    摘要： Plural cylinders are divided into cylinder groups consisting of the cylinders each having an equal inspiration stroke. The cylinder groups are so disposed as to allow their inspiration strokes to be apart from each other in a direction parallel to a crank axis in which a crankshaft extends. On its side surface, the cylinder head has an opening for an intake port which is communicated with an individual intake passage. Each of plural individual intake passage is extended from the respective cylinders for each cylinder group in the direction extending or elongated over the cylinder head and merged together at that location into a merged intake passage. The merged intake passage is extended toward the intermediate position between the two cylinder groups and thereafter curved, followed by extending toward the side of one side surface of the cylinder head.

    摘要： An improved intake system in an internal combustion engine of a high compression ratio capable of producing a swirl of air-fuel mixture so as to increase the combustion speed thereof for improved combustion efficiency and hence fuel economy during light-load operation of the engine, and at the same time of effectively suppressing the generation of a swirl so as to reduce the level of combustion noises to a substantial extent during heavy-load operation of the engine at full-open throttle. The engine has a combustion chamber defined in a recess in the cylinder head above the top of a piston, slidably received in a cylinder bore in the cylinder block, at its top dead-center, with a squish area of a limited clearance formed adjacent the combustion chamber in the cylinder bore between the cylinder head and the piston. An intake passage in the cylinder head leading to the combustion chamber for supply of air-fuel mixture comprises a light-load intake passage for admitting the mixture into the combustion chamber or the squish area in the circumferential direction of the cylinder bore so as to produce a swirl under light-load operation of the engine, and a heavy-load intake passage having a valve adapted to be closed during light-load operation of the engine and opened during heavy-load operation of the engine for admitting the mixture into the combustion chamber or the squish area in the direction parallel to the central axis of the cylinder bore so as to suppress the generation of a swirl.

    摘要： Disclosed is a supercharged direct-injection engine, which comprises a supercharging device (25, 30) for compressing intake air, and an injector 10 for directly injecting fuel into a combustion chamber 5. In the engine, an excess air factor λ as a ratio of an actual air-fuel ratio to a stoichiometric air-fuel ratio, at least in an engine warmed-up mode, is set to 2 or more in the entire engine-load region. Further, compressed self-ignited combustion is performed in a low engine-load region, and a supercharging amount by the supercharging device (25, 30) is increased along with an increase in engine load in a high engine-load region to allow the excess air factor λ to be kept at 2 or more. The engine of the present invention can effectively reduce NOx emission, while improving fuel economy.
