GENERAL INFORMATION

The block of cylinders and the details located in the block of cylinders of the DOHC engine, generally are similar to the ONS engine of 2,0 l. Difference is that pistons are attached to rods by piston fingers of floating type and are fixed by lock rings.

Camshafts on DOHC engines are given from a cranked shaft by one gear belt. In each cylinder it is established on four valves (two inlet and two final) which are put in action from camshafts through hydraulic pushers. One camshaft puts in action inlet the valve, and another – final.

Models with DOHC engines have a separate oil radiator.

The distributor of ignition is put in action from a camshaft operating final valves.

The gear belt also puts in action the water pump, but for adjustment of a tension of a gear belt the additional roller is used. Also there is one more directing roller of a gear belt.
