摘要： An exhaust passage (2) of a diesel engine (1) is connected to an intake passage (3) via an exhaust gas recirculation passage (4) provided with an exhaust gas recirculation valve (6). A turbine (52) of a variable capacity turbocharger (50) is provided in the exhaust passage (2). The controller (41) controls the opening of the exhaust gas recirculation valve (6), and the opening of a nozzle (53) of the turbine (52). A controller (41) first calculates a target exhaust gas recirculation valve opening surface area based on a target exhaust gas recirculation flowrate, and controls the exhaust gas recirculation valve opening to the target exhaust gas recirculation valve opening surface area.

摘要： An intake pressure and exhaust pressure of an engine are predicted from a fresh air flowrate in a diesel engine comprising an exhaust gas recirculation system and a sensor for detecting the fresh air flowrate. A fault in the system is diagnosed based on the predicted intake pressure and exhaust pressure. Preferably, fault diagnosis in the exhaust gas recirculation system is based on a differential pressure between the intake pressure and exhaust pressure, or on a comparison of an estimated EGR rate and target EGR rate found from the intake pressure and exhaust pressure, without providing any special sensors. Smoke emission is also reduced by limiting the maximum fuel injection amount of the engine.

摘要： A diesel particulate filter (14) which traps particulate matter and a NOx trap catalyst (13) which traps nitrogen oxides are installed in series in an exhaust passage (10) of a diesel engine (1). A controller (21) calculates a particulate matter deposition amount in the diesel particulate filter (14) (S4). The controller (21), when the particulate matter deposition amount exceeds a first predetermined amount (PM2), prevents sharp increase of the particulate matter deposition amount by prohibiting rich spike where the oxygen concentration of the exhaust gas is controlled to a value corresponding to a rich air-fuel ratio in order to regenerate the NOx trap catalyst (13) (S301, S302, S306), and prevents the particulate matter deposition amount of the diesel particulate filter (14) from reaching a limit.

摘要： A fuel injection control device is configured to suppress the effect of pressure pulsation occurring inside the accumulator section of an engine due to a first fuel injection and thereby accurately control the fuel injection quantity in an engine configured to execute a plurality of fuel injections per cycle. When the fuel injection quantity for a second injection executed after a first injection is set, the fuel injection interval is detected and the fuel injection quantity is revised based on the fuel injection interval. The amount of time from the end of the first injection (e.g., a pilot injection) to the start of the second injection (e.g., a main injection) is used as the fuel injection interval.

摘要： An engine fuel injection control system including a particulate filter is configured to compare an accelerator request fuel injection quantity based on an accelerator depression amount to an air fuel ratio request fuel injection quantity determined based on a target air fuel ratio based on the engine operating condition. The engine fuel injection control system is configured to select the smaller of the accelerator request fuel injection quantity and the air fuel ratio request fuel injection quantity as a target fuel injection quantity. When the engine is operating in a low rotational speed region with full load, the target air fuel ratio is adjusted to a value substantially equal to the air fuel ratio that provides a maximum torque. Thus, the fuel is injected to achieve an air fuel ratio close to the stoichiometric air fuel ratio the torque performance and acceleration performance can be improved.

摘要： An exhaust gas cleaning system is provided that includes a particulate filter in an exhaust passage. The exhaust gas cleaning system is configured and arranged to determine an accumulation state of particulate matter in a particulate filter by obtaining a reference equivalent surface area of a passage inside the particulate filter based on a pressure difference between before and after the particulate filter, an exhaust gas flow rate, and a temperature of the exhaust gas passing through the particulate filter. The exhaust gas cleaning system is configured and arranged to obtain an adjusted equivalent surface area by adjusting the reference equivalent surface area based on a temperature of the particulate filter and the exhaust gas flow rate. Thus, an amount of particulate matter accumulated in a particulate filter of a diesel engine is accurately estimated without the estimation result being erroneously affected by the engine operating conditions.
