components           that        make     up      the    modifilcation             kit:         the    injection

timing        advance       unit,         the      nozzle           and   holder,             and    the     timing

pointer.           The     nozzle         has      four       holes with          different          angles.       The

Injection          timing        advances         from    9    degrees       to    13    degrees       or    from     7

modification             kit      (see    Appendix            1).     The    data       show    a    44%    decrease

NOx.        Although       the modification                   increased          NOx,    the    emission          leve!

stil!       meets    the    optional             NOx    standard          for     the        1987    model—year.

The    data also show a horsepower                            increase       from 180 to 190 and                   fusl

economy       improvement of              5 percent.

              The staff           based the evaluation of                        the modification kit                on

the    appliicant‘s         data.

  The model year 1988 OM 366LA engines use different timing and different injection nozzie
