Using the TIT Instrument to Lean Your Engine Using the TIT Instrument to Lean Your Engine Using the TIT Instrument to Lean Your Engine Using the TIT Instrument to Lean Your Engine Using the TIT Instrument to Lean Your Engine You will want to lean your engine in cruise. A rich running engine wastes fuel needlessly and tends to run on the rough side. This create vibration, which causes deterioration of engine accessories and engine mounts. Also, proper leaning at cruise and during descent means less spark plug fouling, longer life for the plugs, reduced maintenance costs and considerable fuel savings. Fur- thermore, good leaning techniques result in cleaner combustion chambers with fewer lead salt deposits on the pistons and exhaust valves. Under certain conditions, these deposits invite preigni- tion and higher maintenance costs. Proper leaning at cruise during cool or cold weather aids in raising engine and oil temperatures to desirable minimums in order to evaporate the water and acids out of the oil. Water and acids attack the insides of an engine, causing rust and corrosion. The TIT is a collection of the EGT's for all the cylinders. As you lean the engine, one cylinder will reach peak EGT before the others. As you continue to lean, the EGT for the leanest cylinder will decrease in temperature but the TIT will continue to increase. When the combined total of all the increasing cylinders equals all the decreasing cylinders, the TIT will reach peak. For this reason, using a TIT to lean an engine is not as desirable as using a multi-channel EGT instrument. But, if you must lean the engine using only the TIT, perform the following steps: A. Rough Leaning: A. Rough Leaning: A. Rough Leaning: A. Rough Leaning: A. Rough Leaning: Adjust the mixture control from the full rich position to a leaner setting that results in a slight drop in engine RPM or to a setting near peak TIT, as dictated by experience. The mixture control should be left at this setting until the TIT stabilizes. It will take about 20 seconds for the temperatures to stabilize within 1°F. This lag is due to the combustion walls and piston domes increasing in temperature, which affect the combustion and exhaust gas temperatures. To correctly lean an engine you must wait for the To correctly lean an engine you must wait for the To correctly lean an engine you must wait for the To correctly lean an engine you must wait for the To correctly lean an engine you must wait for the engine to thermally stabilize engine to thermally stabilize engine to thermally stabilize engine to thermally stabilize engine to thermally stabilize.

Precision Leaning: B. Precision Leaning: Again, start leaning, making only very small adjustments and waiting 3 to 5 seconds between adjustments. As you approach peak, the exhaust gas tempera- ture will rise much slower until it starts to decrease. When this happens you have reached peak TIT. The 1°F resolution of the digital display will be invaluable in helping you precisely detect peak TIT. If your engine runs rough before peak TIT is reached, note the temperature reading on the TIT instrument. When an engine starts to run rough (not when it loses power, but actually runs rough) the leanest cylinder has gone past peak EGT by 30 to 50 degrees F. The leanest cylinder is misfiring causing the engine to run rough. From this point enrichen the mixture to obtain a 50 degrees F lower TIT from the noted temperature. This will set the leanest cylinder slightly on the rich side of peak EGT. The rest of the cylinders will be run- ning richer than the leanest by an amount dictated by the temperature spread for your engine. With this method you can reasonably lean an engine with the TIT instrument.

