Question

Name various types of engine, on the basis of valve arrangement.

Hint:

The valve arrangement affects the engine’s performance, efficiency, and complexity, with OHV being simpler and DOHC offering better performance.

Answer 1

Engine valve configurations are categorized as follows:

1. Overhead Valve (OHV) Engine: Valves positioned above the piston, actuated by push rods.
2. Overhead Cam (OHC) Engine: Camshaft situated above the cylinder head, directly actuating the valves.
3. Single Overhead Cam (SOHC) Engine: A solitary camshaft manages both intake and exhaust valves.
4. Double Overhead Cam (DOHC) Engine: Employs two camshafts; one for intake and another for exhaust valves.
5. Side Valve Engine: Valves are located adjacent to the piston, commonly found in older engine designs.
