As the engine works at high speed or uphill, head temperature will increase quickly. petrol does things like that even at 0! These will be the subject of another article. Consider confirming by doing an in-flight mag check, but be careful if you turn off a mag and the engine quits, pull the mixture control before turning the mag back on to avoid possible afterfire-damage to the exhaust system. must have the sensor at the 8 Join Date: Jan 2011. You are using an out of date browser. if it was 100 F outside, your VDO gauge would read 30 F low, you would need to add 30 F to the gauge readout to determine your true CHT; if the ambient temps are colder than 70 F, then the gauge reads high, and you need to subtract the difference from the gauge readout. These engines were highly stressed and it did not take much of a change to melt a piston or worse. This is especially an issue when using AVGAS. You obviously need an engine monitor to measure the CHT of all six cylinders (or twelve if you fly a twin). Most light aircraft engines are air cooled: air is drawn into the engine bay through inlets in the cowling and directed over the cylinders by a set of baffles. Ambient air about 70-75 deg.F Front to rear variation is only about 5 deg. Aircraft engines can provide thousands of hours of reliable service, provided that they are maintained and operated properly. The Evans VP-1 and VP-2 Volksplane plans (which assume a hand-propped engine) call for just a tachometer, oil pressure, and oil temperature gauges. 650 air-cooled, dual carb, dual ignition, rebuilt (like new! Always do a thorough test of the fuel delivery system before assuming there are ignition or However, its not essential to use EGT for leaning unless youre particularly curious about what air-fuel ratio you are using.
