摘要：PURPOSE:To reduce the storage capacity of memory in a control device for setting the combustion of an engine in a predetermined condition, by storing a learning value of each engine cylinder in the memory in the form of a difference from that of a specific engine. CONSTITUTION:A final control amount determining means receives output signals from a basic control amount determined means, a feedback compensating amount determining means for each engine cylinder, a learning value storage means for a specific engine cylinder and learning value storage means for other engine cylinders, and delivers a control signal to an engine combustion control means (an ignition device and a fuel injection device) to control the burning condition of the engine. Since the differences in knocking limitation among the engine cylinders are slight, a learning compensating value for the specific engine cylinder is directly stored in memory while a learning map exhibiting a learning value for every operating range has a storage capacity of two bytes for the specific engine cylinder but of one byte for every other engine cylinder. Therefore, the storage capacity is reduce as a whole, thereby it is possible to aim at reducing the cost of the engine control device, at making the same lightweight and so forth.
