Изобретение предназначено дл диагностики двигател внутреннего сгорани путем определени момента начала воспламенени топлива в камере сгорани .The invention is intended to diagnose an internal combustion engine by determining the instant onset of ignition of the fuel in the combustion chamber.
Известны устройства дл диагностики двигател внутреннего сгорани , содержащие прозрачный элемент, соединенный через фотодиод с индикатором, например осциллографом .Devices for diagnosing an internal combustion engine are known, comprising a transparent element connected via a photodiode to an indicator, such as an oscilloscope.
Целью изобретени вл етс устранение вли ни вибрации двигател на результат измерени .The aim of the invention is to eliminate the influence of engine vibration on the measurement result.
Это достигаетс соединением прозрачного элемента с фотодиодом посредством гибкого световода.This is achieved by connecting the transparent element to the photodiode by means of a flexible light guide.
На чертеже изображено предлагаемое устройство .The drawing shows the proposed device.
Оно содержит прозрачный элемент 1, установленный в стенке цилиндра двигател 2 и присоединенный к фотодиоду 3 посредством гибкого световода 4. Фотодиод 3 включен в схему с усилителем посто нного тока 5 и осциллографом 6.It contains a transparent element 1 mounted in the cylinder wall of the engine 2 and connected to the photodiode 3 by means of a flexible light guide 4. Photodiode 3 is included in the circuit with a DC amplifier 5 and an oscilloscope 6.
Через прозрачный элемент 1 и световод 4 светоизлучение процесса сгорани топлива из камеры двигател поступает на фотодиод 3, где преобразуетс в изменение фототока. Фототок усиливаетс и регистрируетс осциллографом 6. Гибкий световод 4 исключает вли ние вибрации двигател на результат измерени и не требует охлаждени устройства.Through the transparent element 1 and the light guide 4, the light emission from the combustion process of the fuel from the engine chamber enters the photodiode 3, where it is converted into a change in the photocurrent. The photocurrent is amplified and recorded with an oscilloscope 6. Flexible light guide 4 eliminates the effect of motor vibration on the measurement result and does not require cooling the device.
Анализ регистрации осциллограмм позвол ет осуществить диагностику основных систем и механизмов двигател .Analysis of waveform recording allows diagnostics of the main systems and mechanisms of the engine.
