When disassembling and installing the engine crank connecting rod mechanism and gas distribution mechanism, which parts have cooling water sleeves

According to the number of cylinders, it can be divided into single Cylinder engine and multi-cylinder engine.Modern cars mostly use three-cylinder, four-cylinder, six-cylinder and eight-cylinder engines. According to the cooling method, it can be divided into water-cooled engine and air-cooled engine. The water-cooled engine has uniform cooling, reliable operation and good cooling effect, and is widely used in modern vehicle engines.

The crank connecting rod mechanism consists of three parts: the fusele group, the piston connecting rod group and the crankshaft flywheel group.

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 working cavity of the resurrected plug internal combustion engine is called a cylinder, and the inner surface of the cylinder is cylindrical.

The air cylinder block of the fusele, the air cylinder block is the assembly base of various mechanisms and systems of the engine, and is the most important part of the engine.The cylinder block has water-cooled cylinder block and air-cooled cylinder block. The water-cooled cylinder block is generally integrated with the upper crankcase.

Crank connecting rod mechanism The crank connecting rod mechanism is the main moving part of the engine to realize the working cycle and energy conversion. It consists of a fusele group, a piston connecting rod group and a crankshaft flywheel group.

How to replace Wang Chai's engine water cover if it is broken?

1. First, remove the large flywheel of Weichai p10, and see the oil pump in the lower left corner. Swing out three bolts seven times. Then the oil pump is removed. Finally, fill the new pump with oil and install it before using it.

2. When the SCR system fails, troubleshooting should be carried out first to determine that it is a problem with the post-processing assembly. If the post-processing assembly fails, you can consider replacing the entire post-processing assembly to ensure that the system can work normally.

3. This fault is obviously the air entering the oil line. It should be that the oil pipe connecting the fuel tank is broken, and the fuel tank needs to be replaced.

4. The correct way to replace the antifreeze is as follows: first, drive the vehicle into the lifting machine operation area, and open the coolant expansion kettle lid to ensure that the engine is in a cooled state.
