Customized Electronic Exhaust Acoustic Valves Casting Parts for Car exhaust system
Our Electronic Exhaust Acoustic Valves Casting technology helps reduce CO2 emissions, enhance acoustics and improve vehicle performance.The electronic acoustic valve incorporates a dynamic flap control designed to generate optimal pressure conditions for efficient EGR and also provides fail-safe operation that automatically returns the flap to the open position should a failure occur, such as in the case of a signal interruption.
The valves feature a modular design, which offers vehicle manufacturers custom flexibility and adaptability for any engine architecture.
The Electronic Exhaust Acoustic Valves offer a range of uses, including managing engine sound; recirculating a portion of a vehicle’s exhaust gases back into the cylinders to lower NOx emissions; as a bypass valve in energy recovery and tuning the exhaust system’s acoustics to support cylinder deactivation modes in light-load driving for fuel efficiency gains. The valves can help reduce CO2 emissions by providing vehicle manufacturers the ability to reduce muffler weight and volume while maintaining precise control over engine sound and ambient temperatures.
