Abstract

The invention provides an engine cylinder head assembly, relates to automotive engine parts, and solves the problem of increasing probability of damage to the cylinder head of an existing engine cylinder head assembly. The engine cylinder head assembly comprises a cylinder head, a cylinder head cover fixed to the cylinder head through sealing, and a variable valve lift actuating device mounted in a sealed chamber formed by the cylinder head and the cylinder head cover. The variable valve lift actuating device comprises a camshaft, a swing arm adjusting frame, a swing arm movably connected with the swing arm adjusting frame. A first fixing device is arranged between the camshaft and the swing arm adjusting frame, fixedly connected with the cylinder head cover, and is used for supporting the camshaft and movably connecting with the swing arm adjusting frame.

Description

technical field [0001] The invention relates to automobile engine components, in particular to an engine cylinder cover assembly. Background technique [0002] The engine cylinder head assembly includes cylinder head, cylinder head cover and variable valve lift (Variable ValveLift, referred to as: VVL) driving device and other parts, wherein the cylinder head and cylinder head cover are fixedly connected to form a closed chamber , VVL driving device and other parts are set in the chamber, and some components of the VVL driving device are fixed on the cylinder head or cylinder head cover. [0003] The VVL driving device is a device that can change the valve lift according to different working conditions of the engine. Among them, the valve is used to input fuel into the engine and discharge the exhaust gas after combustion, and the valve lift refers to the height that the valve moves from just opening to fully opening, that is, the opening height of the valve. The engine us...
