Abstract

The invention discloses a cam shaft used for an internal combustion engine. The cam shaft comprises a support shaft, and an air inlet cam, an exhaust cam and a brake cam which are sheathed and fixed on the support shaft, wherein the exhaust cam has a working section with the angle of 120.5 degrees, a transition section with the angle of 30.5 degrees, the base radius of 30+ / -0.05mm and the whole outline height of 38.56+ / -0.04mm. According to the cam shaft, the exhaust cam is designed aiming at the structures of internal combustion engines of new automobile models, and the maximum open degree of an exhaust valve is guaranteed by the design of the exhaust cam, so that thorough exhausting can be guaranteed; due to the design of the base radius, the exhaust cam is enabled to have enough rigidity; due to the design of the angle of the transition section, the noise of the internal combustion engine can be reduced. The invention also discloses the internal combustion engine provided with the cam shaft.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a camshaft. The invention also relates to an internal combustion engine having a camshaft as described above. Background technique [0002] In the structural design of the internal combustion engine, the camshaft is a part used to control the opening and closing of the intake valve and exhaust valve. The camshaft includes a support shaft and intake cams, exhaust cams and brake cams that are sheathed and fixed on the support shafts, wherein the intake cams, exhaust cams and brake cams are used to control the intake and exhaust valves. The main part of the opening and closing movement of the cam, so the reasonable design of the shape of the cam has a certain influence on the working performance of the internal combustion engine. There are four main parameters that determine the shape of the cam, that is, the working section of the cam, the transition section, the...
