And aftermarket exhaust pipe can get even hotter, with temperatures reaching up to 1,000 degrees Fahrenheit. Insulating exhaust components slightly raises temperatures within the exhaust and causes gas particles to flow faster out of the muffler. The counter current design is the most efficient, in that it can transfer the most heat from the heat (transfer) medium per unit mass due to the fact that the average temperature difference along any unit length is higher. 9 5697 spn fault code name is Engine Exhaust Gas Port 12 Difference from Average Temperature. It is influenced by factors such as torque and the design of exhaust piping. If the temperature of the exhaust gas is significantly hotter than that of the radiator, it is typically a sign of a problem such as an improperly functioning radiator, an overloaded engine, or even an exhaust gas recirculation valve that isn’t working correctly and should be inspected by a mechanic. The average gross heating value of natural gas is approximately 1,020 British thermal units per standard cubic foot (Btu/scf), usually varying from 950 to 1,050 Btu/scf. EGT is also a measure of engine health in gas-turbine engines (see below). It may be measured by an exhaust gas temperature gauge. EGT gauges are found in certain cars and aeroplanes.
