Abstract
There is disclosed a fuel supply control apparatus for a multi-cylinder internal combustion engine having an injector with air assist, a reasonable system in which injection is made during intake stroke when air assist air is supplied by the air assist, and injection is made during exhaust stroke when no air assist is effected, and an air assist volume, a droplet size and an operating condition are combined. With this construction, the fuel injection timing is shifted from the intake stroke side to the exhaust stroke side in accordance with an air assist volume so as to enhance the exhaust gas quality in which optimum micro-granulation and atomization of fuel are held, the fuel efficiency and the drivability.
