Fuel consumption decreased by 70% year-on-year.

On July 30, 2004, Cui Xun’s day was exciting.

On this day, Cui Xun rushed from Yanji to Beijing and submitted a patent application for “launching the natural pump for pumping and exhausting” to the State Intellectual Property Office.

Cui Xun said that the "engine pumping and exhausting natural pump" is also called "dual-powered engine". It is developed by using the principle that the first energy loss of the engine produces secondary exhaust gas. The same car is assembled separately. Under the same conditions, the fuel consumption of the dual-powered engine is only 30%.

The study of "impossible" as "possible" stems from an accidental trip by Cui Xun.

Once, the young Cui Xun went out to take a small individual bus, and when the driver came to refuel, he complained that “the oil price is too high” and “buy the car and can’t afford the oil”. After he heard it, he was very touched. He thought: If I can get the poor people in the world to buy a car, add a small amount of oil to drive the same mileage. Occasionally, the whimsy really made Cui Xun "the night can't be smashed". He wondered why he did not take the "automobile engine" for the first time to successfully produce the exhaust gas, and reasonably recovered the replacement of the original fuel oil. Isn't it possible to walk more with less fuel?

In order to turn this "whispering" into reality, Cui Xun bid farewell to the new job he just took when he was 24 years old. With his dream, he returned to the cold room and closed the door to develop the "engine pumping and exhausting natural pump."

Since 1995, Cui Xun has gradually achieved gratifying new harvests in the journey of development. He has successively obtained the "Automobile Engine Power Controller" issued by the National Patent Office, "Accelerated Controllers for Hydraulic Vehicle Internal Combustion Engines" and "Accelerated Control of Motor Vehicle Internal Combustion Engines". "Three utility model patent certificates." Since then, he has begun to have his own microwave income, not relying on his parents to help research.

At the age of 27, Cui Xun spent 8,000 yuan to buy a dilapidated old-fashioned jeep, preparing for his in-depth study of the "engine pumping and exhausting natural pump". The car was bought back, the fuel consumption was very high, and the individual driver’s “buy the car and can’t afford the oil!” The final stage of the development of the “engine exhaust pump natural pump” was to be in various types of transportation. On the tools, such as cars, trains, and ships, the experiment is carried out to obtain relevant parameters, and each time the machine is disassembled, the process is very troublesome, and the hands are greasy. After each installation, it is not necessary to open the machine repeatedly. For a long time, the fuel consumption of the car is getting bigger and bigger, and the wear of the car is also very serious. For the goal of tomorrow, Cui Xun is hitting the south wall and does not look back.

After each test, the drawings should be continuously improved. Since the processing of machine parts from new processing is not batch processing, it is difficult to find a partner, and after finding the cost and expensive, Cui Xun has taken all the savings for this purpose. There is really a lack of trial funding, and Cui Xun has bowed his head and went to work for a while. After the trial funds are sufficient, they will come back to trial production. What he thinks every day is success. One of his words to comfort his parents is that "the more times you fail, the more likely you are to be close to success."

On September 3, 2004, Cui Xun held a press conference at Beijing Friendship Hotel and officially introduced his invention to the public. This day, for Cui Xun, is another milestone in turning his dream into reality.

In the future, there are still countless difficulties in meeting Cui Xun. However, he has already "excluded all odds" and has not lacked the courage to go.
