Abstract
A stop-start control apparatus for a port injection engine () including cylinders () stops the engine () by stopping fuel injection from each injector (), when a predetermined stop condition is fulfilled. An estimated position of a piston () in each cylinder () after the engine () is stopped is determined during a stop process period from when the predetermined stop condition is fulfilled until when the engine () is stopped, and a compression stroke cylinder in which the piston () is to be stopped in a compression stroke is identified. An amount of fuel to be injected from the injector () for the compression stroke cylinder during the stop process period is set based on the estimated position of the piston () in the compression stroke cylinder. The injector () injects the fuel in the set fuel amount so that the fuel is contained in the compression stroke cylinder when the engine is stopped.
