                                    summary

      BAE Turbosystems has applied for exemption from the prohibitions in

Vehicle Code Section 27156 for an EGR restrictor plate.    The restrictor plate,

BAE part number 31005, has been approved for installation on 1983 model—year

Executive Coach Builders, Inc.‘s Lincoln Town Car 21" Limousine powered by a

Ford Motor Company 302 cubic inch displacement fuel injected engine under Air

Resources Board‘s Executive Order A—248.   BAE requested that the restrictor

plate also be approved for installation on 1981 and 1982 California—certified

Allen Coach Works, Inc.‘s Lincoin Timousines powered by a Ford Motor Company

302 cubic inch displacement fuel injected engine, provided that the

limousine‘s curb weight will not exceed 4,980 Tbs. (certification test weight

of 5,500 Tbs.) and that the lTimousine‘s body was not elongated more than 40

inches.

      BAE has submitted data from cold—start CVS—75 emission tests.    The tests

were performed on a 1983 Lincolin Town Car limousine.   Comparative tests

consisted of baseline with the Timousine in the stock configuration (no EGR

restrictor plate), and modification (with the EGR restrictor plate installed).
      Emission test results submitted by BAE indicate that the restrictor

plate, as designed and installed on the test vehicle, will not have an adversé

effect on exhaust emissions from vehicles for which exemption is requested.
      Based on the above, the staff recommends that BAE Turbosystems be

granted an exemption as requested and the Executive Order D—97—22 be issued.

EVALUATION OF BAE TURBOSYSTEMS‘ EGR RESTRICTOR PLATE FOR EXEMPTION FROM THE
PROHIBITIONS IN VEKICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222,
TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE



I.     INTRODUCTION

       BAE Turbosystems, of 3032 Kashiwa Street, Torrance, California 90505,

has applied for exemption from the prohibitions in Vehicle Code Section 27156

for an EGR restrictor plate.   The restrictor plate, BAE part number 31005, has

been approved under Air Resources Board Executive Order A—248 for installation
on 1983 model—year Executive Coach Builders, Inc.‘s Lincoin Town Car 21"

Timousine with a curb weight of 4,980 1bs. and powered by a Ford Motor Company

302 cubic inch displacement fuel injected engine.   BAE requested that the

restrictor plate also be approved for installation on 1981 and 1982

California—certified Lincoln limousines manufact´Čüred by Allen Coach Works, Inc.

       BAE has submitted data from cold—start CVS—75 emission tests.   The tests

were performed by Fairway Environmental Engineering in Torrance, California,

on a 1983 Lincoln Town Car Timousine.   Testing consisted of baseline with the

limousine in the stock configuration ({no EGR restrictor plate), and

modification (with the EGR restrictor plate installed).

II.    CONCLUSION

       Emission test results submitted by BAE indicate that the EGR restrictor

plate, as designed and installed on the test vehicle, will not have an adverse

effect on exhaust emissions from vehicles for which exemption is requested.

III.   RECOMMENDATIONS

       Based on the above conclusion, the staff recommends that BAE

Turbosystems be granted an exemption as requested and that Executive Order

D—97—22 be issued.


IV.      EGR RESTRICTOR PLATE DESCRIPTION AND OPERATION

         BAE‘s EGR restrictor plate is designed to be inserted between the

original equipment manufacturer (OEM) EGR valve base and intake manifold.

The restrictor plate is manufactured of 1/4 inch steel stock and contains

four holes:     two for mounting screws and two for exhaust gas flow.   The

diameter of the intake hole on the plate (for flowing gases into the EGR

valve) is of identical size as the EGR valve (3/4 inch), however, the
effective outlet diameter of the EGR valve body for exhaust gas

recirculation is reduced from 3/4 inch to 3/8 inch (50%) by the restrictor
plate.     The effective outlet flow area is reduced from 0.44 square inch

to O.11 square inch (75%) by the smaller diameter exhaust hole.

         The restrictor plate, according to BAE, will reduce EGR flow rate
at any valve opening and vacuum signal to the valve compared to the OEM

design of the vaIve.     This reduction in EGR flow is needed, according to

BAE, in order not to increase CO emissions due to vehicle body eTongation

and increase in vehicle weight when converting the sedan vehicle into a

limousine.
V.       EVALUATION

         A 1983 California—certified limousine converted by Executive Coach

Builders, Inc. and powered by a Ford Motor Company 302 CID fuel injected

engine was used for the evaluation of the restrictor plate.     The

certification dynamometer test parameters of 5,500 Tbs. and 14.5 hp were
used.    Comparative tests were run with the Timousine in the stock (no EGR

restrictor plate}), and in the modified ({with the EGR restrictor plate
installed) configurations.    A summary of the test results is tabulated in

the Appendices.


VI.   DISCUSSION

      The test results indicate that HC and CO emissions are reduced with the

installation of the EGR restrictor plate, while NOx emissions remain

unchanged.   This reduction in HC and CO emissions can be attributed to reduced

throttle angle required with the EGR restrictor plate, in order to maintain

any speed, compared to the vehicle without the restrictor plate; thus leaning

the fuel charge and reducing HC and CO emissions.

      Since the engines, manufactured by Ford Motor Company, used in the 1983

Executive Coach Builders, Inc.‘s limousines are carry—overs {identical engine

designs) as the ones used in the 1981 and 1982 Allen Coach Works, Inc.‘s

limousines, the staff is of the opinion that the BAE EGR restrictor plate will
have the same degree of performance/emissions impact on the 1981 and 1982

Allen Coach Works, Inc.‘s limousines as on the 1983 Executive Coach Builders,

Inc.‘s Timousines.
