Another name of diesel engine is

Answer: Option B

A diesel engine operates on the principle of compression ignition, where fuel is injected into highly compressed air inside the cylinder.

In a diesel engine, combustion occurs gradually during the early part of the expansion stroke, and the volume change during combustion is relatively small.

Because of this characteristic, a diesel engine is also referred to as a low volume combustion engine.

A constant volume combustion engine is associated with petrol engines operating on the Otto cycle, not diesel engines.

Hence, the correct answer is Option B – Low volume combustion engine.
