摘要： A control system for an engine comprises an operation range judging section that judges an operation range assumed by the engine, a variable cycle operating section that switches the operation of the engine between 4-cycle operation and a different cycle operation in accordance with a judgment made by the operation range judging section, the different cycle operation being of an operation whose cycle is different from 4-cycle, and an intermediate variable cycle operating section that allows part of the cylinders to carry out 4-cycle operation and remaining part of the cylinders to carry out the different cycle operation when the operation range judging section judges that the engine is under an intermediate operation range assumed between an operation range provided by 4-cycle operation and an operation range provided by the different cycle operation.

摘要： An engine employs a dual mode combustion process including a first combustion mode for light loads utilizing premixed charge forced auto ignition (PCFA) wherein a pulse jet of reacting fuel mixture from a prechamber mixes with an ultra dilute premixed fuel-air charge in a main chamber, causing rapidly expanding combustion that ignites the remaining ultra dilute mixture by compression ignition. This improves efficiency, allows combustion phasing control and reduced NOx emissions. For higher speeds and loads, a conventional second combustion mode is utilized wherein a strong premixed mixture is ignited conventionally with spark ignition and/or pulse jet ignition. Cylinder pressures which would result from compression ignition at the higher speeds and loads are thus reduced providing overall engine operation with reduced emissions, improved fuel economy, and reduced noise through improved control of the combustion process.

摘要： A combustion control apparatus for an engine having a variable valve timing mechanism capable of varying valve timings of an exhaust valve and an intake valve establishes a combustion mode to either of following three modes, a four-cycle compression ignition combustion mode at a low and medium load area, a two-cycle spark ignition combustion mode at a high load area, and a four-cycle spark ignition combustion mode at a high speed area. When the combustion mode is established to the compression ignition combustion mode, the apparatus establishes the valve timings of the exhaust and intake valves so as to form a negative overlap period in which both exhaust and intake valves concurrently close in the neighborhood of the exhaust top dead center (TDC).

摘要： The invention relates to a method of operating a direct injection internal combustion engine operated on both spark-ignitable and autoignitable fuel, more specifically on gasoline, wherein the operational range of the engine is allocated autoignition ranges and spark-ignition ranges, an at least nearly homogeneous fuel-air mixture being produced in the combustion chamber in autoignition ranges, a high compression ratio suitable for spontaneous ignition of the fuel being provided and the combustion in the autoignition range being mostly initiated by spontaneous ignition, and wherein, in the ranges of spark ignition, combustion is initiated by spark ignition of said air-fuel mixture and a spark ignition range is assigned to the full load range and an autoignition range assigned to at least part of the part load range and wherein the effective compression ratio is lowered in spark ignition ranges and combustion controlled by regulating the residual gas content in the ranges of spontaneous ignition. In order to improve the exhaust emission quality while keeping efficiency high, the operational range of the engine is allocated two-stroke and four-stroke operational ranges and the internal combustion engine is operated on a two-stroke cycle in the ranges operating in the two-stroke mode and on a four-stroke cycle in the ranges operating in the four-stroke mode.

摘要： A piston internal-combustion engine has a control system for controlling the number of strokes of the combustion process taking place inside a combustion space. As a function of operating parameters, the control system controls the engine operating process such that the process has a variable cycle of at least four strokes. A pushing of a charge out of a combustion space of the piston internal-combustion engine does not take place before one or several operating parameters have reached one defined limit value, respectively.

摘要： An internal combustion engine and a method for operating the multi-stroke combustion engine is disclosed. The engine is provided with individual variably controlled inlet and outlet valves in each cylinder. Operation of the engine involves controlling the inlet and outlet valves so that the opening and closing of the valves are adapted to a second stroke mode that is different from a first stroke mode in which the engine is presently running. Fuel injected into the cylinders is controlled so that it is injected prior to an expansion stroke. The transition from the first stroke mode to the second stroke mode occurs independent of the operating condition of the engine throughout the entire operating range of the engine.

摘要： A method is provided for converting a conventional four stroke internal combustion engine having four cylinders into a two stroke engine. The camshaft assembly including the camshaft having cams thereon and the drive assembly which couples the camshaft to the crankshaft are replaced with a modified camshaft assembly such that the inlet and exhaust valves are each opened once per revolution of the camshaft. The resulting two stroke engine includes two pairs of pistons, each pair of pistons having a first and second piston which are fired synchronously. The pairs of pistons being spaced 180 degrees apart such that two pistons are fired synchronously for every half rotation of the crankshaft.

摘要： A two-cycle action cam having two protruding parts 1a and 1b and a four-cycle action cam 3 having one protruding part 3a are selectively used by a cam change mechanism 46i. The two-cycle action cam 1 effects opening of the inlet and exhaust valves once per revolution of the crankshaft and the four-cycle action cam 3 effects opening of the inlet and exhaust valves once per two revolutions of the crankshaft. The four-cycle action is selected when the engine is in the low revolving speed and running at a low load and the two-cycle action is otherwise selected.
