Henault, C; Cochard, P

An internal-combustion engine fed with a stratified charge is comprised of an inlet leading into a combustion chamber for feeding a main charge of a lean mixture of a first fuel and air, and an injection device for injecting a second fuel into an ignition zone of the combustion chamber in an amount such that the mixture of the second fuel and the air contained in the lean mixture, in the ignition zone at the time of ignition, attains the level of the ignition richness of the second fuel. Thereby, the second fuel undergoes ignition and combustion and effects flame propagation to produce ignition of the first fuel. A holder with a ball valve protects the fuel injector of the injection device by obturating the injector at the end of the compression stroke and during ignition and the subsequent expansion stroke.
