Abstract
An engine () includes an engine body, an injector (), and an engine controller (). The engine body includes a piston () inside a cylinder (), and a combustion chamber () defined by the cylinder () and the piston (). The injector () injects fuel containing at least gasoline into the combustion chamber () via a nozzle port (). The engine controller () allows the injector () to inject the fuel in at least a second half of a compression stroke, and controls an injection condition of the injector (). The injector () has a parameter for adjusting spread of fuel spray. The engine controller () adjusts the parameter to increase the spread of fuel spray with an increase in pressure in the combustion chamber ().
