Automobile power reducer

Abstract

The invention discloses an automobile power reducer. The automobile power reducer is formed by a shell, an air inlet device, an impeller, a motor and a control device. The automobile power reducer disclosed by the invention has the beneficial effects that 1, the problems that when an automobile runs while an air conditioner is switched on, the power is insufficient, and the fuel consumption is increased are solved; 2, the energy utilization is maximized; 3, the automobile power reducer is easily popularized. Since the automobile power reducer has the characteristics that the manufacturing cost is low, the durability is high, undamaged installation is realized, the additional maintenance is not needed, the application range is wide, and the like, the automobile power reducer is easily accepted by broad masses, and the automobile power reducer is a necessary practical matching product of the automobile.

Description

technical field [0001] The invention belongs to the field of automobile devices, in particular to an automobile power reducer. Background technique [0002] At present, the number of cars in our country is increasing, and the number is still increasing every year. The atmospheric environment is becoming increasingly severe. The country vigorously calls and advocates the use of small-displacement cars, energy saving and emission reduction, and low-carbon driving. Taking the current traditional automobile as an example, in order to achieve energy saving and emission reduction, two problems must be solved: [0003] 1. Improve the efficiency of the internal combustion engine. [0004] 2. Reduce the loss of the output power of the internal combustion engine. [0005] However, as far as the current development of the automobile market is concerned, similar problems can only be solved simply by equipping automobile engines with superchargers, but the actual situation shows that s...

AI Technical Summary

Problems solved by technology

[0008] 1) short life

Because it must be assembled at the front end of the exhaust pipe to obtain exhaust gas as a power source to drive the turbine to rotate, the high-temperature exhaust gas as high as nearly 1,000 degrees will burn the turbine red and purple, and its service life will be greatly affected by the harsh environment. Shorten (normal lifespan no more than two years)

[0009] 2) Expensive

In order to ensure its service life, the materials used in the production of turbochargers must be made of special raw materials and complicated processing procedures, which makes it expensive

[0010] 3) High maintenance cost

The turbine under high temperature needs special lubrication and cooling system support, so it will increase its maintenance and other costs. Due to its harsh working environment, the exhaust gas turbocharger under correct use is also prone to failure, and the replacement parts cost high cost

[0011] 4) The practicability is not high

The exhaust gas turbine uses the exhaust gas produced by the engine itself as the driving source. The exhaust gas must reach a certain amount before the turbine can be driven to rotate. Generally, the supercharging effect can only be achieved when the engine speed reaches 2000 rpm or higher. When driving at low speed will not achieve the supercharging effect

[0012] 5) Large changes in installation

For various reasons (the original car was not equipped with a turbo design, etc.), it is necessary to install a turbocharger after purchasing the car for use. For such cases, since the original car is not equipped with a turbo design, it is necessary to cut the front section of the exhaust pipe to take the exhaust gas. , adding cooling and lubrication systems, etc., the changes are large and time-consuming

[0013] Based on the above reasons, even in terms of exhaust gas turbocharging with the highest degree of equipment in the original car, the recognition and popularity of the masses are not high.

[0014] 2. The traditional supercharger needs to be specially designed and matched with special vehicles, and the manufacturing cost is quite high. Currently, only a small number of high-end imported vehicles are used, and it is not easy to popularize the market.

Its disadvantages cannot be ignored. The life of the high-speed motor is extremely short, and it cannot be guaranteed to be used normally for a long time.

Moreover, the high-speed motor will make a high-frequency harsh sound, which is unacceptable

In addition to the particularity of high-speed motors, the cost is not low, and currently no car manufacturers have used them

[0016] 2. Most of the current cars are equipped with an air-conditioning system. Driving with an air-conditioning system does make people feel comfortable, but it also wastes a lot of fuel and affects the proper power of the car, increasing the loss of engine output power.

[0017] Traditional cars have not been equipped with equipment and methods that can solve the problem of insufficient driving power and increased fuel consumption when the air conditioner is turned on
