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.

摘要： A method for controlling an internal combustion engine, in which a traveling with reduced cylinders is controlled according to the idle-speed after the engine starting, so as to restrain the discharge of white smokes at the time lag for temperature equilibration soon after a cold starting. The method comprises a coolant water temperature detecting means 10 for detecting the coolant water temperature in the internal combustion engine 1, a rotation speed detecting means 12 for detecting the rotation speed of the internal combustion engine 1 and a control means for controlling the operation of the internal combustion engine 1 in accordance with the coolant water temperature and the rotation speed. When the internal combustion engine is evaluated that it is at the cold starting and the rotation speed reaches the predetermined rotation speed after the engine starting, a traveling with reduces cylinders is performed, which reduces the number of cylinders injecting fuels for a certain period of time.

摘要： A fuel injection control device for a diesel engine controls the first fuel injection timing so as to reduce the amount of white smoke generated in large amounts immediately after starting an engine. The fuel injection control device for the diesel engine comprises a high-pressure pump, a common rail for accumulating a highly-pressured fuel, injectors for injecting the fuel into a combustion chamber and a control means. Due to the fuel injection control device for the diesel engine, the fuel injection is performed after the cranking, without injecting the fuel for a certain period of time after an engine starting switch is turned on so that the pressure in the common rail becomes a set value.

摘要： Provided is an engine which can certainly be started even in a very-low-temperature range. The engine comprises a plurality of cylinders, a fuel injection device which injects fuel to the respective cylinders, a combustion chamber temperature calculation means which calculates a temperature in a combustion chamber, a control means which starts the engine by normal operation which injects the fuel to all the cylinders by the fuel injection device or reduced-cylinder operation which injects the fuel to only specified cylinders by the fuel injection device. When starting the engine, the control means controls the engine to conduct the normal operation when the temperature in the combustion chamber calculated by the combustion chamber temperature calculation means is in the very-low-temperature range and to conduct the reduced-cylinder operation when the temperature in the combustion chamber comes into a low-temperature range.
