An Experimental Study on the Development of Muffler with Cotroller Sensing Exhaust-gas Pressure in Exhaust System

배기계의 배기압 감응형 제어 머플러 개발에 관한 실험적 연구

This study is on the development of a new muffler composed of a valve system using an elasticity or spring. The valve system using the elasticity of spring is set along the exhaust-gas flow and designed to work itself alone the driving condition of a engine. By that reason the engine capacity is so enlarged that a muffler with controller sensing exhaust-gas pressure is able to be satisfied to noise reduction and- power enlargement more than conventional muffler. The purpose of this study is to develope the new muffler which has more noise reduction and power enlargement than conventional muffler and electric-control muffler.
