With these sensors, you can measure the temperature of the exhaust or manifold.
The temperature of the exhaust gas is also a measure of the mixing ratio. Of course, it is not possible to measure directly inside the cylinder, therefore the sensor is placed in the manifold, immediately after the cylinder head. You must install a resistor sensor type K (max. 1000 ° C) in one or more exhaust ducts.
The sensor should sit as close to the cylinder head as possible to obtain accurate values. The sensors must be connected to a data collector that has relatively fast logging so that all fluctuations are captured. At the same time, it is also important that the sensors are as small as possible, as the larger a sensor is, the longer it will take to react to the temperature changes. If you invest in an injection plant, such as VEMS you will have the opportunity to simultaneously log data while driving.
If the temperature in the exhaust gas is measured, it must be:
Idle time: 332°C
Partial load: 500-600°C
Full throttle: 710-766°C
Under no circumstances may the temperature exceed 900 ° C for a petrol engine and 950 ° C for a diesel engine. If you get above these temperatures, you will get burnt pistons and cracks in the cylinder head.
