摘要： An opening and closing condition of a thermostat is optimized. In a cooling system for an internal combustion engine in which a cooling water, in which its specific heat becomes larger at a predetermined temperature than at other temperatures, is caused to circulates through a cooling water passage, there are provided a radiator, a bypass passage that bypasses the radiator, and a thermostat that interrupts the circulation of the cooling water to the radiator and circulates the cooling water to the bypass passage when it closes, and circulates the cooling water to at least the radiator when it opens, wherein the thermostat is set to open at the time when the temperature of the cooling water is higher than a predetermined temperature.

摘要： Disclosed is a technology that enables better reduction of NOx stored in an NOx catalyst in an exhaust gas purification system for an internal combustion engine. When NOx stored in an NOx catalyst is to be reduced, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to a target air-fuel ratio by decreasing the air-fuel ratio of the exhaust gas discharged from the internal combustion engine. In doing so, if the temperature of the NOx catalyst is not lower than a specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to the target air-fuel ratio while bringing the combustion state into low temperature combustion. On the other hand, if the temperature of the NOx catalyst is lower than the specific temperature, the air-fuel ratio of the ambient atmosphere around the NOx catalyst is decreased to the target air-fuel ratio while decreasing the quantity of EGR gas in a cylinder so that the amount of generated smoke is kept within an allowable range.

摘要： During a rich spike control for an exhaust gas purification system for an internal combustion engine, a base air-fuel ratio AFb is decreased in a range where a combustion variation ΔCC does not exceed a permissible limit ΔCCL (S108). When the combustion variation ΔCC exceeds the permissible limit ΔCCL, the spike base air-fuel ratio AFbs is increased (S213). When the torque decrease amount ΔTD is above the permissible value ΔTDL, the spike base air-fuel ratio AFbs is decreased (S215). When the combustion variation ΔCC is above the permissible limit ΔCCL, and the torque decrease amount ΔTD is above the permissible value ΔTDL, the spike base air-fuel ratio AFbs is increased, and a fuel discharge time number EN is increased (S216).
