4. System Functionality
El Webasto Air Top EVO 40 operates as a forced-air diesel heater. It draws in fresh air, heats it using a combustion process, and then circulates the warm air into the vehicle's interior. The system includes a glow plug for ignition, a fuel pump for precise fuel delivery, and a control unit to manage the heating process.
Figura 4.1: Secció transversal view of the air heating system, illustrating key internal components such as the glow plug, combustion chamber, heat exchanger, impellers, control unit, and various sensors.
Key functional components include:
- Heater Housing: Encloses all internal components.
- Combustion Air Blower: Supplies air for the combustion process.
- Tubular Combustion Chamber: Where fuel is ignited and burned.
- Termocambiador: Transfers heat from the combustion gases to the circulating air without mixing.
- Hot Air Blower: Circulates the heated air into the vehicle.
- Unitat de control: Manages all heater functions, including ignition, fuel delivery, and temperature regulation.
- Bomba de combustible: Delivers precise amounts of diesel fuel to the combustion chamber.
- Bugia incandescent: Ignites the fuel-air mixture during startup.
