                                    SUMMARY




      The Goodman System Company, Inc. has requested exemption from the

prohibitions of Vehicle Code Section 27156 for the Goodman System, a water

injector device.   Two previous applications were denied because of increased

emissions from test vehicles with the use of the device.   The manufacturer
then modified the design of the device twice.   The device in its present

configuration has shown, through comparative emission testing, no effect on

the operation and the performance of OEM emission controls.   The test data
also show no effect on fuel economy with the use of the device.

      The staff, therefore, recommends adoption of Executive Order D—129 since
no adverse emissions impact was found.

EVALUATION OF THE GOODMAN SYSTEM COMPANY, INC.‘S "GOODMAN SYSTEM" WATER
INJECTOR FOR EXEMPTION FROM THE PROHIBITIONS OF VEKHICLE CODE SECTION 27156

I.    INTRODUCTION

      The Goodman System Company, Inc. of New York, NY 10022 has applied for

an exemption from the prohibitions of Vehicle Code Section 27156 for an add—on
water injector device known as the "Goodman System".     Exemption is sought for

1983 and older model—year vehicles, except for the following:

          i} All diesel engines.

          ii} General Motors‘ variable displacement 8—6—4 engines.

      iiij Vehicles which are not normally equipped with an air injection pump.

          iv) Vehicles originally equipped with closed—1oop feedback carburetors.
      The Goodman System uses compressed air from the air injection pump

("smog pump") to spray water through a nozzle into the carburetor‘s air horn.
      Two early Goodman System models, the first and the second generation

model, caused adverse emission problems, and the exemption applications were
denied.    The current application for the third generation model was

accompanied with data from comparative exhaust emission tests of two 1983

model—year vehicles.

II.   CONCLUSIONS

      The submitted comparative exhaust emission data from the two 1983

model—year vehicles fllustrate no adverse emissions impact with the use of the

third generation Goodman System.    The data also shows that the fuel economy of

the test vehicles was not affected with the use of the device.


I1I.   RECOMMENDATION
       Since the device does not show an adverse emission effect, the staff
recommends that the third generation Goodman System be exenpted from the
prohibitions of Vehicle Code Section 27156 for the vehicles as requested.      The

staff recommends the adoption of Executive Order D—129.

IV.    SYSTEM DESCRIPTION AND EVALUATION

       A.     SYSTEM DESCRIPTION
              The "Goodman System" consists of a spray nozzle, a load sensor, an

air pump tap, a check vaive, a temperature switch, a water reservoir bag, and

connective tubings (See Figure 1.)
       The metal spray nozzle is connected to the air supply and water

reservoir.     It is installed in the air cleaner housing.   The crifice sizes of
the nozzle vary from 0.012" to 0.022" for use on different sizes of engines.

The load sensor is basically a bypass valve.     It directs air flow from the air

pump to the nozzle.     During high manifold vacuum engine operating modes, the
diaphragm in the valve is pulled down by the vacuum force allowing air to

escape to the atmosphere.     The load sensor is pre—adjusted (and sealed) by the

manufacturer to prevent excessive water injection during high vacuum modes.

The air pump tap i§ a plastic tee with a hose fitting protruding from its

center at a right angle.     It is simply installed by removing a small section

of the rubber pressure hose in the secondary air injection system and

inserting the tap in its place.     The tap is then secured by two screw clamps.

The temperature sensor/switch is installed in the air cleaner housing and

prevents the device from functioning until the underhood air temperature is

above 60°F.


      The third generation Goodman System includes a modification to the

device‘s air pump tap to reduce the delivery pressure and, therefore, the

amount of air to the load sensor.   The amount of water injection is expected

to be proportionally reduced.    The modification involved the removal of a
restriction in the tap so that the designed secondary air supply to the engine

will not be markedly changed.

      In operation, air, under pressure from the air pump, is supplied through
the load sensor to the spray nozzle located in the air cleaner housing

directly over the carburetor‘s air hbrn.    The flow of air creates a Tow

pressure area at the nozzle orifice allowing water to be drawn from the
reservoir.    As the water enters the air stream, it is atomized and the

air/water mixture is drawn into the carburetor and, subsequently, along with

the air/fuel mixture into the engine cylinders.    The load sensor is preset to

cut off the air supply {venting to atmosphere) to the nozzle during high

vacuum engine operation periods, thereby preventing water from being drawn

from the reservoir.

      The applicant claims that the system will deliver 10—12 percent water
{in the air/fuel mixture) during accelerations (Tow manifold vacuum), 3—5

percent water during cruise conditions (moderate manifold vacuum), and no
water during idle and decelerations (high manifold vacuum).

      B.     SYSTEM EVALUATION

             In order for the applicant to demonstrate compliance of the third

generation device with the "no emission increase" requirements, two vehicles

were selected for testing.


         The applicant delivered the vehicles to the Southern California

Automobile Club‘s emission laboratory for comparative CVS—75 exhaust emissions

tests.     The test vehicles are described in Table 1, and the comparative

emission test results are shown in Table 2.

         The Air Resources Board did not perform confirmatory testing of the
third generation Goodman System.

V.       D1SCUSSION

     ‘   The applicant‘s comparative emission data were reviewed by the staff.
The differences in HC and NOx emission values between the paired

baseline/device tests were considered to be within the lTimits of test

variability; there were no measurable changes in HC and NOx emissions from the

baseline levels due to the use of the device.        The CO emissions changed

slightly; there was an increase for test vehicle No. 1 and there was a

decrease for test vehicle No. 2.        The increase for test vehicle No. 1 was

insignificant.

         It should be noted that both test vehicles exceeded at least one of the
applicable exhaust emission standards.        However, no obvious defects were found.
         Each of the vehicles tested has emission controls, which are sensitive

to any changes in engine operating parameters caused by the installation/use

of the device.        It is evident from the test resulTts that the device did not
affect the operation and the performance of these emission contfols.

         The applicant also performed testing with only the air pump tap

installed to demonstrate—that the amount of reduction in the secondary air

supply to the engine would not affect exhaust emissions.        The test data was

reviewed by staff, and no emissions changes were found.
