Engine block is a main component in a small size air-cooled diesel engine, its structure has a very important influence on the diesel engine weight. We use ANSYS finite element technology to analyze the strength of the structure of the Light-duty 170F diesel engine and find some weaknesses and thus provide theoretical foundation for strengthening the 170F engine block and further improving its structure. The improvement result indicates that the optimized engine block is lighter 1.282 kg in weight which has been reduced 11.93 percent compared with the former structure.
