Abstract:
A fuel supply system for a dimethyl ether engine, wherein dimethyl ether is supplied from a fuel tank to a high-pressure fuel pump whilst being raised to a saturated vapour pressure or above by means of a pressure feed pump and is then raised to a pressure suitable for injecting into an engine by means of the high-pressure fuel pump and supplied to a common rail to which fuel injection devices are connected, comprising:a dimethyl ether detecting device, disposed in a fuel pipe leading to said high-pressure fuel pump, for detecting the state of the dimethyl ether from the pressure feed pump; and an electronic control unit, connected to said dimethyl ether detecting device, for driving said high-pressure fuel pump when the dimethyl ether inside the fuel pipe leading to said high-pressure fuel pump is in a liquid state.
