State of California AIR RESOURCES BOARD November 5, 1979 STAFF REPORT Evaluation of Sumari Engineering Inc. "TAF Performance Valve" Device for Compliance with the Requirements of Section 27156 of the California Vehicle Code Introduction Sumari Engineering Inc. 544 West Thunderbird Road, Phoenix, Arizona 85023 has submitted an application requesting an exemption from the provisions of Section 27156 of the California Vehicle Code for its "TAF Performance Valve" device for installation on all 1979 and older model year vehicles with engines greater than 140 cubic inch displacement except for the following: 1. Diesel powered vehicles 2. Fuel injected vehicles 3. Chrysler Lean Burn Systems 4. Vehicles equipped with 3—way catalyst II. System Description The "TAF Perforamnce Valve" is an air bleed device that is installed in series with the PCV hose. The device uses a proportional air bleed that is controlled by means of manifold vacuum. The propor— tional air bleed is adjustable to suit different engine applications. The device consists of two chambers, the upper chamber has a vacuum controlled piston connected to an adjustable plunger. A spring is positioned under the piston so that it is normaily open when not in

Evaluation of Sumari Engineering Inc. "TAF Performance Vaive" Device for Compliance with the Requirements of Section 27156 of the California Yehicle Code November 5, 1979 operation. The lower chamber has series connectors for the PCV system and a common port to the upper chamber. The common port has three 4.75 mm (3/16 inch) orifices drilled into it. These orifices allow fresh air to enter the device. The orifice outlets are covered by a porous filter of greater than 20 micron mesh. III. System Function In operation the vehicle is started and manifold vacuum is applied to the upper chamber which overcomes the spring tension and pulls the piston assembly down. The adjustable plunger, which is part of the piston assembly covers the orifices that allow the fresh air into the PCV system. As manifold vacuum is decreased, the spring forces the piston assembly upward and the orifices are uncovered allowing air to bleed in to the PCV éystem. This is caused by the pressure differential of engine operation. The amount of air that enters the PCV system is proportional to the area of the uncovered orifices. The device is designed to be fully closed at idle, partially open at cruise and fully open at wide open throttle.

Evaluation of Sumari Engineering Inc. "TAF Performance Valve" Device for Compliance with the Requirements of Section 27156 of the California Vehicle Code November 5, 1979 IV. Device Testing Sumari Engineering Inc. submitted test data prepared by W. R. Grace and Company on a 1979 Chevrolet Monte Carlo. (See Table 1). The emissions data indicate an increase in carbon monoxide (CO) and a decrease in hydrocarbons (HC), oxides of nitrogen (NOx) and fuel economy (MPG). The percentage differences in emissions data {with and without device) are considered to be within test variability. The Air Resources Board performed confirmatory testing of the "TAF Performance Yalve" at the E1 Monte laboratory. ‘The test vehicle was a 1974 AMC Ambassador station wagon with a V8 engine and automatic transmission. The 1975 CVS Federal Test Procedure was used to determine emissions and fuel economy. The vehicle was in laboratory control during the entire time of the device testing. The vehicle was adjusted to OEM manufacturer specifications before baseline testing and the vehicle did not receive any adjustments or modifications between baseline and device tests except for the installation of the device according to the device manufacturer‘s instal— lation instructions. The emissions results (see Table 2) indicate a decrease in CO, HC, and MPG and an increase in NOx. The percentage increase in NOx emissions is considered to be within test variability.

Evaluation of Sumari Engineering Inc. "TAF Performance Vaive" Device for Compliance with the Requirements of Section 27156 of the California Vehicle Code November 5, 1979 The Air Resources Board also performed flow bench testing and driveability tests on the device. The flow bench test is designed to measure the amount of air that flows through the orifices of the device during actual engine operation. This is accomplished by using an engine dynamometer, flow meter and associated hardware. Since the device is adjustable it was subjected to three phases of flow bench testing at different adjustments. In Phases I and II the device was tested at minimum and maximum flow rates (see Figures 1 and 2). In Phase III the device was reinstalled on the test vehicle and adjusted according to the installation instructions. The device was then transferred back to the flow bench for testing. Phase III represents the flow rate of the device as installed on a vehicle (see Figure 3). The driveability evaluation was performed by a member of the ARB staff who has received specialized training in this field. The vehicle was set to OEM specifications and driven through a prescribed test pattern. The vehicle was then fitted with the device and driven in the same manner over the same course. The evaluation is a comparison between the two tests .

Discussion Phase III of the flow bench tests revealed that the "TAF Performance Valve" had very poor repeatability. The ARB staff requested the applicant to submit additional devices for testing to ascertain whether the repeatability problem was due to the quality of the device or if the original devices were defective. The new devices were then subjected to the same flow bench tests. The test results (Phase IV¥) on the new valves indicated flow rates similar to the original valve except that the new valves had repeatable results (see Figure 4). The applicant informed our staff that they had made minor changes to the design of the adjustable plunger to remedy the repeatability problems. The design change is indicated on the blue prints that were submitted with the original application. The driveability evaluation indicated no negative driveability problems associated with the device. The advertisements that were submitted with the original application had claims of 20% better fuel economy, reduced emissions and better performance. Since the CVS test data did not indicate a 20% increase in fuel economy with the device installed, the applicant was requested to omit all such claims from their advertising

Evaluation of Sumari Engingeering Inc. "TAF Performance Valve" Device for Compliance with the Requirements of Section 27156 of the California Vehicle Code November 5, 1979 material to be used in California concerning fuel economy. Section 43644 of the California Health and Safety Code prohibits device manufacturers from advertising their device as a pollution control device unless certified as such; therefore,the applicant dropped all reduced emissions clauses from their application. VI. Conciusion and Recommendation The emissions results from the two test vehicles indicated that the device did not cause an adverse effect on emissions. Furthermore, the driveability evaluation did not reveal safety or performance problems and the flow bench data exhibited repeatable results. Therefore, based on this information the staff concludes that the installation of this device on specified vehicles will not result in an increase in emissions, and recommends that the Sumari Engineering Inc. "TAF Performance Valve" be granted and exemption from the prohibitions of Section 27156 of the California Vehicle Code with the exceptions noted in the Introduction.
