FIELD: machine building.
SUBSTANCE: device for pulse ignition of combustible mixture includes a housing with a combustion chamber located in it, a fuel atomiser, an ignition source and an air supply channel. In addition, the device includes a mixing channel connected to the fuel atomiser and the air supply channel. The latter is equipped at the outlet with an airflow rate control. Connection of the mixing channel with the fuel atomiser has the possibility of supplying fuel jets perpendicular to the air flow. A spray nozzle is installed at the mixing channel outlet. The combustion chamber is enveloped with a cooling air jacket connected through the air supply channel to the mixing channel and has several ignition sources equally spaced throughout its length. A convergent conical tube ending with a nozzle is installed at the combustion chamber outlet.
EFFECT: invention allows performing reliable ignition of combustible mixture.
