 EVALUATION OF HYPERMAX ENGINEERING, INC.‘S ADD—ON AIR—TO—AIR INTERCOOLER KIT
       FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156
               IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                         CALIFORNIA CODR OF REGULATIONS



I.     INTRODUCTION

       Hypermax Engineering,   Inc.   (Hypermax) of 255 E. Route 72, Gilberts,

Illinois 60136, has applied for an exemption from the prohibitions in Section

27156 of the California Vehicle Code (VC) for their add—on air—to—air

intercooler kit for 1983—1987 Ford Motor Company vehicles powered by

the Navistar International 6.9L heavy—duty diesel engine and 1988—1992 model—

year Ford Motor Company vehicles powered by a 7.3L Navistar International

heavy—duty diesel engine.

11.    CONCLUSIONS

       Based on previous comparative tests evaluating the effects of several

add—on intercooler systems on exhaust emissions and the staff‘s evaluation of

the intercooler impact on exhaust emissions from turbocharged vehicles, the

staff concludes that the Hypermax‘s intercooler system will not adversely

affect exhaust emissions from vehicles for which the exemption is requested.

III.   RECOMMENDATION

       The staff recommends that Hypermax be granted an exemption for their

add—on air—to—air intercooler system as requested and that Executive Order

D—175—3 be issued.

IV.    INTERCOOLER KIT DESCRIPTION

       The purpose of the Hypermax intercooler system is to reduce the

temperature of the intake air charge into the turbocharged engine.     This

reduction in the intake charge temperature allows a greater charge density

{more mass of air flowing through the engine) to enter the combustion chamber

which means more fuel into the engine at any giyen intake manifold pressure

and, therefore, more power output of the engine.     Also, the reduction in the

intake charge temperature would result in lower combustion/exhaust temperature.


       The major components of the air—to—air intercooler system include a heat

exchanger and inter—connecting bent tubing along with the necessary nuts,

bolts, clamps, washers and brackets necessary to assemble the kit.     The

compressed air from the turbocharger enters the heat exchanger which uses

ambient air as a cooling medium.     The air—to—air heat exchanger is located in

such a way that the heated charge air flows through one section and ambient air

flows through the other section,    cooling the heated compressed charge air.     The

cooled compressed air is then passed out of the heat exchanger to the

throttle(s) for induction into the engine.     There will be a pressure drop when

the air passes through the heat exchanger which varies depending on the size of

the heat exchanger, the temperature of the cooling medium (ambient air) and the

available flow rate of the cooling medium.

       The inlet and outlet pipes of the Hypermax air—to—air intercooler kit

are made from steel tubing.     No emission control components are removed,

disconnected or relocated when the air—to—air intercooler kit is installed.

Installation instructions,    included in every kit, show how to properly install

the Hypermax intercooler kit.     Appendix A shows the installation instructions

including the part numbers.

       V.   DISCUSSION

            The Hypermax add—on air—to—air intercooler is designed for

installation on 1983—1987 Ford Motor Company vehicles powered by a 6.9L

Navistar International heavy—duty diesel engine and 1988~1992 model—year Ford

Motor Company vehicles powered by a 7.3L Navistar International heavy—duty

diesel engine.     Hypermax‘s intercooler kit is similar in design concepts and

principles as other manufacturers‘ systems that have been exempted by the Air

Resources Board.    According to the performance analysis previously submitted by

other manufacturers seeking exemption, the thermal efficiency of the

intercooler system ranges between 40 percent and 84 percent.


            Based on predicted efficiency of a heat exchanger and a review of

the intercooler kit, the staff believes that the Hypermax‘s add—on air—to—air

intercooler kit will not adversely affect a turbocharged vehicle‘s emissions or

degrade a vehicle‘s driveability.

      DIESEL CONTROLLER FOR AN EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE
           SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                            CALIFORNIA CODE OF REGULATIONS


I.      INTRODUCTION

            Hypermax Engineering,               Inc.   of 255 E Route 72,           Gilberts,    Illincis

60136 has applied for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code (VC) for their Diesel Controller for 1993—97

trucks equipped with a turbocharged Navistar 7.3L diesel engine.

