Abstract (en)
The invention provides an internal combustion engine (100) comprising a crankshaft (110) and at least one combustion chamber (120). The at least one combustion chamber (120) comprises at least one inlet port (121) for a fuel mixture, and at least one exhaust port (122) for exhaust gases. The at least one combustion chamber (120) comprises a first piston (130) coupled to the crankshaft (110) for reciprocating the first piston (130) in the at least one combustion chamber (120) for a first compression of the fuel mixture during a first duration up to a first compression ratio (CR1) below auto-ignition. The at least one combustion chamber (120) comprises a second piston (140) coupled to a drive system (150) for reciprocating the second piston (140) in the at least one combustion chamber (120) for a second compression of the fuel mixture, in addition to the first compression, during a predetermined second duration, shorter than the first duration, at least up to a second compression ratio for auto-ignition.
