A fuel injection control apparatus for an internal combustion engine capable of making correctly or properly decision as to acceleration and deceleration of engine without fail on the basis of magnitude of change in the intake air quantity while excluding erroneous deceleration or acceleration decision due to overshoot or undershoot in the intake air quantity to thereby allow the exhaust gas air-fuel ratio to be maintained at least close to a stoichiometric ratio. The apparatus includes an electronic control unit comprised of a throttle-acceleration decision module, a fuel injection decreasing module and a fuel injection increasing module. When acceleration is determined by the throttle-acceleration decision module, a deceleration decision reference value used by the fuel injection decreasing module is set to a value greater than a normal value for a predetermined period after the decision of acceleration, while when deceleration is determined, an acceleration decision reference value for the fuel injection increasing module is set to a value greater than a normal value for a predetermined period after the decision of deceleration. The acceleration decision reference value and the deceleration reference value are compared with magnitude of change in the amount of intake air by the fuel increasing module and the fuel decreasing means for deciding the acceleration and the deceleration, respectively.

A control method is provided for an engine for a vehicle. The engine is arranged in association with a fluid coupling having a clutch. According to the control method, the state of engagement of the clutch is first detected. In the next step, it is determined whether or not the vehicle is in a predetermined decelerated operation state. When the clutch has been detected to be in a predetermined state of engagement in the clutch engagement state detection step and in addition, the vehicle has been determined to be in the predetermined decelerated operation state in the decelerated operation state determination step, an output of the engine is increased in the subsequent step.

An apparatus for controlling the supply of air to a burner used to recombust diesel particulates trapped in a ceramic filter. The inventive control apparatus includes an exhaust bypass line that bypasses the filter, an air supply line leading to a burner associated with the filter, a flow control valve that adjusts the cross-sectional area for the air flow in the air supply line, a relief valve that maintains a constant difference between pressures at points upstream and downstream of the flow control valve, and a control unit that controls the degree of opening of the flow control valve. With the invention, precise control over the flow rate of secondary air is ensured.
