Zusammenfassung:	The utility model discloses a diesel engine camshaft structure capable of effectively reducing noise. The diesel engine camshaft structure comprises a camshaft body, an oil pump driving cam, a first rotating part, an air inlet cam, an exhaust cam and a second rotating part are sequentially arranged on the camshaft body from one end to the other end of the camshaft body. The exhaust cam is provided with a protruding part and a round body part, the protruding part is provided with a notch extending in the radial direction, a protrusion extending in the axial direction is arranged in the notch, and a plurality of grooves are formed in the surface of the round body part. The oil pump driving cam, the air inlet cam and the exhaust cam are the same in structure. The notch is formed in the protruding portion of the cam, the groove is formed in the round body portion, the contact face of the cam and the tappet can be reduced, noise generated by friction is reduced, the protrusion is arranged in the notch of the protr
