INTERNAL COMBUSTION ENGINE START CONTROL SYSTEM

摘要

Provided is a technique for starting fuel injection under condition that ignition and combustion of the injected fuel can be performed upon start of an internal combustion engine. An internal engine start control system estimates a crankshaft rotation amount during a period from a cranking start to the moment a crank position sensor starts output of an effective pulse signal and decides whether to inject fuel at the initial fuel injection timing in accordance with a crankshaft stop position specified by the estimated amount.
