Abstract
The present invention refers to a fuel supply system of an internal combustion engine, in particular of a marine diesel engine, for supplying a fuel emulsion to a fuel injection system of the engine. The fuel supply system includes at least one actuated blending unit configured to blend a primary fuel and a secondary fuel to provide the fuel emulsion prior to being supplied to the fuel injection system.
Claims13
A fuel supply system of an internal combustion engine for supplying a fuel emulsion to a fuel injection system of the engine, the fuel supply system comprising:
- a mixing tank;
- a first blending unit upstream of the mixing tank;
- a second blending unit downstream of the mixing tank;
- wherein the first blending unit comprises a first inlet configured to receive a primary fuel, a second inlet configured to receive a secondary fuel, and an outlet configured to direct the fuel emulsion generated by the first blending unit toward the mixing tank;
- and
- wherein the second blending unit comprises an inlet for receiving the fuel emulsion from the mixing tank and an outlet configured to direct the fuel emulsion after being processed in the second blending unit toward the fuel injection system of the engine.
A fuel supply system, of an internal combustion engine for supplying a fuel emulsion to a fuel injection system of the engine, including at least one actuated blending unit configured to blend a primary fuel and a secondary fuel to provide the fuel emulsion prior to being supplied to the fuel injection system, the fuel supply system further comprising at least one sensor unit configured to determine at least one physical or chemical characteristic of the fuel emulsion downstream of the at least one actuated blending unit and a control unit configured to control operation of the at least one actuated blending unit in dependence on the characteristic determined by the at least one sensor unit.
