Abstract
Method of supplying a spark-ignition internal combustion engine is provided. The method includes a mixing procedure, on board the vehicle, of methane and hydrogen and in which a ratio between methane and hydrogen is determined at least as a function of a methane quality. A spark ignition internal combustion engine includes at least one cylinder having an intake manifold and at least one methane and hydrogen injection device.
Claims8
A fuelling method of a spark-ignition internal combustion engine comprising:
- performing a preliminary methane quality analysis procedure, wherein the preliminary methane quality analysis procedure comprises varying fuel supply parameters of the spark-ignition internal combustion engine, analyzing a gaseous species contained in exhaust gases produced as a result of the varying of the fuel supply parameters, and obtaining a methane quality;
- mixing, on board a vehicle, methane and hydrogen according to the obtained methane quality;
- and
- iterating the performing of the preliminary methane quality analysis procedure and the mixing of methane and hydrogen to generate a mixture of methane and hydrogen based on dynamic methane quality.
A spark ignition internal combustion engine comprising at least one cylinder having an intake manifold and at least one methane and hydrogen injection device operatively connected with the intake manifold and a processing unit configured to:
- perform a preliminary methane quality analysis procedure, wherein the preliminary methane quality analysis procedure comprises varying fuel supply parameters of the spark-ignition internal combustion engine, analyze a gaseous species contained in exhaust gases produced as a result of the varying of the fuel supply parameters, and obtain a methane quality;
- mix, on board a vehicle, methane and hydrogen according to the obtained methane quality;
- and
- iterate the performing of the preliminary methane quality analysis procedure and the mixing of methane and hydrogen to generate a mixture of methane and hydrogen based on dynamic methane quality.
