Abstract
Diesel engines have a high thermal efficiency, but 20-30% of the input heat quantity is lost as the cooling loss. It is important to investigate the mechanism of wall heat transfer with impinging flame on the wall in improving the thermal efficiency. Therefore, in order to investigate the correlation of diesel flame and the wall heat loss, chemiluminescence photography, luminous flame photography and measurement of heat flux were carried out by using a wall insertion type constant volume vessel.
