Engine monitoring instrument for aircraft for reading and adjusting the fuel-air mixture in aircraft engines

摘要

The adjustment of the fuel-air mixture required in airplanes with gasoline engines, due to changed air density at different flight altitudes, is very unsatisfactory in the conventional way, since only indirect information is the basis for adjustment procedures and can lead to errors. It would be better to have a direct display that gives precise information about the respective mixing ratio. DOLLAR A With the help of a measurement of the oxygen content in the exhaust gas by means of a lambda probe built into the exhaust gas flow and a display instrument with different color ranges (green, yellow, red) and corresponding lambda value information, which is matched to the outgoing signal voltage of the probe, the respective fuel-air ratio can be read off and adjusted accordingly . DOLLAR A This can be applied to all single or multi-engine aircraft with piston engine and mixture adjustment lever / mixture. It is also particularly suitable for retrofitting.
