<p>PROBLEM TO BE SOLVED: To stabilize the ignition and combustion of an air-fuel mixture in a direct-fuel-injection internal combustion engine directly injecting a fuel into the combustion chamber of each cylinder.SOLUTION: A direct-fuel-injection internal combustion engine that directly injects a fuel into a combustion chamber of each cylinder and that can emit an electric field into the combustion chamber via an antenna 12 facing the interior of the combustion chamber, is configured to implement the emission of the electric field into the combustion chamber during a multiple-injection period for injecting the fuel a plurality of times in the cylinder before starting an expansion cycle.</p> |
