INTERNAL COMBUSTION ENGINES

摘要

A method of operating an internal combustion engine (2) including the steps of: introducing a first charge of air or air fuel mixture into a main cylinder (6) in which a main piston (8) is mounted for reciprocating movement; introducing a second charge of air fuel mixture into an auxiliary cylinder (24) in which an auxiliary piston (26) is mounted for reciprocating movement; causing the auxiliary piston to compress the second charge; igniting the compressed second charge; and transferring burning fuel and/or combustion products produced from the second charge to the main cylinder whereby any fuel in the first charge is burnt.
