1. Definition
Parking heaters (also called diesel/gasoline heaters) are vehicle-mounted devices that heat interior air and the engine without starting the main engine.
2. Primary Purpose
Preheat air and engine in cold conditions to enable quick, safe vehicle startup and improve passenger comfort.
3. Working Principle
Fuel Supply: Diesel or gasoline is delivered to the heater via a fuel pump.
Combustion: Fuel mixes with air and ignites in the combustion chamber, generating high temperatures.
Heat Transfer: Heat is transferred to interior air (via a heat exchanger) or to the engine (via the cooling system).
Exhaust: Combustion gases are expelled outside through the exhaust pipe, keeping interior air clean and safe.
Parking Heater Core Functions
Engine Preheating: Warms the engine pre-startup for smoother startup, less cold-start wear/stress, and longer engine life.
Better Fuel Efficiency: Cuts cold-start fuel use to save fuel and lower operational costs.
Interior Heating: Rapidly warms the cabin, providing comfort for drivers/passengers without waiting for the vehicle to heat up.
Defrosting & Demisting: Clears windshields/windows pre-startup, boosting winter driving safety with a clear view.
Remote & Timer Control: Comes with remote control and timer functions—start the heater remotely or preset heating time to ensure a comfortable cabin temperature when entering.
