Description

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 product.

Ecology. Engine meets the emission class for off-road machinery – UN Regulations No. 96-02, No. 24-03.

Design features. The following design solutions were used to meet the parameters of the UN Regulations No. 96-02, No. 24-03 – application of common rail with increased fuel injection energy.

Options

There is a possibility to install

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


Fuel supply system

Fuel supply system: of common rail type with electronic fuel supply control. The system provides injection pressure up to 1600 bar.

The fuel supply system includes:

  • HP fuel pump 47.5, fuel boost pump (“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.
