Issue Date: October 1983 EVALUATION® OF THE CROSSETT AND SON, INC. PRESCA DIESEL FUEL SAVER DEVICE FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue E1 Monte, California 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the content necessarily reflect the view and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation of use.)

SUMMARY . Crossett and Son, Inc. of 1006 South Avenue B, Washington, Iowa 52353, submitted an application for exemption from the prohibitions in Section 27156 of the California Vehicle Code for the company‘s "Presca Diesel Fuel Saver" (PDFS) device. The applicant has requested that the exemption be granted for the installation of this device on all 1983 and older model—year diesel—fueled motor vehicles. The device is a simple heat exchanger utilizing engine coolant and an electrical heater to heat up the fuel supply to the engine for easy start up in cold weather. The staff, based on engineering principle, evaluated the device and determined that the installation of a fuel heater in series with the diesel engine fuel system will not adversely affect the performance of factory equipped emission control systems . The staff recommends that the ARB exempt the PDFS device from the prohibitions in Vehicle Code Section 27156 and that Executive Order D—141 be issued, allowing the installation of PDFS device on all 1983 and older model—year diesel—fueled motor vehicles.

EVALUATION OF THE CROSSETT AND SON, INC. PRESCA DIESEL FUEL SAVER DEVICE FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE I. INTRODUCTION Crossett and Son, Inc. of 1006 South Avenue B, Washington, Iowa 52353, submitted an application for exemption from the prohibitions in Section 27156 of the California Vehicle Code for the company‘s "Presca Diese! Fuel Saver" device. Vehicle Code Section 27156 prohibits the installation of any device or mechanism which reduces the effectiveness of required emission control systems. This code also authorizes the Air Resources Board (ARB) to exempt a device from the prohibitions if it can be demonstrated that the device, upon installation on the engine, will not adversely affect the performance of existing emission control systems. The applicant has requested that the exemption be granted for the installation of this device on all 1983 and older model—year diesel—fueled vehicles. II. CONCLUSION ‘ The staff evaluated the device and found that the "Presca Diesel Fuel Saver" (PDFS) device will not have a significant adverse effect on emissions from diesel—fueled motor vehicles. The applicant responded to the request of the Board by removing the claims of less toxic emissions in the company‘s sales brochures. The ARB also advised the applicant that the company should be prepared to substantiate the increased fuel economy claims by valid Taboratory tests.

III. RECOMMENDATION Based on an engineering evaluation made on a sample device, production blue—prints, and technical data submitted by the applicant, the staff recommends that the ARB exempt the PDFS device from the prohibitions in Vehicle Code Section 27156 and that Executive Order D—141 be issued, allowing the installation of the PDFS device on all 1983 and older model—year diesel—fueled motor vehicles in California. IV. SYSTEM DESCRIPTION AND OPERATION The "Presca Diesel Fuel Saver" (PDFS} device is a heat exchanger manufactured from a 1/2" diameter X 9‘0" long copper tubing coiled and enclosed in a 4"x4"x9—7/8" case made of mild steel. Attached to each end of the case, is a 1/2" hose fitting to accommodate the circulation of engine coolant through the case. Also, a 3/8" compression fitting is mounted on each end plate to hold the coiled copper tubing in place. Two mounting brackets are welded to the case for installation of the device in the engine compartment. A 150—watt, 120—volt auxiliary heater is inserted into the case for overnight fuel heating as a quick—starting aid. Figure 1 (in the Appendix) shows a typical flow diagram. The device is mounted between the fuel tank and the fuel filter. InstaTlation of this device in a fuel system of a diesel engine equipped vehicle is done by connecting the inlet and outlet fittings to the hot engine coolant supply line and back to the engine lTine. Temperature of the incoming engine coolant is determined by the engine thermostat rating (about 180°F)}. The two ends of the copper coil of the device are connected to the fue] supply coming from the fuel tank and to the fuel filter Tines.

Without the PDFS device the temperature of the fuel supplied to the engine is dependent upon the ambient temperature. If the vehicle is exposed to sub—zero weather temperature, the fuel stored in the fuel storage tank will be at the same sub—zero temperature. Diesel fuel at this temperature tends to congeal. Very poor engine starting will result and causing more unburned fuel to be blown out of the exhaust pipe. With the PDFS device, the diesel fuel from the fuel tank is routed into the heat exchanger where it absorbs heat energy from the hot engine coolant around the coil. The pre—heated fuel may enhance the combustion process in the engine cylinders. An electrical heater rated at 150—watts and 120—volts is inserted in the device for overnight fuel heating to facilitate engine starting in cold weather. V. D1SCUSSION The applicant submitted several customer testimonials including a copy of laboratory particulate test results on their "Presca Diesel Fuel Saver" conducted by Sanitary Engineering Laboratories, Inc., of Cedar Falls, Iowa. The testimonials are very subjective; they were not used in ARB‘s evaluation of the device. The staff, based on engineering principles, evaluated the device and determined that the installation of a fuel heater, such as the PDFS device, in series with the diesel engine fuel system will not adversely affect the performance of factory equipped emission control systems.
