State of California AIR RESOURCES BOARD EVALUATION OF THE GOODMAN SYSTEM COMPANY, INC.‘S "GOODMAN SYSTEM" WATER INJECTOR FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 April, 1983

Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

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.

State of California AIR RESOURCES BOARD 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. Table 1 Applicant‘s Test Vehicle/Descriptions Description Vehicle 1 Vehicle 2 Year 1983 1983 Make Ford Mercury Mode1 Escort Zephyr Engine Size 1.6L, I—4 3.3L, 1—6 Emission Control AIR, EGR, TWC AIR, EGR, TWC Carburetor Type 2¥ V Odometer Mileage 2. 9K 4. 8K Table 2 Applicant‘s Comparative CVS—75 Emission Results Exhaust Emissions (gm/mi) Fuel Mileage (MPG) VYehicle HC C8 NOx Urban & Highway Combined #1 BaseTine 0.6 9.9 0.9 25.2 #1 Device 0.6 10.6 0.8 24.3 #2 Baseline 0.6 4.1 0.5 19.5 #2 Device 0.5 3.2 0.6 19.1 1983 Std. 0.41 7.0 0.7

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.
