FUEL SYSTEM FOR MULTI-FUEL ENGINE

摘要

A fuel system and a method of operation of the fuel system are described in the context of a multi-fuel internal combustion engine. As a non-limiting example, the method includes: varying a composition of fuel supplied to an inlet of a fuel pump responsive to engine output; operating the fuel pump to provide pressurized fuel at an outlet of the fuel pump using the fuel received at the inlet of the fuel pump; supplying the pressurized fuel from the outlet of the fuel pump to the internal combustion engine and to a fuel separator; and varying a proportion of the pressurized fuel supplied to the internal combustion engine relative to the fuel separator responsive to the engine output.
