Reasons for High Exhast Gas Temperature (EGT) in â

Exhaust gas is by-product of combustion and is naturally at a high temperature. But there is a limit to the diesel engine exhaust gas temperature, and it should not exceed the manufacturer's stated values. Learn what problems can cause this rise in exhaust gas temperature in order to enable troubleshooting and so that taking care of these factors results in restoring normal temperatures.
