A small type Diesel engine is operated with the fuel containing various sulphur compounds and under various engine conditions. These tests show (1) the top-ring wear is large owing to the fact that it is surrounded with the combustion products, so when gastightness of the top-ring is inadequate, the 2nd-ring wears in the same order, (2) the more sulphur is contained in the fuel and the lower the temperature of cooling water goes down, the more corrosive wear increases. The cylinder surface is corrorded by the condensed liquids of the engine exhaust gas, containing much SO3 the liquid easily penetrates into the lubricating oil, and attacks the metal surface. Chemical analysis shows that the SO3 presents itself so much in the exhaust gas, as the ratio SO3/SO2 is about 10%.
