Compared to spark-ignition engines, when is fuel introduced in a Diesel engine?
Answer
Injected near the end of the compression stroke
In Diesel's design, fuel is sprayed into the superheated air near the peak of the compression stroke, whereas in spark-ignition engines, the fuel and air are typically mixed beforehand.
