                                               SUMMARY




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

           Order D—161—18, which exempts their Turbocharger System Model 6.2G from the

           prohibitions in Vehicle Code Section 27156, to include the 1992 model year

           Chevrolet/GMC vehicles powered by a 6.2L heavy—duty diesel engine.

                The 1992 model year 6.2L Chevrolet/GMC heavy—duty diesel engine is

           carried over from the previous year for which an exemption has been granted.

           In addition,   smoke opacity tests conducted at Gale Banks shows that the add—,

           on turbocharger system will have no adverse effect on exhaust emissions from

           the engine for which the exemption update is requested.

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

           that Executive Order D—161—26 be issued.

EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARQER SYSTEM MODEL 6.2G
     FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156
              IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE
                       CALIFORNIA CODE OF REGULATIONS
I.   INTRODUCTION

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

91702, has requested an update to Executi&e Order (E.0.) Db—161—18 to include

the 1992 model year Chevrolet/GMC vehicles powered by a 6.2L heavy—duty

diesel engine.      The E.0. D—161—18 currently exempts Bank‘s Turbocharger

System Model 6.2G from the prohibitions of Vehicle Code (VC) Section 27156

for 1982—1991 model year Chevrolet/GMC vehicles pqwered by a 6.2L heavy—duty

diesel engine.

II.    CONCLUSION

      Since the 1992 model year 6.2L Chevrolet/GMC heavy—duty diesel engine

is carried over from the previous year for which an exemption has been

granted and the snap—idle test results indicate that smoke opacity of the

modified vehicle was less than the 40 percent standard,     the staff believes

that the add—on turbocharger system will have no adverse effect on exhaust

emissions from the engine for which the exemption update is requested.

III. RECOMMENDATIONS

      The staff recommends that Banks be granted an exemption for the add—on

turbocharger system model 6.2G for 1982—1992 model year Chevrolet/GMC

vehicles powered by a 6.2L heavy—duty diesel engine and that Executive Order

D—~161—26 be issued.

IV.    TURBOCHARGER KIT DESCRIPTION AND OPERATION

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

output of the engine by compressing the intake charge to pressures above

that of the atmosphere.      This increased pressure allows a greater charge

density to enter the combustion chamber and increase the volumetric

efficiency of the engine.      The maximum fuel delivery is slightly increased

to maintain proper air—fuel ratios when the turbocharger is providing

                                         —1—


positive manifold pressure (boost).       Maximum positive manifold pressure is

limited to 10 psi by the size of the turbine and the compressor.       The

maximum engine speed is reqgulated by the original equipment manufacturer

(OEM) fuel injection governor.    Controlling the maximum engine speed also

controls the maximum engine turbine speed and corresponding boost pressure.

     The major components of the kit include a 1.0 air ratio (A/R)

Rotomaster Model No. TO4B turbocharger, custom intake and exhaust tubing,

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

the installation.   Modification to the OEM emission related parts due to the

installation of the turbocharger system include replacement of the air

cleaner assembly and replacement of the OEM exhaust system with a 3"

diameter exhaust system.    To meet the newly implemented opacity standard of

40 percent, Banks has modified the compressor wheel from a U trim compressor

wheel to an H3 trim compressor wheel.

v.   DISCUSSION

     The applicant is making the add—on Turbocharger System Model 6.2G

available for 1992 model year Chevrolet/GMC vehicles powered by a 6.2L

heavy—duty diesel engine.    Certification documents show that the 1992 model

year 6.2L Chevrolet/GMC heavy—duty diesel engine is carried over from the

previous year for which the turbocharger system has been exempted.

Previous testing of the turbocharger showed no adverse affect on exhaust

emissions.   However,   starting with the 1992 model year heavy—duty diesel

vehicles, snap—idle smoke opacity testing was required pursuant to

California Code of Regulations (CCR) Section 2182, Heavy—Duty Diesel Vehicle

Smoke Opacity Test Procedures.     The overall smoke opacity could not exceed

40 percent as required by the CCR Section 2182      (c).   In the past, Gale Banks

through the Specialty Equipment Manufacturers Association (SEMA), claimed

that the current aftermarket turbocharged confiquration could not meet the

40 percent opacity standard because turbochargers do not kick—in immediately

                                      :   —2—


         upon engine start up.   Thus, during transient periods, air is momentarily

         restricted even though fuel is increased,   causing an increase in peak smoke.

         To meet the 40 percent opacity standard, Banks modified the turbocharger

         system to use a new Schwitzer or Garrett H3 trim compressor wheel    (part

         numbers 166198 and 408105—5371 respectively)}).   The H3 trim compressor wheel

         reduces the response time (boost to fuel) of the turbocharger which has a

         favorable impact on particulate emissions as well as meeting the 40 percent

         opacity standard.   The new trim compressor wheel does not change the overall

         characteristics of the turbocharger.    The applicant claims no other

         modifications to the system are necessary for installation on 1992 model

         year applicable vehicles.

              Smoke opacity testing was conducted at the Gale Banks Engineering

         facility using a 1989 GMC truck powered by a 6.2L heavy—duty diesel engine

         to determine if the vehicle with the turbocharger installed is within the 40
222. ‘




         percent standard.   Bank‘s opacity readings are shown below.




                              Snap—Idle Smoke Opacity Test Results




                                          30%, 29%, 30%




         The snap—idle test results indicate that smoke opacity of the modified

         vehicle was less than 40 percent.    This demonstrates that the addition of

         the Gale Banks Turbocharger System Model 6.2G will not have an adverse

         effect on emissions for 1982—1992 Chevrolet/GMC 6.2L heavy—duty diesel

         engine for which the exemption was requested.

              Banks has sfibmitted all the required information and fulfilled the

         requirements for an exemption.
