FIELD: engine construction.
SUBSTANCE: invention relates to engine construction, in particular to forced medium-speed gas engines operating in a wide range of rotational speeds and loads. The combined pre-chamber is an assembly module containing mounted in its case 2 dosing solenoid valve for gas supply with electric connector 12 for connecting the control electronic system, spark plug 18 and nozzle tip 20 for removing the burning gas-air mixture to the main combustion chamber. The coupling of the pre-chamber with cylinder cover 1 is made in the form of a conical connection, which allows for heat removal from the nozzle tip to the cooled support surface of the cover.
EFFECT: invention makes it possible to simplify the gas supply system when converting a diesel engine into a gas engine by using combined pre-chambers installed in each of the cylinder covers of a multi-cylinder engine instead of injectors.
