摘要: A control apparatus for an internal combustion engine (10) includes intake valve control means (50). The internal combustion engine (10) includes a variable intake valve operating mechanism (66) that changes a valve opening characteristic of an intake valve (64), and rich combustion is performed in the internal combustion engine (10) to control an exhaust gas purification catalyst (24) disposed in an exhaust passage (18). The intake valve control means (50) controls the valve opening characteristic of the intake valve (64) to increase a flow rate of intake air in an early stage of an intake stroke when the rich combustion is performed, as compared to when non-rich combustion is performed.

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: 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.
