ABSTRACT:
A fuel injection characteristic detection apparatus is applied to a fuel feed system. The fuel feed system is configured to inject fuel into one of a cylinder, an intake passage, and an exhaust passage of an internal combustion engine by using a fuel injection valve. The fuel injection characteristic detection apparatus includes fuel pressure obtaining unit for successively obtaining pressure of fuel supplied to the fuel injection valve. The fuel injection characteristic detection apparatus further includes pulsation pattern storing unit for associating a pulsation pattern of fuel pressure, which accompanies an injection operation of the fuel injection valve, with at least a fuel injection mode and a fuel pressure level at a present time point and for storing the associated pulsation pattern in a storage medium.
