The METZGER brand Sensor, exhaust gas temperature is needed in order to monitor the situation in the cylinders.

The main reason for the rise in temperature is the poor mixture. The main consequence of exceeding the threshold temperature is detonation.

In addition, in turbo engines, an increase in the threshold temperature also adversely affects the turbine and leads to its overheating, oil coking, etc. Temperatures up to 900-950 degrees are considered normal.

The principle of the sensor usage

The sensor itself crashes into the exhaust manifold. A hole is drilled, a thread is cut and the sensor is screwed in. Typically, the thread is tapered for better sensor fixation. There are several opinions about the installation site. Some believe that it is better to install it in the rut of the hottest cylinder, others - in the place where all the collectors come together.

When installing the sensor in turbo motors, you must try to prevent chips from getting inside the manifold, because they can damage the turbine. To do this, it is best to drill and thread with the engine running.
