DEVICE FOR DETECTING KNOCKING APPLICATIONS IN INTERNAL COMBUSTION ENGINES WITH A CONTROLLED IGNITION DEVICE BASED ON THE USE OF TEMPERATURE SENSORS

摘要

In a controlled ignition internal combustion engine, two temperature sensors, one of which is placed in the farthest position relative to the spark plug and the other in the vicinity of the spark plug in a cylinder, generate signals the difference of which is significant for the detection of the knock phenomenon. As the temperature differential of the two sensors exceeds a preselected magnitude, a warning signal may be delivered on the dashboard, or the controlled ignition system of the engine may receive a command for reducing the angle of advance of ignition until ordinary, non-knock conditions are restored for the engine.
