The method also includes calculating an average fuel-consumption when the current fill-level matches the stored fill-level, based on distance traveled since the refueling process and a total amount of fuel received by the vehicle, as indicated by stored fuel-dispensed data received from one or more fuel pumps, since the stored fill-level was stored.

Abstract: A liquid-cooling engine system is described with a coolant control device having an adjustable control element capable of independently controlling the flow of coolant through a cylinder head and cylinder block. The device contains a rotatable drum that can be rotated along its longitudinal axis to expose holes and thereby allows coolant circulation based on a temperature within the engine system. The coolant control device has three positions but may also be fine-tuned within each position to control the flow of coolant through the cylinder head and cylinder block in order to adjust the amount of heat extracted according to demand, which serves to control the liquid-type cooling circuit in a demand-dependent manner that accounts for the operating modes of the internal combustion engine.
