Different systems of ignition

  • In the engine capacity of 74 kw establishes system of ignition Motronic with the distributor. In this engine ignition installation since adaptation of the moment of ignition to each situation in engine work is is carried out becomes exclusively electronic way.
  • In the engine capacity of 92 kw establishes system of ignition Motronic without the distributor. In this system of ignition on two cylinders it is necessary on one coil of ignition. It gives a spark while it is necessary for one of two cylinders. It does excessive the ignition distributor. A by-effect of such division: each cylinder receives for one running cycle on a step of an exhaust one more (unnecessary, but harmless) a spark.
  • The four-cylinder engine capacity of 110 kw also is equipped by system of ignition Motronic without the distributor. Difference from the engine capacity of 92 kw: here each cylinder has a coil of ignition with own management. The unnecessary spark is not present, and each cylinder can separately cope.
  • The system of ignition MPI and MPFI the six-cylinder engine is a component of management of engine work. Here, as well as in the engine capacity of 92 kw, on each two cylinders it is necessary on one coil of ignition.
