Problems solved by technology

If the EFI device fails, such as the oxygen sensor, the control switch, and the air supply valve are damaged, the three-way catalytic converter will be scrapped quickly and lose its function
At the same time, the honeycomb structure of the three-way catalytic purifier is prone to clogging, reaches saturation, and loses its purification effect. It should be replaced with a new purifier frequently, thereby increasing the burden on consumers (generally, the normal use cycle is within 90 days. )
The three-way catalytic converter only serves to reduce CO, HC, and NO in motor vehicle exhaust X If the emission concentration is too high, the goal of completely eradicating motor vehicle exhaust pollution cannot be achieved by itself.
The disadvantages are: it affects the dynamic performance of motor vehicles, and it is dangerous when adding gas; the safety is reduced, the supporting and service facilities are not complete, and the scope of promotion is limited; the modification cost is high
But for nitrogen hydride (NO X ) governance effect is not perfect

Embodiment Construction

[0021] The integrated momentum exchanger consists of several stages of integrated exchangers. Except that the first-stage main exchanger is directly connected with the exhaust port of the motor vehicle engine, the other stages are fastened into a whole through the connecting channel by screw fastening.

[0022] The processing material of the integrated momentum exchanger is easy to obtain. It can be made of high-temperature-resistant and non-skinning stainless steel, or it can be made of corrosion-resistant aluminum alloy. In order to reduce costs, it can also be made of ordinary steel. The processing method can be completed by machine tool cutting and drilling machine drilling. In order to meet the needs of mass processing, it can also be obtained by precision die-casting.

[0023] The practical size of the integrated momentum exchanger can be determined according to the displacement of the engine, and it is suitable for large or small. Generally speaking, the outer dimensi...

Abstract

The invention provides a kind of integrate momentum exchanger for preventing the contamination of car tail gas. The character lies in: it is formed by connecting several grades of integral exchangers, each grade of exchanger is made up of receiving pipe, dispersing pipe and negative hole integrated on a mechanism processing flat with the same quantity, and there sets parallel fixed three pressure enhancing pipe of ejection receiving pipe between the first grade and the fourth grade, there sets three parallel pressure adjusting pipe of dispersant pipe between the seventh grade and the ninth grade, one end of the first grade exchanger connects with the air discharging outlet of the car engine, the other end is connected with the current adjusting device and the end tail gas discharging outlet; the invention can eliminate contamination entirely, it also can replace the current discharging and voice resisting system in car.

Description

Technical field [0001] The invention relates to a device for preventing and controlling air pollution, in particular to an integrated momentum exchanger for preventing and controlling motor vehicle tail gas pollution. Background technique [0002] In the prior art, and in order to prevent and control the air pollution caused by motor vehicle exhaust, in 1998, the hydrogen-powered No. 1 prototype vehicle (a fuel cell vehicle powered by hydrogen) was released. The operating principle of the car is the reverse reaction of water electrolysis reaction, through hydrogen (H 2 ) and oxygen (O 2 ) mixed and reacted under controlled conditions to generate the only product: water and electricity, driving the car with a maximum mileage of 400 kilometers and a maximum speed of 140 kilometers per hour. However, the popularization and application of the hydrogen-powered No. 1 fuel cell vehicle is full of difficulties, first of all, it is restricted by the transformation and high sales pr...
