摘要： A spark ignition internal combustion engine is described having a variable volume combustion chamber (10) defined by a cylinder head (12), a cylinder bore (14) and a piston (16) reciprocating within the cylinder bore (14). The cylinder head (12) has a spark plug (40) and intake and exhaust ports (20, 30) leading through intake and exhaust valves (26, 36) into the combustion chamber (10). A fuel injector (50) is provided for injecting liquid fuel directly into the combustion chamber (10) to produce a powerful ignition kernel for igniting a homogeneous premixed charge in the combustion chamber (10). The fuel injector (50) is positioned in an unswept part of the cylinder bore (14) and oriented to spray fuel obliquely towards the front face of the intake valve (26) in the direction of the spark plug (40). An engine management system (60) generates a spark at the spark plug electrodes at a predetermined spark timing in the engine cycle, and operates the injector (50) in a predetermined prior phase relationship with the spark timing to direct towards the vicinity of the spark plug gap (42) a small quantity of fuel only sufficient to generate at the time of ingition a localised region of readily ignitable mixture having its centre in the immediate vicinity of the spark gap (42). The resulting ignition of the localised ignitable region by the spark and the combustion thereof produces a powerful ignition kernel for igniting the premixed charge in the combustion chamber (10).

摘要： A cylinder injection type internal combustion engine wherein a recessed portion (22A) is formed in an upper surface of a piston (22) so as to produce and develop a vertical vortex current in which intake gas that is introduced into a combustion chamber (27) of the engine is directed from a lower side (21A) of a cylinder head (21) of the engine to the upper surface of the piston (22) and then from the upper surface of the piston (22) to the lower side (21A) of the cylinder head, and wherein a corner on an outlet side of the recessed portion (22A) where the vertical vortex current exits, is formed more bluntly than a corner of the recessed portion (22A) where the vertical eddy current enters, whereby fuel is directly injected into the combustion chamber (27). This cylinder injection type internal combustion engine can, in particular, stably burn thin fuel-air mixture in a stratified fashion on thereby reduce fuel consumption and, even in burning fuel-air mixture richer than the thin fuel-air mixture, it can ensure a high output, whereby it is possible to provide an internal combustion engine with high efficiency.
