Abstract
An in-cylinder injector injects fuel to be sprayed in the form of an inverted letter V sandwiching a spark plug, as seen in a top view, and in a sector as seen in a side view. The sprayed fuel interferes with an intake valve assuming an open position. An engine ECU executes a program including the steps of: determining with reference to a map a timing of injection of the fuel through the in-cylinder injector (S); determining a period for injection from an amount of fuel injected (S); determining in accordance with map whether the sprayed fuel interferes with the intake valve (S); modifying the period for injection to be advanced by a period for injection having the sprayed fuel interfering with the intake valve (S); and determining a timing of injection and a period for injection (S).
