The study of the engine combustion system with the direct injection of the methane fuel is introduced. Very short time available for the injection and poor penetration and mixing of the gas jet with the surrounding air cause the serious problems with the combustion initiation. The preliminary results of studies of the ignition of the gaseous fuel jet in single compression machine with the special ignition chamber are presented. The ignition takes place within the prechamber and the hot, chemically active combustion gases saturate the methane fuel jet, which enters the main chamber where the mixing and combustion processes are continued. The results of the investigations aiming at obtaining of the efficient and repetitive ignition of the methane fuel jet are presented. The various versions of the combustion chamber were investigated. The investigations were supported by the results of the numerical calculations of the injection and mixing processes. It has been concluded that that type of the combustion system has the potential to obviate the difficulties to obtain the repetitive ignition of the methane fuel jet.
