product description

introduce

"Pressure temperature dual sensor M11 ISC ISL ISM ISX ISB 2872784 2897334 for Cummins parts" refers to the dual pressure and temperature sensor of Cummins engines, which is suitable for various models of engines such as M11, ISC, ISL, ISM, ISX, ISB, etc., and the product numbers are 2872784 and 2897334. The following is a detailed introduction:

### Function
- This sensor integrates the functions of pressure sensor and temperature sensor. The pressure sensor is used to measure the absolute pressure in the engine intake manifold, and the temperature sensor is used to monitor the temperature of the intake air. The information of intake pressure can help the engine control unit (ECU) accurately calculate the intake volume, so as to accurately control the fuel injection volume according to the working conditions of the engine; the intake temperature information is used to correct parameters such as fuel injection and ignition timing to ensure that the engine can maintain the best performance, fuel economy and emission levels under different ambient temperatures and working conditions.

### Applicable engine models
- **M11**: It is a classic engine model of Cummins, commonly used in heavy trucks, large buses and some industrial equipment. It has a wide power coverage range and can meet the power requirements of different application scenarios.
- **ISC**: It is generally used in medium-sized trucks, buses and other fields. It has good power output and fuel economy, and performs well in urban logistics and passenger transportation.
- **ISL**: It is often used in school buses, city buses and some light trucks, etc. It focuses on low emissions and comfort, and can provide passengers with a quieter and more comfortable riding environment.
- **ISM**: It is mainly aimed at heavy-duty trucks, tractors, etc. It has the characteristics of high torque and high reliability, and is suitable for long-distance transportation and heavy-load conditions.
- **ISX**: It is a high-end heavy-duty engine series of Cummins, widely used in long-distance transportation, construction engineering and other fields, and is famous for its powerful power, excellent reliability and low operating costs.
- **ISB**: It is a relatively compact and efficient engine suitable for a variety of models such as light trucks, vans, pickups, etc. It not only meets the power requirements, but also has good fuel economy and environmental performance.

### Working principle
- The pressure measurement part usually uses piezoresistive or capacitive sensor technology. When the pressure in the intake manifold changes, the resistance or capacitance value inside the sensor will change accordingly, and this change will be converted into an electrical signal and output to the ECU through the circuit. The temperature measurement part generally uses components such as thermistors or thermocouples, whose resistance values ​​will change with the changes in the intake temperature. The ECU calculates the intake temperature based on the voltage or resistance signal output by the sensor.

### Fault impact
- If the sensor fails, it may cause the engine control unit to receive incorrect pressure or temperature signals, which will cause deviations in the engine's fuel injection, ignition timing and other controls. This may cause problems such as difficulty in starting the engine, power loss, poor acceleration, increased fuel consumption, and excessive exhaust emissions. In severe cases, it may even cause the engine to fail to operate normally.

### Maintenance and Care
- Regularly check whether the sensor connection line is loose or damaged, and ensure that the connection between the sensor and the intake manifold is well sealed to prevent leakage from affecting the measurement accuracy. Avoid external impact or severe vibration of the sensor to avoid damage to internal components. When maintaining the engine, professional testing equipment can be used to calibrate and test the sensor, and faulty sensors can be found and replaced in time to ensure the normal operation of the engine.
