ABSTRACT:
The present invention relates to a controlled-ignition direct fuel injection, four-cycle internal combustion engine including a combustion chamber (3) in which at least two intake lines (31, 32) terminate through ports (21, 22, 23) and an exhaust line (5), each of which can be closed by a means such as a valve (41, 42, 6), at least one ignition means (7; 11), a means (9) for direct injection of fuel into said combustion chamber (3). According to the invention, the intake ports (21, 22) are diametrically opposite each other. In addition, at least one of ignition means (11) has an axis disposed perpendicularly to the outer surface of the fuel jet generated by injection means (9 ).
