Air/fuel mixture laser ignition method for internal combustion engine, involves igniting air/fuel mixture by using laser ignition in pre-chamber during approximation at upper dead center of piston
Air/fuel mixture laser ignition method for internal combustion engine, involves igniting air/fuel mixture by using laser ignition in pre-chamber during approximation at upper dead center of piston
The method involves supplying an air/fuel mixture diluted with air or exhaust gas through over-flow channels (4) during a compression period of a main combustion chamber (5). The mixture is ignited by using laser ignition in a pre-chamber (2) during approximation at an upper dead center of a piston, where the pre-chamber is connected with the main combustion chamber by the over-flow channels. A mixture condition suitable for the laser ignition is adjusted at an ignition point (10). An independent claim is also included for an arrangement for laser ignition of an air/fuel mixture.
