                                  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.

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.
