Abstract: A mixture formation device for an internal combustion engine operated with a burnable gas, preferably compressed natural gas CNG, comprises a combination of a quantity regulator, a gas mixer, a flow-guiding element for pressure recovery, and a connection possibility for exhaust gas recirculation of the internal combustion engine. The mixture formation device according to the invention can empty a gas tank to a comparatively low pressure of approx. 2 bar, an excellent mixture formation being achieved over the entire range of speed and load range of the internal combustion engine. According to the invention, such a mixture formation device can reduce production costs as well as space requirements compared to known solutions. An internal combustion engine operated with a burnable gas, particularly compressed natural gas (CNG), may also comprise such a mixture formation device in the intake tract thereof.

Abstract: The invention relates to a mixture formation device for an internal combustion engine that is operated with a combustible gas, preferably compressed natural gas (CNG). The mixture formation device comprises a combination of a quantity regulator, a gas mixer, a flow guide element to recover pressure as well as a connection capability for recirculating the exhaust gas of the internal combustion engine. Owing to the mixture formation device according to the invention, a gas tank can be emptied down to a relatively low pressure of approximately 2 bar, whereby an excellent mixture formation is achieved over the entire speed and load ranges of the internal combustion engine. It is provided that, owing to the mixture formation device according to the invention, the installation space requirements as well as the production costs can be reduced in comparison to prior-art solutions.
