State of California AIR RESOURCES BOARD EVALUATION OF NUTRONICS CORPORATION NU—CHARGE SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue E1 Monte, CA 91731 (This report has been reviewed by the staff of the California Air Resources Beard and approved for publication. 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 Nutronics Corporation of 700 Weaver Park Road, Longmont, CO 80501, has applied for an exemption from the prohibitions of Vehicle Code Section (VC) 27156 for the Nu—Charge system. The Nu—Charge system is an electronic control unit which controls the alternator operation by disconnecting the alternator during acceleration or high speed cruising, but reconnecting the alternator when either the accelerator pedal is released or the battery voltage falls below a specified level. The applicant intends to market the device for 1989 and older model—year vehicles equipped with 12—volt charging systems. Based on staff‘s engineering evaluation and results of tests performed by the Automobile Club of Southern California, the Nu—Charge system will have no adverse effect on emissions of the vehicles for which the exemption is requested. The staff recommends that Nutronics be granted a VC 27156 exemption for the Nu—Charge system as requested and that Executive Order D—198 be issued.

EVALUATION OF NUTRONICS CORPORATION NU—CHARGE SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE I. INTROBUCTION Nutronics Corporation of 700 Weaver Park Road, Longmont, CO 80501, has applied for a VC 27156 exemption in accordance with Section 2222, Title 13 of .the California Administrative Code to market the Nu—Charge system for 1989 and older model—year vehicles equipped with a 12—volt charging system. The Nu— Charge system decreases engine load by disconnecting the alternator during inefficient operating regimes, but reconnecting the alternator when either the accelerator pedal is released or the battery voltage falls below a specified level. In theory, removing the alternator output while the engine is under load will reduce engine drag and improve fue] economy. II. CONCLUSIONS The applicant has submitted all the required information. Based on data from tests performed by the Automobile Club of Southern California and an engineering evaluation of the Nu—Charge device, the staff concludes that the device will have no adverse effect on emissions. III. RECOMMENDATION The staff recommends the exemption be granted to Nutronics Corporation as requested and that Executive Order No. D—198 permitting the advertisement, sales and installation of the Nu—Charge system be issued.

IV. NU—CHARGE SYSTEM CR ON AND OPERATIO The Nu—Charge system is a 4 by 3 by 2 inch electronic control unit, weighing about 9 ounces, that is wired into a vehicle‘s charging system and connected to a manifold vacuum source. Vacuum is used to signal this unit when to turn the alternator on or off. A red LED light indicates when the alternator is charging (LED light on} or not charging (LED light off). The purpose of the Nutronics Nu—Charge system is to reduce parasitic losses caused by alternato} loads during inefficient operating regimes. The Nu—Charge electrically disables the alternator during acceleration or high speed cruising, but reconnects the alternator when the accelerator pedal is released or when the battery voltage falls below a specified level. During alternator disconnect the vehicle runs on electricity from the battery. In normal city driving, deceleration is adequate to keep the battery fully charged. The Nu—Charge system is designed to prevent battery discharge to the point where it will affect engine starting. V. DISCUSSION Nutronics submitted all the required information for obtaining a VC 27156 exemption for the Nu—Charge system. Emission tests were performed on four vehicles by the Automobile Club of Southern California. There were two baseline and two device tests performed on the Buick Skyhawk and the Subaru GL, while three baseline and three device tests were performed on the Ford LTD and the Mercury Sable. The results of the tests are shown in Appendix A. The tests showed that all four vehicles did not increase carbon monoXxide (C0) or oxides of nitrogen (NOx) emissions. However, for the hydrocarbon (HC) _3—

emissions, the 1988 Mercury Sable failed to meet the HC emission criteria (10% increase from baseline} by an 11.4% increase from the baseline. This is because HC emissions data from test #2, as shown in Appendix B, were not consistent with the results from other tests. HC emissions under tests #1 and #3 showed a negligible change from the baseline when tested with the device (—2.3%, and 0%, respectively), while that under test #2 showed a significant increase (33%). Test results under test #2 is also counter to the trend of no change or slight decrease in HC emissions exhibited by the other vehicles tested with the device installed. Based on these comparisons, data from test #2 was omitted resulting to an average change of 0% which is within the specified criteria. Emission data from the four vehicles tested by the Automobile Club of Southern California has demonstrated that use of the Nu—Charge system will not cause vehicle emissions to increase significantly. Engineering evaluation conducted by the ARB staff also supports the test results. Thus, confirmatory testing by the ARB is unnecessary. Based on the submitted data, the staff believes that the device does not viclate the prohibitions in California Vehicle Code Section 27156. The staff recommends that Nutronics be granted a VC 27156 exemption for the Nu—Charge system as requested and that Executive Order D—198 be issued.
