IT IS ORDERED AND RESOLYED: That the installation of the turbocharger
kit model No. TO4G M2 manufactured by BAE of 3032 Kashiwa Street, Torrance,
California 90503, has been found not to reduce the effectiveness of
required motor vehicle poliution control devices and, therefore, is exempt
from the prohibitions of Section 27156 of the Vehicle Code for 1981 model
year Airstream 28 foot motorhomes having an Isuzu QD 145 six—cylinder diesel
engine and automatic transmission.

This Executive Order is valid provided that installation instructions
for this device will not recommend tuning the vehicle to specifications
different from those submitted by the device manufacturer.

Changes made to the design or operating conditions of the device, as
exempted by the Air Resources Board, that adversely affect the performance
of a vehicle‘s pollution control system shall invalidate this Executive
Order.

Marketing of this device using an identification other than that shown
in this Executive Order or marketing of this device for an application
other than those listed in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board.     Exemption of a
kit shall not be construed as an exemption to sell, offer for sale or
advertise any component of a kit as an individual device.

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 OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY
ALLEGED BENEFITS OF THE BAE TURBOCHARGER KIT, KIT MODEL NO. TO4B M2.

                              June 5, 1981

Evaluation of the BAE Turbocharger Kit Model No. TO4B M2 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 model No. TO4B M2,

is intended for 1981 model year Airstream 28 foot motorhomes having an

Isuzu QD 145 six—cylinder diesel engine and automatic transmission.

      BAE has submitted comparative emission data from back—to—back steady

state exhaust emissions tests conducted on an Airstream motorhome at the

company‘s own emission laboratory.    Confirmatory tests were conducted on

the same motorhome at the Air Resources Board‘s (ARB) Haagen—Smit

Laboratory in El Monte, California.

II.   TURBOCHARGER KIT DESCRIPTION

      The BAE turbocharger kit consists of an AiResearch turbocharger, an

exhaust manifold to turbocharger adaptor, and an intake pipe.    The components

are packaged with installation hardware to complete the kit.

      The exhaust manifold to turbo adaptor is installed on the OEM exhaust

manifold located on the driver‘s side of the engine..   The turbine inlet of

the turbocharger mounts directly to the adaptor.    The turbine, driven by

exhaust gases, is linked to the compressor by a solid shaft.    Compressed

incoming air is routed to the intake manifold through the BAE intake

pipe mounted transversely over the engine.


       Maximum positive manifold pressure is limited to 13 psig by the size

 of (and exhaust flow through) the turbine housing.     No wastegate or other

 active boost limiting device is used.

       The cooling of the turbocharger is achieved by direct fan air from

 engine and lubricating oil passing through the unit.     The oil is piped

 from the filtered main oil galley to the turbocharger bearing housing.

 Oil from the turbocharger is returned to the oil pan.

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

 the turbocharger kit is installed.

 III. TEST PROGRAM
       A 1981 Airstream 28 foot motorhome with an Isuzu QD 145 six—cylinder

 diesel engine and automatic transmission was used for testing.     The test

v weight for the motorhome is 14,500 lbs.    The frontal area road load horsepower

 (RLHP) used in the testing was 36 horsepower at 50 mph.

       Back—to—back steady state tests were conducted on the test motorhome

 at the following points:

       1)   idle
       2)   60, 50, 40, 20 mph at 2 times RLHP

       3)   idle

       4)   60, 50, 40, 20 mph at 1 times RLHP

 IV.   APPLICANT TEST DATA
       The applicant‘s exhaust emissions test data in Table 1 was generated

 at the company‘s own emission laboratory.

(Z)HC as carbon measured by an HFID.


VI.    DISCUSSION

       The app]icant‘é reported exhaust HC emission data in Table 1 were

calculated from measured HC values.      The applicant‘s laboratory used

a general (not heated) Flame lonization Detector (FID) for exhaust

hydrocarbon determination.      An experimental factor of 3.5 was used by

the applicant to convert the measured FID values to Heated—FID values.

HC data reported by the ARB laboratory were obtained using a HFID.

       The two (2) sets of laboratory data (Tables 1 and 2) show that there

are some changes in emissions due to the installation of the turbocharger

kit.    The changes, however, are within test variability and are considered

to be insignificant.

VII. CONCLUSION AND RECOMMENDATIONS

       Comparative chassis dynamometer tests indicate the the BAE turbocharger

kit model No. TO4B M2 will not significantly 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 V. C. Section 27156 for this kit for 1981 modé] year Airstream 28 foot

motorhomes having an Isuzu QD 145 six—cylinder diesel engine and automatic

transmission.       The staff recommends that Executive Order No. D—97—2 be

adopted.
