Abstract (en)
[origin: WO2018104107A1] The invention relates to a mixture formation device for an internal combustion engine operated with a burnable gas, preferably compressed natural gas CNG. The mixture formation device 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. The invention also relates to an internal combustion engine operated with a burnable gas, particularly compressed natural gas (CNG), comprising such a mixture formation device in the intake tract thereof.
