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. Table 1 CVS—75 TEST RESULTS NMHC CO Nox 1992 Mazda Miata 1.6L Device 0.27 2.59 0.68 Test wt. 2500 lbs.

Base) ine 0.095 1.165 0.337 H.P. 9.0 Difference 0.001 0.184 0.075 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. «g—
