Metallurgical Problems of the Diesel Engine

The metallurgical problems of the Diesel engine consist more in selecting the most suitable material for a given application than in trying to find the solution for a chronic condition. Most of the problems encountered in operation are ones of design, but for economical reasons they often become metallurgical. It is believed that a more careful study of the details of design, with a view to eliminating localized overstress and providing better lubrication, will end most of the troubles. Where such consideration is given, the performance of the Diesel engine is most reliable, and many engines are building up records which rival those of the older reciprocating types of steam engines.
