Title:
燃料噴射状態検出装置
Document Type and Number:
Japanese Patent JP4835715
Kind Code:
B2
Abstract:
A fuel injection detecting device computes an actual fuel-injection-start timing based on a falling waveform of the fuel pressure detected by a fuel sensor during a period in which the fuel pressure decreases due to a fuel injection rate increase. The falling waveform is modeled by a modeling formula. A reference pressure is substituted into the modeling formula, whereby a timing is obtained as the fuel-injection-start timing.
