【Abstract】 The in-cylinder purifying technology is to optimize the whole combustion process anew, that means to optimize and match combustion chamber, intake air flow and fuel supply system. On the base of test study on turbo-charging technology, intake air swirl increasing and round opening-shrunk combustion chamber, we began to do single factor changed once experiments on fuel supply system which had more important effect to emissions of diesel engine. The effects of changes in all parameters of fuel supply system to emission performances of turbo-charged diesel engine were tested practically, the affection regularities to four kinds of emissions were analyzed emphatically about fuel supply advance angle, nozzle diameter of injectors, construction and plug diameter of injection pump, then, rational match plan was proposed.更多还原
