Which country in the world has the best automotive engine technology

Germany. The engine of the world's first car was invented by the Germans. It can be said that Germany has a very long history of developing and manufacturing engines. In addition, the Germans are very high in mechanical design, so even if the engines they make are dismantled and studied, it is difficult to achieve the same level of manufacturing technology if they want to imitate them.

The best car engine in the world. The recognized BMW engine is the best. It used to make airplanes. The world's most durable engine in the world.The most durable engines are Honda, Toyota, Mercedes-Benz, Volvo, Jaguar, Lexus, Fiat, Ford, Nissan, Land Rover. The following is a detailed introduction to the failure rate of the Top1 Honda engine.

The world's top ten best engines: BMW, GM, Ford, Volkswagen, Nissan, Honda, Chrysler, Toyota, Mazda, Mercedes-Benz. The brand that BMW (Germany) has won the title of "Ward's Top Ten" the most is BMW, which has won 32 awards.

which country is the c919 engine from

No, it still uses the LEAP-X1C engine China Commercial Aircraft Limited The responsible company (China Shangfei) and CFM International (CFM) jointly announced that the technology-leading new aircraft engine LEAP-X1C was selected as the only engine designated from Western countries for the new C919 single-channel passenger aircraft.

The United States. At present, the test flight progress of China's C919 large passenger aircraft is very good. If all goes well, the first five aircraft can be delivered to domestic users this year for the operation of domestic routes. However, some netizens are excited and worried.That is, the core technology of C919 is still monopolized by the West, and now the C919 aircraft is still using American engines.

c919 engine is made in the United States. As the "flower of aviation", aviation engines can be said to be a complete experience of aviation technology and industrial accumulation. The engine of C919 is a LEAP-X1C engine.

The engine used by C919 is the dual-engine turbofan medium CFM LEAP-1C of cfm (International Engine Company). CFM International Company delivered the first LEAP-1C engine to China Shangfei Company on July 22, 2015. The first C919 aircraft will be equipped with the first engine to prepare for the off-line within the year and the first flight after that.

There are several countries in the world that can independently produce aviation engines

1. In fact, the reason why China has spent so long in this field is that it is mostly used to develop aviation engines. How difficult it is to manufacture aviation engines, according to the At present, only five countries in the world have the technology to manufacture aviation engines independently.

2. The threshold for manufacturing aircraft engines is very high. Nowadays, only the United States, the United Kingdom and France in the world have the technology of independent research and development of civil aviation engines. If military aircraft technology is added, there are only five, namely the United States, the United Kingdom, France, Russia and China.

3. The countries that can develop turbine fan engines on their own are the United States, the United Kingdom, Russia, Ukraine, France, China and Japan.

4. For example, South Korea, Indonesia, Brazil, Japan and other countries can develop their own aircraft. However, only the United States, the United Kingdom, France, Russia and China can develop aircraft engines independently.

5. There are only five countries that can really be called major aviation, that is, the five permanent members of the United Nations, the United States, the United Kingdom, France, China and Russia. Only these five countries can independently develop the heart of aviation: aviation engines.

6. Therefore, China has become the fourth country in the world that can independently develop advanced fighter jets, engines and missiles at the same time. The rest of the countries, such as Sweden, Israel, Japan, etc., use American engines.

Why does the country prohibit the middle engine?

1. The country prohibits the middle engine, which is because the middle engine is rarely used, mainly for the following reasons: high cost, safety and practicality. High cost: Compared with the front or rear engine, the design and manufacture of the middle engine is more difficult, requiring a higher level of technology and production costs, so the price is also higher.

2. The main reason why the country prohibits mid-positioned engines is for safety reasons. Because the front engine can buffer and reduce the impact force, and the engine is in the middle, resulting in the narrowing of the carriage and the driver and passengers are too close to the engine. If a traffic accident occurs, it is easy to cause the engine to invade the cab.

3. China has not banned the research and development and introduction of mid-engines, but there are few mid-engine models sold in the Chinese market.Because of the high research and development costs and technical requirements of mid-engines, many automobile manufacturers do not manufacture mid-engines.

4. Because the middle engine is prone to oversteering once it is out of control or slips at high speed. Due to the high research and development cost and technical requirements of mid-engines, many automobile manufacturers do not manufacture mid-engines, so there are few mid-engine models sold in the Chinese market.
