What is the piston of the car? Is there a picture? What is the specific function?

The main function of the piston is to withstand the combustion pressure in the cylinder and transmit this force to the crankshaft through the piston pin and connecting rod.The basic structure of the piston can be divided into top, head and skirt. The piston also forms a combustion chamber with the cylinder head and cylinder wall.

What is the function of a car piston? Let's learn about it together. It withstands gas pressure and transmits it to the connecting rod through the piston pin to drive the crankshaft to rotate. As an integral part of the combustion chamber, it forms the combustion chamber together with the cylinder head and cylinder wall.

The function of the automobile piston is to bear the pressure of the combustion gas and transmit it to the connecting rod through the piston pin to make the crankshaft rotate to output power. The piston is one of the most important parts in the engine with the worst working conditions. It is the "heart" of the automobile engine. It is subjected to the alternating mechanical load and heat load, and the top of the piston is also one of the components of the combustion chamber.

The piston is the "heart" of the automobile engine, which bears alternating mechanical and thermal loads, and is one of the key components in the engine with the worst working conditions. The function of the piston is to withstand gas pressure and drive the crankshaft to rotate through the piston pin to the connecting rod. The top of the piston is also a component of the combustion chamber.

I want to buy a second-hand Haojue 125-2 motorcycle, but I don't know whether the engine is a small trainer or a top-bar machine, _Baidu...

1. The Haojue HJ125-2 series is a Wuyang model and a car modified from the Wuyang model. Their engine is a top-bar machine, and this series is also the cheapest model of Haojue. One of the numbers, the price of the small chain machine is relatively high, and it is generally installed in more expensive cars. The 125-2 series of cars is mainly economical and practical, and it is very suitable to adopt a top rod machine.

2. Generally speaking, the chain engine has low vibration, fast speed and good comfort, which is suitable for areas with better road surfaces. If you prefer lightning-like pleasure, you are right to choose a chain machine.

3. Chain machine. Suzuki engines do not have a top-bar machine. Only cars with Suzuki's sign but use other styles of engines will have a top-bar machine.Whether it is a chain machine, you can check whether there is something that looks superfluous on the edge of the middle cylinder, which is used to automatically adjust the chain.

4. The chain machine and the top rod machine are the two-stroke gas distribution methods of four-stroke motorcycles, that is, the parts that control the opening and closing of the valve are the timing chain and the valve top rod respectively. The balance shaft is installed in front or behind the crankshaft to balance the inertial vibration generated by the crankshaft in operation, and its weight is opposite to the crankshaft.

5. The drive parts of the chain engine are a set of sprockets, similar to the common power transmission devices of motorcycles, mainly composed of large and small sprockets and chains. The driving parts of the thimble engine are relatively simple, mainly composed of upper and lower rocker arms and putters. The putter is also called thimble. In order to distinguish it from the chain engine, this engine is also called the top-bar engine.

6. The small chain machine has low noise, fast acceleration and high speed; the rod machine is trouble-free and durable. In fact, the performance of the chain machine is excellent, but the domestic machine is still a pole machine with mature technology. The Haojue car pole selector is a wise move to save money and worry. If the price is more than 6,000 yuan, choose the chain machine. If it is a middle and low price, choose the top rod machine, except for the curved beam car.

Where is the Yamaha engine cylinder located?

1. The timing wheel is located on the left side of the engine, and the positions of 1 and 2 cylinders are relative.

2. Refer to the picture below for the position of the motorcycle cylinder. The engine is attached to the box, and the cylinder generally has a heat sink on the outside.

3. Refer to the following pictures. The engine is attached to the box, and the cylinder generally has a heat sink on the outside.

4. Hello. The cylinder is the heart of the engine! Of course, it's inside the engine! [ If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

5. The position of the cylinder inside the engine. The position of the cylinder in the engine. For example, if this car is a 4-cylinder engine, then there are 4 cylinders in this engine.This is also the most important and core part of the engine work. The cylinder is the one that compresses and burns the gasoline.

6. Hello, in the engine cylinder block, remove the spark plug and you can see it. I hope my answer can help you. I wish you a happy use of the car! [ If there is a problem with the car, ask the car master. 4S store professional technician, 10 minutes to solve.

From which aspects should the engine oil be checked?

1. If the oil consumption is too fast, it may be that the engine is leaking or there is oil burning. The oil consumption can be judged by the driving computer display. If this function is not there, pull out the oil meter regularly for inspection. Once it is found that the oil consumption is too fast, it should be dealt with in time. The repair agent can solve the problem of burning oil.

2. The main reason for burning engine oil is that the internal sealing of the engine is not good. It can be checked whether there is too much carbon in the combustion chamber. Too much carbon in the combustion chamber is one of the fundamental problems that cause oil burning, and the fuel quality and the driver's driving habits are the key reasons for the carbonization of the engine.

3. Judge whether the exhaust pipe will produce blue smoke. Inspection method: When the engine is not running for a long time, the oil will flow into the cylinder through the gap of the valve oil seal under the action of gravity. As soon as the engine is started, the oil in the cylinder will burn under the action of high temperature and high pressure, producing a large amount of blue smoke.

Engine basic parts structure diagram (super detailed)

Automotive engineThe structure diagram is as follows: The engine is composed of two major mechanisms: crank connecting mechanism and gas distribution mechanism, as well as five major systems such as cooling, lubrication, ignition, fuel supply and start-up system. The main components include cylinder block, cylinder head, piston, piston pin, connecting rod, crankshaft, flywheel, etc.

Only four-stroke engines are equipped with camshafts, valves and other gas distribution mechanisms. These mechanisms mainly include camshaft, valve, valve seat, valve spring, valve spring seat, air-spliting gear, air-spliting active gear, valve strut (puter rod in the overhead valve structure), rod guide (or rocker arm, Rocker arm shaft) and other parts, as shown in Figure 1-Figure 1-7.
