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

Engines can be classified based on the valve arrangement as follows:

1. Overhead Valve (OHV) Engine: The valves are located above the piston and are operated by push rods.
2. Overhead Cam (OHC) Engine: The camshaft is located above the cylinder head, which controls the valves directly.
3. Single Overhead Cam (SOHC) Engine: A single camshaft controls both the intake and exhaust valves.
4. Double Overhead Cam (DOHC) Engine: Two camshafts are used, one for intake valves and one for exhaust valves.
5. Side Valve Engine: The valves are located beside the piston, typically used in older engines.
