Abstract

An engine lubrication system comprises a cabinet. A turbocharger, a lubricating oil tank, an oil cooler, an oil pump and an oil filter which are connected sequentially are arranged on the cabinet. The oil filter is connected with a main oil way in the cabinet. A bent axle hole and a camshaft hole are formed in the cabinet. The main oil way is communicated with the bent axle hole, the camshaft hole and mounting holes, used for mounting hydraulic tappets, on two sides of the camshaft hole. An oil storage tank communicated with the bent axle hole, the camshaft hole and the mounting holes is arranged at the bottom of the cabinet. An oil drainage hole is formed in the lower portion of the oil storage tank. The engine lubrication system is simple in structure, bent axle kinematic pairs, camshaft kinematic pairs and the like can be lubricated at different angles, and lubrication efficiency is improved.

Description

technical field [0001] The invention relates to an engine lubricating system, in particular to a multi-cylinder horizontally opposed engine lubricating system. Background technique [0002] The lubrication system is one of the important components of the engine. During the operation of the engine, the engine oil plays a very important role. It not only plays the role of lubrication, but also plays the role of sealing, cooling and buffering. The Chinese patent with application number 201220721229.0 discloses an engine lubricating structure, including an oil cylinder filter installed in the left box, an oil pump arranged on the right box, an oil filter arranged on the right box cover, and It is connected to the oil storage cavity at the oil cylinder filter, the oil pump, and the oil passage of the oil filter; the oil passage extends upwards from the oil filter, and extends above the crankshaft to the right box, Then extend upwards from the right case body to the cyl...
