摘要： When a direct injection type internal combustion engine is in an operating state, a fuel is split and jetted into a cylinder of the internal combustion engine and split injections are performed in a manner to make a ratio of a piston travel and an injection pulse width of split injection constant in a cycle whereby a rich mixture is not locally generated and a mixture in a cylinder of the internal combustion engine is put in a condition near stoichiometry. Also, when the internal combustion engine is in cold condition, a fuel is split and jetted and split injections are performed so that the ratio of the piston travel and the injection pulse width of split injections monotonously increases in a cycle.

摘要： A conventional technique performs valve close control of an EGR valve after an EGR-gas back flow is detected. Therefore, the conventional technique has a subject that, if an EGR-gas flow direction changes from forward flow to back flow, a back flow condition will last not only for a response delay time of a detector but also for the judgment time by calculation processing and the actuation time of the EGR control valve. There is provided a control apparatus of an EGR control valve, comprising: an EGR control valve which is provided in an exhaust gas recirculation passage to circulate exhaust gas of an combustion engine from an exhaust gas passage to an intake air passage; measurement means for measuring a flow rate of EGR gas flowing in the exhaust gas recirculation passage; and control means for receiving an input from the measurement means and closing the EGR control valve if the EGR-gas flow rate is smaller than a predetermined threshold value when the EGR gas is flowing from the exhaust side to the intake side of the internal combustion engine.

摘要： Fuel injection technology of an internal combustion engine is configured in such a manner that in a case where in inlet pipe interior of the engine is partitioned by a rectifying plate into upper and lower flow paths, a flow velocity at a center of the flow path on an upper side, and at a center of the flow path on a lower side is increased. Consequently, a flow velocity distribution of air in a cylinder diametrical direction of a valve head of an inlet valve becomes a peak value on both sides of the valve head center. Therefore, by impinging most of the injected fuel spray upon both sides of the center of the valve head, vaporization of the fuel spray can be performed with good efficiency.

摘要： An exhaust aftertreatment system comprises an injector for injecting urea water into an exhaust duct, and a denitration catalyst disposed downstream of the injector with respect to a flow of exhaust gas. The exhaust aftertreatment system reduces nitrogen oxides in the exhaust gas by the denitration catalyst while using ammonia produced from the urea water injected from the injector. The urea water is injected along a direction of the flow of the exhaust gas within the exhaust duct, and a porous plate is disposed in multiple stages in a space of the exhaust duct such that droplets of the injected urea water impinge against the porous plate before reaching a wall surface of the exhaust duct. A surface of the porous plate subjected to the impingement of the droplets is arranged to face downstream with respect to the flow of the exhaust gas. Deposition of the urea water is prevented by causing film boiling when the droplets impinge against the porous plate, and the urea water reflected by the porous plate is uniformly dispersed into the exhaust gas. Thus, the urea water is uniformly dispersed into the exhaust gas without increasing a pressure loss of the exhaust gas. The urea water is prevented from depositing on the wall surface and producing a precipitate in the form of a solid.

摘要： With a cylinder direct injection engine in which fuel is injected directly into combustion chambers and air-fuel mixture is guided by an air flow, it is difficult to secure combustion stability under low engine speed and low load conditions such as during idling. Furthermore, there are needs for improvement of emission characteristics and fuel economy in other operation modes as well. An engine according to the invention injects fuel while dividing the same in plural parts during a compression stroke. The first injection forms a lean air-fuel mixture around an ignition plug, and the second injection makes a flammable air-fuel mixture reach an area around the ignition plug. This ensures efficient stratified combustion and allows improvement in emission and fuel economy performance.
