Abstract

The invention aims at providing a control method for a hydrocarbon fuel ignition type zero-nitrogen emission engine with pure oxygen as oxidant. The technical scheme of combination of pure oxygen airinflow and exhaust gas recirculation and the strategy that the pure oxygen air inflow volume and the exhaust gas recirculation air inflow volume are collaborative along with work conditions are adopted, stable and controllable combustion in an engine cylinder is guaranteed, the power requirement is met, and meanwhile the purposes of zero NOx emission of the hydrocarbon fuel ignition type engine and reduction of emission of HC, CO and PM can be achieved.

Description

technical field [0001] The invention belongs to the field of engines, in particular to a hydrocarbon fuel ignition type zero-nitrogen emission engine using pure oxygen as an oxidant and a control method. Background technique [0002] With the increasing number of cars, carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM) emitted by cars are causing more and more serious pollution to the atmosphere. Environmental issues have become a social issue of public concern. At present, the emission regulations formulated by governments around the world are becoming stricter year by year. At the same time, measures such as restricting the operating areas of vehicles that do not meet emission standards have been implemented to alleviate serious urban pollution. Therefore, there is an urgent need for a technical path that can effectively reduce exhaust emissions. [0003] As we all know, the harmful emissions of hydrocarbon fuel ignition engines ar...
