What is the working principle of the nitrogen acceleration system added to the modified sports car?

The working principle of NOS (nitrogen acceleration system) is to form a high-pressure liquid and put it into the engine cylinder after forming a high-pressure liquid. Then, nitrogen will be mixed with air to burn, acting as a combustion aid in the engine to help the fuel burn.

The working principle of NOS (nitrogen acceleration system) is to form a high-pressure liquid state of nitrous oxide and put it into a steel cylinder, and then mix combustion with fuel as a combustion agent with air in the engine.

The working principle of nitrogen accelerator: 1. The so-called nitrogen accelerator does exist, but nitrogen cannot be accelerated. It should be a substance called N2O. The major is nitrogen oxygen pressurization. Nitrogen oxygen pressurization is the so-called NOS, which is the abbreviation of "nitro-oxygen system".

Nitrogen injection acceleration is the principle: the nitrogen acceleration system is (NOS) a product developed by HOLLEY in the United States.

It is said to be nitrogen, but it is not nitrogen at all! Nitrogen is N2, and the bottle is filled with liquid N2O, that is, laughing gas, or written as NOS. Of course, there is a brand of nitrogen manufacturer that is also NOS. The main function of that thing is to act as an oxidizing agent, which is equivalent to the liquid oxygen in the rocket.

The principle of nitrogen acceleration is as follows: In fact, nitrogen dioxide (N2O) is not used to accelerate the car engine;Its principle is to fill the nitrogen dioxide in the vehicle cylinder into the working cylinder to increase the oxygen content in the engine intake. At the same time, the fuel injection volume of the oil supply system should be increased.

How to set up the cornering system of Lego sports car

First, Lego, McLaren, turning system steering Steering wheel, make sure that the Lego sports car is not assembled incorrectly, and check whether the wheels and steering devices have been assembled correctly.Secondly, adjust the position of the wheels to ensure that the distance between the two front wheels of the car is the same and that each wheel can rotate smoothly.

Turn the steering wheel. According to the official website of Lego, Lego racing cars can turn the car by turning the steering wheel. When the transmission axis moves to one side, the wheels on the other side will move in the other direction, so as to realize the operation of steering.

To control the Lego Lamborghini remote control car Maverick to turn, you can follow the following steps: First, make sure that the Maverick and the remote control are fully charged. The battery used by the remote control is generally a 9V battery. Turn on the remote control and set the channel to the channel used by Maverick.

The steering wheel control ability can be turned at the end of the car before assembly with Le High-tech. The method is as follows. It is the use of turntable parts. The turntable parts are divided into upper and lower parts, and one part is fixed on the upper part of the turntable parts.

There are many ways to turn. You can look at the official drawings first. The simplest is a parallelogram structure.

How is the quality of the sports car

1. OK. The Horian sports car Little Ninja single-cylinder 250 is a motorcycle with a sporty appearance. Its whole vehicle structure and parts are of relatively good quality materials. The body is made of aluminum alloy, which is light and durable, the frame is stable and strong, and the suspension system is also excellent, which can provide good handling and driving stability. .

2. McLaren's quality is good, and the quality of the sports car level must be excellent. McLaren was born in the United Kingdom in 1963. It is a supercar brand based on F1 and supplemented by road sports cars.McLaren's logo is McLaren.

3. The overall quality of Kia Smart Run is good. The car is equipped with a number of high-tech configurations such as the uphill and down hill assistance system, which realizes the intelligentization of the whole vehicle. The forward air grille of Kia Smart Run adopts a five-spoke design and the size is also reduced, so that the lines at the bottom of the grille and the lines at the bottom of the headlights are connected. Yazhi Run will look back with electronic anti-glare.

4. The workmanship, quality and safety of European sports cars are not to mentioned, such as Ferrari, Lamborghini, Porsche, Koenisseck. However, the workmanship, quality and safety of Japanese sports cars are very poor. For example, GTR, it is said that a GTR in China exploded after a crash. Take a look at the interior of GTR again. It is very ordinary, cheap and plastic.

5. Good quality.The Kia Lion sports car is made of high-strength steel, which has excellent bearing capacity and impact resistance. The body coating adopts high-quality spraying technology, which is wear-resistant and can effectively prevent the body from rusting. The effect is good.

6. Although the mass is lighter than that of metal aluminum, and the final hardness is only the hardness of resin, its strength is higher than that of steel, and it is corrosion-resistant. Carbon fiber composite materials also have much higher resistance to tensile and bending than steel.
