Abstract

The invention discloses an automobile secondary air pump driven by exhaust. The automobile secondary air pump comprises a pump body, a driving impeller, a transmission shaft, an air inlet impeller and an air inlet pipeline, wherein one side of the pump body is provided with a driving cavity, and the other side of the pump body is provided with an air inlet chamber; the front and rear ends of the driving cavity are provided with connectors connected with an exhaust pipeline; the driving impeller is arranged in the driving cavity by virtue of the transmission shaft, and the other end of the transmission shaft extends into the air inlet chamber; the air inlet impeller is arranged at the other end of the transmission shaft; the air inlet pipeline is connected with the air outlet of the air inlet chamber, and the other end of the air inlet pipeline is provided with a connector connected with the exhaust pipeline; the air pump is capable of driving the impeller to rotate by virtue of an exhaust driving force on a vent pipe of an automobile so as to realize an air blowing effect without using an automobile battery power supply, effectively reducing the use load of the automobile battery and improving the waste gas utilization ratio, and is relatively good in economical efficiency and energy conservation and quite good in use effect.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an automotive secondary air pump driven by exhaust gas. Background technique [0002] The secondary air pump is to send a large amount of air with low pressure through the hose to the diverter valve through the operation of the air pump when the engine is working. Normally, with the valve on the diverter valve open, air flows through the diverter valve and the check valve into the air injection manifold. Its function is: the air injection manifold injects air flow into the engine exhaust hole or exhaust manifold, reacts with hc and co in the exhaust, and further converts it into co2 and water vapor to reduce exhaust pollution. [0003] The secondary air pumps of automobiles in the prior art are all driven by motors, which need to consume the power of the battery on the car, and the loss of the battery is very large. If the driving force of the car can be used to drive the air...
