摘要： PROBLEM TO BE SOLVED: To impart the fuel consumption improving effect by lean combustion; and to expand a traveling area for obtaining the effect. SOLUTION: Burnt gas is exhausted from exhaust stroke side preceding cylinders 2A and 2D between a pair of cylinders overlapping in an exhaust stroke and an intake stroke, and is introduced as it is into intake stroke side succeeding cylinders 2B and 2C via a gas passage 22 between the cylinders, and only gas exhausted from the succeeding cylinders 2B and 2C is introduced into an exhaust passage 20. Combustion is performed in the lean air fuel ratio larger by a prescribed quantity than the theoretical air fuel ratio in the preceding cylinders 2A and 2D, and the combustion is performed by supplying fuel to the burnt gas introduced from the preceding cylinders 2A and 2D in the succeeding cylinder 2B and 2C. Fuel supply to a prescribed cylinder is stopped in the prescribed timing when an air-fuel mixture temperature of the succeeding cylinders 2B and 2C is a relatively high state. COPYRIGHT: (C)2004,JPO

摘要： PURPOSE:To improve the output and the fuel cost of an engine by obtaining a six-stroke engine adapted for successive operation of strokes of suction, compression, and combustion of air-fuel mixture, exhaustion of the burned gas, air suction, and air exhaustion. CONSTITUTION:A cylinder head of a reciprocation engine is provided with an air suction valve 8 near the central part as well as with a conventional suction valve 2 and exhaust valve 6. After strokes of suction, exhaustion, and combustion of air- fuel mixture and exhaustion of the burned gas, particularly, when a piston 1 reaches the top dead center and the exhaustion of the burned gas is finished, the exhaust valve 6 is closed and the air suction valve 8 is opened for sucking in air. In this construction, burned gas remained in a cylinder is diluted by the air. Then, when the piston 1 is risen from the bottom dead center, the air suction valve 8 is closed, and again the exhaust valve 6 is opened to exhaust the air. Subsequently, similar strokes are repeatedly operated for obtaining power.

摘要： PROBLEM TO BE SOLVED: To provide a spark ignition internal combustion engine capable of performing good combustion in both self ignition combustion and spark ignition combustion, also easily ensuring durability of the engine and a seal property of combustion gas. SOLUTION: An internal combustion engine is provided with a first/second intake valves 30 and a first/second exhaust valves 34, respectively opening/ closing a first/second intake passages 22 and a first/second exhaust passages 26 opened to a combustion chamber 18 synchronously with rotation of the engine, and a control valve 46 changing actual compression ratio of the engine by changing open/close timing of both the intake valves 30. In this constitution, the actual compression ratio at self ignition combustion time and the actual compression ratio at spark ignition operation time are made different by this control valve 46.
