                                              SUMMARY




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

            Order D—161—17, which exempts their Turbocharger System Model 6.9F from the

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

            Ford Motor Company vehicles powered by a 7.3L Navistar International heavy—

            duty diesel engine.

                 The 1992 model year 7.3L Navistar International 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
mm




            that Executive Order D—1651—25 be issued.

         EVALUATION OF GALE BANKS ENGINEERING‘S ADD—ON TURBOCHARGER SYSTEM MODEL 6.9F
              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 Executive Order (E.0O.) D—161—17 to include

         the 1992 model year Ford Motor Company vehicles powered by a 7.3L Navistar

         International heavy—duty diesel engine.     The E.0. D—l61—17 currently exempts

         Bank‘s Turbocharger System Model 6.9F from the prohibitions of Vehicle Code

         (VC) Section 27156 for 1988—1991 model year Ford Motor Company vehicles

         powered by a 7.3L Navistar International heavy—duty diesel engine.

         II.    CONCLUSION

               Since the 1992 model year 7.3L Navistar International heavy—duty diesel

         engine is carried over from the previous year for which an exemption has
(f9m.,




         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 6.9F for 1988—1992 model year Ford Motor Company

         vehicles powered by a 7.3L Navistar International heavy—duty diesel engine

         and that Executive Order D—161—25 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

                                              —~1—


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

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

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

limited to 7 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 or a Schwitzer/Banks Model No. TO4B2S

turbocharger, custom intake and exhaust tubing, air cleaner assembly,

brackets, hoses and the hardware nécessary 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.     Also, the fuel setting is reduced five (5) percent for

1992 models by turning the fuel pump adjustment screw 60 degrees (1/6 turn

clockwise},   instead of the 90 degrees (1/4 turn clockwise) adjustment for

the previous models.

v.   BISCUSSION

     The applicant is making the add—on Turbocharger System Model 6.9F

available for 1992 model year Ford Motor Company vehicles powered by a 7.3L

Navistar International heavy—duty diesel engine.     Certification documents

show that the 1992 model year 7.3L Navistar International 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

                                       —2«—


     year heavy—duty diesel vehicles, snap—idle smoke opacity testing was

     required pursuant to California Code of Reqgulations (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

     configuration could not meet the 40 percent opacity standard because

     turbochargers do not kick—in immediately 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
m




     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.     Furthermore, the fuel setting for 1992

     model year California certified engines is reduced five (5) percent due to

     the snap idle test requirements.    Since the H3 trim wheel does not change

     the overall characteristics of the turbocharger and the fuel adjustment (90

     degrees or 1/4 turn clockwise) of previous model years represent the ‘worst

     case‘ condition, no additional emission testing (other than the smoke

     opacity test) was required.    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 1991 Ford Super—Duty truck powered by a 7.3L Navistar
on




     International heavy—duty diesel engine to determine if the vehicle with the

                                            —3—


turbocharger installed is within the 40 percent standard.   Bank‘s opacity

readings are shown below.




                    Snap—Idle Smoke Opacity Test Results




                                 22%, 23%, 22%




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 6.9F will not have an adverse

effect on emissions for 1988—1992 Ford Motor Company vehicles powered by a

7.3L Navistar International heavy-duty diesel engine for which the exemption

was requested.

     Banks has submitted all the required information and fulfilled the

requirements for an exemption.
