YMZ-65861

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.

Options

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.
