How many valve technologies are used in cars now?

a) Structure and drive b) valve arrangement On modern cars, there are many new engines with a multi-valvale structure of 5 valves (3 in 2 rows) or 4 valves (2 in 2 rows) per cylinder. Compared with the traditional two-velve structure, these cars have the following characteristics.

Now most of the newly developed cars adopt a four-balbe structure.In the four-gate gas distribution mechanism, each cylinder has two intake valves and two exhaust valves. Volkswagen mostly adopts five-valve technology, such as the 20V engine of Jetta Wang, and the Baolai 8T engine is also five-valve.

Dual Intake Valve: A valve configuration used in some high-performance engines, by setting two intake valves in each cylinder to improve intake efficiency and increase power output.

What does the upper valve of the automobile mean

Multi-vene engine refers to the number of valves of more than two in each cylinder, that is, the three-gate type with two intake valves and one exhaust valve; the four-gate type with two intake valves and two exhaust valves; Five-gate type with three intake valves and two exhaust valves.At present, most of the multi-gale engines on cars are four-gale engines.

The function of the valve is to input air into the engine and discharge the exhaust gas after combustion. In terms of engine structure, it is divided into intake valve and exhaust valve.

The valve is the door used by the cylinder for intake and exhaust, that is, the intake valve and exhaust valve.

The function of the car valve is to input air into the engine and discharge the exhaust gas after combustion. In terms of engine structure, it is divided into intake valve and exhaust valve. The function of the intake valve is to suck air into the engine and mix it with fuel; the function of the exhaust valve is to discharge the combustion exhaust gas and dissipate heat.

In fact, there are two and three valves, four and five valves in each cylinder of the engine.The valve refers to the intake valve and exhaust valve of the cylinder. The intake valve is connected to the intake manifold, which is the inlet for the engine to inhale fresh air; the exhaust valve is directly connected to the exhaust manifold, which is the outlet for the engine to exhaust gas.

The role of the car valve

The function of the car valve is to input air into the engine and discharge the exhaust gas after combustion. According to the engine structure, the car valve is divided into intake valve and exhaust valve. The function of the intake valve is to mix the combustion of inhaled air and fuel, while the exhaust valve is responsible for discharging the exhaust gas after combustion and cooling it down. When the car valve is damaged, there are many symptoms.

How to adjust the valve of the car?

1. Make the timing pulley and the notation on the timing belt cover or the engine shell are positive. At this time, the inlet and exhaust valves of the first cylinder can be adjusted; then, by observing the rise of each cylinder valve or using a divider to rotate the flywheel by 120°, each cylinder piston can be placed in the stop point position on the compression stroke, so that All valve gaps can be adjusted.

2. The adjustment method of the valve gap of the car is as follows: rotate the crankshaft and alize the belt plate mark with the engraved line, which is the end of the one-cylinder or four-cylinder compression stroke.

3. Assemble the cylinder head. After the valve oil seal on the 465 cylinder head, the camshaft, rocker arm and rocker arm are assembled, the valve gap can be adjusted. How to use a wrench.

4. Determine the valve adjustment time: When the engine is working, the valve adjustment should be carried out at the positive timing position. If you are not sure about the timing position, you can refer to the engine manual or consult professional and technical personnel. Remove the valve cover: Find the valve that needs to be adjusted on the valve cover, use a wrench to remove the valve cover and expose the valve.

A broken car valveWhat are the symptoms

1. The symptoms of a broken car valve are: black smoke from the engine, air filter, and difficulty in starting. The car valve is a component of the engine, which is divided into the intake valve and the exhaust valve. The function of the intake valve is to inhale gas mixed fuel into the engine to bring power to the car, and the function of the exhaust valve is to exhaust gasoline and engine exhaust gas.

2. The symptoms of engine valve failure are as follows: it will affect the work efficiency of the engine and reduce the power of the car; there will be abnormal noise, the engine will have unstable idle speed or slow acceleration during operation, and the overtaking performance will also be reduced.

3. 3 symptoms of valve failure: valve damage will cause the inlet and exhaust duct to be loosely closed, resulting in engine leakage, cylinder pressure reduction, power reduction and fuel consumption increase. When it is serious, it will also cause black smoke from the engine exhaust, and the air filter to drain, and it will be difficult to start.

4. What will happen if the engine valve is broken? Symptoms of engine valve failure If the engine valve is damaged, there will be obvious problems. It usually makes abnormal sounds, such as the wailing sound of a car horn, unstable engine idling, slow acceleration, and lack of power, which are all obvious symptoms.

5. The symptom of the failure of the car valve oil seal is oil leakage; the oil leakage of the valve oil seal will accelerate the loss of oil; the rear exhaust pipe has blue smoke. This will cause the oil to leak into the cylinder, forming an "oil burning" phenomenon. The way to judge the damage of the valve oil seal is as follows: remove the intake manifold, and you can find that there is a black glue on the top of the valve.
