摘要: A diesel engine has a fuel injection nozzle to which pressurized fuel is supplied from a pump. The nozzle has a pressure sensor detecting the fuel pressure and a lift sensor sensing a lift magnitude of a needle valve. An electronic control unit (ECU) computes a variation ratio of the fuel pressure value which is measured by the pressure sensor. The ECU computes a non-increasing point in an increasing part of variation ratio and judges the point to be a timing for starting the fuel injection of the nozzle. The ECU also computes the actual fuel injection amount in accordance with the fuel injection timing as well as the fuel pressure and the lift amount of the needle valve both at the various points. The ECU controls the actual injection amount to be identical to a target fuel injection amount.

摘要: In an internal combustion engine, a first exhaust passage and second exhaust passage branched from an exhaust passage are provided. An NOx storing reduction catalyst and a particulate filter are arranged in each exhaust passage. For example, when NOx should be released from the NOx storing reduction catalyst in the first exhaust passage, fuel is added from a fuel addition valve in the state with exhaust gas allowed to flow into only the first exhaust passage, while when the added fuel sticks to the NOx storing reduction catalyst, the first exhaust control valve is temporarily closed and the exhaust gas is made a rich air-fuel ratio.
