PROBLEM TO BE SOLVED: To capture a fuel characteristic such as fuel temperature and/or compressibility without providing an additional sensor by supplying a signal indicating the fuel characteristic on the basis of a pressure signal. SOLUTION: The rotating speed, a travel pedal position and a pressure signal on fuel to be injected are improtant as the input quantity of the whole device. An output signal of a rotating speed sensor 25 is therefore supplied to the corresponding input side of a fuel quantity control stage 23 and an injection start control stage 24, and a travel pedal position signal is supplied to the fuel quantity control stage 23 by a sensor 26. In addition, a pressure signal is sent to a signal processing stage 29 by a pressure sensor 27 for measuring fuel pressure. The signal processing stage 29 has two output sides 30, 31 for the injected fuel quantity and injection start time. These output sides 30, 31 are therefore connected to an exhaust gas feedback control stage 15, the fuel quantity control stage 23 and the injection start control stage 24. |
