                                  SUMMARY



     Advanced Turbo Systems, Inc. {ATS) has requested an update to Executive

Order D—171—4, which currently exempts their turbocharger kit Model No. ATS

6.9L/7.3L for 1983—1987 model—year Ford Motor Company heavy—duty vehicles

powered by a 6.9 liter Navistar international heavy—duty diesel engine and

1988—89 model—year Ford heavy—duty vehicles powered by 5 7.3 liter Navistar

heavy—duty diesel engine.   Applicant has requested that the exemption be

updated to include the 1990 & 1991 model—year Ford heavy—duty vehicles

powered by a 7.3 liter Navistar heavy—duty diese! engine.



     Based on the fact that (1) 1989 emissions related equipment has been

carried over to the 1990—91 model—year versions of the 7.3 liter Navistar

heavy—duty diesel engine and (2) no changes to the retrofit turbocharger kit

Model No. ATS 6.9L/7.3L have been made for applications to the 1990 & 1991

model—year Ford vehicles powered by a 7.3 liter Navistar heavy—duty diesel

engine, the staff believes that the add—on turbocharger kit will have no

adverse emissions effect on the engine for which the exemption update is

requested.



     The staff recommends that ATS be granted an update as requested and

that Executive Order D—171—5 be issued.

       SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                        CALIFORNIA CODE OF REGULATIONS


I.            NTRODBU

       Advanced Turbo Systems, Inc. (ATS) of 5919 South 350 West, Murray, UT

84107, has requested an update to the existing Air Resources Board Executive

Order (E.0.) D—171—4 dated December 21, 1988.    E.0. D—171—4 exempted the ATS

turbocharger kit Model No. ATS 6.9L/7.3L from the prohibitions in Vehicle

Code Section 27156 for 1983—1987 model—year Ford heavy—duty vehicles powered

by a 6.9 liter Navistar heavy—duty diesel engine and the 1988—89 model—year

Ford heavy—duty vehicles powered by a 7.3 liter Navistar heavy—duty diesel

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

include the 1990 & 1991 model—year Ford heavy—duty vehicles with a 7.3 liter

Navistar heavy—duty diesel engine.

II.          CONCLUSIONS
       Based on the fact that (1) 1989 emissions related equipment has been

carried over to the 1990—91 model—year versions of the 7.3 liter Navistar

heavy—duty diesel engine and (2) no changes to the retrofit turbocharger Kit

Model No. ATS 6.9L/7.3L have been made for applications to the 1990 & 1991

model—year Ford vehicles powered by a 7.3 liter Navistar heavy—duty diesel

engine, the staff believes that the add—on turbocharger kit will have no

adversé emissions effect on the engine for which the exemption update is

requested.

III.         RECOMMENDATIOQN
       The staff recommends that ATS be granted an update as requested, and

that E.0. D—171—5 be issued.


iv.          KIT_DESCRIPTION
       The purpose of the ATS turbocharger kit is to increase the power output

of the engine by increasing its volumetric efficiency.     This is accomplished

by compressing the intake charge to pressures above that of the atmosphere.

The increase in pressure allows a greater charge density to enter the

combustion chamber, providing more oxygen for combustion.     The maximum fuel

delivery is slightly increased in order to maintain proper air—fuel ratios

with the increased air flow from the turbocharger when it is providing

positive manifold pressure (boost),

       The major components of the kit include a 0.96 A/R ratio Rotomaster

(Air Research) Model No. TO48, custom intake and exhaust tubing, air cleaner

assembly, brackets, hoses and the hardware necessary to complete the

installation.    The QOEM crankcase depression regulator is removed and

replaced with tubing and fittings with a 0.375 inch orifice supplied in the

kit.    A complete air cleaner assembly is supplied with the system to replace

the stock air cleaner assembly.    No other emission—related components are

removed or disconnected when the turbocharger kit is installed.

       Maximum positive manifold pressure is limited to 12 psi by the size of

the turbine and the compressor.    The maximum engine speed is requlated by

the OEM fuel injection governor which is not modified by the installation of

the kit.    Therefore, by controlling maximum engine speed, maximum turbine

speed and the corresponding boost pressure are also controlled.

Y¥.          DISCUSSION
       ATS add—on turbocharger kit Model No. ATS 6.9L/7.3L is designed for

installation on 1983—1987 model—year Ford vehicles powered by a 6.9 liter

                                      —3—


Navistar heavy—duty diesel engine and 1988—1989 model year Ford vehicles

powered by a 7.3 liter Navistar heavy—duty diesel engine.    The exemption was

granted based on test data from comparative exhaust emission tests and back—

to—back crankcase pressure tests performed for exempting the kit which

showed no reduction in the effectiveness of the vehicle‘s pollution control

system.

     The applicant is making available the add—on turbocharger kit Model No.

ATS 6.9L/7.3L for the 1990 & 1991 model—year Ford vehicles powered by a 7.3

liter Navistar heavy—duty diesel engine.   The applicant claims that no

modifications to the kit are needed in order to be compatible with the 1990

& 1991 models.   A request that the exemption be updated to include 1990 &

1991 model—year vehicles has been made by the applicant.

     In response to the applicant‘s request, the staff compared the engine

design of the 1990 and 1991 model—year Ford vehicles powered by a 7.3 liter

Navistar heavy—duty diesel engine to vehicle models currently covered by the

exemption.   Certification documents indicate that emissions equipment on

the 1989 model have been carried over to the     1990 & 1991 model—year

versions of the 7.3 liter Navistar heavy—duty diesel engine.     Also no

changes to the retrofit turbocharger kit Model No. ATS 6.9L/7.3L have been

made for applications to the 1990 & 1991 model—year Ford vehicles powered by

a 7.3 liter Navistar heavy—duty diesel engine.     Based on these facts, no

additional testing was required or performed for updating the exemption as

requested.
