Automobile tail gas generating set

Abstract

The invention discloses an automobile tail gas generating set which is arranged in an automobile exhaust pipe and is located at the end, far away from an engine, of a three-way catalyst converter. The automobile tail gas generating set is capable of conducting analytical processing on related information which is monitored by a monitor and can affect normal operation of a turbine generator through an ECU, and conducting control over an air inlet control valve of the turbine generator according to an analyzed result, and consequently controls on-off of tail gas in the turbine generator. On the basis that the utilization rate of automobile exhaust is improved, the automobile tail gas generating set can further ensure the normal use of the turbine generator in the automobile tail gas generating set.

Description

technical field [0001] The invention relates to the field of automobile tail gas recycling, in particular to an automobile tail gas power generation device. Background technique [0002] The energy of the exhaust gas discharged from the internal combustion engine accounts for about 25%-40% of the thermal efficiency of the engine, which, in addition to causing a large degree of waste, also pollutes the environment. In view of this problem, at present, for example, using this part of exhaust gas for turbocharging, but only about 10% can be utilized, and due to the hysteresis effect and complex structure of turbocharging, it is difficult to fully apply this technology. In addition, there have been similar technologies that use this part of the exhaust gas to drive the corresponding generator to generate electricity, but there is also the problem of low energy utilization; and because the flow and pressure of the exhaust gas change at any time with the vehicle condition, it is d...

Problems solved by technology

[0002] The energy of the exhaust gas discharged from the internal combustion engine accounts for about 25%-40% of the thermal efficiency of the engine. In addition to causing a large degree of waste, it will also pollute the environment.

In response to this problem, there are currently, for example, the use of this part of the exhaust gas for turbocharging, but only about 10% can be utilized, and due to the hysteresis effect of turbocharging and the complexity of the structure, it is difficult to fully apply this technology.

In addition, there have been similar technologies that use this part of the exhaust gas to drive the corresponding generator to generate electricity, but there is also the problem of low energy utilization; and because the flow and pressure of the exhaust gas change at any time with the vehicle condition, it is difficult to guarantee Exhaust gas can normally drive the generator to work at any time, often easily causing damage to the generator, etc.
