Fuel injection timing control system for IC engine prevents injection starting too late relative to crankshaft angle

摘要

From the motor operating conditions, e,g, motor speed and load,the system electronic control unit determines the amount of fuel to be injected and the time at which injection should start. It then compares this time with the maximum time by which injection should commence. If the time exceeds the time limit in the advance direction of the crankshaft the electronic control unit initiates injection at the time limit
