摘要： PROBLEM TO BE SOLVED: To effectively suppress the generation of an unburned combustible content (HC) at the low-temperature start of an internal combustion engine.SOLUTION: A control device (114) of an internal combustion engine (100) corrects a fuel injection timing using a correction value set according to cooling water temperature when the cooling water temperature is equal to or lower than a preset first temperature and starts to cool cooling water by a radiator (103) when the cooling water temperature has reached a second temperature. Specifically, the control device estimates a warm-up completion timing based on a temperature change in the cooling water to change the setting of the first temperature so as to get nearer to the warm-up completion timing estimated.

摘要： PROBLEM TO BE SOLVED: To provide a premixed compression self-ignition engine which reduces generation of knocking and generation of NOX, while achieving an extremely high thermal efficiency by increasing the compression ratio, and also to provide a method of controlling the same. SOLUTION: In the premixed compression self-ignition engine, the premixed air in which a fuel and air are mixed is compressed in a combustion chamber 3 and self-ignited and burned. The excess air ratio is 2.5-3.0, and the temperature of the supply air is 80°C or lower, or preferably about 40°C. The combustion in the combustion chamber is performed slowly, and the period of heat generation is slowed to 20-40°CA. The slow combustion prevents knocking, and as the combustion temperature is lowered, generation of NOX is significantly reduced. As the combustion is slowly performed, the density of oxygen in the premixed gas guided into the combustion chamber 3 is 17% or lower by circulating burned exhaust gas in the premixed gas, and a combustion inhibitor is added to the premixed gas.

摘要： PROBLEM TO BE SOLVED: To prevent the release of a great amount of unburned HC components to the outside before a front stage oxidation catalyst reaches its activating temperature after early post injection.
SOLUTION: The throttle opening of a variable throttle mechanism 77 provided in an oil passage 72 is reduced or a set value for a hydraulic pressure level detected by a hydraulic sensor 78 provided downstream of the variable throttle mechanism 77 is increased to increase the motive power of an oil circulation pump 74 before starting early post injection. This increases the load of a diesel engine 10 and increases the temperature rise gradient of exhaust gas in the temperature rise stage of the front stage oxidation catalyst to suppress the release of unburned HC components to the outside before the front stage oxidation catalyst 50 reaches its activating temperature.
