       Auto Tech Products of 23681 Schooner Drive, Canyon Lake, California
92587, has applied for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code (VC) for their PCV Valve.      The PCV Valve is

designed for installation on all gasoline powered 1994 and older vehicles,
excluding those equipped with OBD II.   Auto Tech Products submitted a completed

application and other required information.

II.    CONCLUSIONS
       Based on emissions test data of the device, the staff concludes that
Auto Tech Products‘ PCV Valve will not adversely affect the exhaust emissions

on those applicable vehicles for which an exemption is requested.

III.   RECOMMENDATION

       The staff recommends that Auto Tech Products be granted an exemption for

their PCV Valve for instaliation on all gasoline powered 1994 and older
vehicles, excluding those equipped with OBD II.    The staff also recommends that
Executive Order D—372 be issued.
IV.    AUTO_TECH PRODUCTS‘ PCV VALVE DESCRIPTION
       Auto Tech Products‘ PCV Valve has been specifically designed for

installation on all gasoline powered 1994 and older vehicles, excluding those
equipped with OBD II.   The device operates in conjunction with the original
equipment manufacturer‘s (OEM) computer controlled fuel injection system and

emission control system already certified with the stock engine.

       The purpose of modifying the PCV valve of an engine is to vent blow—by

gases from the crankcase into the intake manifold freely regardless of engine
                                        —]—


vacuum.    Auto Tech Products‘ PCV Valve‘s orifice is designed to regulate gas

flow based on the speed of the engine.        This was accomplished by designing the

PCV valve to be activated by the use of a solencoid valve and the addition of a
small switch placed at the throttle linkage.

v.        DISCUSSION OF AUTO TECH PRODUCTS‘ PCV _VALVE
          Auto Tech Products, has requested that the PCV Valve be exempted for

all gasoline powered 1994 and older vehicles, exciuding those equipped with OBD

II.   Comparative emissions test data using the CVS—75 Federal Test Procedure

was conducted on two passenger cars to evaluate the emissions impact of the

device.     Auto Tech Products performed emissions testing at Environmental

Testing Corporation.

          Results of the exhaust emissions test data are shown in Table 1.

          The emissions test data generated at Environmental Testing Corp.

indicates that the HC, CO and NOx emissions of the vehicles, were within the
allowable limits of 0.1 gm/mi or 10 percent increase on HC and NOx and 1.0

gm/mi or 15 percent increase on CO for comparative emissions test data.        The

Air Resources Board did not conduct confirmatory testing to validate the
emissions data submitted by Auto Tech Products.

          Auto Tech Products has submitted all the required information and has

fulfilled the requirements for an exemption.
