Fuel supply system for supplying a fuel emulsion to a fuel injection system of an engine

Abstract

A fuel supply system 12 of an internal combustion engine 14, in particular a marine diesel engine, for supplying a fuel emulsion to a fuel injection system 16 of the engine. The fuel supply system includes at least one blending unit 30 comprising a static mixer 31 and blends a primary fuel and a secondary fuel to provide a fuel emulsion prior to being supplied to the fuel injection system. The primary fuel may be fuel oil or diesel fuel and / or the secondary fuel may be at least one of methanol, ammonia, liquid natural gas, and hydrogen. The static mixer may comprise a turbulator arrangement, in particular at least two grids of joint metal bars. A buffer tube 32 for buffering a fuel medium may be installed upstream or downstream of the blending unit. A first blending unit (30a, figure 1b) may be installed upstream of the buffer tube and a second blending unit (30b, figure 1b) may be installed downstream of the buffer tube.