Finding The Cylinder That Peaks First: For most engines Step B (Precision Leaning) will result in a properly leaned engine. If you find this to be the case with your engine, this step will not be necessary. But if you want to verify that you have leaned to the cylinder that peaked first and your engine is operating properly, perform the following with the cylinder found in step B at peak EGT: Slightly enrich the mixture and quickly step through each cylinder. Any cylinder that shows a rising temperature is a leaner cylinder. Check that this cylinder does not rise more than 15°F before it starts decreasing in temperature. If a cylinder rises more than 15°F it may have a problem. 2. 2. 2. 2. 2. EGT Diagnostics EGT Diagnostics EGT Diagnostics EGT Diagnostics EGT Diagnostics Since the EGT is directly related to the combustion temperature, it is an indication of the engine’s ability to produce power. If the engine is not producing the correct amount of power, the EGT instrument can be a very valuable troubleshooting tool as well an early warning system before engine failure occurs. With 1‘F resolution, our digital EGT instruments will react to the slightest changes in the combustion process. To detect a problem, become familiar with your engine’s normal EGT readings during run-up, climb, cruise and descent. Any difference from the norm can be a sign of trouble. During normal operation the EGT will stabilize to 1°F for a given throttle and mixture setting. If it does not stabilize, this can also be the first sign of trouble. With rate and trend information 6 Operating Information Operating Information Operating Information Operating Information Operating Information 7 CHTs CHTs CHTs CHTs CHTs being displayed instantaneously and with temperatures being read to 1°F, few problems can escape the pilot flying one of Electronics International’s analyzer systems. It is not necessary to continually monitor the EGT’s in order to detect a problem. Most problems worsen over a period of time and can be easily detected before they become a safety hazard by thoroughly checking the EGT readings at run-up and once or twice during a flight. The following is a list of EGT/CHT symptoms and possible problems: Symptom Symptom Symptom Symptom Symptom Possible Problem Possible Problem Possible Problem Possible Problem Possible Problem One EGT reads abnormally high. The corre- sponding CHT reads lower than normal. Burned valve or broken ring, defective plug, plug wire or mag. One EGT reads abnormally high. The corre- sponding CHT reads higher than normal. Plugged injector, intake leak. One EGT reads abnormally low. Over-sized injector, restricted exhaust, broken or leaky exhaust header. High CHT’s and/or high EGT’s on all cylin- ders. Excessive leaning with power settings over 75%. Detonation due to bad fuel. Closed or restricted cowl flaps. Missing or loose baffling. Timing problem or defective mag. Jumpy readings on one channel.

CHT Operation CHT Operation CHT Operation CHT Operation CHT Operation The Cylinder Head Temperature (CHT) instrument helps the pilot protect his engine against the threat of excessive heat. Most general aviation aircraft monitor the hottest CHT as determined by extensive flight tests done by the airframe manufacture. Minimum in-flight CHT should be 150°F, and maximum in most direct drive normally aspirated Avco Lycoming engines is 500°F. Some of the higher powered, more complex engines have a limit of 475°F. Although these are minimum and maximum limits, the pilot should operate the engine at more reasonable temperatures in order to achieve the expected overhaul life of the powerplant. It would be normal during all-year opera- tions in climb and cruise to see cylinder head temperatures in the range of 350°F to 435°F. Sudden cooling of the CHT (known as shock cooling) is a problem that is common with aircraft engines. This is caused by fast descents with little or no power and rich mixtures. This may result in bent pushrods due to exhaust valves sticking, burnt valves, spark plug fouling, broken piston rings, cracked cylinders at the spark plug and valve ports and warped exhaust valves. To avoid these problems, do not allow the CHT to cool more rapidly than 1°F every 3 seconds during in- flight operation. This can be easily detected with our 1°F digital display. During climbs, the cylinder head temperatures will rise rapidly until the heat absorbed by the combustion walls is dissipated out the engine’s cooling fins. At this point, the CHT will stabilize. Any change in throttle, mixture, cowl or airspeed will affect the CHT and the rate at which it will change. Since rate and trend information can be easily interpreted from our digital display, changing any one of these parameters to stabilize, slow or reduce the CHT is possible with almost immediate results. Our digital instrument takes the guesswork out of controlling your CHT. 9 4. 4. 4. 4. 4. CHT Diagnostics CHT Diagnostics CHT Diagnostics CHT Diagnostics CHT Diagnostics The source of heat in an engine is from the combustion of the fuel/air mixture producing tempera- tures of approximately 4000°F. Some of this heat energy goes into heating the cylinder heads through radiation and conduction. This heat is sinked away from the engine by the air flow over the cylinder heads. When the heat being generated in the cylinder heads equalizes with the heat being sinked away, the cylinder head temperature will stabilize. If a problem arises in the com- bustion chamber or in the ability of the cooling system to sink away heat, the CHTs will be af- fected. To detect a problem, become familiar with your engine’s CHT operating temperatures during run-up, climb, cruise and descent. Any differences from normal can be a sign of trouble. Continuous change in the CHT can also be a sign of trouble. Because of the large thermal mass of the engine, the CHT’s change slowly after the initial climb. Any continuous change in one or all of the CHTs after this initial climb can be the sign of trouble. The rate and trend of this change can easily be detected with Electronics International’s 1°F resolution digital display. This information allows the pilot to make changes in flight attitude or engine operation and see the effects almost instantaneously.

