Engine and vehicle

Abstract

The invention discloses an engine. The engine comprises a cam shaft, a front cover and a VVT (Variable Valve Timing) controller, wherein an OCV (Open Circuit Voltage) control valve is mounted on the front cover; an oil path which separately communicates with the OCV control valve and a hydraulic source is arranged in the front cover; the OCV control valve communicates with the VVT controller through the oil path; and corresponding positions of a mounting position of the OCV control valve arranged on the front cover and the front end of the cam shaft are located on the different heights. Through the design, the OCV valve is mounted on the front cover; through design of the inner oil path, the OCV valve communicates with the VVT controller and the hydraulic source; and due to the structure,the extension length of the cam shaft is shortened, the stability of a VVT system is improved, the VVT controller is welded with the front end of the cam shaft without needing welding any longer; andmoreover, by adopting the design of mounting a positioning assembly, connection between the VVT controller and the cam shaft is realized. Through the manner, the assembling coaxiality is improved moreeasily, the axial length of the engine is shortened, and entire-vehicle design is easy. The invention also discloses a vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicle equipment, and more particularly, to an engine and a vehicle. Background technique [0002] At present, VVT (variable valve timing) technology has been widely used in the engine field. The air volume is optimal and the combustion efficiency is improved. The advantages are fuel saving and large power-to-liter ratio. [0003] The oil supply path of the engine using VVT is generally located at the front end of the cylinder head or in the cover, and its disadvantage is that the oil circuit is complicated. VVL (variable valve lift) technology is also widely used in engines, and the arrangement of VVL will make the engine arrangement more compact. However, when VVT and VVL are applied to the engine at the same time, the overall layout is very complicated, and there are certain structural defects. The specific reasons are as follows: [0004] In the prior art solution, the OCV valve (oil contr...
