Introduction to aligning the timing chain on a Polo 1.4: First, remove the two camshaft rear covers. There are two holes on the camshafts; use a special tool to lock them in place. Align the crankshaft to the top dead center, and then install the chain. The "timing belt" or "timing chain" is a crucial component of the engine. Here are some related details: 1. The main function of the "timing belt" or "timing chain" is to drive the engine's valve train, ensuring that the engine's intake and exhaust valves open and close at the appropriate times to allow the engine's cylinders to intake and exhaust air normally. 2. The working principle of the timing chain: It uses a high-strength metal chain to connect the sprockets of components like the crankshaft and camshaft, keeping them synchronized. Due to the high-speed operation between metal parts, wear is rapid and temperatures are high, so a corresponding lubrication system must be designed for cooling and lubrication. Additionally, the use of a timing chain in engine design also presents the issue of friction noise between metal parts. To address this, manufacturers need to take various measures, such as designing optimized chains. Solving these issues inevitably increases the design and manufacturing costs of the engine.
