FIELD: engine devices and pumps.
SUBSTANCE: starting nozzle contains a fuel injection circuit, a fuel ignition circuit including a fuel injector fed by the fuel injection circuit, and a spark plug for igniting the injected fuel. The starting nozzle also comprises a split shell including a first compartment in which fuel is ignited by means of the spark plug and a second compartment separated from the first compartment by a heat-conducting partition. In addition, the starting nozzle comprises a main combustion starting circuit, which includes one additional fuel nozzle supplied by means of the fuel injection circuit, and in this case, opens into the second compartment of the shell so as to inject fuel in the direction of the wall. The invention also relates to a combustion engine and a turbine engine, each of which comprises at least one such starting nozzle.
EFFECT: invention enables to implement start-up of the combustion chamber irrespective of engine speed and provides fast ignition of fuel, which increases fuel economy.
