大众1.4si拆解之正时缸盖篇（The dismantling of the public 1.4si when the cylinder head chapter） The Volkswagen 1.4TSI engine for the first part of the golden section (click to view details), analysis of dismantling and technology of turbocharger, two independent cooling system and external exhaust pipes long hair components have been presented in detail for everybody, but in this article I will for you to uncover the core power of mass Bob part of the upper truth, detailing the 1.4TSI engine timing system and the internal structure and the head part are hidden behind the story for you. Note: the hair part: engine cylinder block and head, connecting rod, crankshaft, camshaft and other core components of the engine; the engine long hair part: Based on the engine assembly and finally form a complete engine plug-in components; The 1.4TSI engine timing system In the dismantling of 1.4TSI engine Bob part, the engine timing system related to the implementation of components of the split is the first to process, and this process has the chief executive why? The timing system and for what? In this chapter, let us into the formal dismantling, took the lead into the world is the engine principle: What is the engine timing system? The timing system is an important part of the engine valve mechanism, is one of the important factors which ensure the engine breathe. Mainly through the control valve opening and closing time, realize the time to open and close the inlet and exhaust valve accurately, make a fresh charge of air and waste gas discharged from the cylinder into the cylinder, and ensure that the engine power output, with normal, good. Implementation of system components is. Now is when most of the engine working process of the system, which is mainly composed of a chain or belt driven by the crankshaft camshaft running through the working surface of the cam rotating top pressure valve tappet, and push the valve movement into the cylinder, so as to realize the valve is opened; rotate
