  • 2-Stroke Engines
    The operation of a 2-stroke engine involves two-piston movements (strokes) and one crankshaft revolution, hence the name; 2-stroke. Combustion occurs in the same way as any internal combustion engine (such as a car engine) with the "suck, squeeze, bang, blow" principle which is explained a little further below but the mechanical components of a 2-stroke engine are slightly different as:
    The piston also controls the opening and closing of the inlet and exhaust ports instead of valves and
    The crankcase (bottom of the engine where the rotation of the engine occurs) is used during the induction process
    There is no oil reservoir, hence the need to add 2-stroke lubricating oil to the fuel
