5th generation engines fulfil the emission requirements set by the authorities (AWF/ATF: EU97/68/EC Stage IV and EPA 40 CFR 1039 Tier 4 Final). The manufacturer guarantees that all engines of this type are equivalent to the engine that is officially approved.

The AGCO POWER 168 AWF engine is water-cooled, turbocharged four-stroke diesel engine. The 60° Vangle
engine is equipped with wet cylinder liners, which are supported at the middle. The engine has
double Interstage charge air cooling (ICAC), double 2-stage turbocharging and double Exhaust gas
recirculation (EGR) system.

The cylinder block is the main body of the engine, to which other engine parts are attached. Wet and replaceable cylinder liners are supported at the middle, which reduces vibrations and directs coolant circulation mainly to the upper part of the liners.

The seal between the lower part of the cylinder liner and the cylinder block is achieved by three Orings.
The O-rings are fitted in grooves in the cylinder block.The upper part is sealed by the cylinder head gasket.
The camshafts are located in the cylinder block.

There are separate bearing sleeves in all camshaft bearing locations and the drilling for the camshaft rear end is covered with a plug.
