Patent ID: 8055434

Claim:
A fuel injection control system, comprising: a fuel injection device for an engine; a sensor unit for detecting data for calculating an amount of fuel to be injected by the fuel injection device; a control unit for calculating the amount of fuel to be injected by the fuel injection device based on the data detected by the sensor unit; a power generation unit which is driven in accordance with the engine and which supplies electric power to the fuel injection device and the control unit; and a start device for starting the engine; wherein the control unit is configured to acquire the data from the sensor unit at a first sampling rate before the engine is started and a second sampling rate after the engine is started, wherein the first sampling rate is higher than the second sampling rate, wherein the control unit includes an averaging process module which performs an averaging process on the data acquired from the sensor unit, and wherein the averaging process module is configured to calculate an averaging process value which carries a greater degree of contribution from the most recently acquired data from the sensor unit in a predetermined period before starting the engine than after starting the engine.
