This Executive Order does not constitute any opinion as to the effect that the use of this device may have on any warranty either expressed or implied by the vehicle manufacturer. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OFENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—PCLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF THE BAE TURBOCHARGER KIT NO. 3—0000W1. No claim of any kind, such as "Approved by Air Resources Board", may be made with respect to the action taken herein in any advertising or other oral or written communication.

BAE EXECUTIVE ORDER D—97—7 (Page 2 of 2?) Section 17500 of the Business and Professions Code makes untrue or misleading advertising unlawful, and Section 17534 makes violation punishable as a misdemeanor. Section 43644 of the Health and Safety Code provides as follows: "43644. (a) No person shall install, sell, offer for sale, or advertise, or, except in an application to the state board for certification of a device, represent, any device as a motor vehicle pollution control device for use on any used motor vehicle unless that device has been certified by the state board. No person shall sell, offer for sale, advertise, or represent any motor vehicle pollution control device as a certified device which, in fact, is not a certified device. Any violation of this subdivision is a misdemeanor ." Any apparent violation of the conditions of this Executive Order will be submitted to the Attorney General of California for such action as he deems advisable.

State of California AIR RESOURCES BOARD Staff Report October 7, 1981 Evaluation of the BAE Turbocharger Kit No. 3—0000W1 for Compliance with the Requirements of Section 27156 of the Vehicle Code I. INTRODUCTION BAE, of 3032 Kashiwa Street, Torrance, California 90505, has applied for exemption of a turbocharger kit from the prohibitions of Section 27156 of the Vehicle Code (V.C.). The kit, turbocharger kit number 3—0000W1, is intended for 1980 and 1981 model—year BMW 6331 and 733i models having a 195.9 cubic inch displacement (CID) six—cylinder gasoline engine. BAE has submitted comparative emissions data from back—to—back cold—start CVS—75 and hot—start HFET tests on a 1981 BMW 633i model with 5—speed manual transmission conducted at Olson Engineering, Inc., in Huntington Beach, California. Confirmatory tests were conducted on the same vehicle at the Air Resources Board (ARB) laboratory in El Monte, California. II. TURBOCHARGER KIT DESCRIPTION The purpose of turbocharging is to increase the volumetric efficiency of an engine by forcing more air into an engine than it would take in under naturally aspirated conditions. The major components of the BAE turbocharger kit number 3—0000W1 are a turbocharger (Rajay Model No. 300E or Airesearch Model No. TAOQ4 H3), a

replacement BAE exhaust manifold, a pressure control wastegate, a fuel enrichment control, and a boost pressure controlled fuel regulator. The components are packaged with installation hardware and installation instructions and sold as a kit. The original equipment manufacturer (OEM) exhaust manifold is replaced by a BAE manifold. The turbine inlet mounts directly to the replacement manifold. The turbine, driven by exhaust gases, is linked to the compressor by a solid shaft. Intake air from the air box, of the L—Jectronic fuel injection system, is routed to the compressor. Compressed air is then piped to the intake plenum through the discharge pipe. The lubrication of the turbocharger is provided by a steel—braided line from the oil filter adapter located at the engine block to the turbocharger bearing housing. Oil from the turbocharger is returned to the engine block. Maximum positive manifold pressure (boost) is limited to 7 psig by a wastegate mounted on the exhaust manifold. The wastegate is preset to dump excess exhaust gases when intake manifold pressure reaches 7 psig. The kit also contains a fuel enrichment control. The control has a vacuum line which tees to the left side of the intake plenum for sensing positive boost conditions. Also attached to the control are three sets of wire which lTink to the oxygen sensor, temperature sensor, and throttle valve switch. When 2 psig is sensed by the control, the throttle valve opens allowing more intake air and fuel into the combustion chamber. Upon sensing 3.5 psig of boost pressure, the oxygen and temperature sensors are deactivated to signal the computer (in the car) to run in the rich mode as in cold—start/warm—up conditions.

Additional fuel enrichment is provided by the BAE boost pressure controlled fuel regulator during high boost pressures. The regulator is positioned in the fuel return line between the OEM fuel pressure . regulator and the fuel tank. During high boost conditions, the BAE regulator blocks the return line and increases the pressure differential across the injectors, thus forcing more fuel to be injected. A vacuum delay valve is used to control NOx emissions and to suppress detonation. The valve is installed in the vacuum line prior to the vacuum return mechanism of the distributor. No modifications to the OEM tune—up specifications are required when the turbocharger kit is installed. All OEM emission controls are left intact. BAE recommends that premium non—leaded fuel be used with the turbocharger kit, but regular non—leaded fuel is compatible. III. TEST PROGRAM A 1981 BMW 633i mode?! with a six—cylinder engine and 5—speed manual transmission was used for testing. The certification test weight is 3875 lbs. The road load horsepower (RLHP) used in the testing was 12.6 horsepowér at 50 mph. Testing at the ARB laboratory consisted of cold—start CVS—75 and hot—start HFET tests at normal RLHP to determine exhaust emissions of the unmodified (baseline) and turbocharged (device) configurations for comparison.

IV. TEST DATA The applicant‘s and ARB‘s emissions test data are shown in Table 1 and Table 2, respectively: Table 1 Applicant‘s Emissions Test Data Fuel Exhaust Emissions (g/mi) Economy Test HC co nox _(mpg) Baseline CVS—75 0.37 2.23 0.53 15.2 Device CVS—75 0.28 2.21 0.35 14.0 Baseline HFET 0.14 1.30 0.23 21.3 Device HFET 0.07 0.44 0.47 22.0 Table 2 ARB‘s Emissions Test Data Fuel Exhaust Emissions (g/mi) Economy Test HC co Nox _{(mpg) Baseline CVS—75 0. 40 2.42 0.72 14.8 Device CVS—75 0.35 2.69 0.39 14.4 Baseline HFET 0.18 1.04 0.48 23.0 Device HFET 0.11 0.60 0.48 23.4 v. DISCUSSION The two sets of CVS—75 and HFET comparative emissions tests show that the turbocharger kit, when installed, will not adversely affect the vehicle‘s exhaust emissions.

VI. CONCLUSION AND RECOMMENDATIONS Comparative emissions tests indicate that the BAE turbocharger kit number 3—0000W1 will not adversely affect exhaust emissions when installed in accordance with the manufacturer‘s instructions. The staff recommends that BAE be granted an exemption from the prohibitions of ¥.C. Section 27156 for this kit for 1980 and 1981 model—years BMW 633i and 7331 models having a 195.9 CID six—cylinder engine. The staff recommends that Executive Order No. D—97—7 be adopted.
