The function of the piston is to form a combustion chamber with the cylinder head, withstand the gas pressure in the cylinder, and through the piston pin and connecting rod The force is transmitted to the crankshaft. Figure 3-9 shows the cross-section of the piston structure. The piston is mainly composed of four parts: piston top piston skirt piston pin seat 3 and piston ring groove 4.
First of all, the engine housing The shell of the engine plays the role of isolation and sealing from the outside world, absorbing various forces during the operation of the engine.
The engine is composed of two major mechanisms: crank connecting rod 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. The inner surface of the cylinder is cylindrical.
1. The mesh distribution of German cars is also the reason why German cars are prone to burning oil. Because the cylinder piston of German cars adopts a mesh distribution, German cars can reduce wear and consumption during driving. Of course, the consequence of this is excessive oil consumption.
2. The main reason for burning engine oil is to use engine oil of poor quality or viscosity level that does not meet the requirements. The low quality level of the oil will lead to increased wear. In addition, the viscosity of the oil is too low.Or too high will cause poor engine lubrication, increase the wear of the piston ring and cylinder wall, reduce the sealing performance, and burn oil.
3. In addition, there are many reasons why German cars burn engine oil. Take Audi Volkswagen, a big oil burner, as an example.
4. The oil storage structure of the German car engine is different. It uses a design similar to a mesh structure. It can make the cylinder wall adsorb more oil, so that the piston ring is easy to form an oil film when moving, so it has a better effect on lubricating oil, but the loss of oil is also greater, so German cars will also burn oil.
The easiest way (for the new car): check whether the exhaust pipe smokes. If there is smoke, it is a two-stroke, and if there is smoke, it is a four-stroke.
The difference between two-stroke and four-stroke engines is simple from the appearance. It can be seen that the heat sink on the cylinder of the two-stroke engine is relatively large, the screws are relatively small, and the cylinder block is obviously longer than the cylinder head. The heat sink on the four-stroke engine cylinder is relatively small, with more screws, and the cylinder block and the cylinder head are almost the same length, and also It's just that the cylinder head is relatively long.
Look at the exhaust gas---The fuel of the two-stroke motorcycle is not burned for the second time. The utilization rate is relatively low, the combustion is insufficient, and its lubricating oil is mixed with gasoline, so the phenomenon of smoke can be seen, especially when driving at high speed.
