Abstract
The invention provides a fuel injection control apparatus of an engine in which a temperature sensor for detecting an engine temperature is inexpensive and a wiring to a control unit is made unnecessary, thereby restricting a system cost low. A control unit () is integrally formed with a throttle chamber () corresponding to a peripheral device of an engine (), a temperature sensor () detecting an engine temperature is directly attached to a substrate () of the control unit (), and the temperature sensor () estimates an actual engine temperature on the basis of an engine peripheral temperature detected by the temperature sensor () by using a correlation data obtained by previously searching a correlation between the engine peripheral temperature detected by the temperature sensor () and the actual engine temperature under the same condition, thereby calculating a fuel increase amount and time for the increase amount necessary from a low temperature start to a warm-up finish.
