중형 디젤 엔진을 위한 하이펄스 터보챠저 과급 시스템 개발

In order to improve engine performance while overcoming the weak points of 2-Pulse and MPC(Modular Pulse Converter) turbocharging system, a new turbocharging system, "Hi-Pulse system", has been introduced and developed for medium speed diesel engines, HYUNDAI HiMSEN engines. Hi-Pulse system is to utilize not only the benefits of MPC system at higher load but also the ones of Pulse system at lower load. Therefore, the specific fuel oil consumption and NOx emission were lowered when comparing with the 2-Pulse and MPC system. Performance simulation carried out to optimize intake and exhaust timing and exhaust duct arrangement and improve the performance of Hi-Pulse system engine.
