The parking heater fuel pump is the core power component of the entire parking heating system, compatible with various fuel-powered parking heater devices. It delivers fuel from the storage tank to the combustion chamber with precision and stability, providing reliable fuel supply support. Designed with a pulse-type quantitative fuel delivery system, it dynamically adjusts the fuel supply frequency based on ambient temperature and heater power requirements, maintaining stable fuel delivery even in extreme cold of -40°C. This effectively resolves industry pain points such as diesel solidification and fuel supply interruptions in low-temperature environments. Widely used in heavy-duty trucks, RVs, construction machinery, and cold chain transport vehicles, it enables pre-warming, defrosting, and temperature maintenance functions without the need to start the engine.