CHT Probe Installation CHT Probe Installation CHT Probe Installation CHT Probe Installation CHT Probe Installation Most engines have a port just below the lower spark plug for the CHT probe. Replace your existing Primary CHT probe with one of Electronics International’s CHT probes. It is important to install the same type of CHT probe as was removed from the engine. A bayonet and screw-in type probe may be interchanged. Your current CHT probe was installed in the hottest cylinder determined by extensive flight testing. If you suspect your current probe was not installed on the correct cylinder or the probe type is incorrect, contact your airframe service department for this information. 3. 3. 3. 3. 3. TIT Probe Installation TIT Probe Installation TIT Probe Installation TIT Probe Installation TIT Probe Installation Electronics International offers a variety of TIT probes. The following describes the steps for installing each of these probes. A. Hose Clamp EGT/TIT Probe - A. Hose Clamp EGT/TIT Probe - A. Hose Clamp EGT/TIT Probe - A. Hose Clamp EGT/TIT Probe - A. Hose Clamp EGT/TIT Probe - Remove the existing TIT probe and drill this hole out using a 13/64 inch drill bit. This will insure easy installation and removability of the probe. Insert the EGT probe and tighten the hose clamp. As the hose clamp is heated and cooled it will become loose as it conforms to the exhaust stack. After the first 10 hours of operation, retighten this clamp. B. Screw-in TIT Probe - B. Screw-in TIT Probe - B. Screw-in TIT Probe - B. Screw-in TIT Probe - B. Screw-in TIT Probe - This probe has an adjustable depth so it can be adjusted for any application, but it can only be adjusted once. Once the ferrule has been compressed, the probe depth cannot be changed. Perform the following steps: 1. 1. 1. 1. 1. Remove your current TIT probe and check that your E.I. probe and compression fitting will fit and work properly. E.I. offers three screw-in TIT probes (1/8" NPT, 1/4" NPT and 7/16" - 20). 2. 2. 2. 2. 2. Determine the correct depth the probe sheath should extend beyond the compression fitting. Do this by checking it against your current TIT probe (1" is standard). 3. 3. 3. 3. 3. Set the compression fitting by tightening the cap into the body using a wrench. 4. Install your E.I. TIT probe into the exhaust stack and tighten. 4. 4. 4. 4. 4. EGT Probe Installation EGT Probe Installation EGT Probe Installation EGT Probe Installation EGT Probe Installation Look at each exhaust stack and determine the best location at which all of the EGT probes can be mounted at the same distance down from the exhaust ports. The ideal location is 1 1/2", but ease of installation should prevail. Drill a 13/64" diameter hole in each exhaust stack. Insert the probe and tighten the hose clamp. As the hose clamp is heated and cooled, it will become loose as it conforms to the exhaust stack. After the first 10 hours of operation, each hose clamp should be retightened. 11 Installation Instructions Installation Instructions Installation Instructions Installation Instructions Installation Instructions 12 Route the Extension Cables Route the Extension Cables Route the Extension Cables Route the Extension Cables Route the Extension Cables IMPORTANT NOTE: For Cessna 210’s or any aircraft using a slip joint in the exhaust system, install the EGT probes ABOVE OR BELOW THE SLIP JOINT.

