When rpm goes up engine start to smoke?

When the RPM (revolutions per minute) of an engine increases and it starts to smoke, it often indicates a problem with the engine's lubrication or combustion process. Excessive RPM can lead to overheating, causing oil to break down and produce smoke. Additionally, if the engine is burning oil due to worn piston rings or valve seals, higher RPMs can exacerbate this issue, resulting in visible smoke. It's crucial to address the underlying cause quickly to prevent engine damage.
