Abstract
A gas mixer for mixing gaseous fuel and air for an internal combustion engine is disclosed. The gas mixer may have a housing defining an air path for mixing the gaseous fuel and the air within the air path. The housing may have a narrowed portion. The gas mixer may also have a displacement body axially displaceable and coaxially arranged within the air path. The displacement body and the housing may define an air passage disposed at the narrowed portion. The gas mixer may further have a fuel inlet fluidly connected to the air passage. The fuel inlet may be configured to supply gaseous fuel to the air passage. Further, the gas mixer may have an adjusting unit disposed at least partially within the air path. The adjusting unit may be connected to the displacement body and may be configured to axially displace the displacement body.
