DONGFENG TRUCK FOTON TRUCK Cummins ISZ 15N ENGINE Humidity Sensor C4384340
FUNCTION
1. Real-time Air Humidity Monitoring: Precisely measures the relative humidity of the engine intake or surrounding environment, and transmits this data as electrical signals to the Engine Control Unit (ECU).
2. Combustion Control Optimization: The ECU utilizes humidity data to adjust parameters-such as fuel injection volume, ignition timing, and EGR rate-thereby achieving more efficient combustion and enhancing both engine power and fuel (or gas) economy.
3. Emissions Control Support: Assists in meeting National VI emission standards by optimizing the operating conditions of the after-treatment system, thereby reducing the emission of pollutants such as nitrogen oxides (NOx).
4. Engine and After-treatment System Protection: By monitoring for excessive humidity, it prevents issues caused by high moisture levels-such as combustion instability, sensor drift, or crystallization within the after-treatment system-thereby enhancing the overall reliability of the system.
Installation Location
Installed in the engine intake tract (within the intake manifold or the mid-section of the intake pipe), or in associated lines of the aftertreatment system, it is positioned to directly contact the intake airflow in order to accurately measure ambient or intake humidity.
Working Principle
The sensor applies an AC voltage to the sensing element to detect changes in capacitance.
It also incorporates an integrated temperature sensor to measure the ambient temperature.
It converts changes in humidity and temperature into standard electrical signals, which are then transmitted to the Engine Control Unit (ECU) via a connector.
Advantages
| Functional Feature / Advantage | Detailed Description | Practical Benefits |
|---|---|---|
| High-Precision Humidity Monitoring | Real-time and accurate measurement of intake air or ambient relative humidity, with fast signal transmission to the ECU | Provides precise intake condition data for better combustion control |
| Combustion Optimization Support | Helps the ECU adjust gas injection quantity, ignition timing, and EGR rate for more efficient combustion | Improves engine power output and fuel (gas) economy |
| Emission Control Support | Optimizes the aftertreatment system (SCR) operating conditions to help meet strict National VI emission standards | Reduces NOx and other pollutant emissions, ensuring compliance with environmental regulations |
| Temperature & Humidity Combined Detection | Some versions simultaneously monitor ambient temperature for integrated temperature-humidity sensing | Delivers more comprehensive intake parameters, improving ECU control strategy accuracy |
| Strong Durability | Uses high-quality original factory materials, resistant to high temperature, vibration, and corrosion | Suitable for harsh heavy-duty truck conditions, with long service life and low failure rate |
| Compact Structure | Small and compact design, plug-and-play installation directly on the intake pipe | Easy to install and saves space in the engine compartment |
| System Protection Function | Sends timely signals when humidity is too high to prevent unstable combustion or aftertreatment system crystallization | Protects the engine and aftertreatment system, reducing the risk of failures |
| Seamless Integration | Perfectly matched with Cummins ECU and supports intelligent diagnostic functions | Enhances vehicle intelligence and makes fault diagnosis and maintenance easier |
