State of California AIR RESOURCES BOARD Evaluatlon of HKS USA, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibitions of Vehicie Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. January 19, 1989

Evaluation of HKS USA, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibitions of 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, CA 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 HKS USA, Inc. (HKS) has requested an exemption from the prohibitions of Vehicle Code Section 27156 for their air—to—air intercooler system for use on the OEM turbocharged vehicles listed in the appendix. Based on previous comparative tests evaluating the exhaust emission effects of several add—on intercooler kits and the staff‘s engineering evaluation of the intercooler‘s impact on exhaust emisslons from turbocharged vehicles, the staff concludes that the HKS‘s air—to—air intercooler kit wilt not adversely affect exhaust emisslons from vehicles for which exemption is requested. The staff recommends that HKS USA, Inc. be granted an exemption for their air—to—air Intercooler system as requested and that Executive Order D—186 be Issued.

Evaluation of HKS USA, Inc.‘s Air—To—Air Intercooler System for Exemption from the Prohibltlons of Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Adminlistrative Code. 1. | T ILON HKS USA, Inc., of 20312 G@ramercy Place, Torrance, California 90501, has requested an exemption from the prohibitions of Vehicle Code Section 27156 for their air—to—air intercooler system for use on the OEM turbocharged vehicle [isted in the appendix. 11. N L QN Based on previous comparative tests evaluating the exhaust emission effects of different add—on intercooler kits and the staff‘s engineering evaluation of the intercooler‘s impact on exhaust emisslons from turbocharged vehicles, the staff concludes that HKS‘s air—to—air intercooler system will not adversely affect exhaust emissions from vehicles for which exemption is requested. III. RE MENDAT 1 The staff recommends that HKS USA, Inc. be granted an exemption for their air—to—air intercooler system as requested and that Executive Order D—186 be issued.

LV . 1 R LER SYSTEM DESCR! ION AND OPERATION The purpose of the intercooler is to reduce the temperature of the Iintake air/fue! charge going into the turbocharged engine. This reductlon in the intake charge temperature allows a higher charge density (more amount of air per minute flowing through the engine) which means more fuel! into the engine at a glven intake manifold vacuum/pressure. The major components of the HKS air—to—air intercooler system are: aluminum heat exchanger, pressure pipes, cadmium plated brackets, sillcone connector hoses, hose clamps, compressor by— pass valve, silicone vacuum and blow—by hoses. They are packaged with installation hardware and instructions and sold as a kit. The system Is designed using different design concepts, including tubing lengths, diameter and bends, to sult the requirements of the individual vehlcle. The HKS air—to—air Intercooler system heat exchanger is mounted In the vehicies‘ frontal air. stream. The intercooler is spliced Into the original intake air plumbing between the turbocharger compressor and the intake manifold throttle body. During boost conditions, compressed air, normally 230 degrees F, is cooled to 130 degrees F by the HKS Intercooler core being delivered to the engine . Some HKS intercooler systems incorporate a compressor by—pass valve which routes compressor discharge directly into the compressor intake under deceleration. This arrangement prevents impeller deceleration between gear shifts and reduces shock waves in intercooler plumbing and core. ‘

v. D | | HKS air—to—air intercooler system is similar in design concepts and principles as other manufacturers‘ systems that have been exempted by the Air Resources Board. Performance analyses that were previously submitted to the ARB by other manufacturers of similar system indicated that typlcal thermal efficiency of a turbocharger intercooler system ranges between 40% and 84%. Based on predicted efficiency of a heat exchanger on previous air temperature measurements of other exempted intercoolers installed and tested on vehicles and on a review of the device theory of operation, the staff has concluded that the use of an intercooler would not adversely affect vehicle emlissions or result in the degrading of a vehicle‘s driveabillty. In addition, 1t is the staff‘s opinion that the combustion temperature wlll be reduced as a result of cooler intake charge with the use of the air—to—air intercooler system. This reduction in combustion temperature will reduce the formation of NOX gases in the combustion chamber, resulting in less NOX emissions expelled through the exhaust system. HKS air—to—air intercooler system has similar design with Spearco alr—to—alr intercooler system which is exempted by the ARB under E.0. D—140—3. Spearco‘s previous test results demonstrate no adverse effect on the vehicle‘s exhaust emissions of their kit.
