How does a fuel heater function in a fuel system?

A fuel heater functions as a heat exchanger to warm the fuel before it enters the engine. This is important because cold fuel can lead to issues such as poor atomization during combustion, increased viscosity, and potential fuel line freezing in low-temperature environments. By utilizing heat from the engine or combustion process, the fuel heater raises the temperature of the fuel, ensuring that it is at an optimal temperature for efficient combustion and system performance.

This process prevents cold fuel from negatively impacting engine performance, helping to maintain efficiency and reliability under various environmental conditions. By effectively increasing the fuel's temperature, the heater promotes better fuel atomization, enhances combustion efficiency, and improves overall engine response.
