Abstract:A novel system of diesel online emulsifying combustion based on AVR single-chip microcomputer auto-control was proposed. Diesel speed and load signals were sent into Electronic Control Unit (ECU), these real-time operating condition signals were analyzed and treated by the control center, and then based on the experimental results the opening time of electromagnetic valve was controlled to realize online water-injection adjusting and optimum water-fuel proportion. Without changing the structure parameters of diesel and adding any emulsifying agents, the system was tested in single cylinder diesel engine. Under the condition of 15% water proportion, the specific fuel consumption was reduced by 4.39%, and the emissions of NOx and particulate matters (PM) are reduced obviously.
