摘要： High exhaust gas temperatures whereby sulfur is removed from a lean NOx traps simultaneously with regeneration of a Diesel particulate filter is provided by alternating engine operation in respectively defined lean and rich combustion modes. The duration and frequency of the respective lean and rich operating modes, as well as the air/fuel ratio during the respective modes, are preferably controlled by the sensed temperature of the lean NOx trap substrate.

摘要： Combustion control of a diesel engine is achieved, such that the engine has a monotonic relation between intake manifold pressure and engine torque. For a given engine speed, fuel injection parameters are primarily determined by intake manifold pressure. However, the determination of the fuel injection parameters is also secondarily based on correction factors such as oxygen concentration, intake manifold temperature, and coolant temperature. In effect, the fuel injection parameters reflect the in-cylinder gas mass.

摘要： A control system for an internal combustion engine, which is capable of optimally controlling fuel injection by an injector even in a transient state of the engine. An ECU 2 of the engine provided with an EGR system (14) controls the amount (Fa) of air drawn into cylinders (3a) via an intake system (4). An air flow sensor (27) detects the intake air amount (Fa). The ECU 2 estimates a flow rate (Fe_hat) of EGR gases according to response delay of recirculation of the EGR gases by the EGR system (14), estimates the amount (mo2) of oxygen existing in the cylinder (3a), based on the detected intake air amount (Fa) and the estimated flow rate (Fe_hat) of the EGR gases, determines a fuel injection parameter (Q*) based on the engine speed (Ne) and the estimated in-cylinder oxygen amount (mo2), and controls an injector (6) based on the determined fuel injection parameter (Q*).
