SE75 Excavator Water Temperature Sensor J170-92B-050000

SE75 Excavator Coolant Temperature Sensor J170-92B-050000

The "SE75 Excavator Coolant Temperature Sensor J170-92B-050000" is a temperature sensor specifically designed for the SE75 excavator model, with part number J170-92B-050000. Its main function is to monitor the engine coolant temperature and transmit the temperature signal to the ECU (Electronic Control Unit) to optimize engine management functions such as fuel injection, ignition timing, and idle speed control.

Main Functions

The coolant temperature sensor monitors the coolant temperature in real time through a built-in thermistor and converts the physical temperature change into an electrical signal, which is then transmitted to the ECU.

Temperature Signal Acquisition and Feedback: Real-time monitoring of coolant temperature provides data support to the ECU.

Fuel Injection Optimization: Increases fuel injection during cold starts and reduces fuel injection after normal operating conditions to balance fuel consumption and power.

Ignition Timing Correction: Increases the ignition advance angle at low temperatures and retardes the ignition angle at high temperatures to protect the engine.

Idle speed stability control: Increase idle speed at low temperatures to ensure smooth operation during cold starts.
