A method for producing a fuel composition, including the following steps: providing special gas containing combustible substances; reforming a first part of the special gas by producing synthesis gas; producing dimethyl ether from the synthesis gas by producing a reaction mixture containing a dimethyl ether; separating methanol from the reaction mixture and producing a methanol-reduced dimethyl ether mixture; and bringing together a second part of the special gas with the methanol reduced dimethyl ether mixture in order to obtain the fuel composition.

A system for remotely monitoring and controlling operation of a hydro-diesel engine, having: (a) a diesel engine assembly; (b) a hydro-diesel assembly connected to the diesel engine assembly; (c) a remote control system; and (d) a remote computer system in communication with the remote control system, wherein the remote computer system is configured to instruct the remote control system to turn off operation of either: (i) the hydro-diesel assembly while permitting the diesel engine assembly to continue operation while the hydro-diesel assembly is not operating, or (ii) both the hydro-diesel assembly and the diesel engine assembly.

The invention proposes a method and an emulsifying apparatus for the operation of a diesel engine with a water-diesel fuel emulsion, wherein the water fraction is varied as a function of the engine operating point and/or the emulsifying apparatus and/or parts of the injection line are flushed with pure diesel fuel upon a shutdown of the engine.

An ethanol engine system stabilizes components of reformed gas generated by a reformer and a calorific value of fuel supplied to an engine. The ethanol engine system includes a reservoir tank for an aqueous ethanol solution, a first supply device that supplies the aqueous ethanol solution to the reformer, a separator that cools mixed gas fed from the reformer, including the reformed gas, condenses water vapor included in the mixed gas and separates into gas and liquid, a reformed gas supply device that supplies the reformed gas separated by the separator to the engine, a recovery tank that collects a recovery solution separated by the separator, and a first recovery solution supply device that supplies the recovery solution in the recovery tank to the reformer or a second recovery solution supply device that supplies the recovery solution in the recovery tank to a combustion chamber of the engine.

A method of conditioning a particle filter provided for receiving exhaust gases from internal combustion engine is provided and includes providing a first engine control mode and a second engine control mode, wherein in the second engine control mode at least one combustion control parameter that affects the characteristics of particles emitted together with and carried by the exhaust gases from the engine is different in relation to the first control mode such that the filling rate of the particle filter with particles is increased compared to the filling rate that would have been achieved with the first engine control mode, determining a soot loading status of the particle filter, and temporarily applying the second engine control mode to the engine based on the soot loading status.

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.
