    • An internal combustion engine according to the present invention includes an exhaust treatment apparatus provided in an exhaust passage, and a burner apparatus provided upstream of the exhaust treatment apparatus to increase an exhaust temperature. The burner apparatus includes at least a fuel addition valve that allows fuel to be added into exhaust and ignition means for igniting the fuel added via the fuel addition valve. The fuel addition valve is driven open when fuel is added via the fuel addition valve. The amount of fuel added via the fuel addition valve per unit time is increased beyond a predetermined reference amount when the detected amount of intake air exceeds a predetermined threshold value. The probability of successful ignition by the ignition apparatus is increased, and a flame is prevented from being blown out. Thus, the burner apparatus can demonstrate sufficient ignition performance and sufficient combustion performance.
    • 根据本发明的内燃机包括设置在排气通道中的排气处理装置和设置在排气处理装置上游以增加排气温度的燃烧器装置。 燃烧器装置至少包括能够将燃料添加到排气中的燃料添加阀和用于点燃通过燃料添加阀添加的燃料的点火装置。 当通过燃油添加阀添加燃料时,燃油添加阀被打开。 当检测到的进气量超过预定阈值时,每单位时间通过燃料添加阀添加的燃料量增加超过预定参考量。 通过点火装置成功点火的概率增加,并且防止火焰被吹出。 因此,燃烧器装置可以证明足够的点火性能和足够的燃烧性能。

    • An EGR control apparatus for an internal combustion engine, which is capable of properly controlling an inert gas amount of two types of EGR gas supplied to cylinders of the engine via two paths different from each other, thereby making it possible to ensure a stable combustion state, reduced exhaust emissions, and improve operability. The EGR control apparatus includes low-pressure and high-pressure EGR devices, and an ECU. The ECU controls the low-pressure and high-pressure EGR gas amounts according to engine speed and demanded torque, and when a combination of engine speed and demanded torque is in a predetermined region, the low-pressure and high-pressure EGR gas amounts are controlled such that inert gas in low-pressure EGR gas exceeds in amount inert gas in high-pressure EGR gas, and the former more exceeds the latter as engine speed is higher or demanded torque is larger.
    • 一种用于内燃机的EGR控制装置,其能够通过彼此不同的两条路径适当地控制供给到发动机的气缸的两种EGR气体的惰性气体量,从而可以确保稳定的燃烧状态 ,减少废气排放,提高可操作性。 EGR控制装置包括低压和高压EGR装置和ECU。 ECU根据发动机转速和要求转矩控制低压高压EGR气体量,当发动机转速和要求转矩的组合处于规定区域时,低压高压EGR气体量为 控制使得低压EGR气体中的惰性气体在高压EGR气体中超过惰性气体量,并且当发动机转速较高或要求转矩较大时,前者大于后者。
