Abstract

FIELD: engine engineering. SUBSTANCE: ion current that flows through electrodes of a spark plug is measured. Alternative voltage is generated in the primary winding of an ignition coil when control pulses are absent. Ion current in the secondary winding of the ignition coil is detected, e.g. with a synchronic detector. To apply the method the ignition system should be composed of control electronic unit, electronic switch and individual ignition coils for each spark plug. EFFECT: enhanced reliability. 4 cl, 6 dwg

Изобретение относится к двигателестроению и может использоваться в системах зажигания двигателей внутреннего сгорания, в частности, автомобилей. Целью изобретения является повышение надежности системы зажигания двигателя внутреннего сгорания, снабженной устройством определения нарушений процесса сгорания в цилиндре двигателя внутреннего сгорания. Для определения нарушения процесса сгорания в цилиндре двигателя внутреннего сгорания измеряют ионный ток, протекающий через электроды свечи зажигания. Способ отличается от известных способов тем, что в первичной обмотке катушки зажигания во время отсутствия управляющих импульсов зажигания генерируют переменное напряжение, а ионный ток во вторичной обмотке катушки зажигания детектируют, например, синхронным детектором. Способ может быть реализован в системе зажигания ДВС, содержащей электронный блок управления, электронный ключ и индивидуальные катушки зажигания для каждой свечи зажигания. Достоинством данного способа является возможность интегрального исполнения устройства для определения нарушений процесса сгорания в цилиндре ДВС, что позволяет уменьшить габариты устройства и повысить надежность системы зажигания.The invention relates to engine building and can be used in ignition systems of internal combustion engines, in particular, automobiles. The aim of the invention is to increase the reliability of the ignition system of an internal combustion engine, equipped with a device for determining violations of the combustion process in the cylinder of an internal combustion engine. To determine the violation of the combustion process in the cylinder of an internal combustion engine, the ion current flowing through the electrodes of the spark plug is measured. The method differs from the known methods in that an alternating voltage is generated in the primary winding of the ignition coil during the absence of control ignition pulses, and the ion current in the secondary winding of the ignition coil is detected, for example, by a synchronous detector. The method can be implemented in an internal combustion engine ignition system comprising an electronic control unit, an electronic key and individual ignition coils for each spark plug. The advantage of this method is the possibility of integral design of the device for determining violations of the combustion process in the engine cylinder, which allows to reduce the dimensions of the device and increase the reliability of the ignition system.
