Abstract
When or just after an engine (1) is started, a starting switch (9) is turned on and a value is set in a just-after-starting counter in a CPU (114). The starting or just-after-starting state is detected. Fuel temperature and fuel properties are detected by a fuel properties sensor (16). The detected values are calculated in the CPU (114). Fuel temperature detection output is corrected, then a filter value or average value is calculated and stored in RAM (114b) in the CPU (114) and just after the engine is started, based on the stored value, driving of a bypass control valve (6) and an injector (12) is controlled and the fuel amount or air amount is controlled for the engine. Thereby, it is enable optimum fuel amount control when and just after an engine is started regardless of the differences in the fuel properties.
