How to Fix a Red-Hot Exhaust Pipe?

[ElleLynn]

To address a red-hot exhaust pipe, it's necessary to identify the underlying cause and apply the appropriate solution. Below are specific explanations regarding a red-hot exhaust pipe: 1. Lean Air-Fuel Mixture: An excessively lean mixture results in slow combustion during the power stroke, causing combustion to continue into the exhaust stroke. The burning gases entering the exhaust pipe can cause it to turn red-hot. 2. Delayed Ignition Timing: Late ignition leads to the combustible mixture still burning when the exhaust valve is open. The burning gases rushing into the exhaust pipe through the exhaust valve continue to combust inside the pipe, heating it until it glows red. 3. Exhaust Valve Not Sealing Properly: If the exhaust valve doesn't close tightly, burning gases from the power stroke can leak through the improperly sealed valve into the exhaust pipe, heating it to a red-hot state. In severe cases, this can damage the valve.
