| 摘要 |
The i.c. engine combustion chamber, formed between an outer shell (1, 2) and two adjacent pistons (3, 6) which are set at a variable angle to one another, comprises an open cavity (13) adjacent to the outer edge (14) of one piston, whose volume is basically that of the combustion chamber at the end of its compression phase. The cavity is made in the front face of one piston (3) in the direction of its rotation, while the facing piston (6) has a peak (18) which partially closes the combustion chamber at the end of the compression phase. The peak has a notch which maintains communication between the cavity and an injector or igniter (16) in the wall of the outer shell. The cavity is also linked to the main chamber (12) by a channel (17). ADVANTAGE - Improved filling with fuel and subsequent combustion.
