Abstract

The fuel jet controller capable of advancing initial detonation and improving start performance has crankshaft angle sensor to generate the crankshaft angle signal corresponding to the rotation position of the internal combustion engine; various sensors for detecting the motion state of the internal combustion engine; fuel jets set inside the cylinders to jet fuel in required amount; cylinder distinguishing unit to distinguish cylinders based on the angle signal to generate cylinder distinguishing signal; fuel jet controlling unit to drive jets in different cylinders based on the crankshaft angle signal, operation state and the cylinder distinguishing signal; and fuel jet amount correcting unit to correct the drive time of each fuel jet based on the crankshaft angle signal, operation state and the cylinder distinguishing signal.

Description

technical field [0001] The present invention relates to a fuel injection control device for an internal combustion engine, and more particularly to a fuel injection control device for an internal combustion engine that has an injector for each cylinder of the internal combustion engine and has a process of simultaneously injecting fuel to all cylinders at startup. Background technique [0002] Conventionally, there have been proposals for a fuel injection control device for an internal combustion engine that has an injector for each cylinder of the internal combustion engine and has a process of injecting fuel to all the cylinders simultaneously at the time of starting. In such a fuel injection control device, generally, a start mode includes a cylinder identification step and a start simultaneous injection step. [0003] Among the above two steps, the cylinder identification step is a step of identifying a cylinder to be ignited by using a crank angle sensor while starting ...
