Research Status and Development Trend of Dimethyl Ether Fuel Supply System

Article Preview

Abstract:

A survey of study on dimethyl ether engine fuel supply system at home and abroad was described, including pump-pipe-nozzle system and common-rail fuel supply system. The main trouble of practical application of dimethyl ether engine is wear and leakage problems in the fuel delivery system caused by low viscosity of dimethyl ether. For controllable premixed combustion of dimethyl ether engine, a fuel injection system is developed which is consisted of a diaphragm pump and a wear self-compensation nozzle or an independent lubrication nozzle. The system is expected to solve the above problems essentially and becomes a development direction for the future.
