Fuel treasure's main function is not to save fuel.
Everyone must have had the experience of being promoted as fuel treasure by gas station staff. In their words, the fuel consumption will drop a lot after adding fuel treasure, and the oil money saved is more valuable than buying fuel treasure! In fact, this statement is incorrect. Fuel treasure's biggest role is not to save fuel, but to clean up the engine carbon deposit. If there is a fuel-saving effect, it is also carbon deposition that reduces fuel consumption, but this fuel consumption can be basically ignored.
Traffic lights were invented because of women's clothes.
The origin of traffic lights can be traced back to1England in the early 9th century. At that time, the woman in red said she was married, while the woman in green said she was unmarried. So inspired by this kind of clothing, a British mechanical designer named Hart designed red and green traffic lights, but at that time it was kerosene lamps. It was not until the 20th century that electronic traffic lights appeared, and then traffic lights were widely promoted around the world.
Most of the car special effects in movies are fake.
Friends who have seen The Fast and the Furious know that Boss Tang and Brian in the play travel around the world in various performance cars, and there are often scenes of flying cars and gun battles, which make the fans enjoy themselves. In fact, the average car can't afford to fly like that in the movie, and it will be torn apart by the strong ground impact when landing. It is basically impossible to use the car door as a bunker and a bullet, because the general car door is only made of a few extremely thin pieces of leather, and even a small caliber pistol can easily penetrate.
Lamborghini tractor
Nowadays, Mercedes-Benz and Lamborghini have developed into household car brands, but people don't know much about them. Everyone should know that Lamborghini started from tractors, but why must it go from manufacturing tractors to producing sports cars? It is said that the founder of Lamborghini, Felucio Lamborghini, went to buy a Ferrari, but Enzo, the founder of Ferrari, sarcastically said that he was just a tractor manufacturer and was not worthy to drive his Ferrari. After losing his temper, Felucio Lamborghini was determined to build a car that surpassed Ferrari. It was precisely because of this old man's "anger" that today's Lamborghini came into being!
Mercedes tricycle
Everyone knows that Mercedes-Benz is the originator of making cars, but few people know that its first "car" is actually a tricycle. 1886, Karl Benz trial-produced a single-cylinder four-stroke gasoline engine, which was installed on the frame of a tricycle composed of steel pipes and wooden boards. It uses steel rim and solid rubber tire, and drives the gear by turning the handle to complete steering. The engine drives the rear wheel through the transmission belt mechanism and chain, and the speed can reach 15 km/h, 65,4381October 29th. Ben Ci applied for the patent of this car to the German Patent Office, so this Mercedes-Benz tricycle became recognized as "the first car in the world".
Editor's summary: In addition to the cold knowledge of these car circles, there are many things. For example, Audi A6 is the car with the highest vibration rate, and the first car driver in history was a female driver.
