A Study on NVH Performance Improvement of TPE Air Intake Hose Based on Optimization of Design and Material
Environmental regulations and fuel economy regulations on automobiles have been tightened recently. To counter this regulation, the global automobile industry is focusing its capabilities on weight reduction and continuously expanding and applying the fuel efficient turbo engine. However, with turbo-engine, turbulence occurs in the wheels of the turbochargers rotating at tens of thousands to hundreds of thousands of rpm, resulting in airflow noise. This noise is transmitted indoors through the air intake system, greatly weakening the vehicle's competitiveness. Therefore, in the case of turbo-engine, it is essential to ensure the high frequency noise reduction performance of the air intake system. The air intake system consists of an air cleaner, an air filter, an air intake hose and an air duct. The air flow noise of turbo-engine is mainly the emission noise emitted through the walls of the air intake system.
