PROBLEM TO BE SOLVED: To suppress a misfiring frequency at the first combustion in a cylinder stopped in an intake stroke when an engine is stopped.;SOLUTION: In an automobile having an idle stopping function, when an engine starting condition is met at S205, a fuel quantity Q1 to be first injected into the cylinder Cyin is read in at S220 based on a piston stop position Pin of the cylinder Cyin stopped in the intake stroke and the fuel quantity Q1 is injected into the cylinder Cyin at S230. By this, since the fuel quantity Q1 is increased and injected to an intake port of the cylinder Cyin when suction ability is low responsive to the piston stop position Pin of the cylinder Cyin, can suppress the misfiring frequency at the first combustion and improve the startability of the engine. When the fuel quantity Q1 read at S220 is zero, the cylinder Cyin is not used for the first combustion and deterioration of emission can be prevented.;COPYRIGHT: (C)2006,JPO&NCIPI
