Vehicle turbocharging device

Abstract

The invention relates to a vehicle turbocharging device. The vehicle turbocharging device comprises an exhaust gas turbocharger as well as an electric device for driving the exhaust gas turbocharger to work normally when the exhaust gas turbocharger can not work normally because the vehicle initially starts and the exhaust gas air capacity is not sufficient. The main shaft of the exhaust gas turbocharger axially extends from a blower impeller end, passes through the bend tube wall of an air inlet pipe of the exhaust gas turbocharger from the inside to the outside and is coupled to the shaft of a drive motor through a clutch. By adopting the invention, the air can be supplemented at high speed at the state of low speed, the optimum combustion state can be achieved, the making process is simple, the service life of the motor is not affected and the cost is lower.

Description

technical field [0001] The invention relates to a turbocharger, in particular to a vehicle turbocharging device capable of driving the waste turbocharger to work normally when it fails to work normally. 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 ...

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
