  1. As of 09/92 modified fuel injection valves have been used. The fuel outlet (a) has been converted from 4 to 2 holes which results in improved fuel formation.
  2. Due to the arrangement of the holes (a) the fuel forms 2 streams when it flows out which spray the fuel onto both inlet valves as a finely atomized spray.
