Domestic goods should be self-improvement, independent brand small-displacement engine inventory

1. The all-firewood H20 engine is ultra-silently designed in terms of NVH, and the engine under the standard power The noise drops to 90 decibels, and the noise is 60 decibels at idle speed. In addition, the engine is also matched with the whole vehicle, and the whole vehicle is less noisy and more comfortable to drive.

2. Establishing the cultural attractiveness of the brand can eliminate the barriers and understanding of users in cultural cognition, and win people's hearts, which is especially important for the development of domestic products today.Nowadays, autonomous car enterprises have also made a lot of sound, such as Great Wall, Chang'an, BYD, FAW, Dongfeng and other car companies have all performed well.

3. The Shuike 6 is equipped with a TU5JP46-liter engine assembly matched with Peugeot 307, which is good. Small volume and light weight: The TU5JP46-liter engine adopts a small displacement design, with a small volume and relatively light weight. This makes the whole vehicle excellent in performance and more flexible and easy to drive.

4. Through the coupe SUV setting of T5 EVO, it can be seen that it is a model made for young people. Overall, it has high appearance, strong power, and ideal fuel consumption. As the saying goes, domestic products should be self-improvement! I look forward to the announcement of the price of this car and the market as soon as possible.

5. The engine has achieved technical indicators such as small displacement, high power and low fuel consumption, which strongly proves that domestic engines can also be so "powerful"! The 5T engine codenamed C15TDR will be installed on various flagship models under the Dongfeng Fengshen brand, and the latest Fengshen AX7 is also equipped.

6. Pentium T99 is the third SUV model under the Pentium brand after the rebranding. The first two models are Pentium T7T33, and the Pentium T99 is positioned as a medium and large SUV.

What is the world's smallest diesel engine

Diesel engine is an engine that burns diesel to obtain energy release. Now let me introduce you to the smallest diesel engine in the world.

The model of the smallest three-cylinder diesel engine is 0. Compared with four-cylinder or more-cylinder diesel engines, three-cylinder diesel engines are simpler in structure, smaller in size, lighter in weight, and lower in power and torque.

The smallest diesel engine can be 0.5 horsepower; the working process of the diesel engine is actually the same as that of a gasoline engine. Each working cycle also goes through four strokes: intake, compression, work and exhaust. The diesel engine inhales pure air during the intake journey.

Let me tell you about the smallest internal combustion engine in the world. Internal combustion engine: Internal combustion engine is a kind of power machinery. It is a thermal engine that burns fuel inside the machine and directly converts the heat energy it releases into power.

At present, the smallest diesel engine in China must be a single-cylinder diesel engine with a cylinder diameter of only 60 mm, such as the 160 water-cooled diesel engine and the 160F air-cooled diesel engine. Among them, the Type 160 water-cooled diesel engine was jointly developed by Xiangtan Diesel Engine Factory and Tianjin Internal Combustion Engine Research Institute, and passed the ministerial appraisal in December 1998.

What can a small engine do?

In theory, the engine of a small car cannot be used as an engine of a helicopter.The main reason is that the power is too low. Take the common small car Volkswagen Passat as an example, with a displacement of 8L and an engine power of about 100KW. The minimum power required for single-person helicopters is generally 3000-4000KW, and the difference between the two is 30-40 times.

And the most important thing is that the small-displacement engine can also meet the power needed by the car in the process of operation. The small-displacement engine has a good quality condition. Secondly, in the process of driving a car, we will basically find a relatively common phenomenon.

D. Lubrication system: The engine lubrication system is composed of oil pump, filter collector, oil filter, oil channel, pressure-limiting valve, oil gauge, pressure-sensitive plug and oil gauge, etc. The function is to transport a certain amount of clean lubricant to the surface of the relatively moving part to achieve liquid friction, reduce friction resistance, and reduce the wear of the machine parts.

Power the car. The engine is an energy conversion device. Its function is to convert the thermal energy of gasoline (diesel) into mechanical energy by burning and expanding the gas in the sealed cylinder.

Simply put, the engine is an energy conversion mechanism, that is, the thermal energy of gasoline (diesel). When the combustion gas expands in the sealed cylinder, it pushes the piston to work and converts it into mechanical energy, which is the most basic principle of the engine.
