Abstract
The present invention pertains to a method for controlling operation of an internal combustion engine configured to run on a fuel mixture of hydrogen and natural gas. The method comprises a step of obtaining temperature values measured by at least one temperature sensor provided in a cylinder head of the engine; and a step of controlling operation of the engine in dependence on the temperature values.
Claims15
A method for controlling operation of an internal combustion engine configured to run on a fuel mixture of hydrogen and natural gas, the method comprising:
- obtaining temperature values measured by at least one temperature sensor provided in a cylinder head of the engine, the temperature values correspond to a composition of the fuel mixture, the fuel mixture is provided before entering a combustion chamber;
- determining a composition of the fuel mixture based on the obtained temperature values and a reference temperature, the composition indicative of a portion of hydrogen in the fuel mixture;
- and
- controlling operation of the engine based at least in part upon the composition of the fuel mixture.
An internal combustion engine configured to run on a fuel mixture of a natural gas and hydrogen, the internal combustion engine comprising:
- at least one temperature sensor provided in a cylinder head of the engine;
- and
- a control unit operatively connected to the at least one temperature sensor, the control unit—configured to:
- obtain temperature values measured by the temperature sensor, the temperature values correspond to a composition of the fuel mixture, the fuel mixture is provided before entering a combustion chamber;
- determine a composition of the fuel mixture based on the obtained temperature values and a reference temperature, the composition indicative of a portion of hydrogen in the fuel mixture;
- and
- control operation of the engine based at least in part upon the composition of the fuel mixture.
