State of California AIR RESOURCES BOARD EVALUATION OF THE CROSSETT AND SON, INC. PRESCA DIESEL FUEL SAVER DEVICE FOR INSTALLATION ON 1988 AND OLDER MODEL—YEAR DIESEL—FUEL MOTOR VEHICLES December 1987

Issue Date: December 1987 EVALUATION OF THE CROSSETT AND SON, INC. PRESCA DIESEL FUEL SAVER DEVICE FOR INSTALLATION ON 1988 AND OLDER MODEL—YEAR DIESEL—FUEL MOTOR VEH1CLES by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue El 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 contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY Crossett and Son, Inc. of 1006 South Avenue B, Washington, lowa 52353, has requested an update to Executive Order (E.0.) D—141—1 dated March 10, 1986, which exempted their "Presca Diese! Fue! Saver" (PDFS) device from the prohibitions in California Vehicle Code Section 27156 for installation on all 1986 and older model—year diesel—fueled motor vehicles. The update requests the inclusion of 1987 and 1988 model—year diesel—fueled motor vehiclies in the exempiion. The device is a simple heat exchanger utilizing engine coolant and an eléctrlcal heater to heat up the fue! subpl} to the engine for easy start up in cold weather. . The staff, based on an engineering evaluation of the fue! systems‘ and engines‘ design of 1987 and 1988 model—year vehicles, determined that the instailation of a fue! heater in seriles with the diese! engine fue! 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 E.0. D—141—2 be issued, allowing the installation of PDFS device on all 1988 and older model—year diesel—fueled motor vehicies.

EVALUATION OF THE CROSSETT AND SON, INC. PRESCA DIESEL FUEL SAVER DEVICE FOR INSTALLATION ON 1988 AND OLDER MODEL—YEAR DIESEL—FUEL MOTOR VEHICLES I. INTRODUCT ION Crossett and Son, Inc. of 1006 South Avenue B, Washington, lowa 52353, has requested an update to Executive Order (E.0.) D—141—1 dated March 10, 1986, which exempted their "Presca Diesel Fuel Saver" (PDFS) device from the prohibltions in California Vehicle Code Section 27156 for installation on all 1986 and older model—year diesel—fueled motor vehicles. The update requests the inclusion of 1987 and 1988 model—year diesel—fueled motor vehicles in the exemption. 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. 11. CONCLUS ION The staff previously evaluatedvthe device and found that the PDFS device will not have a significant adverse effect on emissions from diese!— fueled motor vehicles. The applicant responded to the previous request of the ARB by removing the claims of less toxic emissions in the company‘s sales brochures. The ARB also advised the applicant previously that the company should be prepared to substantiate the Increased fue!l economy claims by vallid laboratory tests.

LET. ’ RECOMMENDATION Based on an engineering evaluation previously made on a sample device, production blue—prints, technical data submitted by the applicant, and the fact that the engines‘ and fuel systems‘ design of the 1987 and 1988 model—year diesel—fueled motor vehicles have not changed significantly from those of 1986 model—year, the staff recommends that the ARB exempt the PDFS device for installation on all 1988 and older model—year diesel—fueled motor vehicles and that Executive Order D—141—2 be issued. IV. TEM DESCRIPT AND AT The "Presca Diese! 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 1§50—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 fuél tank and the fuel filter. Installation of this device in a fue! system of a diese! engine equipped vehicle is done by connecting the inlet and outlet fittings to the hot engine coolant supply line and back to the engine line. Temperature of the incoming engine coolant is determined by the engine thermostat rating (about 180°Fj. The two ends of the copper coll of the device are connected to the fue! supply coming from the fue! tank and to the fue! filter lines.

Without the PDFS device the temperature of the fuel supplied to the engine is dependent upon the amblent temperature. If the vehicle is exposed to sub—zero weather temperature, the fue! stored in the fue! storage tank will be at the same sub—zero temperature. Diesel fue! at this temperature tends to congeal. Very poor engine starting will result and may cause unburned fue! to be blown out of the exhaust pipe. With the PDFS device, the diesel fue! from the fue! tank is routed into the heat exchanger where it absorbs heat energy from the hot engine coolant around the coil. The pre—heated fue! 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 fue!l heating to facilitate engine starting in cold weather . v. 1 LON The applicant previously submitted several customer testimonials including a copy of laboratory particulate test results on their PDFS déevice conducted by Sanitary Engineering Laboratories, Inc., of Cedar Falls, lowa. The testimonials were very subjective; they were not used in ARB‘s evaluat ion §f the device. In response to the applicant‘s request for an update of the existing E.0. D—141—1, the staff compared the fue! systems‘ and the engines‘ design of 1987 and 1988 model—year vehicles. No significant differences were noted between engines‘ and fue! systems‘ design of the diesel—fuel vehicies. Based on its analysis, the staff is of the oplnipn that the installation of PDFS device on 1987 and 1988 diesel fue! vehicles will not affect the performance of factory equipped emission control systems and recommends that the PDFS device be granted an updated exemption from the prohibitions of Vehicle Code Section 27156 for the diesel—fuel motor vehicles.
