  • Application


Engine type. 8-cylinder diesel engines; with V-type cylinder arrangement, 4-stroke, with direct fuel injection, turbocharged, water-cooled, with supercharged air intercooler installed on the vehicles.

Ecology. Engine meets the emission class for road machinery – UN Regulations No. 49-05C (level В1with EOBD), No.24-03 - euro-4.

Design features

The following design solutions were used to meet the parameters of the emission class euro-4 - UN Regulations № 49-05C (B1)

  • application of SCR system,
  • common rail,
  • boosting system modernization.

Installation by a customer of a selective catalytic reduction system (SCR) into EGR system including metering module together with diesel exhaust fluid tank and selective catalyst (damper-catalyst).

Fuel supply system

Fuel supply system: of common rail type with electronic fuel supply control. The system provides injection pressure up to 1800 bar.

The fuel supply system includes:

  • HP fuel pump 47.5 ("YZDA", Yaroslavl),
  • fuel rails (HP accumulators) with built-in fuel pressure sensor – (Germany),
  • electro-driven injectors with built-in solenoid valve ("AZPI", Barnaul),
  • electronic control unit – microprocessor ECU М240 ("ABIT", St. Petersburg),
  • sensors:
    • - timing sensor,
      - supercharged air pressure and temperature sensors,
      - oil pressure sensor,
      - coolant temperature sensor,
      - fuel temperature and pressure sensors.


The engines may be completed with clutches and gearboxes of different manufacturers, including: YMZ, Sachs, Hammer, etc.

There is a possibility to install

  • pneumatic system compressor drive,
  • steering booster pump,
  • air conditioner compressor drive.
