Want to know what a timing chain is?

The timing chain connects the timing wheel and crankshaft of the engine cylinder head, and ensures the accuracy of the intake and exhaust time with a certain transmission ratio. To understand the use of the timing chain, you first need to understand the working process of starting.The working process of the engine mainly includes four steps: air intake, compression, work and exhaust.

The timing chain connects the engine cylinder head to the timing wheel of the crankshaft, and then cooperates with a certain transmission ratio to ensure the accuracy of the intake and exhaust time. To know the use of the timing chain, you first need to understand the working process of starting. The working process of the engine mainly includes four steps: intake, compression, work and exhaust.

The timing chain is the transmission chain between the engine spindle and the valve camshaft. Because a specific synchronization relationship must be maintained between the spindle angle and the camshaft angle, it corresponds to the time relationship between the cylinder reaching the upper stop point and the valve opening, so it is called positive timing.

So as to ensure that the engine cylinder can inhale and exhaust normally. The timing chain is the engine spindle and gas.The transmission chain between the door camshaft is called the timing chain because it is necessary to maintain a specific synchronization relationship between the spindle angle and the camshaft angle, which corresponds to the time relationship between the cylinder reaching the upper stop point and the opening of the valve.

The function of the timing chain is the same as that of the timing belt, which is the valve mechanism that drives the car engine. It can open or close the intake and exhaust valves of the engine at the right time. So as to ensure that the engine cylinder can absorb and exhaust normally.

What is a timing chain?

The timing chain connects the timing wheel and crankshaft of the engine cylinder head, and ensures the accuracy of the intake and exhaust time with a certain transmission ratio. To understand the use of the timing chain, you first need to understand the working process of starting. The working process of the engine mainly includes four steps: air intake, compression, work and exhaust.

Interpretation: The timing chain is an important part of the engine gas distribution system. It ensures the accuracy of the intake and exhaust time by connecting with the crankshaft and cooperating with a certain transmission ratio.

The working process of the engine mainly includes four steps: intake, compression, work and exhaust.

The timing chain is the evolutionary product of the development of the timing belt to a certain extent. The main function is to drive the gas distribution mechanism of the engine to open or close the engine inlet and exhaust valves at the appropriate time to ensure that the engine cylinder can inhale and exhaust normally.

The function of the timing chain is the same as that of the timing belt, which is the valve mechanism that drives the car engine.It can open or close the intake and exhaust valves of the engine at the right time. So as to ensure that the engine cylinder can absorb and exhaust normally.

How to install the Volvo 2.0t engine timing chain

gas timing, according to the requirements of the engine working cycle, open and close the intake and exhaust valve at the specified time to make the combustible mixture Or the air enters the cylinder and discharges the exhaust gas after combustion.

Turn the engine crankshaft so that the one-cylinder piston is at the upper stop point and fixed; align the timing mark of the camshaft gear with the timing mark on the chain and fix it; install the crankshaft drive sprocket, and ensure that the timing mark on the chain and the mark on the sprocket are in the same position.

The timing method of Volvo s40 is as follows.Align the marker link (orange) with the timing marker of the camshaft timing gear and install the timing chain. Rotate the camshaft timing gear assembly on the right row counterclockwise and tighten the timing chain in the middle. Align the marking chain (yellow) with the timing marking of the crankshaft timing gear.

First, use the card to jam the timing roulette to prevent the roulette from getting stuck during installation. Then find the colored chain teeth on the camshaft. Point the colored chain teeth at the small dots on the axle, so that the timing chain teeth are installed correctly. Then use a wrench to tighten the screw on the timing shaft.

The specific operation steps are as follows: install a new timing tensioner with a central bolt and fasten the bolt to 20Nm. Install a new idler belt and fasten the bolt to 24Nm. Align the timing mark. Install the central nut of the crankshaft.
