    • 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。
