| Abstract: | In order to solve the problems occurring during test of WD618 44 diesel engine, such as collision between
piston and valve, cam and tappet's wear, dynamic calculation is taken for valve train. On the basis of calculation, cam
profile is redesigned. Test results prove that all Problems can be settled successfully. |
