摘要： A fuel injection control device for an engine including a cylinder injector and an air intake passage injector is provided. The device changes a fuel injection style, from a compression stroke cylinder injection by the cylinder injector which is executed from a predetermined instant immediately after the beginning of the cold start of engine until a predetermined period has passed, to the combination of an air intake passage injection by the air intake passage injector, an intake stroke cylinder injection and a compression stroke cylinder injection by the cylinder injector which is executed after the predetermined period has passed. During the cold start of engine, the favorable combustion stability is obtained by the compression stroke cylinder injection before the predetermined period has passed, and an amount of HC is reduced after the passage of the predetermined period, promoting warming-up of catalyst.

摘要： An apparatus for controlling a heater for heating an oxygen sensor provided in an exhaust gas flow passage of an internal combustion engine disposed in an automotive vehicle includes a detection circuit, a decision circuit and a power supply control circuit. The monitor circuit detects a driving condition parameter of the automotive vehicle. The decision circuit determines, from a driving condition represented by the driving condition parameter detected by the detecting circuit, whether or not a power supply control to the heater should be executed. The power supply control circuit supplies, during a predetermined period of time, the heater with an amount of power which is smaller than that to be supplied thereto in a normal driving condition when it is determined that the power supply control to the heater should be executed by the decision circuit so that a resistance value of said heater is controlled to a target resistance value.
