Question

how many valve in diesel engine​

Answer 1

Answer:

A multi-valve engine design typically has three, four, or five valves per cylinder to achieve improved performance. Any four-stroke internal combustion engine needs at least two valves per cylinder: one for intake of air and fuel, and another for exhaust of combustion gases.

Answer 2

A number of valves in a diesel engine:

• The diesel engine usually has four valves.

• Commonly, every single cylinder can use either 2 (one intake and one exhaust) or 4 valves (two intakes and two exhaust).  

• In contemporary diesel engines, four-valve designs direct and offer some key advantages over two-valve designs i.e. it enhanced mixture formation resulting from the central, vertical injector.
