Studies were carried out on the high temperature corrosion of exhaust valve in a diesel engine, by the procedure of accelerative testing. The authors could, therefore, separate the effects of various factors which affect the corrosion rate every two hours of testing. As the result of experiments, the following conclusions were reached. (1) Effects of the temperature and the air factor on the high temperature corrosion are both remarkable. However, the effect of the temperature is greater than that of the air factor. Consequently, unlike the case of a spark ignition engine, a decreasing tendency of corrosion rate is observed as the air factor increases to a large value. (2) The effect of vanadium in the fuel on the high temperature corrosion is small compared with those of the temperature and the air factor. (3) The corrosion rate is proportional to the stress, though the effect of stress is comparatively small. (4) The corrosion rate is proportional to the product of impact energy and the number of impacts during the prescribed period.
