Abstract:
An engine (1) is provided with an engine body having a piston (15) provided inside a cylinder (11) and having a combustion chamber (17) divided by the cylinder (11) and the piston (15), an injector (33) for injecting fuel containing at least gasoline into the combustion chamber (17) via a nozzle hole (41), and an engine controller (100) for causing the injector (33) to inject fuel at least during the latter half of a compression stroke and controlling the injection mode of the injector (33). The injector (33) has a parameter for adjusting the reach of fuel spray. The engine controller (100) adjusts the parameter so that the reach of fuel spray increases as the pressure of the combustion chamber (17) rises.
