<p>The invention relates to a piston (20) for a cylinder (16) of a two-stroke internal combustion engine (10), the engine having an auxiliary air inlet port (26) which communicates with a cavity (40) within the crown structure of the piston (20) as the piston passes through bottom dead centre. The cavity and contained air promotes and aids the combustion process to enhance low speed power, torque and evenness of engine running by reducing or eliminating engine pre-combustion "knock".</p> |
