밸브오버랩기간 변화에 의한 흡기관 분사식 수소기관의 역화억제에 관한 연구
A Study of Backfire Control in a Hydrogen-Fueled Engine with External Mixture Using Changes of Valve Overlap Period
- 발행 : 2007.05.30
초록
To analyze the influence of valve overlap period on a backfire occurrence, the single cylinder research engine with MCVVT(Mechanical Continuous Variable Valve Timing) system is developed and backfire limit equivalence ratio defined as fuel-air ratio equivalence ratio at which backfire occurs is examined according to various valve overlap period. The MCVVT is the system to control valve overlap period by mechanical device. It is estimated that the lower valve overlap period has the higher backfire limit equivalence ratio though the same energy is supplied. When the valve overlap period is changed from 30
