Weicai
Product Overview
Maintain peak engine performance and Euro VI/Stage IV emissions compliance with our premium Relative Humidity and Intake Air Temperature Sensor. Specifically engineered for Weichai Power engines, this sensor (OE #1001801878) provides high-accuracy data to the Engine Control Unit (ECU).
By precisely measuring atmospheric humidity and ambient temperature, it allows for real-time adjustments to the EGR (Exhaust Gas Recirculation) system and fuel injection timing. This prevents engine “knocking,” reduces NOx emissions, and optimizes fuel consumption in heavy-duty environments.
Technical Features
-
Dual-Function Sensing: Measures both relative humidity and intake air temperature in a single compact unit.
-
OEM Grade Reliability: Built with high-stability polymer capacitive technology for fast response times.
-
Extreme Durability: IP6K9K rated housing to resist high-pressure washing, dust, and heavy engine vibration.
-
Gold-Plated Terminals: Ensures superior electrical conductivity and prevents corrosion in humid environments.
Vehicle & Engine Applications
This sensor is a critical component for Weichai heavy-duty engine series used in trucks, construction machinery, and power generation:
-
Engine Series: Weichai WP10, WP12, and WP13 (Euro V / Euro VI models).
-
Vehicle Brands: Widely used in Shacman (Shaanxi), FOTON Auman, and Beiben heavy-duty trucks.
-
Industrial Use: Compatible with various Weichai-powered wheel loaders and excavators.
