Description

Technical Field

[0001] The utility model relates to the technical field of engine cylinders, in particular to a noise-reducing engine cylinder. Background Art

[0002] The engine block is the main body of the engine. It connects the cylinders and the crankcase together. It is the supporting frame for installing the piston, crankshaft and other parts and accessories. It is the assembly basis of various mechanisms and systems on the engine. The material of the engine block is generally gray iron, because the working environment of the cylinder block is humid, that is, the cylinder block has high strength, high hardness and high wear resistance. The disadvantage of gray iron is that it is heavy, so more and more cylinder blocks are now made of aluminum alloy materials. Aluminum alloy materials can reduce the weight of the cylinder block. There are many kinds of engine cylinder blocks currently applicable to the market, but there are still some disadvantages;

[0003] For example, in actual use, a general engine cylinder will vibrate violently and make some noise after the engine runs for a long time. The noise will have an impact on people's psychology. At the same time, the long-term operation of the engine will generate a lot of heat inside the cylinder. Failure to cool down in time will cause the engine parts to deform due to heat. In addition, the inside of the cylinder is cooled by coolant. If the coolant water pipe is not fixedly installed, the engine vibration will cause the water pipe to vibrate and break, and the coolant cannot be transported normally inside the cylinder. Therefore, we propose a noise-reducing engine cylinder to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a noise-reducing engine cylinder to solve the problem of the current engine cylinder proposed in the above-mentioned background technology. After the engine runs for a long time, the engine cylinder will vibrate violently and emit some noise, which will have an impact on people's psychology. At the same time, the long-term operation of the engine will cause a large amount of heat to be generated inside the cylinder. Failure to cool down the engine in time will cause the engine parts to be deformed by heat. In addition, the inside of the cylinder is cooled by coolant. If the coolant water pipe is not fixedly installed, the engine vibration will cause the water pipe to be damaged by vibration, and the coolant cannot be normally transported inside the cylinder.
