Question

which engine stroke pushes the piston from tdc to bdc?
select one:
a. intake
b. compression
c. power
d. exhaust

Explanation:

In an engine's four - stroke cycle:

• The intake stroke draws in the air - fuel mixture with the piston moving from TDC (Top Dead Center) to BDC (Bottom Dead Center).
• The compression stroke compresses the mixture with the piston moving from BDC to TDC.
• The power stroke ignites the mixture and pushes the piston from TDC to BDC to produce power.
• The exhaust stroke expels the exhaust gases with the piston moving from BDC to TDC.

Answer:

C. Power
