Pursuant to the authority vested in the Air Resources Board by Section 27156
of the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and
39516 of the Health and Safety Code and Executive Order G—45—5;

IT IS ORDERED AND RESOLVED:   That the modification of 1975 through 1981 model
8VY—92TA and 1976 through 1981 model 6V¥—92ZTA General Motors Detroit Diesel
Allison Division heavy—duty diesel engines has been found not to reduce the

modification will consist of replacing the OEM cylinder lTiner, gear train for
blower drive gear, fuel injectors, blower, turbocharger, aftercooler, air
inlet housing, throttle delay check valve, camshaft, and piston rings with
corresponding parts utilized in 1982 California certified engines.      It is
hereby exempt from the prohibitions of Vehicle Code Section 27156.

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

Changes made to the design or operating conditions of the "CUE" package, 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 the "CUE" package using an identification other than that shown
in this Executive Order or marketing of the "CUE" package for an application
other than those Tisted in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board.

This Executive Order does not constitute any opinion as to the effect that the
use of the "CUE" package may have on any warranty either expressed or implied
by the vehicle manufacturer.

                                   Staff Report

                                   June 15, 1982
Evaluation of General Motors Corporation‘s "California Upgrade for Economy"
(CUE) Engine Modification in Accordance with Section 2222, Title 13, of the
California Administrative Code.


I.    INTRODUET ION
      General Motors Corporation (GMC), of Warren, Michigan, has requested for
an exemption from the prohibitions of California Vehicle Code Section 27156

for an engine modification program.     GM proposes to make available an engine

modification package, California Upgrade for Economy (CUE), for upgrading 1975

through 1981 model 8¥—92TA and 1976 through 1981 model 6V—92TA General Motors
Detroit Diesel Allison Division (GM—DDAD) heavy—duty engines.     The

modification of these older engines will utilize some components of 1982

California certified SV—92TA and 6V—92TA GM—DDAD engines to a hybrid

specification.    The purpose of the CUE modification, according to GMC, is to

improve performance and fuel economy.

II.    "CUE" PACKAGE DESCRIPTION
      GMC proposes, in their CUE program, to replace certain 1975 through 1981

OEM engine parts during a routine rebuild or a special rebuild solely for fuel

economy improvement with components utilized on 1982 model year California ‘

certified engines.    The parts which are to be upgraded are cyTinder Tiners,

gear train (for the blower drive gear), fuel injectors, blower, turbocharger,

aftercooler, air inlet housing, throttle delay check valve, camshaft, and

piston rings.    Tables I and II (attached) Tist these parts by GMC part

numbers.


III.    EVALUATION

       GMC did not submit any test data to show that the modification will have

possible effects on emissions.

       In response to GMC‘s request, the staff reviewed the parts list and

compared with GMC certification document to assure that the components used in

the CUE package are those parts used in 1982 California certified engines.
Because not all parts contained in the CUE package are listed in GMC‘s

certification application, only a partial list of the parts were cross—checked

and verified.    It may be assumed that the other parts not listed in the

certification application (cylinder Tiner, gear train for blower drive gear,

air inlet housing, throttle delay check vaive, camshaft, and piston rings),

when updated to the 1982 configuration which was designed to meet more

stringent emission standards, will not have, if any, adverse effect on
emissions.

IV.    DISCUSSION

       Per Air Resources Board (ARB) engine change policy (ARB Mail Out

No. 81—040) pertaining to heavy—duty vehicles, an engine which is rebuilt to

non—OEM configuration must be reviewed by the ARB and receive a written

exemption prior to rebuild.
       Since the components replaced are currently utilized on certified 1982

engines, the staff is of the opinion that there will be no adverse effect on

emissions during the rebuild of the subject engines.

V.     RECOMMENDAT ION

       The staff is of the opinion that the GMC engine modification package in

the CUE program during rebuild of 1975 through 1981 model 8¥—92TA and 1976

through 1981 model 6V~92ZTA engines will not have any adverse effect on

emissions.   The staff, therefore, recommends that Executive Order No. D—126 be

adopted.
