Abstract
Even when an engine is started in various combustion states, an excessive increase in engine speed at the start of the engine is suppressed without an influence of the combustion states and with an excellent responsiveness. Ignition timing (or a combustion injection amount) at the start of an internal combustion engine is corrected in accordance with a crank angle cycle ratio which is a ratio of a combustion period crank angle cycle and a reference crank angle cycle.
