In the design stage of a diesel engine, we faced an issue that the valve bumping the piston,and therefore we analyzed the product quality, design data and the assembling technics. The product quality meets the design requirements, but the theoretic data which guide the timing system was wrong,and also the assembling technics had some defects. We have re-calculated and measured the correct theoretic data, and designed an artificial tool for fixing the crankshaft, and also improved the assembling technics. Finally, we obtained the anticipative effect. And currently, the artificial tool and the technics had been applyed in the production line.
