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... [ 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]

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]
