A feature of the ZMZ-40524 engine control system is:

  • - the use of a throttle module with an electric motor that allows you to adjust the throttle position electronically to obtain the optimal mixture and the required torque flow characteristics on the car;
  • —the use of a drainless fuel line assembly with injectors with a working pressure in the line (400 ± 8 kPa), to reduce the evaporation of gasoline vapors.
  • - use of individual ignition coils to reduce the level of interference;
