Technical Examples
A pressure pattern estimation device of a fuel injection controller of an engine estimates a pressure transition of fuel in a common rail. A surplus pressure range calculation device of the fuel injection controller calculates a surplus pressure range in which pressure pattern data provided by the pressure pattern estimation device exceeds a target common rail pressure. The fuel injection controller releases the common rail pressure to a lower-pressure side by operating a pressure reduction valve of the common rail to eliminate the surplus pressure range calculated by the surplus pressure range calculation device. Thus, the common rail pressure (injection pressure) during an injection period is smoothed.
