4. Функциональность системы
The 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.

Рисунок 4.1: Поперечное сечение 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: Подает воздух для процесса горения.
- Tubular Combustion Chamber: Where fuel is ignited and burned.
- Теплообменник: Transfers heat from the combustion gases to the circulating air without mixing.
- Hot Air Blower: Circulates the heated air into the vehicle.
- Блок управления: Manages all heater functions, including ignition, fuel delivery, and temperature regulation.
- Топливный насос: Delivers precise amounts of diesel fuel to the combustion chamber.
- Свеча накаливания: Ignites the fuel-air mixture during startup.
