|초록|| Transient heat transfer coefficients of gas at the cylinder head, piston and cylinder liner were determined by instantaneous surface temperatures and unsteady heat fluxes measured with instantaneous temperature probe and gas pressure in cylinder. The main results are as follows; (ⅰ) Transient heat transfer coefficients have great difference according to measurement points. (ⅱ) the heat transfer heat transfer coefficient is at vicinity of piston (ⅲ) the heat transfer coefficient of piston crown is shown about 3.4 times as high as that of cylinder head.
