The so-called diesel engine, as the name suggests It is an internal combustion engine that uses diesel as fuel. A certain amount of power can be obtained by burning diesel. Before the invention of the diesel engine, people had been using steam engines. However, due to the extremely low efficiency of steam engines, it was difficult to support high-power work. It was at this time that the diesel engine came into being.

In 1892, French German engineer Diesel officially began to develop diesel engines. After five years of hard work, a new four-stroke diesel engine was born. The improvement of thermal efficiency makes the machine work faster. Therefore, the emergence of diesel engine quickly attracted widespread attention.

But because the diesel engines at that time were too bulky, people could only do fixed work. With continuous improvement, diesel engines were widely used in automobiles, ships, and stationary industries at the beginning of the 20th century.

In the 1920s, diesel engines officially entered the high-speed era. With the gradual improvement of turbocharging technology, diesel engines have gradually evolved into an important part of automobile power machinery. Late 1970s. Volkswagen uses diesel engines as the engines of its cars.

In the early 1990s, four-cylinder turbocharging technology was successfully applied to diesel engines, becoming the world's first four-cylinder turbocharged diesel engine. At that time, this technology was only available to Germany. It was gradually introduced into our country in the 21st century.

With the successful development of Germany's four-cylinder turbocharged diesel engine, there was a rush of pursuit in various European countries. During this period, some of our current Familiar companies quickly emerged.

In the 21st century, European countries at that time were already quite proficient in diesel engine technology. In 2004, more than half of the models in the European new car market used new diesel engines. engine.

However, among developed countries, one country is an exception, and it is the United States. In the new car market of the United States, the number of vehicles that can use new diesel engines is less than the total number of new cars. 1%.

The reason why the United States does not use new diesel engines is definitely not because of diesel engine performance problems, but also based on the actual situation. At that time, the United States had the lowest gasoline prices in the world. Under such circumstances, how could automobile manufacturers ignore their huge market share?

In addition, as a major industrial country at that time, the United States’ carbon dioxide emissions were not low. Under such circumstances, the United States will never give up the gasoline engines it used before and switch to diesel engines.

But after 2006, this situation completely changed. As the price of gasoline continues to rise, gasoline engines in the United States are no longer the only standard feature of new cars. The rising star diesel engine has quickly occupied 80% of the U.S. automobile market share.

At that time, there were at least 13 new cars in the United States equipped with new diesel engines. In addition, six new cars were warmed up in the second half of the year. , at least 20 car models are equipped with new diesel engines.
