The terminal cascade

In the terminal cascade the powerful transistor settles down, he switches on and off a current to the ignition coil (or to ignition coils). Thanks to it high currents cannot damage sensitive electronics of the block of management.

Terminal cascades of separate engines settle down:

  • In the engine capacity of 74 kw near to the ignition coil;
  • In the engine capacity of 92 kw over ignition coils on a head of the block of cylinders;
  • In the four-cylinder engine capacity of 110 kw under a cover of the case of the air filter;
  • In the six-cylinder engine also under a cover of the air filter.
