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 date 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 installation of all gasoline
powered 1994 and older vehicles, excluding thosed 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
successfully 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 fule 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 (continue to page 2)
-1-
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 solenoid 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, excluding
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.
