Abstract

The invention provides an engine waste gas energy utilization device with a compact structure and high energy utilization rate and an automobile using the same. The device comprises a hollow shell with an air inlet and an air outlet, wherein a catalytic carrier of a three-way catalytic converter and a thermoelectric conversion element are arranged along the flowing direction of waste gas in the shell in turn; and a temperature difference generation device to be communicated with the cooling pipe of the automobile is arranged at the position close to the thermoelectric conversion element on the shell. The structure of the automobile using the engine waste gas energy utilization device is as follows: the waste gas outlet of the engine of the automobile is communicated with the air inlet of the shell of the engine waste gas energy utilization device; the air inlet of the muffler of the automobile is communicated with the air outlet of the shell of the engine waste gas energy utilization device; the cooling system of the automobile is communicated with the temperature difference generation device to form closed-loop circulation; and the electrodes of the storage battery of the automobile are connected with the electrode of the thermoelectric conversion element. The engine waste gas energy utilization device has a simple and compact structure and can utilize the waste gas for generating power and reduce oil consumption.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacture, and in particular relates to a device for utilizing exhaust gas energy of an engine and an automobile using the device. Background technique [0002] With the depletion of oil resources, the price of oil continues to rise, and the public's awareness of environmental protection is gradually increasing. Therefore, a new generation of engines with high performance, low fuel consumption, and low emissions has become the research and development goal of many automobile manufacturers. In addition to reducing the fuel consumption of motor vehicles, making full use of the heat energy emitted by fuel combustion has become an important means to reduce the fuel consumption of motor vehicles. For example, as disclosed in the patent "exhaust heat recovery power generation device and automobile equipped with the power generation device" (patent application number: CN200580012118.5) and "internal...
