[論文] LPG를 使用하는 機關에서 空燃比가 性能에 미치는 影響에 關한 實驗的 硏究
정태용(T.Y.Chung),허문회(M.H.Hur) 한국자동차공학회 1983 오토저널 Vol.5 No.4
Experiments about the influence of air-fuel ratio on the engine performance by attaching the LPG fuel system to a gasoline enging are studied.<br/> The max torque is occurred in the vicinity of excess air factor 1. 0~1. 1.<br/> When the excess air factor is about 1.1~1. 4, the brake thermal efficiency is the largest.<br/> When the engine speed increases, the excess air factor of the minimum specific fuel con-sumption decreases from 1.4 to 1.1.
저온 플라즈마 장치에서 NOx 및 SOx 저감시 NH₃와 C₂H₄의 첨가 효과에 대한 실험적 연구
김명수(M.S.Kim),김홍석(H.S.Kim),정태용(T.Y.Chung) 한국자동차공학회 1998 한국자동차공학회 춘 추계 학술대회 논문집 Vol.1998 No.11_1
To decrease NOx and SOx using PPCP(Pulse-induced Plasma Chemical Process), this study is tried to obtain the relations and the basic data under the various conditions such as the initial concentrations of NOx and SOx. the additional amount of NH₃ and C₂H₄ gases, gas flow rate, the concentration of oxygen, input voltage and frequency etc. Especially, this study is focused on the effects of the additionals NH3 and C₂H₄ on the decrease of NOx and SOx.<br/>
