State of California AIR RESOURCES BOARD March 27, 1974 Staff Report Evaluation of the Albano Enterprises, Inc.> "Air Jet Intake Manifold Air Bleed Valve" for Exemption from the Prohibitions of Section 27156 of the Motor Vehicle Code Introduction A]bano Enterprises, Inc., of Santa Ana, California has applied for exemption from the prohibitions of Section 27156 of the Vehicle Code for its "Air Jet Intake Manifold Air Bleed Valve". This section pro— hibits the installation of any device which reduces the effectiveness of the motor vehicle emission control system. The applicant is request— ing the exemption be granted for 1972 to 1974 model—year vehicles. The applicant was previously granted an exemption for his "Air Jet" device by Resolution No. 70—54—C, dated March 15, 1972, for 1971 and older model—year vehicles. The present application is for a device identical to the previously evaluated valve. II. System Description and Function The "Air det" device is inserted in the PCV line between the PCV vaive and the carburetor or intake manifold. According to the applicant, this device improves engine performance and fuel economy.

"Air Jet" > March 27, 1974 Tfi?s device consists of a filter, metal disc (7/8 inch diameter, 1/4 inch high), orifice plate (10 holes, .094 inch diameter/hole), > two springs, threaded top plate {(10 holes, .094 inch diameter/hole), — and metal housing with two 3/16 inch ID ports — used to insert the valve in the line which connects the PCV valve to the carburetor plate — and an air inlet port of 1 incthD opening; this opening is vented to the atmosphere. The device has a modulating poppet which controls the amount of air leak into the intake manifold. Engine vacuum determines the degree of valve opening. High engine vacuum ({deceleration, low cruise and idle operating modes) partly closes the valve, thereby reducing the amount of air flow allowed. The valve is opened to its maximum position at low manifold vacuum (wide open throttle or heavy accel— eration) which results in the highest air flow through the device. The valve is also open when the engine is not operating. A disc is inserted between the orifice plate and threaded plate to prevent possible flame propagation from excessive back pressure. III. System Evaluation A. Applicant‘s Data The applicant submitted exhaust emission and bench flow data on his device. Emission tests were conducted on 1971 and older model—year vehicles with engines over 140 CID which were not re— presentative of vehicles for the model years specified in the

"Air Jet" March 27, 1974 _ present application. Some tests were also performed at 55 mph which were not conclusive to determine the effects of the device on emissions. The applicant submitted total air flow data to the engine by measuring the combined flow through the air bleed port and through the PCV valve connection. Maximum total air flow of 1.8 CFM to the engine occurred at 0 inches to 10 inches Hg. At higher vacuum ranges 10 inches to 20 inches Hg., the flow to the engine was approximately 0.80 CFM. Bench Flow Test Performed by ARB The Air Resources Board laboratory conducted two bench flow tests with two "Air Jet" devices. These tests measured the air bleed rate by varying the vacuum downstream from the valve with one of the in— let ports closed. The ranges of vacuum used in the tests are those experienced during normal engine operation. In the two tests, the maximum flow rates of 2.2 to 3.1 CFM were observed when the vacuum varied between 0 inches to 6 inches Hg. Under normal road load, vehicles operate in this vacuum range for a minimal period. The staff considers the volume of air that flows through the Air Jet into the intake manifold during this period to be insignificant. The maximum flow rates were 0.57 CFM to 0.37 CFM for the two tests when the vacuum exceeded 6 inches Hg ({Reference Figures 1 and 2). The ARB staff uses maximum air—bleed limits as a basis of jJudgment for the leaning effect of the device. The tests show the air flow per— mitted by this device exceeded the established maximum flow limit for engines having 140 cubic inch displacement (CID) or less, but met the criteria for vehicles with engines having greater than 140 CID. 3.

"Air Jet" March 27, 1974 ~ C. Exhaust Emission Previous exhaust emission criteria were established for 1966—1970 model—year engines using various air bleed devices. The allowable air bleeds are 0.5 CFM for engines with 140 CID and smaller and 0.90 CFM for engines with greater than 140 CID. Due to the more stringent exhaust emission control requirements for 1971 and later model—year vehicles, the maximum air bleed has been established at 0.30 CFM for engines with 140 CID or smaller and 0.50 CFM with engines larger than 140 CID. These values have been judged by the staff to not have a significant effect. on the performance of the exhaust emission control system. D. fuel Evaporative Emissions Since the air bleed port of the valve is normally open with the engine shut off, fuel vapor from the engine induction system can escape to the atmosphere directly through the valve. The Air Resources Board laboratory conducted a test on a 1972 350 CID Chevrolet to measure the quantity of fuel vapor that would escape to the atmosphere by the charcoal canister technique. To stabilize engine temperatures, the vehicle was operated on the dynamometer with the "Air Jet" device installed. Inmediately following the warm—up period the canister was installed for the soak test. The vehicle was placed in the soak room for twelve hours before a gravimetric measurement of the canister weight change was made. Based on the results of the test, the 0.3 mommnomnmmenimnmngn nrrmniys ns ns ce en

"Air Jet" ' . March 27, 1974 ~a grams of fuel vapor escaping directly through the device is not significant relative to the standard of 2 grams of hydrocarbons per test allowed by Federal Regulations. IV. Conclusions and Recommendation The air flow permitted by this device is greater than the established criterion for vehicle engines having 140 CID or smaller, but less than permitted for engines larger than 140 CID. The staff is of the opinion that the "Air Jet" device would therefore be in violation of Section 27156 of the Vehicle Code for vehicles having 140 CID or smaller engines. Therefore, the staff recormends that Albano Enterprises, Inc., should ‘be granted an exemption from the provisions of Section 27156 for 1972 to 1974 model—year vehicles with engines greater than 140 CID.
