How to draw the timing chain of Chery Tiggo 1.6?

Remove the valve cover, shake the crankshaft to make the concave parts of the two camshafts face each other, and insert a special tool at the rear end of the camshafts to fix the two camshafts. Remove the bolts on the special bolt hole for fixing the crankshaft and the right lower part of the throttle valve on the cylinder block, and insert the special tool while shaking the crankshaft. When the crankshaft can't sway left and right, the crankshaft angle is fixed, and the positions of the four pistons are on the same horizontal plane, and the timing calibration is completed.

Working principle of timing chain

The job of timing chain is to connect the sprockets of crankshaft and camshaft with high-strength metal chain and keep them running synchronously. Due to the high-speed operation, rapid wear and high temperature between metals, it is necessary to design the corresponding lubrication system for cooling and lubrication.

At the same time, when designing the timing chain for the engine, there is still the problem of friction noise between metals. In order to solve this problem, manufacturers need to take various measures, such as designing optimized chains. In order to solve these problems, it is bound to increase the design and manufacturing cost of the engine.
