Choose an option
-
ATrue
-
BFalse
Answer
Correct Answer: True
Explanation
Given data
- Engine type: compression-ignition diesel.
Concept/ApproachIn CI engines, air is compressed to a high pressure and temperature. Near the end of compression, finely atomized fuel is injected; the high air temperature causes auto-ignition without a spark.
