Two Stroke Engine

A once-common type of engine now found almost exclusively in off-road motorcycles. A two-stroke motor fires once with every two strokes of the piston.

  1. Once fired, the downward stroke of the piston delivers power and then draws in a mixture of fuel, air and oil which displaces the exhaust gases in the combustion chamber

  2. The upward stroke compresses the mixture for ignition
