    摘要: An ECU (100) includes: a differential pressure detecting unit (115) that detects a filter differential pressure (ΔPA) obtained by subtracting a pressure downstream of a DPF (22) from a pressure upstream of the DPF (22); a deposition amount estimating unit (116) that estimates an amount of deposition (QP) of PM trapped in the DPF (22) on the basis of the filter differential pressure (ΔPA); an excessive deposition determination unit (118) that determines that the amount of deposition of PM trapped in the DPF (22) is abnormal when the amount of deposition (QP) of PM, estimated by the deposition amount estimating unit (116), is larger than or equal to a preset excessive deposition determination value (QPth); a vaporization determination unit (113) that determines whether moisture absorbed in the DPF (22) has vaporized; and a prohibiting unit (114) that prohibits the deposition amount estimating unit (116) from estimating the amount of deposition (QP) when the vaporization determination unit (113) determines that moisture absorbed in the DPF (22) has not vaporized yet.

    摘要: The invention relates to an internal combustion engine (1), comprising at least one combustion chamber (2) and an exhaust gas system (3) arranged on an exhaust gas outlet channel (5), the exhaust gas system having at least one secondary air injection device (4) for injecting secondary air into the exhaust gas system (3) between the combustion chamber (2) and an exhaust emission control system (5) arranged in the exhaust gas system (3), wherein during operation of the internal combustion engine (1), a residual gas content in the combustion chamber (2) can be changed, and a secondary air injection point (4') on the exhaust gas system (3) is arranged so far from the combustion chamber (2) that injected secondary air flows back into the exhaust gas outlet channel (5) due to backflowing exhaust gas in the exhaust gas system (3) but does not flow back into the combustion chamber (2). The embodiment according to the invention makes it possible to comply with SULEV emissions limits even for engines having many combustion chambers and/or exhaust gas turbochargers, for which a SULEV certification previously seemed impossible.

    摘要: An engine ECU executes a program including the step (S100) of detecting an engine coolant temperature (THW), the step (S120) of selecting a map for a warm state as the map for calculating a fuel injection ratio (or a DI ratio) (r) when the engine coolant temperature (THW) is equal to or higher than a temperature threshold value (THW(TH)) (YES in S110), the step (S130) of selecting a map for a cold state as the map for calculating the fuel injection ratio (or the DI ratio) (r) when the engine coolant temperature (THW) is lower than the temperature threshold value (THW(TH)) (NO in S110), and the step (S140) of calculating the fuel injection ratio between the in-cylinder injector and the intake manifold injector (or the DI ratio) (r) based on the engine speed, load factor, and the selected map.

    摘要: The present invention is an installation of an emergency starting switching device and/or direct current boosted boost circuit device. When the power of the starting battery is insufficient, the electric energy of the auxiliary battery is used to drive the starting motor in order to start the engine by operating the emergency starting switching device. And when the engine is started, the voltage of the ignition device or the fuel injection device is stepped up to strengthen its starting capability by means of a voltage boost by the direct current boosted boost circuit device.
