Abstract: A method for generating display data comprises detecting user input via an input interface. A processor is in communication with the input interface to generate display data comprising a display object for display by a display device. The display object is representative of an action that will subsequently be performed by the processor on continuation of the user input. The display data on the display device is output whilst the user input is being detected. Alternatively, the display object is caused to appear on the display device over time as the user input is being performed, wherein the rate at which the display object appears is different to the rate of performance of the user input. A device and executable computer program for performing the steps of the method is also provided.

Abstract: An internal combustion engine in which a fuel reforming operation in a fuel reformation cylinder is not executed when a gas temperature of a fuel reformation chamber at a time point when a piston in the fuel reformation cylinder reaches a compression top dead point is estimated to fall short of a reforming operation allowable lower limit gas temperature set based on a lower limit value of a reforming reaction enabling temperature. For example, fuel is supplied from an injector so that an equivalence ratio in the fuel reformation chamber is less than 1. Alternatively, the fuel supply from an injector is stopped. This way, a supply of non-reformed fuel from the fuel reformation cylinder to an output cylinder can be avoided, and knocking in the output cylinder can be avoided.
