power strokes

Combustion's driving phases

Power strokes are the phases in an engine cycle when combustion forces the piston down, generating the mechanical energy that drives the crankshaft.

In a four-stroke engine, only one of every four strokes produces power.

The term extends to any forceful, productive phase of a repetitive motion—the pull phase in rowing, the downward push in cycling: She focused on maximizing her power strokes during the sprint.