Be sure the connectors mate properly. Be sure the connectors mate properly. When tie wrap- ping these cables down, be sure there is no strain or pulling on the cable against the probe housing. Each probe should have 3 to 4 inches of slack to allow the engine to move in its mount without breaking any wires. Also, there should be a tie wrap near the probe connectors. Dress each cable up to the instrument or remote switch keeping them away from any hot areas (exhaust stacks, cylinder heads, etc.). We do not recommend removing the connectors when installing the extension cables but if you must shorten the cable, pull any excess cable length through the fire wall and cut it off at this time. However, it is recommended you leave some extra wire length under the instrument panel for later modifications. Varying cable lengths will not not not not not affect the accuracy of this instrument so cables of any length may be ordered from the factory. The Extension Cables and probe wires are made of type K thermocouple wire that must not be substituted or extended with regular copper wire. Also, it is important these wires not be kinked (i.e., do not bend the wires on a radius less do not bend the wires on a radius less do not bend the wires on a radius less do not bend the wires on a radius less do not bend the wires on a radius less than 1 inch than 1 inch than 1 inch than 1 inch than 1 inch). ).). ).). Connect the Extension Cables using the OLC-1 connectors as described below: A. Strip back the insulation on the two mating wires 3/8". Be careful not to nick the wires. B. Place the hex driver (0.050") in the OLC-1 set screw and back out the set screw to the last thread. C. Inset the two wires into the ends of the connector so the wire insulation is just inside the nylon housing and the ends of the wires are not exposed on the opposite side. D. Tighten the set screw until the set screw stops turning and the hex driver starts to flex (4 to 5 in.-lbs.) E. Tug on the wires (1 to 2 lbs.) to insure proper connection. Tie off any excess cable under the instrument panel. Be sure these cables do not obstruct the freedom of travel of any controls.

We have few problems with our probes, cables and units and installation is simple. Usually fixing a problem is just a matter of inspecting the installation at a few key points. Strategy Strategy Strategy Strategy Strategy If you have more than one problem, FIX ONE PROBLEM AT A TIME FIX ONE PROBLEM AT A TIME FIX ONE PROBLEM AT A TIME FIX ONE PROBLEM AT A TIME FIX ONE PROBLEM AT A TIME..... Trying to fix all of them at once can be confusing and misleading. In many cases fixing one problem first will lead you to the solution for fixing all of the problems. Therefore, take one problem on one channel and proceed with the following: 1. 1. 1. 1. 1. Instrument Check Out Instrument Check Out Instrument Check Out Instrument Check Out Instrument Check Out If there is an identical symptom on each channel, then the instrument may have a problem. But if even one channel of the instrument is operating properly, the instrument probably does not have a problem. A good method to test the instrument is to remove all the Extension Cables. Then look for a reading on all channels to be near cabin temperature. The only inputs a unit requires to operate properly and measure cabin temperature is power (red lead) and ground (black lead). Check the power and ground leads for proper connection (pull on the wire at each connector). NOTE: Few problems turn out to be the instrument. 2. 2. 2. 2. 2. Probe Check Out Probe Check Out Probe Check Out Probe Check Out Probe Check Out There are two good methods of testing a probe. Perform one or both of the following: A. A. A. A. A. A probe can be tested with an ohmmeter. Disconnect the probe from the Extension Cable. When testing the resistance between the connectors, the probe should measure a “short” (less than 5 ohms). When measuring from one lead (either lead) of the probe to the probe sheath (metal tip), there should be an “open” (10k or greater). 15 Extension Cable Check Out Extension Cable Check Out Extension Cable Check Out Extension Cable Check Out Extension Cable Check Out Troubleshooting Suggestions Troubleshooting Suggestions Troubleshooting Suggestions Troubleshooting Suggestions Troubleshooting Suggestions B. B. B. B. B. Another method of checking a probe is to plug the suspected bad probe into a channel that is working properly. If the problem follows the probe, you have a defective probe. 3. 3. 3. 3. 3. Extension Cable Check Out Extension Cable Check Out Extension Cable Check Out Extension Cable Check Out Extension Cable Check Out With the Extension Cable connected to the unit, remove the probe from the suspected bad Exten- sion Cable. Set the unit to the proper channel and look for a near cabin temperature reading on the display. A very high or low reading indicates a short to ground in the cable. Next, connect an ohmmeter, set to 10K range, to the open probe ends of the suspected bad Extension Cable. Set the unit to the proper channel and look for a very high (+ or -) reading on the digital display. A near cabin temperature reading or no change in reading indicates an open in the cable or its connec- tors. Also, look for a reading on the ohmmeter around 12K ohms.
