Problems solved by technology

EGR is 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

Embodiment Construction

[0015] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0016] An internal combustion engine pure oxygen intake oxygen-enriched combustion control method, using part of the recirculated exhaust gas as a part of the intake air of the internal combustion engine, and its innovation is: using pure oxygen as the remaining part of the intake air of the internal combustion engine , the specific steps are: using a pure oxygen supply source to provide pure oxygen, and the pure oxygen supply source is a polymer oxygen separation device or a pure oxygen storage device. Adjust the pure oxygen flow through the regulating valve. Pass pure oxygen into the pressure-stabilizing mixing tank to fully mix with the recirculated exhaust gas after pressure stabilization, flow adjustment and cooling, and then pass into ...

Abstract

The invention relates to a method and a system for controlling pure oxygen air input oxygen-rich combustion of an explosive motor, which adopt recirculation waste gas as part of the total air input of the explosive motor and adopt pure oxygen as the remaining part of the total air input of the explosive motor to achieve the combination of high waste gas recirculation and pure oxygen air input and the oxygen-rich combustion, so that the advantages of the modes are complementary with each other to achieve the aim of controlling the exhausts of NoX, CO, HC and PM of a diesel engine, and simultaneously ensure that the combustion in an engine cylinder is smooth and controllable, improve the power output of the explosive motor and reduce the fuel consumption.

Description

technical field [0001] The invention belongs to the field of internal combustion engines, in particular to a control method and a control system for pure oxygen intake oxygen-enriched combustion of an internal combustion engine. 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 sol...
