Problems solved by technology

However, such cooling methods basically adopt the cross-flow heat exchange method, the heat exchange efficiency is not high, and the heat exchanger is too large, which not only occupies the limited space of the car, but also increases the operating load and production cost of the car.

Abstract

Disclosed are a device and a method for improving the work efficiency of an engine and reducing emission of harmful gas. The device comprises a vortex supercharger, the engine, a gas inlet manifold, an inter-cooler, a radiating fan and a radiating water tank II; the inter-cooler is a counter-current heat exchange type cooler, the counter-current heat exchange type cooler comprises fin structures and micro-channel or mini-channel structures which are alternately arranged, an outlet of a fin side of the counter-current heat exchange type cooler is connected with the gas inlet manifold by a pipeline, and an inlet of the fin side of the counter-current heat exchange type cooler is connected with the vortex supercharger by a pipeline; and the engine is respectively connected with a coolant inlet of the radiating water tank II and a coolant outlet of the inter-cooler by pipelines, and a coolant outlet of the radiating water tank II is connected with a coolant inlet of the inter-cooler by a pipeline. The invention further provides the method for improving the work efficiency of the engine and reducing the emission of the harmful gas. The device and the method have the advantages that the work efficiency of the engine can be improved by 10% at least, and the emission of the harmful gas NOX can be reduced by 24% at least.

Description

technical field [0001] The invention relates to a device and method for improving engine working efficiency and reducing harmful gas discharge, in particular to a device and method for improving engine working efficiency and reducing harmful gas discharge by using vortex supercharging. Background technique [0002] With the continuous growth of the number of automobiles and the rapid development of the economy, the consumption and depletion of fossil energy have been aggravated, and at the same time, serious pollution and damage have been brought to the environment. In recent years, smog has plagued large and medium-sized cities in my country. On the one hand, it is easy to cause vehicle traffic accidents, and on the other hand, it is easy to cause great harm to people's health. In addition, if the smog continues to spread, the time for crops to receive sunlight will be greatly shortened, which will affect the growth of crops and cause crop production to decrease. Studies h...
