70% to passWhen is fuel injected into a cylinder of diesel engines?
AAfter combustion gases in the cylinder have expanded.
BAs air is taken into the cylinder.
CAfter air in the cylinder is compressed.
DBefore air in the cylinder is compressed.
AI Explanation
The correct answer is C) After air in the cylinder is compressed. In a diesel engine, fuel is injected into the cylinder after the air has been compressed. This allows the fuel to ignite and combust, generating the power that drives the engine. The compression of the air inside the cylinder increases its temperature, which in turn causes the injected fuel to ignite and burn. The other answer choices are incorrect because they do not accurately describe the timing of fuel injection in a diesel engine.
