摘要： 과급기관에서, 애트킨슨(Atkinson)싸이클화에 의한 열효율의 향상과 더불어, 충전효율의 향상, 과급기효율의 향상 및 캠설계의 자유도 증대화를 기하는 제어방법으로서, 특히 과급기를 갖는 내연기관의 밸브개폐 제어방법에 관한 것이다. 유효압축비를 낮춰줌으로써 실린더 내압을 지나치게 높이지 않고서도 열효율을 향상시킬 수가 있다. 바람직하기로는 유효압축비/팽창비가 0.5 ~ 0.9의 범위에 들도록 배기밸브 재개방시기를 설정한다. 또, 시동시 또는 저부하운전시에는 압축행정전기에서 배기밸브를 일시적으로 열리지 않도록 하고, 재부하운전시에 상기 배기밸브의 재개방에 의한 애트킨슨싸이클화가 도모될 수 있게 된다.

摘要： A method of controlling an internal combustion engine, in which engine operation with a reduced number of cylinders is controlled according to an idling speed after starting the engine to thereby minimize discharge of white smoke during a time lag for temperature equilibrium immediately after a cold start. The method uses a coolant temperature detection means (10) for detecting the temperature of the coolant of the internal combustion engine (1), an engine speed detection means (12) for detecting the speed of the engine, and control means (5) for controlling operation of the engine according to the temperature of the coolant and the engine speed. When the engine is determined to be in a cold start, engine operation with a reduced number of cylinders is started, and in this engine operation, fuel is injected into the cylinders for a predetermined time period after the speed of the engine reaches a predetermined level after the start of the engine. ® KIPO & WIPO 2009

摘要： A fuel injection control device for a diesel engine controls a first fuel injection timing to reduce white smoke produced in a large amount immediately after the start of the engine. The fuel injection control device has a high-pressure pump, a common rail for storing fuel raised to high pressure, an injector for injecting the fuel into a combustion chamber, and control means. In starting the engine, in order that the pressure in the common rail becomes a set pressure, the fuel injection control device controls fuel injection such that, when an engine start switch is turned on, the fuel is injected after the engine is cranked without injecting the fuel for a predetermined time period.

摘要： A method of controlling a premix compression self-igniting internal combustion engine in which intake air and fuel are mixed in advance in a combustion chamber and the mixture is self-ignited by compression. Optimal self-ignition timing in accordance with operation condition can be obtained with the method for improved combustion. An exhaust valve (9) is temporarily reopened during a compression stroke, and timing of closing the reopened valve is variable, so that timing of the closure is varied for an effective compression ratio at which optimal self-igniting timing can be obtained at each operation region. A valve closure timing map for the exhaust valve reopening is formed from an engine speed and load, and closure timing of the exhaust valve (9) is varied based on the map. The closure timing of the exhaust valve (9) is varied such that an effective compression ratio is increased in an operation region where the load is small, and the ratio is reduced with an increase in the load.
