| 摘要 |
The present invention relates to a six stroke internal combustion engine (10) comprising a combustion chamber (20) and a piston (14). The engine (10) is adapted to perform the following subsequent strokes:
- an intake stroke, introducing a first fluid into said combustion chamber (20);
- a compression stroke, compressing said first fluid;
- a power stroke, igniting said first fluid to thereby cause a combustion producing combustion products;
- a first exhaust stroke, evacuating at least a portion of said combustion products, said first exhaust stroke being performed such that a predetermined combustion product portion of said combustion products intended to be evacuated by a piston movement is retained in said combustion chamber (20) after said first exhaust stroke has been completed;
- a fluid expansion stroke, introducing and expanding a second fluid in said combustion chamber (20) resulting in second fluid products, and
- a second exhaust stroke, evacuating said second fluid products.
