Abstract
An internal combustion engine having an auxiliary combustion chamber is disclosed. The engine comprises a main combustion chamber defined by a cylinder, a piston reciprocably disposed in the cylinder, and a cylinder head. A main passage intercommunicates the main and auxiliary combustion chambers. The auxiliary combustion chamber is divided into first and second sub-chambers. A fuel injection nozzle is disposed in the second sub-chamber so that the fuel injected therefrom is directed to a recess in the first sub-chamber. The main passage opens into a portion of the first sub-chamber which is substantially symmetrical to the recess. Electrodes of a spark plug are disposed in the recess. Also, a sub-passage, which opens into the recess, may be provided for intercommunicating the main passage and the recess.
