6 and 8-cylinder petrol engines

The basic data

Engines DOHC 2.4, 3.0, 4.2 l - V-shaped, with a corner of an arrangement of cylinders 90 , accordingly on 3 and 4 cylinders abreast. Such engines are designated V6 and V8.

Engines have three inlet and two final valves on the cylinder. Each number of cylinders of the engine has on 2 camshafts. At engine V6 camshafts of final valves are set in motion by a gear belt, camshafts of inlet valves are set in motion by a chain from camshafts of final valves. At engine V8 four camshafts, also as well as auxiliary units, are set in motion by several chains. Privodnye chains are located from outside a flywheel (the check point party).
