How to install the timing chain of Volvo 2 0T engine?

Engine timing consists of two points:

1. The gas distribution timing, according to the requirements of the engine working cycle, open and close the exhaust valve at the specified time, so that the combustible mixture or air enters the cylinder, and the exhaust gas after combustion is discharged.

2. It is the ignition or fuel injection timing, according to the requirements of the engine work cycle, at the specified time in the combustion chamber to produce 15000 --- to 20000 volts of high-pressure sparks to ignite the compressed mixture, the diesel engine is at the end of the compression stroke, the high-pressure fuel injection ignition temperature has reached 2000 degrees of compressed air to make the engine work normally.

1) "Vehicle" means motor vehicle and non-motor vehicle.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

Steps: 1. Rotate the engine crankshaft so that the piston of one cylinder is located at the top dead center position and is fixed; 2. Align the timing mark of the camshaft gear (as shown in the upper part of the figure, the two red gears, generally small pits or arrows) to the timing mark on the chain (the link of the timing number is different from the color of other links), and fix; 3. Install the crankshaft drive sprocket (as shown in the lower part of the figure), and make sure that the timing mark on the chain and the mark on the sprocket are in the same position. 4. Finally, it is necessary to ensure that the three timing marks on the timing chain correspond to the two timing marks on the camshaft sprocket and one timing mark on the crankshaft sprocket.

The following methods can be used:

1. Align the marking link (orange) with the timing mark of the camshaft timing gear and install the timing chain.

2. Turn the camshaft timing gear assembly on the right row counterclockwise to tension the middle timing chain.

3. Align the marking chain (yellow) with the timing marking of the crankshaft timing gear.

Summary. <>

Hello, dear, glad for your question Timing belt Volvo engine does not use a timing chain, but a timing belt, Volvo timing belt, generally 4 years or 5 100,000 kilometers need to be replaced. Timing belts are rubber materials that will deteriorate over time and over the course of the engine, and need to be replaced regularly. The timing belt or chain of the car is to control the opening and closing of the valve by driving the camshaft when the crankshaft rotates through the movement of the piston.

Whether the Volvo low-power version of the engine is a timing belt or a timing chain.

Volvo Point is right.

Hello, dear, glad for your question Timing belt Volvo engine does not use a timing chain, but a timing belt, Volvo timing belt, generally 4 years or 5 100,000 kilometers need to be replaced. Timing belts are rubber materials that will deteriorate over time and over the course of the engine, and need to be replaced regularly. The timing belt or chain of the car is driven by the piston movement of Yanzaoxiang, and the crankshaft is driven to drive the rock camshaft to control the opening and closing of the valve.

Belt's. The method of vehicle alignment is: find the alignment mark marked on the engine's shed slag timing gear, the front end of the crankshaft and the flywheel, and the meaning of the mark is the position of the top dead center of the piston of the first cylinder of the engine; The timing can be corrected by finding the position.

The engine timing mechanism controls the time and duration of the engine intake and exhaust, and its function is to open and close the intake and fiber exhaust valves of each cylinder at regular intervals according to the working sequence of the engine, so that the fresh air chain quietly enters the cylinder and discharges the exhaust gas after combustion.

The intake wheel point belt can't go up.

This requires professional tools and technical advice to be operated by professionals. 1. Supplement: 1. Since most of the belts on the car are made of rubber materials, it is inevitable that they will gradually wear and age in the long-term high-temperature work.

Therefore, generally speaking, the manufacturer has regulations on the replacement time of the weighing belt on the car, and it is introduced in the vehicle's on-board maintenance manual.

It seems that the timing belt is used, and the specific morning stove can be seen at the material of the housing at the timing of the engine.

If Lu Ran dresses up the timing shell is made of plastic, then the engine of this car uses the timing belt, because the timing belt will age, so it needs to be replaced regularly, and the plastic material is generally used, which is easy to disassemble and assemble, and the timing belt does not need lubrication, so the sealing requirements are low.

If the timing cover is made of metal, then this engine uses a timing chain, because the timing chain needs oil lubrication to work, and the timing chain does not need to be replaced regularly, so the metal material is used for tightness and durability.

The above is a simple way to distinguish whether the timing belt or the timing chain used in the engine is used.

The biggest difference between timing belt and timing link is that the material is different, one is rubber products, and the other is metal products.

Advantages of timing belts:

1.Engines that use timing belts work with low noise.

2.The timing belt transmission resistance is small, and the transmission inertia is also small, which can improve the power and acceleration performance of the engine.

3.Timing belts are easier to replace.

Disadvantages of timing belts:

Timing belts are easy to age, and the cost of use is high.

Advantages of timing chains:

1.Timing chains have a long service life.

2.The failure rate of timing chain is low, and it is not easy to cause car breakdown due to timing transmission failure.

Disadvantages of timing chains:

1.The timing chain rotates noisily.

Volvo Cars' engine timing belt installation leather is as follows, the installation method is: the intake and exhaust camshaft is turned to the horizontal position, the crankshaft pulley is fixed to the front cover, and the combustion racket can be completed.

The engine's timing belt system works continuously with the high-speed operation of the car, so the Volvo Cars timing belt is always under high load, and it is easy to have various levels of wear. Therefore, it is necessary for the driver to check the timing belt in time to avoid serious problems such as engine failure caused by the fracture of the timing belt.

After all, the timing belt of the Volvo S80 car engine is not made of steel, and the belt can also be damaged. Therefore, it also needs to be replaced regularly. Generally, it needs to be replaced every 80,000 kilometers, and then every 60,000 kilometers.

The installation steps of Volvo S80L timing belt are: 1. Keep the piston of the first cylinder at the top dead center position, and the notch on the outer edge of the crankshaft timing pulley is aligned with the bulge on the pulley chamber; 2. Use a special tool to fix the timing pulley of the fuel injection pump, tighten the nut according to the specified torque, assemble the belt transition wheel assembly, and tighten the connecting belt transition wheel assembly; 3. Use the M8 process positioning bolt to position the camshaft timing pulley and the fuel injection pump timing pulley at the corresponding threaded hole position of the pulley chamber; 4. The timing belt assembly is sleeved into each transmission pulley in turn according to the requirements, the marks on the belt are required to be aligned with the marks on each pulley, the belt timing arrow is the same as the engine running direction, and the outer edge of the belt is flush with the outer edge of the camshaft to ensure that the end face of the belt is in the same plane; 5. Assemble the tensioner assembly on the pulley chamber, fix the tensioner assembly with hexagonal flange surface positioning bolts to ensure that the tensioner assembly can move freely, and ensure that the camshaft timing pulley and the fuel injection pump timing pulley can be lifted between the camshaft timing pulley and the fuel injection pump timing pulley after assembly, and the crankshaft pulley and the camshaft pulley can not have more teeth or wrong teeth, and the timing belt assembly can be bent when the assembly process is not right.
