State of California AIR RESOURCES BOARD EVALUATION OF DKS TECHNOLOGIES, INC.‘S FUEL STABILIZER SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156, AND SECTION 2222 OF TITLE 13, CALIFORNIA CODE OF REGULATIONS August 1997

EVALUATION OF DKS TECHNOLOGIRS, INC.‘S FUEL STABILIZER SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156, AND SECTION 2222 OF TITLE 13, CALIFORNIA CODE OF REGULATIONS by Mobile Source Operations Division 9528 Telstar Avenue El Monte, CA 91731—2990 (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 DKS Technologies, Inc. of 2226 Northpoint Parkway, Santa Rosa, California 95407, has applied for an exemption of their DKS Fuel Stabilizer System (Fuel Stabilizer) from the prohibitions in Vehicle Code (VC) Sections 27156 and 38391, in accordance with Section 2222 of Title 13, California Code of Regulations (CCR). The Fuel Stabilizer is for installation on 1997 and older model—year diesel engines utilizing liquid coolant. It is designed to optimize diesel fuel temperature for better performance. The applicant claimed that increase in diesel fuel temperature will result in fuel consumption and emissions benefits. However, the applicant did not provide appropriate test data to support their claims. Similar device previously exempted by the Air Resources Board (ARB) showed that diesel fuel stabilizer does not interfere with the pollution control systems of diesel engines. Based on the above, the staff recommends that the exemption be granted as requested and that Executive Order No. D—437 be issued to enable DKS Technologies, Inc. to market the DKS Fuel Stabilizer System in California.

EVALUATION OF DKS TECHNOLOGIES, INC.‘S FUEL STABILIZER SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156, AND SECTION 2222 OF TITLE 13, CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION DKS Technologies, Inc. of 2226 Northpoint Parkway, Santa Rosa, California 95407, has applied for an exemption from the prohibitions in Vehicle Code Sections 27156 and 38391 for their DKS Fuel Stabilizer System, in accordance with Section 2222 of Title 13, California Code of Regulations (CCR). The DKS Fuel Stabilizer System is an add—on device designed to raise the temperature of diesel fuel to optimum operating level, and also ensure that the temperature does not exceed engine \manufacturer’s specification. The Fuel Stabilizer is designed for installation on 1997 and older model—year vehicles powered by diesel engines and utilizing liquid coolant. 11. CONCLUSTON The applicant did not submit appropriate emissions test data to the ARB; however, the ARB has previously granted exemption to an add—on device that operates on the same principle as the DKS Fuel Stabilizer System. Based on the above, and staff‘s engineering evaluation, it was determined that the installation of the DKS Fuel Stabilizer System on applicable vehicles will not result in any adverse effect on the pollution control system of the vehicles. III. RECOMMENDATION Staff recommends that the exemption be granted as requested and that Executive Order No. D—437 be issued, permitting the advertisement, sale, and installation of the PKS Fuel Stabilizer System on applicable vehicles. IVv. DEVICE_ DESCRIPTION DKS Technologies, Inc.‘s Fuel Stabilizer System consists of heat , exchanger, Goyen solenoid valve, and temperature sensor. The heat exchanger is made of stainless steel plates which are copper brazed together at high temperature to make the heat exchanger rugged and leak—proof. Engine coolant passing through the heat exchanger heats incoming fuel to the desired temperature. The unit is compact but has a wide range of application. The temperature sensor monitors the temperature of the fuel leaving the heat exchanger. Signal from the temperature sensor enables the electronically operated Goyen solencid valve to modulate the coolant flow to ensure that engine manufacture‘s specifications on fuel temperature are not exceeded. The applicant claims that installation of the device will result in increased gas mileage and emissions reduction. However, the applicant has not provided data from appropriate test procedures to substantiate their claims.

v. DEVICE EVALUATION DKS Technologies, Inc. has not provided test results using appropriate emissions test procedures for diesel vehicles. The ARB did not require testing on the DKS Fuel Stabilizer System. The ARB has previously granted exemption to a device that operates on similar principle as the DKS Fuel Stabilizer System. By engineering evaluation, staff has determined that the DKS Fuel Stabilizer System will not reduce the effectiveness of the pollution control system of applicable diesel vehicles. In view of the above, staff recommends that DKS Technologies, Inc. be granted a Vehicle Code Section 27156 Exemption based on compatibility with pollution control systems of applicable vehicles.