II.      CONCLUSIONS

             Based on submitted emissions test data,                       the staff concludes that

Hypermax Engineering,        Inc.‘s Diesel Controller will not adversely affect

exhaust emissions from the vehicles for which the exemption is requested.

III.     RECOMMENDATION

            The staff recommends that Hypermax Enginsering,                           Inc.   be granted an

exemption for their Diesel Controller for installation on 1993—97 trucks

equipped with a turbocharged Navistar 7.3L diesel engine.                               The staff also

recommends that Executive Order D—175—12 be issued.

IV.    DIESEL CONTROLLER DESCRIPTION

            The Diesel Controller manufactured by Hypermax Engineering has been

specifically designed for installation on 1993—97 trucks equipped with a

turbocharged Navistar 7.3L diesel engine.

            The purpose of using Hypermax‘s Diesel Controller is to enhance the

performance of the 7.3L diesel engine during high torque and wide open

throttle conditions       (WOT).

            The new electronic control module (ECM), the Hypermax Diesel

Controller,    is a direct replacement ECM that has been modified.                              The

modifications made are designed to interface with the existing software and

hardware to improve the performance of the engine.                            The principal idea behind

the modifications is to increase the injector pulse width and allow more fuel

to be delivered to the engine during 50 percent or greater throttle position.

The manufacturer claimed that by increase the pulse width at 50 percent

throttle,   the driver would not experience any sudden surge in power that may

result if the injector pulse width is increased at or near WOT.                                 Hypermax

claims that these trucks are usually used for long haul travel and do not

exceed the 50 percent throttle position during normal driving.                               Since these

trucks are factory turbocharged and usually are equipped with manual

                                                       ~1—


transmissions, throttle position between 50 and 100 percent is rarely used,

except for high load and acceleration conditions.

v.          DISCUSSION OF THE DIESEL CONTROLLER

            A 1995 Ford F—350 equipped with a 7.3L turbocharged diesel engine

was used for the evaluation of the Diesel Controller.              Testing consisted of

one Cold 505 in the baseline configuration and one Cold 505 in the modified

configuration.     The dynamometer inertia weight and horsepower settings were

8000—1bs.    and 19.3—hp.,   respectively.       The emissions testing was conducted by

Roush Laboratories for Hypermax, data was evaluated against the vehicles‘s

baseline emission levels.       Table 1 list those results.

                                           Table 1.

                                     (gm/mile)

                   HC           co               NOx          Particulates

Baseline         0.89          4.68              7.8            0.15

Modified         0.84          4.46              7.4            0.16

            The ARB did not perform testing to confirm the emission test results

submitted by the applicant.       Emission test results submitted were below the

vehicle‘s baseline emission levels or within the allowable increases of 0.1

grams/mile or 10 percent on HC or NOx,           1.0 grams/mile or 15 percent on CO,       and

0.03 grams/mile or 15 percent on Particulates.

            In addition to their emissions evaluation Roush also performed a key

on engine off    (KOEO)   test and a key on engine running        (KOER}   test with the

vehicle in the baseline and modified configuration.              Hypermax used a new 1997

Ford F—350 truck with the 7.3L diesel engine to evaluate the affect of the

device on the vehicle‘s limited on—board diagnostic (OBD) II system.                The OBD

II system was introduced only on medium—duty diesels trucks in 1997.                No codes

were detected and the vehicle‘s monitors completed their check.                An incomplete

monitor would mean that the vehicle‘s computer had not been able to complete

its evaluation of the sensors associated with that monitor.                Therefore, based

on the test results and the OBD II checks,             the staff concludes that the

installation of the Diesel Controller will not have an adverse effect on

exhaust emissions on those applicable vehicles.

            Hypermax Engineering has submitted all the required information and

fulfilled the requirements for an exemption.
