The role of a heater on the fuel supply line in a combustion engine primarily revolves around preventing liquid formation, especially in the context of fuels such as diesel. When the fuel temperature is too low, it may not remain in a completely fluid state, leading to the potential for wax or other constituents to solidify. This can cause clogging or a lack of flow, which would adversely affect engine performance.

By using a heater, the fuel is kept at a sufficiently high temperature to ensure it remains in the appropriate state for efficient combustion. This is crucial because a solidified fuel can lead to operational problems, particularly in colder climates where temperatures drop significantly. Overall, maintaining a liquid state ensures that the fuel can be properly filtered and delivered to the combustion chamber without interruption, promoting smoother engine operation and reliability.
