How to Solve Excessive Exhaust Temperature?

[DiDaniela]

Excessive exhaust temperature can be resolved through the following methods: 1. Insufficient coolant: The engine cooling system may lack antifreeze due to potential leakage points such as water pump leaks, damaged pipes, or a broken radiator. 2. Excessively high concentration of combustible mixture in the cylinder: In such cases, it is necessary to inspect whether the oxygen sensor and fuel injection system have any faults. If the oxygen sensor fails, the vehicle will not be able to automatically control the fuel injection volume. 3. Abnormal cylinder pressure and ignition timing: A decoder can be used to read the data stream from the knock sensor, and then adjustments can be made to the fuel injection volume and ignition timing based on the data stream information.
