Abstract
A carburetion arrangement and method of carburetion for a multicylinder internal combustion engine wherein at least one carburetor acts as a main mixture forming device with the main mixture being guided through individual intake lines which connect the carburetor to intake valves of the engine. Further mixture components are guided through separate air and fuel lines which terminate in the individual intake lines with the separate air and fuel lines being combined immediately before the intake lines. The intake air is supplied to the further mixture components primarily through the individual intake lines with a volume controlled portion of the intake air of this mixture component, reduceable to zero, being guided through the separate air lines, as correction air for the fuel to the mixture components flowing through the separate fuel lines. The correction air flowing through all the lines is controlled volumewise by a common control device which is disposed upstream of an air distributor for the air lines. The fuel is fed to the separate fuel lines commonly and at zero pressure from the carburetor as well as to individual inlets in the respective intake lines by way of a fuel throttle nozzle located in a vicinity of the individual inlets.
