State of California AIR RESQOURCES BOARD Staff Report September 17, 1980 Evaluation of Zemco, Inc. "Fuel Saver" Device 1. Introduction Zemco, Inc. 12907 Alcosta Blvd, San Ramon, CA. 94583, has submitted an application requesting an exemption from the prohibitions of Section 27156 of the California Vehicle Code for their "Fuel Saver" device. The device is designed for installation on all 1980 and older model—year vehicles except for the following: 1. Diesel powered vehicles 2. Vehicies which do not utilize electric engine starters {i.e. motorcycles and manual starters). II. System Description and Operation The Fuel Saver is an electronically controlled device which auto— matically stops and restarts the engine. This is accomplished by means of an electronic control unit and various sensors. The device does not function, by design, for approximately two minutes after initial engine starting. This allows the engine to warm—up. The control unit requires signals from two sensors for its operation. The first signal is received from the vehicle‘s brake system. When the operator appltes the foot brakes, an electrical signal from the brake light switch is routed to the Fuel Saver control unit. A second sensor, which is included in the device kit, detects the speed of the vehicle. This sensor is installed at the vehicle‘s drive shaft (see Figure 1).

Approximately two seconds after receiving signals from the brake light switch and the movement sensor, the control unit opens the ignition circuit to the cotl, thus stopping the engine. In restarting the engine, the operator simply presses the accelerator, which has been fitted with a micro switch. The micro switch signals the control unit to close the ignition relay and to activate the relay for the engine starting system. After the engine is restarted the device will not stop the engine again until the vehicle is moved severa]_feet. This is to prevent multiple restarts. The control unit is mounted in the passenger compartment (see Figure 2). It incorporates the following features: 1. On—Off switch. This allows the operator to activate or deactivate the unit by simply pressing the corresponding button. 2. A—digital display informing the operator of the quantity of fuel saved when the engine is turned off. 3. Five rocker switches on the back of the unit allow it to be matched to various vehicle applications. Switches 1 and 2 determine the number of cylinders and the engine size. Switch 3 determines if the digital display will register in gallons or liters. Switch 4 signals the unit whether or not to automatically disable when the engine is shut off. The applicant considered this.a safety feature but i@ only provides a way for the unit to remember the mode before the engine was shut off. Switch 5 determines how the engine will be restarted, either by the micro switch on the accelerator or by the absence of the signal when the brakes are released. The manufacturer recommends use of the accelerator restarting method. Switch 5 was added for certain manual transmission applications.

III. System Evaluation The applicant submitted CYS test data prepared by Olson Engineering in Huntington Beach, California to demonstrate that the device does not have an adverse effect on emissftons. Thectest vehicle is described in Table 1 and its emission results are given in Table 2. The percentage change from the baseline emissfons are given in parenthesis.

All three of the measured emissions were reduced and the fuel economy increased 8% with the device. The staff concluded that since the engine was shut—off during portions of the test cycle, fuel was not consumed and there were no exhaust emfssions. It should be noted that this test vehicle uses electronic controi1ed fuel injection which could be less susceptible to throttle position on restarts. The staff, therefore, requested the applicant to submit a device for confirmatory testing at the ARB‘s laboratory. When installing the device on the ARB‘s test vehicle, considerable problems were encountered. The device had design problems which resulted in failure of several modules. In order to save test time, temporary

modifications to the device were made to test its concept on a vehicle with a carburetor and standard points type ignition system. The emission results are listed in Table 4. The device emission results indicated little change in HC and NOx emissions. Although CO emissions increased 22%, the staff did not consider this type of emission increase significant due to the limits of test variability. During the ARB‘s confirmatory testing, the engine stoppage time was determined and is recorded in Table 7. This data revealed that the device stopped the engine 232.6 seconds or 9.4% of the total test time. The amount of time required to restart the engine was noted during the test cycle. All restarts, éifie}f ;he firsf one ét i30 séconfis; réqu{fed” less than one second. The first restart took approximately 3 seconds because the vehicle was not completely warmed—up. The test for determining fuel economy, the Highway Fuel Economy Test, was not used because it does not have stop and go driving portions. The design problems associated with the device resulted in changes to it. The relays for both the ignition and start solencids were removed from the module and re—installed in the engine compartment and improved designed wire connectors were used. These changes solved the design problems. The applicant, to demonstrate that the design changes soived the problems, conducted additional testing on a third vehicle. The emission results are listed in Table 6. The test vehicle demonstrated extremely high CO and HC emissions for the first serfies of tests (before repairs). A second series of tests (after repairs) was conducted but the HC emissions still exceeded the emission standard. Although the vehicle still showed signs that further repairs were needed the device emission results did demonstrate no significant emission increases when compared to the baseline test.

The second portion, (b) is 600 seconds without emission measurements The third portion, (c) is a repeat of the first 505 seconds of (a) with emission measurements

V. Conclusions and Recommendations The device was tested in three different designs. The concept proved that stopping and restarting the engine would not cause a signifi— cant emissfon fncrease and that fuel economy would benefit. Even though less fuel would be consumed, the device would cause additional wear on the engine‘s starting circuit. ©Individuals have been performing the same task without the use of the device by manually stopping and restarting the engine during stop and go traffic. Since the use of the device does not have adverse effect on emissions, the staff recommends that the Board grant Zemco, Inc. an exemption from the prohibitions of Section 27156 of the California Vehicle Code for their "Fuel Saver" device.
