which stroke in the four-stroke cycle begins as the piston reaches bdc after combustion takes place? ?
Homework Answers
Suction stroke - the piston moves from TDC to BDC for the first time
Compression stroke - the piston moves from BDC to TDC.
Power stroke - the piston moves from TDC to BDC for second time in a cycle(combustion has taken place by the end of this stroke)
And the answer to the question
When the piston reaches BDC after combustion the next stroke is
"EXHAUST STROKE" :The scavenging of by products takes place in this stroke.
Add Answer to:
which stroke in the four-stroke cycle begins as the piston
reaches bdc after combustion takes place?...
