Abstract

The invention relates to an automobile pure oxygen combustion engine system which comprises an internal combustion engine and a gas recirculation system, and adopts a high pressure oxygen storage tank or a membrane separation oxygenerator to form a pure oxygen gas supply system for providing the pure oxygen; EGR waste gas of a vehicle EGR system is mixed with the pure oxygen, and then the mixed gas is taken as the inlet gas of the engine, so that engine oxygen-enriched combustion can be realized; while the emission of granules in a diesel engine is reduced, the discharge of nitrogen oxide of the diesel engine can be effectively reduced, thus reaching the strict discharge standard; furthermore, automatic closed-loop control can be carried out by using the ECU, and the oxygen content can be accurately controlled, thus controlling the combustion process of the engine and realizing ultra-low emission.

Description

technical field

[0001] The invention belongs to the field of internal combustion engines, in particular to a vehicle pure oxygen combustion engine system. Background technique

[0002] At present, environmental pollution is becoming a social issue of public concern, and diesel engine emission regulations formulated by various countries are becoming stricter year by year. Diesel engine harmful emissions are mainly NO X And fine particles (soot and soluble organic matter), due to their conflicting and contradictory purification methods. This makes it difficult to fully meet emissions regulations. Engine researchers have adopted various technologies, such as direct injection supercharging, intercooling, high-pressure injection, exhaust gas recirculation (EGR), electronic control, low lubricating oil consumption, etc., which have brought certain benefits to reduce emission levels , but fundamentally solving the above problems is still a technical problem. EGR systems are kno...
