Abstract

The invention discloses an oxygen-enriched combustion engine system and belongs to the field of energy conservation and emission reduction of engines. The system comprises an oxygen supply device, an oxygen nozzle, a cylinder head, a distribution machine and a chain wheel cover, wherein high-concentration oxygen is directly jetted into an engine combustor through the oxygen nozzle, the cylinder head contains the oxygen nozzle, and the distribution machine controls timing work of the oxygen nozzle; the oxygen supply device is driven by an engine crankshaft through a belt wheel mechanism and controlled by an electromagnetic valve to be reversed, a first adsorption tower and a second adsorption tower work alternately, and therefore low-pressure oxygen is generated continuously; the oxygen is cached in an air storage tank, pressurized through a booster pump to reach the pressure higher than the maximum pressure in an engine cylinder, and finally jetted into the combustor through the oxygen nozzle; the distribution machine controls intake and exhaust distribution of the engine and also controls timing opening and closing of the oxygen nozzle through a cylindrical cam mechanism. The oxygen-enriched combustion engine system is low in cost, and can greatly improve engine power, reduce fuel consumption, reduce emission of a part of harmful gas of the engine, improve coldstart performance of the engine and increase the response speed of the engine.

Description

technical field [0001] The invention relates to an oxygen-enriched combustion engine system, in particular to an oxygen-enriched combustion engine which uses an oxygen nozzle to directly inject oxygen into a cylinder, and an oxygen supply system which utilizes the principle of pressure swing adsorption to produce oxygen, and belongs to the field of engine energy saving and emission reduction. Background technique [0002] The advent of the internal combustion engine has greatly changed the way of human existence and promoted the rapid development of society. After more than 100 years of research and development, internal combustion engine technology has become increasingly mature. Compared with its initial appearance, both power performance and economic benefits have been comprehensively improved, but it is difficult to take into account power performance, economic benefits and exhaust emissions at the same time. requirements. The early engines mainly focused on the power p...
