<p>PROBLEM TO BE SOLVED: To suppress a fuel from being blown out from an intake port to an exhaust port and accelerate gasification of the fuel, thereby improving engine combustion efficiency.SOLUTION: The present invention relates to an engine fuel injection controller comprising: an engine 14 that includes an intake valve 33 opening or closing an intake port 28 of a combustion chamber 27 and an exhaust valve 35 opening or closing an exhaust port 31 of the combustion chamber 27; and a fuel injector 88 injecting a fuel toward an intake passage 86 communicating with the intake port 28 of the combustion chamber 27. The engine 14 is configured to be switchable over between a first operation state in which the intake valve 33 is opened at predetermined timing and a second operation state in which the intake valve 33 is opened at later timing than the timing of the first operation state. The fuel injector 88 injects the fuel in an exhaust stroke of the engine 14 while the engine 14 operates in the second operation state.</p> |
