Prevent damage to your engine and ensure maximum performance and reliability with this AutoMeter Electronic Cylinder Head Temperature Gauge. Richer mixtures also cause EGT to decrease because excess (unoxidized) fuel absorbs heat energy when it vaporizes. It is better too big than too small. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR). As things heat up even more, the piston will seize and the engine will stop. See, hello all, i'm still working on megasquirting a 1965 vespa. as you can imagine lal the sensors are add-ons and i'm very much starting from scratch.

The one-third that actually makes it to the propeller is reflected on another cockpit instrument: the airspeed indicator. Busses tend to run much hotter temps due to the load they are pushing. Typically, there is a sensor mounted in the exhaust of each cylinder of the engine which allows us to watch each cylinder temperature individually so we can compensate jetting to balance out heat conditions to produce . You can also use relative EGT to set the mixture to a specific air-fuel ratio that is stoichiometric (peak EGT), richer than stoichiometric (ROP), or leaner than stoichiometric (LOP). As the 3.0 litre SC engine we have is proving troublesome and needs a rebuild it seems like a good idea to try to convert the CIS to an EFI and I have been looking at various options.
