There is a big difference between ‘Ambiënt’ temperature and ‘effective’ temperature.
Having a temperature monitoring sticker on the backplate indicating 105°C / 221 °F for
example means that the engine has temperatures of over 130 – 140°C/266°F – 284°F
These temperatures are having a distructive influence on your engine !
EGT and CHT ?
An exhaust gas temperature gauge (EGT gauge) is a meter used to monitor the exhaust gas
temperature of an internal combustion engine in conjunction with a thermocouple-type
pyrometer. ... By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel
ratio (AFR).
Cylinder Head Temperature (CHT) Gauge - Indicates the temperature of at least one of the
cylinder heads. Used to set the fuel/air mixture.
D-Motor delivers optional a dashboard gauge with monitoring probes per cylinder. (P/N
