Abstract
An aspect of the present disclosure provides a method for controlling a multi-fuel engine system configured use gas fuel and hydrogen, wherein maximum pressure and center of combustion of a cylinder may be detected while the multi-fuel engine system is operated, and a ratio of hydrogen to be mixed with gas fuel may be determined on the basis of the detected maximum pressure and center of combustion in the cylinder.
Claims15
A method for controlling a multi-fuel engine system configured to use gas fuel and hydrogen, the method comprising:
- detecting maximum pressure and center of combustion of a cylinder during operation of the multi-fuel engine system;
- and
- determining a proportion of hydrogen to be mixed with the gas fuel, based on the maximum pressure and the center of combustion, which are detected, of the cylinder.
A multi-fuel engine system comprising:
- a cylinder including a combustion chamber, an intake port communicating with the combustion chamber, and an exhaust port communicating with the combustion chamber;
- a gas inflow valve configured to inject at least one of gas fuel or a mixture of the gas fuel and hydrogen into the intake port;
- and
- a controller configured to determine a proportion of hydrogen to be mixed with the gas fuel, based on maximum pressure of the cylinder, and center of combustion of the cylinder.
