                                 SUMMARY



      BAE Turbosystems of 3032 Kashiwa Street, Torrance, CA 90505, has

requested by letter dated December 14, 1982, an update to the existing

Air Resources Board‘s Executive Order (E.0.) No. D—97—12.     The applicant

requested that their add—on turbocharger kit No. 3—0012 be also exempted

from the prohibitions in Vehicle Code (V.C.) Section 27156 for the 1983

model—year BMW 5331, 633i, and 7331 model vehicles powered by a 195.9

cubic inch displacement (CID) six—cylinder gasoline engine.

      Based on the previous comparative exhaust emissions tests performed
on 1981 and 1982 model—year BMW 633i models and the fact that the engines

used in the 1983 model—year BMW 5331, 633i, and 733i model vehicles are

carry—overs (identical engine design} from the 1981 and 1982 models, the
staff concludes that the kit will not adversely affect exhaust emissions

from the 1983 BMW 533i, 6331, and 7331 models.

      The staff recommends that BAE Turbosystems be granted their update

request to include the 1983 model—year BMW 5331, 633i, and 7331 model

vehicles in the exemption of their add—on turbocharger kit No. 3—0012.

The staff recommends that Executive Order No. D—97—16 be adopted.

EVALUATION OF THE BAE TURBOCHARGER KIT NO. 3—0012 FOR EXEMPTION FROM THE
PROHIBITIONS IN VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION
2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE.



I.     INTRODUCTION

       BAE Turbosystems of 3032 Kashiwa Street, Torrance, CA 90505, has

requested by letter dated December 14, 1982, an update to the existing

Air Resources Board‘s Executive Order (E.0.) No. D—97—12.     The applicant

requested that their add—on turbocharger kit No. 3—0012 be also exempted

from the prohibitions in Vehicle Code (¥.C.) Section 27156 for the 1983
model—year BMW 533i, 633i, and 7331 model vehicles powered by a 195.9

cubic inch displacement (CID) six—cylinder gasoline engine.

II.    CONCLUSION

       Based on the previous comparative exhaust emissions tests performed
on 1981 and 1982 model—year BMW 633i models and the fact that the engines

used in the 1983 model—year BMW 533i, 633i, and 7331 model vehicles are

carry—overs {identical engine design) from the 1981 and 1982 models, the
staff concludes that the kit will not adversely affect exhaust emissions

from the 1983 BMW 533i, 6331, and 733i models.

III.   RECOMMENDATION

       The staff recommends that BAE Turbosystems be granted their update

request to include the 1983 model—year BMW 533i, 6331i, and 7331 model

vehicles in the exemption of their add—on turbocharger kit No. 3—0012.

The staff recommends that Executive Order No. D—97—16 be adopted.


IV.     TURBOCHARGER KIT DESCRIPTION AND OPERATION
        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 No. 3—0012 are a

turbocharger {with an A/R ratio of 1.0), 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 Tinked

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

the L—Jectronic fue!l 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

lTine 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 Timited 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 Tink to the oxygen sensor, temperature sensor, and throttle

valve switch.   When 2 psig is sensed by the control, the throttle vaive

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 fue! enrichment is provided by the BAE boost pressure

controlled fue! 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 Tine 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 retard mechanism of the distributor.
      No modifications to the OEM tune—up specifications are required

when the turbocharger kit is installed.    AlTI 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.


V.      DISCUSSION

        BAE turbocharger kit No. 3—0000W1 applicable to 1980 and 1981 model.
year BMW 6331 and 733i model vehicles powered by a 195.9 CID six—cylinder

gasoline engine was granted an exemption (E.0. No. D—97—7) on October 7,

1981.     The exemption was granted on the basis that the effectiveness
of the vehicle‘s pollution control system was not reduced.     Evaluation

consisted of comparative (without and with the kit installed on a test

vehicle) chassis dynamometer CVS—75 and HFET tests at normal and multiple

dynamometer road loading.

        Turbocharger kit No. 3—0000W1 was modified to accommodate the

engines in the 1982 models.     The modified kit, kit No. 3—0012, has

identical components, except for the discharge pipe (pipe for routing

intake air from the turbocharger compressor outlet into the intake
plenum).    Although the discharger pipes are bent differently, the kits

are identical in operation and performance.

        The 1982 model—year BMW 6331 and 7331 model vehicles have a

higher nominal compression ratio (8.8:1 compared to 8.0:1).     In order

for the applicant to demonstrate that the kit will not adversely affect

the exhaust emissions from the 1982 BMW models, the applicant performed

comparative exhaust emisstons tests on a 1982 model.    Since the

comparative tests indicated that the exhaust emissions from the 1982

mode! was not adversely affected by the installation of the add—on

turbocharger kit, an exemption was granted for kit No. 3—0012.
        The applicant is making available kit No. 3—0012 for the 1983

models.    The applicant has requested that the exemption be updated to

include the 1983 models.


      In response to the request, the staff compared the engine design of

both 1982 and 1983 modelT—years.     Since the engines in the 1983 models are

identically designed as the 1982 engines, the staff is of the opinton

that the 1983 vehicles will have the same degree of performance/emissions
impact as in the 1982 models.      Because the test data on a 1982 test

vehicle showed that the vehicle‘s emissions were not adversely affected

when the turbocharger kit was installed, the kit will have no adverse

effect on the 1983 models either.     No additional testing was required or

performed.
