Abstract: A cooling arrangement for a liquid-cooled internal-combustion engine of a motor vehicle has a temperature-controlled thermostatic valve, through which the coolant is completely or partially either guided through the radiator or, through a short-circuit pipe between the forward flow and return flow pipe, is guided past the radiator, with the distance covered by the motor vehicle after the vehicle start being compared with a limit distance. This limit distance is determined such that, when the limit distance is covered in the normal driving operation, the coolant temperature in the coolant circuit of the internal-combustion engine remains well under the opening temperature of the thermostatic valve which is not acted upon by current and therefore under the boiling temperature. The thermostatic valve is acted upon by current from the vehicle start as long as the distance covered after the vehicle start is shorter than the limit distance.

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.
