Abstract
A controller (an engine controller 100) allows a fuel to be fed into a cylinder 11 within a range from an intake stroke to a compression stroke, if an engine body (an engine 1) is at a low temperature which is equal to or below a predetermined temperature and is under a load which is equal to or greater than a predetermined load. The controller instructs a fuel injection valve 53 to inject a greater amount of the fuel during the compression stroke than during the intake stroke if the content of an unconventional fuel in the fuel is higher than a predetermined level, and to inject a greater amount of the fuel during the intake stroke than during the compression stroke if the content of the unconventional fuel in the fuel is equal to or lower than the predetermined level.
