of a vehicle‘s pollution control system shall invalidate this Executive
Order.

                              July 1, 1981

Evaluation of the BAE Turbocharger Kit Model No. 2—0000—1 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 California Vehicle Code (V.C.).     The kit, turbocharger kit

model number 2—0000—1, is intended for 1981 model year BMW 3201 modeis

having a 107 CID four—cylinder engine.

      BAE has submitted comparative emissions data from back—to—back

cold—start CVS—75, hot—start HFET, and steady state exhaust emissions

tests on a 1981 BMW 3201 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.     The ARB

testing consisted of cold—start CVS—75 and hot—start HFET exhaust emissions

tests at normal road load horsepower.

II.   TURBOCHARGER KIT DESCRIPTION

      The purpose of turbocharging is to increase the volumetric efficiency

of an engine.   The major components of the BAE turbocharger kit are a

RaJay turbocharger model 300F, a replacement exhaust manifold, a

replacement intake plenum, an intake and a discharge pipe, and a positive

manifold pressure control wastegate.     The components are packaged with

installation hardware and instructions and sold as a kit (see Figure 1).


       The original equipment manufacturer (OEM) exhaust manifold is

replaced by a BAE manifold.     The turbine inlet mounts directly to the

replacement exhaust manifold.    The turbine, driven by exhaust gases, is

linked to the compressor by a solid shaft.     Intake air from the air box,

of the K—Jetronic System, is routed through the intake pipe to the

compressor.    Compressed air is then piped to the BAE replacement intake

plenum through the discharge pipe.

       The lubrication of the turbocharger is provided by a steel braided

line from the filtered engine oil galley to the turbocharger bearing

housing.    QOil from {he turbocharger is veturned to the oil pan.

       Maximum positive manifold pressure (boost) is limited to 5 psig

by a wastegate mounted on the exhaust manifold.    The wastegate is

preset to dump excess exhaust gases when intake manifold pressure reaches

5 psig, thus bypassing the turbine.

       No modifications to the OEM tune—up specifications are required when

the turbocharger kit is installed except for disconnecting the ignition

distributor vacuum advance unit and plugging it at the throttle body with

a plug supplied by BAE.    All other OEM emission controls remain intact.

111. TEST PROGRAM
       A 1981 BMW 320i model with a four—cylinder engine and 5—speed manual

transmission was used for testing.    The certification test weight is 2750

Ibs.    The road load horsepower (RLHP) used in the testing was 11.5

horsepower at 50 mph.

       Testing by the applicant consisted of cold start CVS—75, hot start

HFET and steady—state at normal RLHP to determine exhaust emissions of

the unmodified (baseline) and turbocharged (device) configurations for

comparison.    Confirmatory tests at the ARB laboratory consisted of cold

start CVS—75 and hot start HFET tests at normal RLHP.

VI.    DISCUSSION

       Results of the steady state tests indicate that there are no increases

in pollutants with the turbocharged vehicle over the baseline during all

modes of testing.

       The two (2) sets of valid CVS—75 and HFET comparative emissions tests

(Tables 1 and 3) show that the emissions of the test vehicle are slightly

changed due to the installation of the turbocharger kit.          The differences,

however, are considered to be within test variability and insignificant.

VII. CONCLUSION AND RECOMMENDATION

       Comparative emissions tests indicate that the BAE turbocharger kit

model number 2—0000—1 will not significantly affect emissions when installed

in accordance with the manufacturer‘s instructions.          The staff recommends

that BAE be granted an exemption from the prohibitions of V.C. Section 27156

for this kit for 1981 model year BMW 3201 models having a 107 CID four—cylinder

engine.    The staff recommends that Executive Order No. D—97—4 be adopted.
