EVALUATION OF AUTOMOTIVE SYSTEMS GROUP, INC.‘S HIPERFLOW INDUCTION SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION Automotive Systems Group, Inc. (ASG) of 6644 San Fernando Road, Glendale, CA, 91201 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for the Hiperflow Induction system designed for installation on the following vehicles: Part Number . Model Years Vehicle Models Displacement H03041 1988—1991 Honda Civic CRX 1. 6L H03042 1992—1995 Honda Civic DX, EX, LX, Si 1. 6L #03042 1992—1995 Honda Civic del Sol S and Si 1. 6L H03045 1994—1995 Acura Integra RS and LS® 1. 8L. H03046 1994—1995 Acura Integra GSR 1. 6L Automotive Systems Group, Inc. submitted installation instructions with drawings and description of the kit. Automotive Systems Group, Inc. has submitted a sample Hiperflow Induction system which was evaluated for this application. II. CONCLUSTONS Based on an engineering evaluation of the Hiperflow Induction system, the staff concludes that Automotive Systems Group, Inc.‘s Hiperflow Induction system will not adversely affect exhaust emissions from the vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that ASG be granted an exemption for their Hiperflow Induction system for installation on the vehicles listed above. The staff also recommends that Executive Order D—377—3 be issued.

IV. HIPERFLOW INDYCTION SYSTEM DESCRIPTION AND OPERATION The Hiperflow Induction system consists of an open element air filter and intake pipe with all the necessary mounting brackets, bolts, screws, and nuts for installation. According to ASG, the Hiperflow Induction system is designed to be less restrictive than the OEM air filter system to allow the engine to gain more horsepower. The Hiperflow Induction séZ;em does not require any significant relocation or modification of any of the OEM emission control components. The Hiperflow Induction system uses a K & N filter made of woven fabric sandwiched between two layers of wire mesh screen and a velocity stack which serves to smooth the incoming air flow. The Hiperflow Induction system does not defeat any emission control devices required— by the manufacturer nor does it alter or circumvent the vehicle‘s on—board diagnostic system. All of the Honda Civic and Acura Integra models in this application have a positive crankease ventilation (PCV) breather hose attached to the original equipment manufactuer‘s (OEM‘s) intake tract. ASG provides a por£ for the PCV breather hose and an extension for this hose since the intake tract requires this hose to be moved slightly upstream from the OEM configuration. The Automotive Systems Group, Inc. Hiperflow Induction system does not affect the tune—up specifications.

v. DISCUSSION The ASG Hiperflow Induction system is designed for installation on the vehicles listed below: Part Number Model Years Vehicle Models Displacement H03041 1988—1991 Honda Civic CRX 1. 6L H03042 1992—1995 Honda Civic DX, EX, LX, Si 1. 6L H03042 1992—1995 Honda Civic del Sol S and Si 1. 6L H03045 1994—1995 Acura Integra RS and LS 1.8L H03046 1994—1995 Acura Integra GSR 1. 6L An engineering evaluation was conducted to determine the impact of the Hiperflow Induction system on emissions. The Air Resources Board‘s (ARB‘s) concerns regaiding the air filter are that the air flow could significantly increase evaporative emissions, changes in the mass air flow measurement could affect exhaust emissions, and the positive crankcase ventilation (PCV) system may be compromised by an open element air filter. Since the ASG Hiperflow Induction system replaces a closed air cleaner housing with an open element filter, the ARB was concerned that gasoline vapors could escape from the manifold, through the open element filter, into the atmosphere. The vehicles for which exemption is requested are equipped with electronic fuel injection, which is designed to eliminate potential gasoline vapor leaks. During static condition, the fuel injectors are designed to operaté by an electromagnet that pulls the injector open against the fuel flow. The ARB has previously reviewed tests conducted on various fuel injector sizes in which fuel flow and pressure were simultaneously increased. The tests —3—

showed that as pressure is increased, the fuel injectors tend to hydraulically lock. This condition causes the injector to be more difficult to open and reduces leaks. In addition, fuel injected vehicles use intake manifolds which are designed to flow air in only one direction, inward to the intake valve. Furthermore, the design of the Hiperflfiw Induction system does not alter the location of the evaporative emissions components or hoses. With these findings, staff concludes there will be no adverse impact on evaporative emissions due to the use of an open element air cleaner. ASG stated that the mass air flow measurement technique used on the vehicles for which the exemption is requested are the manifold absolute pressure sensor for speed—density calculations. The open element air filter does not have a housing or intake ducting which straighten the intake flow to allow for laminar flow. This could cause the intake flow to be turbulent. ASG states that the Hiperflow Induction system does not require alteration or modification of the OEM specifications. The manifold absolute pressure sensors on‘the vehicles listed above are located downstream from tfie air filter element and thus, the pressure sensing and subsequent fuel metering capabilities will not be adversely affected by the Hiperflow Induction system. In addition, pressure sensing capabilities should not be significantly affected by changes in flow conditions caused by an open element air filter. All of the Honda Civic and Acura Integra models in this application have a positive crankcase ventilation (PCV) hose attached to the original equipment manufacturer‘s (OEM‘s) intake tract. ASG provides a port for the PCV breather hose and an extension for this hose since the intake tract requires this hose to be moved slightly upstream from the OEM configuration. Thus the placement of this hose on the Hiperflow Induction system filter should not affect the operation of the system. Additionally, the PCV breather hose is used to

supply fresh air to the crankcase through a one—way checkvalve which does not allow the passage of vapors in the air cleaner direction. Therefore, no emissions impact is expected from this connection. The vehicles for which the exemption is requested are designed to operate in a closed—loop configuration, which is characterized by the Cold—Start CVS—75 Federal Test Procedure driving cycle. While.the vehicle operates under closed— loop configuration, the on—board computer monitors the air/fuel mixture to maintain it near a stoichiometric condition,. The on—board computer receives voltage signals frcm‘the oxygen sensor and interprets them as either richer or leaner than a stoichiometric fuel mixture. Based on the oxygen sensor signal, the on—board computer either ificreases the amount of air flow (to léan the mixture) or increases the amount of fuel (to richen the mixture) to maintain the fuel mixture near stoichiometric. Although the Hiperflow Induction system could change the air flow, the on—board computer will compensate and keep fhe air/fuel mixture at stoichiometric levels during closed—loop operations. Therefore, the Hiperflow Induction system will have no adverse affects on exhaust emissions of the affected vehicles during closed—loop operations. However, during open—loop operations such as quick accelerations, air and fuel is being supplied on demand and the fuel mixture is not necessarily maintained near stoichiometric. Although the Hiperflow Induction system could potentially increase emissions during open—loop operations, the ARB has not established an official test procedure to evaluate emissions during open—loop operations. The ARB, therefore, reserves the right to conduct emissions tests, in the future, as such tests are developed, that will more adequately measure emissions from all driving cycles.
