Combustion Chamber Shapes

Combustion Chamber Shapes Points : combustion chamber shapes, the combustion chamber and combustion, problems in internal combustion engines, ic, engine, auto diesel The shape of the combustion chamber has an important bearing upon the output and thermal efficiency of the engine. The shape depends upon the disposition of the valves. If the valves are in the cylinder head, it is possible to approximate to the spherical shape. The inclined overhead valves and dished piston are the nearest practical approach to spherical shape.

Mot overhead valve engines give more turbulence to the fresh charge and also give less heating to the incoming charge. Another arrangement, in which, the inlet valve is over the exhaust. This arrangement enables a single camshaft to be sued; the inflowing mixture also cools the exhaust valve.
