Product Application : Screw-in Vent


Engine Controller Unit (ECU), the core component of an electronically controlled vehicle, constantly monitors and controls the normal operations of the engine. ECU tests and calculates the air-fuel mixture ratio and engine ignition advance angle based on the data input from multiple sensors, including MAP sensor, throttle position sensor, air temperature sensor, and oxygen sensor, etc. It monitors and controls the engine’s fuel supply, fuel injection timing, ignition closing angle, engine idling operation and other vehicle accessory systems in real time to maintain the best energy conversion rate.   ECU has complex structures and is exposed to rugged environments during operation, so it needs special protection. For example, due to frequent temperature changes in the working area caused by the heat dissipation of the controller’s electronic components, it is necessary to use venting products, which not only dissipate heat, but also equalize pressure. Specific requirements for venting products are as follows:  

  1. Large air permeability;
  2. High IP rating;
  3. Long-term heat resistance;
  4. Resistance to salt fog corrosion.

  IPRO screw-in vent has large air permeability, good sealing performance, high IP rating, long heat resistance time, and salt fog and chemical corrosion resistance. IPRO screw-in vent is made with high WEP and precision welding technology to realize an IP rating of IP67, IP68 and IP69K; The casing materials is composed of Nylon and ePTFE, which is validated by multiple OEMs and mainstream standards and can provide reliable protection for ECU.

Key Features
  • 100% full inspection of WEP;
  • Meet automotive grade.
  • Total heat resistance solutions;
