Abstract
The present invention relates to a method for adapting engine control of a gas engine in a vehicle. The method comprises determining, during operation of the gas engine, the specific gas constant of a fuel gas for the gas engine. The method further comprises determining the stoichiometric air fuel ratio of the fuel gas for the gas engine. The control of the gas engine is adapted based on the determined specific gas constant and the determined stoichiometric air fuel ratio. The present invention also relates to a system for adapting engine control of a gas engine in a vehicle, to a vehicle, and to a computer program product.
Claims21
A method for adapting engine control of a gas engine in a vehicle, the method comprising:
- determining, during operation of the gas engine, a specific gas constant of a fuel gas for the gas engine;
- determining a stoichiometric air fuel ratio of the fuel gas for the gas engine;
- and
- adapting a control of the gas engine based on the determined specific gas constant and the determined stoichiometric air fuel ratio.
A system for adapting engine control of a gas engine in a vehicle, the system comprising:
- means for determining, during operation of the gas engine, a specific gas constant of a fuel gas for the gas engine;
- means for determining a stoichiometric air fuel ratio of the fuel gas for the gas engine;
- and
- means for adapting a control of the gas engine based on the determined specific gas constant and the determined stoichiometric air fuel ratio.
A vehicle, comprising a system for adapting engine control of a gas engine in a vehicle, the system comprising:
- means for determining, during operation of the gas engine, a specific gas constant of a fuel gas for the gas engine;
- means for determining a stoichiometric air fuel ratio of the fuel gas for the gas engine;
- and
- means for adapting a control of the gas engine based on the determined specific gas constant and the determined stoichiometric air fuel ratio.
A computer program product stored on a non-transitory computer-readable medium, said computer program product for adapting engine control of a gas engine in a vehicle, wherein said computer program product comprises computer instructions to cause said at least one control unit to perform the following operations:
- determining, during operation of the gas engine, a specific gas constant of a fuel gas for the gas engine;
- determining a stoichiometric air fuel ratio of the fuel gas for the gas engine;
- and
- adapting a control of the gas engine based on the determined specific gas constant and the determined stoichiometric air fuel ratio.
