Abstract
Microprocessor system for studying the distribution of breakdown voltage values of the ignition system
Incoming article date: 28.03.2018The authors developed an algorithm, a microprocessor system for studying the distribution of values of breakdown voltages in the gap of the spark plug. The microprocessor system includes capacitive voltage dividers and a device for processing and outputting information. The device for processing and outputting information consists of the following main blocks: peak detector, microcontroller and LCD indicator. The field studies of the microprocessor system were carried out at idle speed with the minimum engine speed of the crankshaft. A histogram of the distribution of the values of the breakdown voltage in the interelectrode gap of the spark plug is obtained. The application of this system not only in the laboratory environment, but also on the car can provide valuable information about malfunctions in the ignition system and assess the dependence of the intercycle non-identity of the engine working process on the variations of the breakdown voltage
