On some test benches, individual components need to be preconditioned (temperature controlled). For example, an automotive fuel injector is a solenoid valve design. When the solenoid coil is energized, it generates suction, lifting the needle valve to open the nozzle hole. Fuel is sprayed at high speed through the annular gap between the needle valve head and the nozzle hole, forming a fine mist that promotes complete combustion. Therefore, the quality of fuel injection directly affects whether the engine can operate normally. To simulate cold starts of different vehicles, fuel (such as diesel or gasoline) is injected into the engine at a preset temperature. In this experiment, the injector is temperature-controlled by the JULABO Presto.
