What is the best place location for the probe to be positioned?

Exhaust Gas Temperature (EGT) Probe placement in the exhaust path requires special attention. If it is closer than 1½ inches to the cylinder head, probe life will be limited, too far away the probe will be less responsive[read more]

What are thermocouples?

Thermocouples consist of a pair of dissimilar metal wires joined typically at one end, producing a net thermoelectric voltage between the open pair according to the size of the temperature difference between the ends, the relative Seebeck coefficient of the wire pair and the uniformity of the wire-pair relative to the Seebeck coefficient. Thermocouples measure a relative temperature not an absolute temperature. In other words, a thermocouple requires a reference of known temperature. Commonly...[ Read more ]

How many probes do I need for my application?

There are two basic ways EGT probes are installed in multiple cylinder engines either for monitoring a bank cylinders or each individual cylinder. Monitoring a bank of cylinders give you information on the over all exhaust gas temperature generated [read more]

How do I tune my engine using Exhaust Gas Sensors?

rom the peak EGT, either increasing or decreasing the fuel to air ratio causes a decrease in EGT. Richer than peak EGT cooling occurs because there is excess fuel, and leaner than peak, cooling occurs because there is excess air. So you must have a basic idea of where you are starting from regarding base cylinder exhaust gas temperatures and rich or lean condition[read more]

What are some of the benifits to using an Exhaust Gas Thermocouple EGT?

Operation at peak EGT, particularly on long runs like in road racing or circle tracks, will give a fuel savings meaning less pitting for fuel (increased range) as well as less likelihood of spark plug fouling [read more]
