                                      SUMMARY




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

Order D—171—2, which 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 model—year Ford

heavy—duty vehicles powered by a 7.3      liter Navistar heavy—duty diesel engine.

They have requested that the exemption be updated to include the 1989 mode!—

year Ford heavy—duty vehicles powered by a 7.3 liter Navistar heavy—duty diese!

engine.

          Based on the fact that (1) there is no emissions—related difference

between the 1988 and the 1989 model—year versions of the 7.3 liter Navistar

heavy—duty diesel engine and (2) no emissions—related variations to the

retrofit turbocharger kit Model No. ATS 6.9L/7.3L have been made for

applicatlon to the 1989 model—year version of the 7.3 liter Ford/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—4 be issued.

turbocharger kit Mode! 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 model—year Ford heavyj

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 1989

model—year Ford heavy—duty vehicles with a 7.3 liter Navistar heavy—duty diese!

engine.

          Based on the fact that (1) there is no emissions—related difference

between the 1988 and the 1989 model—year versions of the 7.3 liter Navistar

heavy—duty diese! engine and (2) no emissions—related variations to the

retrofit turbocharger kit Mode! No. ATS 6.9L/7.3L have been made for

application to the 1989 model—year version of the 7.3 liter Ford/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 E.0. D—171—4 be Issued.


IV.    TURBOCHARGER KIT DESCRIPTION AND           OPERATION

       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

increased pressure allows a greater charge density to enter the combustion

chamber providing more oxygen for combustion.           The maximum fuel delivery      is

stightly 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

(AirResearch) Mode! No. TO48, custom intake and exhaust tubing, air cleaner

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

installation.     The OEM crankcase depression regulator           is removed and replaced

with tubing, fittings with a 0.375" orifice suppl]ed 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 regulated by the

OEM fue!   Injection governor which is not modified by the            installation of the

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

corresponding boost pressure are also controlled.

v.     D        LQN

       ATS add—on turbocharger kit Mode! No. ATS 6.9L/7.3L              is designed for

Installation on 1983—1987 modei—year Ford vehicles powered by a 6.9 l|iter .

Navistar heavy—duty diesel engine and 1988 mode! year Ford vehicles powered by

a 7.3 liter Navistar heavy—duty diesel engine.               The exemption was granted on

                                            —2—


the basis that the test data from comparative exhaust emission tests and back—

to—back crankcase pressure tests performed for exempting the kit showed no

reduction in the effectiveness of the vehicle‘s pollution control system.

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

ATS 6.9L/7.3L for the 1989 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 1989 models;      They

have requested that the exemption be updated to include these 1989 model—year

vehicies.

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

design of 1988 and 1989 mode!—year Ford vehicles powered by a 7.3 liter

Navistar heavy—duty diesel engine.    Certification documents   indicated that

there is no emissions—related difference between the 1988 and the 1989 mode!—

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

emissions—related varliations to the retrofit turbocharger kit Model No. ATS

6.9L/7.3L have been made for application to the 1989 model—year version of the

7.3 \iter Ford/Navistar heavy—duty dissel engine.    Based on these facts, no

additional   testing was required or performed for updating the exemption as

requested.
