FUEL GAS ADMIXING PROCESS AND DEVICE

摘要

In an internal combustion engine, natural gas is injected through a nozzle (17) into a curved feeding pipe (13), tangentially and in opposite direction to the flow of combustion air. Two nozzles (17) that are spaced apart in the flow direction and that alternatively inject the natural gas are preferably used in order to achieve a homogeneous distribution of fuel in the fuel/air mixture. A conical jet (21) ensures an impeccable mixture of gas with the totality of supplied air.
