Azusa, California 91702, using a Rotomaster turbocharger Model No. TO4B or a
Schwitzer/Banks turbocharger Model No. TO4B25 with an A/R ratio of 1.0 has
been found not to reduce the effectiveness of required motor vehicle pollution
control devices and, therefore, is exempt from the prohibitions of Section
27156 of the Yehicle Code for 1982 through 1987 model—year Chevrolet/GMC
heavy—duty vehicles powered by a 6.2 liter General Motors heavy—outy diesel
engine.                                                  .

           Gale Banks Engineering (Banks) has requested an update to Executive

    Order D~161~3, which exempts their turbocharger kit mode! No. 6.2G for 1982—

    1987 model—year‘Chevrolet/GMC heavy—duty vehicles powered by a 6.2       liter

    General Motors heavy—duty diesel engine.~       They have requested that a

    turbocharger unit manufactured by an additional source (Schwitzer/

    Banks) be also exempted.

           Based ofi the following:       (1) comparative compressor performance maps

    submitted by Banks   indicating that the two turbochargers have simllar

    operating characteristics;    (2)   the fact that both turbochargers have an A/R

    ratio of 1.0; and (3)    test data from previous comparative exhaust emission

    tests performed for exempting the kit, the staff concludes that the Banks

‘   turbocharger k{t mcdél   No. 6.2G using the Schwitzer/Banks turbocharger wili

    not adversely affect exhaust emissions from 1982—1987 model—year

TITLE 13, OF THE CALIFORNIA ADMINISTRATIVE CODE



1.     JNTRODUCTION

       Gale Banks Engineering (Banks) of 546 Duggan Avenue, Azusa,

California 91702,         has requested an update to the existing Air Resources

Board Executive Order         (E.0.) D—161—3 dated October 23, 1986.   E.0. D—161—3

exempted the Bank‘s turbocharger kit mode! No. 6.2G from the prohibitions             in

Vehicle Code Section 27156 for 1982—1987 model—year Chevrolet/GMC heavy—duty

vehicies powered by a 6.2 liter General Motors heavy—duty diesel enéine,

The applicant has requested that a turbocharger unit         (the major component of

the kit) manufactured by an additional        source (Schwitzer/Banks) be also

exempted.      This would give Banks the freedom to procure turbocharger units

from two sources when assembling the kits for saile.

[E.         NCLUS   ION

       Based on the following:          (1) comparative compressor performance maps

submitted by Banks         Indicating that the two turbochargers have similar

operating characteristics; (2) the fact that both turbochargers have an A/R

ratio of 1.0; and (3)        test data from previous comparative exhaust emission

tests perférmed for exempting the kit, the staff conciudes that the Banks

turbocharger kit mode! No. 6.2G using the Schwitzer/Banks turbocharger wil|

not adversely affect exhaust emissions from 1982—1987 model—year

Chevrolet/GMC heavy—duty vehicles powered by a 6.2 liter General Motors

heavy—duty diesel engine.


LEH.     RECOMMENDAT IONS                                                                    =

          The staff recommends that Banks be granted an update as requested,

and that Executive Order D—161—7 be issued.

lV.<        RBOCHARGER KIT DESCRIPTION AND           OPERATION

          The purpose of the Banks turbocharger klt              is to increase the power

outpuf of the engine by           Iincreasing   Its volumetric eff?ciency.    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

fue!    delivery    is siightly     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 1.0 A/R ratio Rotomaster

model   No. TO4B or a Schwitzer/Banks Model No. TO4B2§5 turbocharger, custom

Intake gnd exhaust tubing, air cleaner assembly, brackets, hoses and the

hardware necessary to complete the installation.

         Maximum positive manifold pressure is limited to 10 psi by the size

of the turbing and the compressor.              The maximum engine speed     is regulated 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 corresponding boost pressures are also contrdlled.

         No OEM emission controls are removed or disconnected when the

turbocharger kit         is   installed.

v.       D1SCUsSS ION

         Banks has submitted compressor performance maps of both Rotomaster

Mode! No. TO4B and Schwitzer/Banks mode! No. TO4B2S turbochargers.                    Both


turbochargers are designed to have an A/R ratio of 1.0 (critical parameter).

The compressor maps indicate that the two turbochargers have similar

operating characteristics.   A copy of the compressor maps   is appended.
