Automobile pure oxygen combustion engine system

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...

AI Technical Summary

Problems solved by technology

EGR systems are known to reduce NOx emissions, but high EGR means intake air dilution and O 2 Reduced concentration will lead to worsening of combustion, resulting in decreased performance of diesel engine and increased soot level

Theoretically, pure oxygen intake can reduce soot emission, but pure oxygen intake will lead to O 2 The concentration increases, the combustion is sharp and full, which will lead to excessive combustion temperature, NO X Negative factors such as increased emission levels, excessive ablation of fuel injectors and combustion chambers, high pressure rise rates, and excessive combustion noise cannot guarantee smooth and reliable engine operation, so pure oxygen intake has not been able to operate in the engine use on
