    摘要： An exhaust pipe is connected to an intake branch pipe downstream of a throttle valve by an EGR passage. An EGR control valve that controls an EGR gas amount is arranged in the EGR passage. An EGR catalyst is arranged in the EGR passage downstream of the EGR control valve. An ozone supply apparatus is provided which supplies ozone to oxidize and remove particulate matter. An ozone supply end of the ozone supply apparatus is connected to the EGR passage upstream of the EGR catalyst. If an EGR gas supply operation is being performed and an EGR catalyst temperature is within a set temperature range that is set beforehand, an ozone supply operation is performed. If the EGR gas supply operation is not being performed or the EGR catalyst temperature is outside of the set temperature range, the ozone supply operation is prohibited from being performed.

    摘要： A NOx occluding and reducing catalyst 20 is provided in an exhaust gas passage of an engine to occlude the NOx in the exhaust gas of a lean air-fuel ratio. The engine is provided with an injector for directly injecting the fuel into the combustion chamber, and the fuel fed by a fuel pump into a common rail with pressure is injected. The additive containing a sulfur-solidifying agent that forms a solid sulfate upon the reaction with sulfur in the fuel due to combustion, is injected into the common rail from a tank due to a pump, and is supplied into the combustion chamber through the injector together with the fuel. When the condition of the atmosphere of the NOx occluding and reducing catalyst is the one where the NOx in the exhaust gas is little absorbed, the ECU adjusts the discharge amount of the pump, and decreases the amount of the additive injected into the common rail or interrupts the injection. This decreases the consumption of the sulfur-solidifying agent.

    摘要： An object of this invention is to prevent components such as NOx and H2S being emitted when starting a vehicle and improve exhaust emissions by utilizing information of a navigation system. A navigation system mounted in the vehicle is connected to an ECU. The ECU predicts whether a stopping time of the internal combustion engine is near based on the current position and travel history of the vehicle obtained from the navigation system. When a stopping time is near, the ECU executes rich spike control prior to the stopping time to thereby perform a regeneration process of the NOx catalyst. Thus, NOx components or sulfur components remaining in the catalyst can be eliminated before stopping the internal combustion engine. Accordingly, even if warming up is performed when the engine is next started, emission of NOx or hydrogen sulfide can be avoided.

    摘要翻译： 本发明的目的在于防止在起动车辆时排出NOx，H2S等成分，利用导航系统的信息来改善废气排放。 安装在车辆中的导航系统连接到ECU。 ECU基于从导航系统获得的车辆的当前位置和行驶历史来预测内燃机的停止时间是否接近。 当停止时间接近时，ECU在停止时间之前执行丰富的尖峰控制，从而进行NOx催化剂的再生处理。 因此，在停止内燃机之前可以消除残留在催化剂中的NOx成分或硫成分。 因此，即使在发动机下一次起动时进行预热，也可以避免NOx或硫化氢的排放。
