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： The cylinders of an internal combustion engine are divided into at least two cylinder groups. First air-fuel ratio sensors (11, 12) are disposed in each exhaust branch pipe (5, 6) connected to the cylinder groups, and a second air-fuel ratio sensor (13) is disposed in a common exhaust pipe (7) upstream from the catalyst (10). When a vapor amount introduced into an intake passage (4) during purge control is determined, the vapor amount is determined during normal operation using the output values from the first air-fuel ratio sensors (11, 12) and the value of vapor amount learned during normal operation. During rich-lean operation, the vapor amount is determined using the output value from the second air-fuel ratio sensor (13) and the value of vapor amount learned during rich-lean operation. By doing this, the vapor amount introduced into the intake passage (4) when a switch is made from normal to rich-lean operation of the internal combustion engine is accurately determined.
