PROBLEM TO BE SOLVED: To start an engine without remarkably increasing cost and without using a starter motor in an engine starter and a pressure accumulation device. SOLUTION: This engine starter is provided with an injector 29 directly injecting fuel to a combustion chamber 18, an ignition plug 30 igniting an air-fuel mixture in the combustion chamber 18, a crank angle sensor 46 detecting the crank angle of an engine 10, a first PCV passage 31 connecting a crankcase 15 to a surge tank 24, a first cutoff valve 33 freely opening and closing the passage 31, a second PCV passage 34 connecting the crankcase 15 to an air cleaner 26, and a second cutoff valve 37 freely opening and closing the passage 34. An ECU 44 executes ignition as well as fuel injection to a cylinder in an expansion stroke detected by the crank angle sensor 46 when the PCV passages 31, 34 are closed by the cutoff valves 33, 37 before the engine 10 is stopped and a restart command is inputted after the engine 10 is stopped.
