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. them and could guess when maintenance is due, but then. Why not have an exhaust temperature gauge (EGT), as do general aviation (GA) aircraft? Thats why its so important to manage the powerplant in a fashion that limits CHTs to a tolerable value. The advantage of an EGT is that it detects changes in A Cylinder Head Temperature Gauge (CHT) measures the temperature of an engine's cylinder heads.

A reamer works much better than a drill bit. EGT is affected by mixture. Always use a torque wrench to tighten the spark plug to specifications. By monitoring EGT, the driver or pilot can get an idea of the vehicle's air-fuel ratio (AFR). Abercrave Click to download the VDO installation guide in .pdf format. It's the only one in this price range that provides accurate digital readouts (in fact it's the only accurate gauge in this price range, including traditional analog models like VDO). Richer mixtures also cause EGT to decrease because excess (unoxidized) fuel absorbs heat energy when it vaporizes. I use a infrared thermometer pointed near the spark plug, not at the spark plug. has to be monitored closely or the pilot may burn up his engine. mechanical problems with the engine. Recently installed some CHT gauges on some fan cooled sleds. Bottom line: a cool running engine will last longer and have fewer problems. Aviasport. CHT mainly reflects whats going on in the cylinder during the Otto cycle power stroke before the exhaust valve opens, while EGT mainly reflects whats going on during the exhaust stroke after the exhaust valve opens: High CHTs generally indicate that the engine is under excessive stress for its own good.

Please do NOT rely on PHOTOS while shopping as many of our products have selectable product options that may change the nature of the product being ordered compared to the representative photo. Get used to glancing at the CHT often. (If burned valve fails completely, EGT of affected cylinder will go cold and engine will run rough. When adjusting power settings and mixture, CHT is the most important reference measurement, because CHT is the best proxy we have in the cockpit for internal cylinder pressure (ICP) which represents stress on the engine. point. I think the worst we had was one engine that would start detonating at a constant load condition once the plug reached 240 degC. The complaint goes on to state that since 1999, Twin Cam engines between 88 and 110 cubic inches are capable of producing excess heat - enough in fact to cause clothing to catch fire in normal operating conditions. The TIT limit is usually either 1650F or 1750F, depending on the model of turbocharger in-stalled. CHT (cylinder head temperature) gauge w/probe, 2", new, $90 EGT (exhaust gas temperature) . Drill & tap a safe spot on the cylinder head, or carefully epoxy the sensor to the head, making sure you have good contact between the sensor and the cylinder.
