|초록||The instantaneous surface temperature and unsteady heat flux on the cylinder head are measured and analyzed in order to obtain the basic data for the design at the combustion chamber of DOHC engine. The main results are as follows; ⅰ) The highest wall temperature is shown at vicinity of the exhaust valve bridge and the temperature of the exhaust valve bridge is continuously increased in the exhaust stroke. ⅱ) The wall temperature at the exhaust valve head is about twice as high as that of the intake valve head. ⅲ) The distribution of the heat flux has different tendency to that of the wall temperature and the heat flux of the exhaust valve bridge has a small value comparatively.
