摘要： In a gas mixture temperature estimation method for an internal combustion engine, before a forefront portion of a gas mixture reaches an inner wall surface of the combustion chamber, the gas mixture temperature is calculated in accordance with a predetermined equation which is based on the assumption that no head exchange occurs between the gas mixture and cylinder interior gas which exists around the gas mixture without mixing with fuel. After the gas mixture forefront portion reaches the inner wall surface of the combustion chamber, the gas mixture temperature calculated in accordance with the equation is corrected in consideration of the quantity of heat transfer between the gas mixture and the cylinder interior gas and the quantity of heat transfer between the gas mixture and the wall.

摘要： The present apparatus calculates a mass ma (mass ratio ma/mf) of mixing-gas-forming cylinder interior gas, which is a portion of cylinder interior gas to be mixed with a forefront portion of injected fuel vapor having a mass of mf, on the basis of a predetermined empirical formula. Subsequently, under the assumption that heat exchange with the outside does not occur, the apparatus calculates an adiabatic gas mixture temperature Tmix of the gas mixture forefront portion on the basis of the heat quantity of the fuel vapor having a mass of mf and the heat quantity of the mixing-gas-forming cylinder interior gas having a mass of ma. Subsequently, in consideration of an amount of heat that the gas mixture forefront portion receives from peripheral cylinder interior gas mainly via a circumferential surface thereof, the apparatus estimates a final gas mixture temperature Tmixfin of the gas mixture forefront portion (i.e., the temperature of the gas mixture) in accordance with the equation Tmixfin=Tmix (1−Kex)+Ta Kex, where Ta represents cylinder interior gas temperature, and Kex represents a heat exchange coefficient (0

摘要： In a gas-mixture-nonuniformity acquisition apparatus for an internal combustion engine, the nonuniformity of fuel concentration within a gas mixture is acquired under the assumption that, in a process in which a cylinder interior gas taken into a combustion chamber of the engine and fuel injected into the combustion chamber mix together to form a gas mixture, a collision reaction repeatedly takes place within the gas mixture in such a manner that, due to collision of two gas volumes having different fuel mass ratios, respective portions of the two gas volumes mix together, and the mixed portions separate from the corresponding gas volumes and form a portion or the entirety of another gas volume having a fuel mass ratio different from those of the two gas volumes.

摘要： The NOx storage catalyst and the NOx selective reduction catalyst are arranged in the engine exhaust passage. In the engine low load operating region, a combustion is performed in the combustion chamber under a lean base air-fuel ratio and the air-fuel ratio in the combustion chamber is made rich when NOx should be released from the NOx storage catalyst. In the engine medium load operating region, the base air-fuel ratio is made smaller, a degree of richness of the air-fuel ratio is made smaller, and a period in which the air-fuel ratio is made rich is made shorter so that an amount of ammonia which is produced per unit time when the air-fuel ratio is made rich falls compared with the time of engine low load operation.

摘要： An exhaust purification system of an internal combustion engine, which includes: a silver-alumina-based catalyst, which is arranged in an engine exhaust system and, when an air-fuel ratio of exhaust gas is leaner than a stoichiometric air-fuel ratio, releases adsorbed NO2 at a first set temperature and adsorbed NO at a second set temperature, a secondary air feed passage configured to suppress a temperature rise of the silver-alumina-based catalyst; and an electronic control unit, that: controls the air flow through the secondary air feed passage to: when the silver-alumina-based catalyst has reached a third set temperature, suppress a temperature rise of the silver-alumina-based catalyst to maintain the silver-alumina-based catalyst near the third set temperature, and then lift the suppression of the temperature rise of the silver-alumina-based catalyst so that at least part of the NO adsorbed at the silver-alumina-based catalyst, is oxidized to NO2 to be adsorbed at the silver-alumina-based catalyst.
