Problems solved by technology

If the EFI device fails, such as damage to the oxygen sensor, control switch, and air supply valve, the three-way catalytic converter will soon be scrapped 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 the 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. Inside)
The three-way catalytic converter can only reduce the emission concentration of CO, HC, and NOX in the exhaust of motor vehicles, but it cannot achieve the purpose of completely eradicating the pollution of exhaust from motor vehicles.
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
Huge economic expenditures have affected consumer confidence and hindered the formation of a consumer market

Embodiment Construction

[0018] The integrated momentum exchanger is composed of 13 primary and secondary integrated exchange devices. 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. The primary and secondary exchangers integrated with momentum exchangers are connected in parallel to form a whole.

[0019] 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 the cost, 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.

[0020] The practical size of the integrated momentum exchanger can be...

Abstract

The present invention is one integrated moment exchanger for treating tail gas of motor vehicle. The integrated moment exchanger consists of 13 stages of main and auxiliary integrated exchangers connected parallelly, and each stage of exchanger has jetting reception tubes and diffusion tubes in the same number. The present invention can eliminate tail gas pollution radically, and may be used inreplacing available exhaust silencer system in motor vehicle.

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, regarding the prevention and control of air pollution caused by motor vehicle exhaust, the hydrogen-powered No. 1 prototype vehicle (a fuel cell vehicle powered by hydrogen) was released in 1998. The operating principle of the car is the reverse reaction of the water electrolysis reaction. Hydrogen (H2) and oxygen (O2) are mixed and reacted under controlled conditions to generate the only product: water and electricity, driving the car, and the maximum mileage can reach 400 km, with a top speed of 140 km / h. 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 price. In addition, the...
