MULTIPLE IGNITION SYSTEM AND ELECTRONIC CONTROL SYSTEM FOR AN AUTOMOBILE ENGINE

摘要

PURPOSE: A device for electronic control and multiple ignition of a vehicle engine(internal combustion engine) is provided to carry out stable ignition by a small ignition energy (15mJ or less) even under the irregular condition of a mixer in a combustion chamber and expand a lean burn limit, thereby minimizing the energy loss. CONSTITUTION: A device for electronic control and multiple ignition of a vehicle engine(internal combustion engine) includes sensors(1) of an engine for outputting signals corresponding to states of an engine, an engine electronic control unit(2) for determining an optimum ignition condition for an ignition period and the number of ignition during the ignition period by carrying out detection, comparison and operation of the output signals from the sensors, and an ignition unit(3) for receiving the determined optimum ignition condition via an ignition period controller(2') and an ignition frequency controller(2"), wherein the ignition period controller and the ignition frequency controller are constituted separately or integrally with the electronic control unit, the ignition period controller has a variable range of 0.,1ms-26.67ms and the ignition frequency controller has a variable range of 500Hz-100,000Hz.
