Temperature Sensor 4307480 in Cummins Engines

The Temperature Sensor 4307480, manufactured by Cummins, is a component in the ISL G CM2180 and ISX12 G CM2180 EJ engines. This sensor plays a role in monitoring the engine’s temperature, ensuring optimal performance and preventing potential overheating issues.

In the ISL G CM2180 engine, the temperature sensor is strategically positioned to provide real-time data to the engine control unit (ECU). This data is essential for maintaining the engine’s efficiency and longevity. Similarly, in the ISX12 G CM2180 EJ engine, the sensor’s placement is designed to capture accurate temperature readings, which are vital for the ECU to make necessary adjustments to the engine’s operation.

Both engines rely on the precise functionality of the temperature sensor to manage various parameters, including fuel injection timing and cooling system operations. The sensor’s role in these engines underscores its importance in the overall engine management system ⁹.

Role of Part 4307480 Temperature Sensor in Engine Systems

The part 4307480 temperature sensor is a component in the effective operation of several engine systems. Its primary function is to monitor and relay temperature data to the Engine Control Module (ECM). This data is vital for the ECM to make informed decisions regarding fuel injection timing, ignition timing, and other parameters that ensure optimal engine performance.

Interaction with the Engine Control Module (ECM)

The temperature sensor continuously sends temperature readings to the ECM. The ECM uses this data to adjust various engine parameters. For instance, during cold starts, the ECM may enrich the fuel mixture based on the temperature sensor’s input to ensure smooth engine operation. As the engine warms up, the ECM will lean out the mixture for better fuel efficiency, all guided by the temperature sensor’s accurate readings ¹⁰.

Turbocharger Management

In turbocharged engines, the temperature sensor plays a role in managing the turbocharger’s operation. The ECM uses temperature data to control the wastegate, which regulates the turbocharger’s boost pressure. Higher temperatures can indicate increased engine load or potential overheating, prompting the ECM to adjust the wastegate to maintain safe operating conditions. This ensures that the turbocharger operates within its optimal range, enhancing both performance and durability ¹¹.

By providing real-time temperature data, the part 4307480 temperature sensor enables the ECM to make precise adjustments, resulting in improved engine efficiency, reduced emissions, and enhanced overall performance.

Conclusion

The Cummins 4307480 Temperature Sensor is a vital component in the operation of commercial truck engines.
