State of California AIR RESOURCES BOARD Staff Report October 5, 1978 Synopsis: This staff report evaluates the "AES—3000 Fuel Saving Device" manufacturered and marketed by Engineering Systems Corporation, 2975 Scott Blvd., Suite 100. Santa Clara, California 95050, for compliance with the requirements of Section 27156 of the Calif— ornia Vehicle Code. Starting with a brief introduction to the device, the report deseribes its operation, the benefit claims the applicant makes, the test data submitted by the applicant, the confirmatory tests done on the device at Air Resources Board‘s Haagen—Smit Laboratory and finally concludes with recommendations, to enable the Exeeutive Officer to arrive at a decision. II.. Introduction: The "AES—3000" is a typical intake manifold vacuum modulated air bleed device which allows an extremely smalil proportion of air to enter the engine through the PCV system. This air bleed is sup— posed to enter only during high and low manifold vacuum éonditions, thereby helping to save a little fuel. A built—in electronic timing device prevents the device from operation during engine starting and warm up periods. A small air filter ensures the cleanliness of the auxiliary air bleed.

IIi. System Description and Function: The "AES—3000" consists of a diaphragm which is to be connected to manifold vacuum. Changes in manifold vacuum causes a small piston, contacting the diaphragm, to reciprocate. A pivotted lever with a contact point picks up the piston motion. The contact point moves between 2 contact poles, making contact with them at the high and Tow vacuum conditions. A solenoid energized by 12 volt d.c. from engine ignition system is in series with the contact lever/contact point circuit. The circuit is complete during the contacting time period. When the solenoid gets energized, it magnetizes a pole, located in its core, which in turn pulls a soft iron clapper. When the clapper is magnetically pulled from its seat, an annular space is created, which allows atmospheric air into PCV line. When the ignition is turned off, the solenoid is not energized. Consequently, the clapper rests on the PCV air bleed inlet, keeping it closed thereby pre— venting the PCV line from contamination during the time when the car is not in operation. A delay circuit prevents the solenoid from being energized as soon as the ignition is turned on. This will not allow any air bleed during starting and warm up periods and so may not interfere with the engine starting characteristics. Since the clapper is magnetically pulled from its rest position against its own weight, it is imperative that the device be installed in an upright position.

The applicant plans to market the device through franchised dealers, who will install the device on a car. After installation, if the electrical components do not function, the chances are that this will go unnoticed. This is due to small amount of air bleed. IV. System Evaluation: A. Applicant‘s Data The applicant submitted a CVS—75 cold start emission and fuel consumption data. The tests were done at Olson Engineering on a 1978 Camaro, with 305 CID engine. The car odometer read only 243 miles at the commencement of tests. The outcome of the tests are summarized in the tables given below: 1978 Camaro with 305 CID, V8 engine and auto transmission.

B. ARB Flow Test A bench flow test was done to find out the amount of auxiliary air allowed into the PCV line, at various manifold vacuum, applied to the sensing diaphragm. To have an idea of product variation, the tests were done on 2 separate devices. The first device showed a maximum air bleed of 0.02 SCFM at 8 inches of Hg vacuum. The second device showed a maximum air bleed of 0.05 SCFM around 9 inches and 24 inches of Hg vacuum. This shows a 250% product variation. Conclusion. and Recommendation The flow through the device is very low, about 1.5% of a typical PCV flow. The staff is of the opinion, based on similar air bleed devices tested in our laboratory in the past, that the installation of the device will have little effect on emissions. Even though the CVS—75 test data show an increase of 5.2% on NO and 5.8% on CO and 4.3% in MPG these couldn‘t be regarded as representative figures, as the car had only 243 miles at the commencement of tests and such variations of emissions and fuel consumption characteristics are common during the break—in period. The staff also feels that with such a small air flow, the instal— lation of the device will have little effect on the improvement of fuel economy.

The staff favors the approval of exemption of the device from the provisions of the Vehicle Code 27156. Executive Order D—85 with its attachment giving list of applicable and nonapplicable models and makes, has been prepared for this device.
