DOHC 가솔린기관의 연소실 벽표면순간온도 및 비정상 열유속 측정 및 해석(제3보 : 실린더 라이너에 관한 연구)
Measurement and Analysis of Instantaneous Surface Temperature and Unsteady Heat Flux at Combustion Chamber of DOHC Gasoline Engine ; Cylinder Linder
초록
Instantaneous temperature probes were manufactured by pressing method. By using these probes, the instantaneous surface temperature and unsteady heat flux in the cylinder liner of DOHC engine were measured. The main results are as follows; ⅰ) the instantaneous surface temperature of cylinder liner are affected by the contact of piston ring as well as burning gas. ⅱ) the wall temperature of the siamese portion is much higher than other parts. ⅲ) it was shown that the rising trend of heat flux by burning gas are nearly limited to the 1/2-stroke distance from the top of cylinder liner.
