Title:
DIESEL ENGINE DUAL-FUEL SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/096014
Kind Code:
A1
Abstract:
A diesel engine dual-fuel system, comprising: an emulsified oil tank (2) provided internally with a stirring device (3) and configured to store and stir emulsified oil; an emulsified oil supply pump (5) configured to provide power for the supply of the emulsified oil in the emulsified oil tank (2) to a diesel engine (1); an oil supply three-way valve (7) respectively communicated with a diesel tank (9), the diesel engine (1) and the oil supply pump (5); and an oil return three-way valve (8) respectively communicated with the diesel tank (9), the diesel engine (1) and the emulsified oil tank (2). Diesel oil or emulsified oil is selectively supplied to the diesel engine (1) by means of the oil supply three-way valve (7) according to the condition of the diesel engine (1). By means of the oil return three-way valve (8), return oil is selectively controlled to return to the diesel tank (9) or the emulsified oil tank (2), and the emulsified oil of the diesel engine (1) is prevented from returning to the diesel tank (9). According to the diesel engine dual-fuel system, the emulsified oil and the diesel oil can be converted in real time; the emulsified oil of the diesel engine (1) can be prevented from returning to the diesel tank (9), and the system is simple in structure. Also provided is a method for operating the diesel engine dual-fuel system.
