摘要： The invention relates to a reciprocating piston internal combustion engine, the compression ratio of a cylinder (1) being adjustable by means of a variable distance between the piston (4) and the cylinder head (3) in the top dead centre, preferably by altering the effective length of a connecting rod (4.1). The shape of the piston base is trough-like which is surrounded by a piston edge, the shape of which is designed, preferably, such that in the event of respectively different distances between the piston to the cylinder head (3) in the top dead centre, in particular if the adjusted effective rod length is different, an injection jet aligned in the direction towards the piston edge is deflected in the direction of the trough-like shaped base.

摘要： Diesel-cycle engines are known to have greater power, torque and efficiency compared to Otto-cycle engines of like displacement. When the fuel is a gaseous fuel, such as natural gas, a pilot fuel (such as diesel) is normally required to assist with ignition in a gaseous fuelled Diesel-cycle engine. It would be advantageous to reduce the power, torque and efficiency gap between a Diesel-cycle engine and a gaseous fuelled Otto-cycle engine. A combustion apparatus for a gaseous fuelled internal combustion engine comprises a combustion chamber defined by a cylinder bore, a cylinder head and a piston reciprocating within the cylinder bore. A diameter of the cylinder bore is at least 90 mm and a ratio between the diameter and a stroke length of the piston is at most 0.95. There is at least one intake passage for delivering a charge to the combustion chamber, and at least one intake valve is configured in the cylinder head and cooperates with the intake passage to create a predominant tumble flow motion in the combustion chamber.

摘要： In an internal combustion engine, an ignition plug is arranged near a center of an upper wall surface of a combustion chamber, and is used to ignite air-fuel mixture. Fuel injected from a port fuel injection valve is directed toward the center of the combustion chamber when the intake valve is open. The engine is configured to generate a tumble flow in a cylinder. A flow speed of gas around the ignition plug during ignition is controlled by changing a pattern of tumble flow between an ordinary first tumble flow pattern (engine speed range R1) and a different second tumble flow pattern (engine speed range R2) on the basis of an engine rotation speed. The tumble flow having the second pattern is generated by overlapping a fuel injection period of the port fuel injection valve with the open period of the intake valve (intake synchronous injection mode).
