State of California AIR RESOURCES BOARD Evaluation of Omni—Cool Corporation‘s Turbocharger Intercooler Kit No. 8781000 for 1984 Dodge/Plymouth Colt Turbo Vehicles for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. July 5, 1984

SUMMARY Omni—Cool Corporation has requested an update to the existing Air Resource Board‘s Executive Order No. D—138—1. Request is to include their add—on intercooler kit (Blizzard I kit No. 8781000) for installation on 1984 Dodge/Plymouth Colt Turbo vehicles in the exemption. Based on: (1) previous performance analysis of the air—to—air intercooler; and (2) the staff‘s engineering evaluation of the intercooler‘s impact on exhaust emissions from vehicles, the staff concludes that Omni—Cool Corporation‘s add—on turbocharger intercooler kit No. 8781000 will not adversely affect exhaust emissions from vehicles for which exemption update is requested. The staff recommends that Omni—Cool Corporation be granted an updated exemption as requested and that Executive Order No. D—138—2 be issued.

Evaluation of Omni—Cool Corporation‘s Turbocharger Intercooler Kit No. 8781000 for 1984 Dodge/Plymouth Colt Turbo Vehicles for Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance with Section 2222, Title 13, of the California Administrative Code. I. INTRODUCTION Omni—Cool Corporation, of 300—B Pine Avenue, Goleta, California 93117, has requested an update to the existing Air Resources Board‘s Executive Order (E.0.) No. D—138—1. Omni—Cool Corporation has requested to include their add—on intercooler kit (Blizzard I kit No. 87B1000) for installation on 1984 Dodge/Plymouth Colt Turbo vehicles in the exemption. II. CONCLUSION Based on: (1) previous performance analysis of the air—to—air intercooler; and (2) the staff‘s engineering evaluation of the intercooler‘s impact on exhaust emissions from vehicles, the staff concludes that Omni—Cool Corporation‘s add—on turbocharger intercooler kit No. 8781000 will not adversely affect exhaust emissions from vehicles for which exemption update is requested. I1I. RECOMMENDATIONS The staff recommends that Omni—Cool Corporation be granted an updated exemption as requested and that Executive Order No. D—138—2 be issued. IV. INTERCOOLER KIT DESCRIPTION AND OPERATION The purpose of intercooling a turbocharger is to reduce the temperature of the intake air/fuel charge going into the engine. This reduction in intake charge temperature will allow a higher charge density (more mass of air per minute to flow through the engine) which means more fuel into the engine at a given intake manifold vaccum/pressure.

The Blizzard I Intercooler kit consists of a standard sized 63.6 cubic inch air—to—air heat exchanger and 2.250 inch 0.D. interconnecting tubing. The inlet and outlet on the upper and lower plenum chambers of the heat exchanger can be arranged at the factory to allow for either "U" or "Z" flow—through design depending upon ease of installation. A typical "U" flow—through design intercooler is found in Drawing 1. The interconnecting tubing varies in length and bends depending upon the vehicle application. The most severe bend used in any of the kits is 90° with a 3 inch radius (on center line}. All bends are made with a mandrel type bender to lessen shrinkage which would result in increased flow restriction. Connectors and fasteners are of a silicone type which can withstand high temperatures. The heat exchanger is normally mounted in the fresh air stream located near the front of the vehicle. Inlet tubing ducts hot compressed air (150—280°F) from the turbocharger compressor to the heat exchanger inlet where, as it passes through baffles within, the hot compressed air transfers its heat to the fresh (ram) air causing the compressed air temperature to drop (50 to 150°F). The cooled compressed air is then passed out of the heat exchanger to the throttle(s) for induction into the engine. The Omni—Cool intercoolers are not designed to be used with "suck through" turbocharger systems, i.e. ones which compress the air/fuel mixture since the heat exchanger may cause the fuel to condense and remain within it. The Omni—Cool systems are designed only to be used with "blow through" turbocharger systems, i.e., ones which compress the inlet air only.

Y. DISCUSSION Omni—Cool Corporation is making available an add—on turbocharger intercooler kit for the 1984 Dodge/Plymouth Colt Turbo vehicles powered by a 1.6 liter engine. The kit is similar in design and principle as their previously exempted intercooler kits for limited Volvo, Datsun, Saab, Ford and Mercury vehicles exempted under Executive Order D—138—1. The applicant previously performed performance analysis on their intercooler kits. Results 1nidic§ted that the mean thermal efficiency of the air—to—air intercooler ranged from 84% (high) to 40% (low) depending upon the air flow rates (figure 1), and the calculated pressure drop was 1.5 psi at 37 #/min air flow (figure 2). In addition, it is the staff‘s opinion that the combustion temperature will be reduced as a result of cooler intake charge with the use of the turbocharger intercooler kit. This reduction ifi combustion temperature will reduce the formation of NOx gases in the combustion chamber, resulting in the less NOx emissions expelled through the exhaust system. Based on the above discussion, the staff sees no reason for conducting emissions testings on a Dodge/Plymouth Colt for granting Omni—Cool Corporation‘s request.
