Abstract
A propulsion device for vehicles includes a device for the partial oxidation of fuel, a fuel tank and a diesel internal combustion engine. The device for the partial oxidation of fuel is in fluid connection with the fuel tank and the diesel internal combustion engine, with the result that at least some of the fuel carried in the vehicle is taken for partial oxidation before combustion in the diesel internal combustion engine. A method for operating such propulsion devices using partially oxidized fuel in the propulsion devices reduces soot emissions.
Claims24
A propulsion device for vehicles, comprising:
- a device for partial oxidation of fuel;
- a fuel tank for holding the fuel;
- and
- a diesel internal combustion engine, the device for partial oxidation being in fluid communication with the fuel tank and the diesel internal combustion engine, so that a first portion of the fuel is delivered to the device for partial oxidation, a second portion of the fuel bypasses the device for partial oxidation, and the first portion of the fuel is partially oxidized in the device for partial oxidation before combustion in the diesel internal combustion engine to produce a partially oxidized fuel having an oxygen content of at least 0.5% by weight and no more than 30% by weight.
A method for operating a diesel internal combustion engine, comprising the steps of:
- supplying a diesel fuel;
- partially oxidizing at least some of the diesel fuel to produce an oxidized portion of the diesel fuel;
- mixing the oxidized portion of the diesel fuel with unmodified diesel fuel in a mixer unit to produce a mixture;
- introducing the mixture into a combustion chamber of the diesel internal combustion engine;
- and
- carrying out a compression ignition combustion process with the mixture.
