Engine design features
The body is machined from castings. The cylinder block of the power unit is cast from gray cast iron. The cylinder liners are pressed into a rigid power belt of the water jacket finning. The cylinder head block is bolted with permanent tightening torque. The cooling system is liquid, it combines the flow cavities of the head and the cylinder block.
One-piece forged steel crankshaft. The seats of the connecting rod and main journals are hardened by HFC hardening. The main bearings are lubricated through the holes in the crankshaft journals.
A cast iron flywheel is attached to the rear end of the crankshaft and is equipped with a gear ring for starting the engine with a starter. The torsional vibration damper is a liquid damper designed to damp excess vibration. Vibration and noise levels have been brought up to European standards.
