Electric centrifugal-type air supplement device

Abstract

The invention relates to an electric centrifugal-type air supplement device which comprises an exhaust-gas turbo charger and an intercooling system, wherein the intercooling system is connected with an engine, a check value is arranged on an air outlet end of the exhaust-gas turbo charger, and a main shaft extension end of the exhaust-gas turbo charger is connected with the air supplement device through a clutch shaft. The electric centrifugal-type air supplement device not only can supplement air with high speed in the low-speed state, achieves the optimal combustion state, but also has simple manufacturing process and lower cost and can not influence the service life of a motor.

Description

technical field [0001] The invention relates to a vehicle air supply device, in particular to an electric centrifugal air supply device with accurate air supply and difficult gas backflow. Background technique [0002] Exhaust gas turbocharging technology is an important measure to improve vehicle performance. More and more vehicles have adopted this supercharging technology. On the one hand, it can improve fuel economy, and on the other hand, it can reduce exhaust pollution. However, when the vehicle is just started, there is almost no exhaust gas emission, and it can only rely on natural intake, while the exhaust gas turbocharger is driven by the exhaust gas to rotate the turbine to cause the compressor to work, so the compressor cannot work normally, thus As a result, due to the insufficient air intake of the vehicle engine, the fuel cannot be fully burned and black smoke is emitted, which is not only a serious pollution to the ambient air quality, but also causes a certa...

Problems solved by technology

However, when the vehicle is just started, there is almost no exhaust gas emission, and it can only rely on natural intake, while the exhaust gas turbocharger is driven by the exhaust gas to rotate the turbine to cause the compressor to work, so the compressor cannot work normally, thus As a result, due to insufficient air intake of the vehicle engine, the fuel cannot be fully burned and black smoke is emitted, which is not only a serious pollution to the ambient air quality, but also causes a certain waste of fuel

[0003] At present, the solutions to this phenomenon on the market are: 1) Use high-quality fuel oil with ultra-low sulfur content, but the quality of fuel oil supplied in China is difficult to meet the standard; 2) Add a fuel limiting device in the fuel pump to prevent Slow down the fuel supply speed during acceleration to match the air, but this will prolong the acceleration time; 3) Add an air supply device between the air filter and the turbocharger, but the smoke suppression effect is not very good Ideal, and fuel consumption will go up
