INTERNAL COMBUSTION ENGINE AND METHOD TO INCREASE THE TEMPERATURE OF A LIQUID IN THE INTERNAL COMBUSTION ENGINE

A method, controller, and internal combustion engine including the controller and operable in accordance with the method by: determining a temperature of a working liquid in an engine block circuit () of the internal combustion engine (), the working liquid comprising a cooling liquid or a lubrication liquid; operating the internal combustion engine (); engaging a thermal load responsive to the temperature of the liquid being below a first temperature threshold, wherein engaging the thermal load comprises at least one of increasing a pumping load of the internal combustion engine (), or changing an air/fuel ratio, thereby adding heat to the engine block circuit (); controlling the thermal load as a function of the temperature of the liquid; and disengaging at least a portion of the thermal load responsive to the temperature of the liquid being above the low temperature limit.
