                                    SUMMARY




       Righetti Enterprises,   of 1627 East Channel Street,   Stockton, California,

95205 has applied for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code (VC) for their RE—1 Aneroid System.      The RE—1

Aneroid System is designed for installation on all 1974 and older model—year

heavy—duty turbocharged Cummins diesel engines equipped with a PTG fuel pump.

       Righetti Enterprises has submitted a complete application and all the

required information including a video tape demonstrating the device and the

"snap—idle" test results.    Based on an engineering evaluation of the test data

and application materials,   it was determined that the RE—1 Aneroid System does

not have any significant adverse effects on emissions.

       The staff recommends that Righetti Enterprises be granted exemption as

requested and that Executive Order D—263 be issued for the RE—1 Aneroid System.

               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

        Righetti Enterprises,   of 1627 East Channel Street,   Stockton,   California,

©95205 has applied for an exemption from the prohibitions in Section 27156 of

the California Vehicle Code (VC) for their RE~1 Aneroid System.       The RE—1

Aneroid System is designed for installation on all 1974 and older model—year

heavy—duty turbocharged Cummins diesel engines equipped with a PTG fuel pump.

        Righetti Enterprises has submitted a complete application and all the

required information including a video tape demonstrating the device and the

 "snap—idle" test.




II.     CoNCLUSTONS

        Based on an engineering evaluation of the operating principles and

 "snap—idle" test data of the Righetti Enterprises RE—1 Aneroid System, the

staff concludes that the installation of the Righetti Enterprises RE—1 Aneroid

System will not adversely affect exhaust emissions from vehicles for which an

exemption is requested.




III.   RECOMMENDATION

       The staff recommends that Righetti Enterprises be granted exemption as

requested and that Executive Order D—263 be issued for the RE~1 Aneroid System.


IV.      DEVICE DESCRIPTION

          The RE—1 Aneroid System decreases fuel flow to the engine during low

intake manifold air pressure conditions such as rapid throttle opening.        The

device may be installed on any 1974 and older model—year Cummins turbocharged

engine equipped with PTG fuel pump not already equipped with an Air Fuel

Control (AFC) or aneroid system.       The RE—1 is similar to the Cummins optional

aneroid which is no longer available.       The RE—1 is a 6061 T6 billet aluminum

vaive body with two drilled passages (see drawings in Appendix B).

          Four hose connections are provided with the device.    The fuel bypass is

plumbed from the pressure side of the existing fuel pump to the inlet of the

aneroid fuel bypass passage.       The aneroid fuel bypass passage outlet is

connected to the existing pump suction fitting on the fuel pump.       The aneroid

leak—off line connects the plunger passage with the existing fuel tank return

lines.     The air signal line connects the aneroid cover with the intake

manifold.

         Upon initiation of rapid acceleration, the turbocharger cannot increase

the intake manifold pressure to supply sufficient air for the proper air/fuel

mixture.    The resulting rich mixture causes emission of thick smoke.

         During periods of low manifold pressures, such as during rapid

acceleration, the aneroid reduces the fuel charge to each cylinder by lowering

the fuel rail pressure.       As the turbocharger increases the intake manifold

pressure, the fuel pressure increases to rated pump calibration volume and

pressure.    According to the manufacturer, the system, if properly adjusted,

reduces the smoke opacity while not affecting performance.


       RE—1 ANEROID SYSTEM EVALUATION AND DISCUSSION

       A snap—idle test procedure was conducted to evaluate the emissions

impact of the RE—1 Aneroid System.      The emissions requlation for applicable

vehicles is not to emit smoke with an opacity greater than 55 percent.

        Snap—idle testing was performed in accordance with California Code of

Regulations (CCR) section 2182 et sq. by ARB North Heavy—Duty Diesel Section on

a 1972 model—year Cummins 855 CID heavy—duty diesel engine, model number NTC

350.   Two tests were run back—to—back; the first with the aneroid disabled, the

second with the aneroid enabled and adjusted to optimum level.

       Results are as follows:

                                 With Aneroid Disabled

                        Run Number          Percent Opacity

                             1                   100

                            2                    100

                             3                   100

                            4                    100

                            5                    100

                            6                    100

                                With Aneroid Enabled

                        Run Number         Percent Opacity

                            1                   40

                            2                   40

                            3                   43

                            4                   44

                            5                   45

                            6                   45

                            7                   53


The test results show the aneroid system‘s ability to control the smoke opacity

within the prescribed level.    With the aneroid disabled, the engine emitted

100 percent opacity smoke.     The aneroid was enabled and adjusted to reduce

smoke opacity without a significant loss of throttle response.     The test

results and the video tape of the test demonstrate the aneroid‘s ability to

meet emission standards and, therefore, the aneroid will not have a negative

impact on the vehicle‘s emissions.
