Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
An exhaust camshaft apparatus of an automobile engine as provided in fig. 1 and 2, comprising: the bowl blocking mechanism comprises a front end bowl blocking mechanism 2 and a tail end bowl blocking mechanism 9, the front end bowl blocking mechanism 2 is communicated with a main oil pipe of an engine, the front end plug 7 is connected between the front end bowl blocking mechanism 2 and the camshaft 1, the camshaft 1 is a hollow cylinder, one end of the camshaft 1 is communicated with the front end plug 7, the other end of the camshaft is communicated with the tail end bowl blocking mechanism 9, the front end plug 7 is provided with an oil flow hole, and engine oil in the front end bowl blocking mechanism 2 enters the camshaft 1 through the oil flow hole. Specifically, work at the exhaust-gas process at automobile engine, exhaust camshaft device is under the drive of bearing, quick rotation, for guaranteeing that camshaft 1 reduces the friction at the rotation in-process, need lubricate camshaft 1, because camshaft 1 of exhaust end is less to the demand of machine oil compared in the side camshaft of admitting air, consequently, need control the machine oil volume that machine oil got into exhaust camshaft, through the structural feature of redesign camshaft, through the consumption of the supporting journal 8 to machine oil of calculating exhaust camshaft device, design the size of front end cap 7 flow oil hole, when guaranteeing supporting journal 8 lubricated, make machine oil pressure satisfy the demand of variable valve timing system to machine oil.
