehicle Code Section 27156 and that Executive Order D—422 be

issued.

             EVALUATIOļ¬ OF EN—OVATION TECHNOLOGY, INC.‘S ENVIRONMENTAL
           VALVE DEVICE FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE
                 CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222,
                   TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS



I.          INTRODUCTION


            En—Ovation Technology,    Inc.   of 963 E.   Detroit Street,   Chandler,

Arizona 85225, has applied for an exemption from the prohibitions of Vehicle

Code Section (VC) 27156 for the Environmental Valve (En—Valve) device which is

designed for installation on 1994 and older model—year gasoline powered

vehicles excluding those vehicles certified with the On—Board Diagnostic II

(OBD II)   system.   The applicant submitted installation instructions and

specifications of the device for our evaluation.




II.         coNCLUSITONS

            Based on the emission test results performed on a 1993 Honda Accord

and a 1994 Chevrolet pick—up truck along with information submitted, the staff

has determined the En—Valve will not have any adverse effects on the exhaust

emissions from gasoline vehicles excluding those vehicles certified with the

On—Board Diagnostic II     (OBD II)   system.




III.        RECOMMENDATION


            The staff recommends that En—Ovation Technology,        Inc. be granted an

exemption from the prohibitions in California Vehicle Code Section 27156 for

the En—Valve device and that Executive Order D—422 be issued.


Iv.       DEVICE DESCRIPTION

          The En—Valve is an add—on device used with the PCV system to filter

crankcase emissions.   The En—Valve is a plastic cylindrical device

approximately 2 inches long with a 1 inch outer diameter.      The En—Valve

replaces the original equipment PCV valve.      The device has two chambers

separated by a flexible fluorocarbon disk that acts as a valve and creates a

two to three inch vacuum in the crankcase.      The applicant claims this removes

all blowby and allows the engine to run at a leaner air—fuel mixture.         This

constant vacuum is created by disconnecting and capping the PCV fresh air hose

inlet located near the air filter.    The device is completely automatic and has

no adjustments.   It ocpens, modulates and closes according to the blowby that


is present in the crankcase.   The applicant claims that the En—Valve has the

capacity to breathe five times more in volume than the original PCV valve when

needed.   Installation instructions are shown in the Appendix.




v.        DISCUSSION

          En—Ovation Technology,   Inc.   claimsg that using their device creates a


certain amount of vacuum in the crankcase and crankcase reservoir.       As long as

this vacuum is present no blowby exist in the crankcase regardless of the

condition or operating mode of the engine.      The applicant states this creates

a much cleaner crankcase environment for a cleaner.burning engine and more


efficient air/fuel mixture by eliminating the presence of blowby.       The

applicant further states that the removal of this blowby allows the engine to

run more efficiently and helps reduce exhaust emissions.       The Air Resources

Board did not perform tests to confirm these claims.

          Two vehicles were selected to evaluate the En—Ovation Technology,

Inc.‘s En—Valve device.   A 1994 Chevrolet pick—up truck with a 4.3L engine and

a 1993 Honda Accord with a 2.2L engine.


One cold—start CVS—75 Federal Test Procedure (FTP) was conducted on each

vehicle to determine emissions of hydrocarbons (HC), carbon monoxide (CO) and

oxides of nitrogen    (NOx).   The emission test were conducted at Environmental


Testing Corporation in Orange, California.          The Air Resources Board did not

perform confirmatory testing.      A summary of the test results are shown below:

                           Environmental Testing Corporation
                           (Based on Cold—Start CVS—75 FTP)

1993 Standard      0 .25                  3 .4                     0.4

          The test results from the exhaust emission tests show that the two


vehicles with the En—Valve are below the new vehicle standards for the model

years indicated.     Therefore,   based on the test results,   the staff concludes


that the installation of En—Ovation Technology,         Inc.‘s En—Valve will not have

an adverse effect on exhaust emissions on the vehicles for which the exemption


is requested.     En—Ovation Technology, Inc. has submitted all the required

information and fulfilled the requirements for an exemption.
