초록 ▼

An ignition timing control system in a spark ignition type internal combustion engine which has multiple cylinders, wherein ignition pulses generated in accordance with the operating condition of the engine are delayed in response to knockings detected to control the ignition timings to the optimum advance conditions free from knockings, has such characteristic features that respective cylinders of the engine are controlled in ignition timing independently of one another, a detected knocking signal is divided for the respective cylinders and only the ignition pulses corresponding to the cylinders of knocking is delayed so that the optimum advance conditions for the respective cylinders can be obtained.

대표청구항 ▼

An ignition timing control system in a spark ignition type internal combustion engine having multiple cylinders, comprising: at least one knocking detecting means for detecting engine vibrations and emitting a vibration signal; a knocking determining means for comparing the level of said vibration signal with a reference level and emitting a knocking signal when the level of said vibration signal exceeds said reference level; a timing signal generating means for emitting a timing signal having one pulse at each predetermined crank angle; a knocking feedback control means in which knocking feedback control circuits equal in number to cylinders of the engine are arranged in parallel to one another, for operating a correction ignition advance angle in response to said knocking signal and emitting a correction ignition signal; a distributor means for selecting one knocking feedback control circuit of said knocking feedback control means in accordance with the number of pulses of said timing signal and supplying said knocking signal to the knocking feedback control circuit thus selected, said distributor means comprising a counter provided with output terminals equal in number to the cylinders of the engine and supplied to an input terminal thereof with said timing signal for successively emitting control signals from the output terminals between two pulses of said timing signal, analog switches having respective input and output terminals equal in number to the cylinders of the engine and connected in parallel to said knocking determining means in such a manner that said knocking signal is supplied to the respective input terminals with said analog switches adapted to be successively turned on by said control signals, and delaying circuits equal in number to the cylinders of the engine and connected to the output terminals of said analog switches, respectively, for delaying the knocking signal, which has pressed through said analog switch, for a predetermined period of time and supplying said knocking signal to each of said knocking feedback control circuits; an integrator means for selecting one knocking feedback control circuit of said knocking feedback control means in accordance with the number of pulses of said timing signal and allowing said correction ignition signal of the knocking feedback control circuit thus selected to pass therethrough; an ignition timing operating means for operating an actual ignition timing in accordance with said correction ignition signal thus passed through said integrator means and a basic ignition timing; and a switching means for controlling an ignition timing in response to an output signal from said ignition timing operating means.
