Abstract

The invention relates to a device for plateau oxygen-enrichment axillary combustion of an engine. The device comprises a pressure control module and a gas treating module, wherein the pressure control module comprises a fan and a gas ring vacuum pump, the gas treating module comprises an air filter, a spiral-wound membrane separator and a buffer tank, the output end of the fan is connected with the inlet of the air filter, the outlet of the air filter is connected with the inlet of the spiral-wound membrane separator, the spiral-wound membrane separator is provided with a nitrogen-enrichment outlet and an oxygen-enrichment outlet, the oxygen-enrichment outlet of the spiral-wound membrane separator is connected with the input end of the gas ring vacuum pump, the output end of the gas ring vacuum pump is connected with the inlet of the buffer tank, and the outlet of the buffer tank is connected with a gas inlet system of the engine. According to the device, the oxygen content in inlet gas of the engine is increased, and therefore the dynamic property and the economy of the engine are increased.

Description

technical field [0001] The invention relates to an accessory device of an engine, in particular to a device for an engine's plateau oxygen-enriched auxiliary combustion. Background technique [0002] At present, when automobiles, construction machinery and other power equipment work on plateaus, due to low air pressure, engine charging efficiency decreases, and fuel combustion is incomplete, resulting in a significant decline in equipment performance, specifically manifested in: reduced power and torque, increased fuel consumption and increased emissions. Seriously affect the working efficiency of power equipment. Power equipment specially used for plateau use, such as plateau type vehicles, usually adopts the method of engine intake boosting to improve the power and economy of the engine. However, when ordinary power equipment works on a plateau, the problem of power and economical decline is unavoidable. Oxygen-enriched combustion technology is used in the market to impr...
