Therefore in general, (regardless of thermo-mechanical drive 3 whenever needing to enhance cooling capacity related with engine speed How), electric drive 4 is just activated.
For example, in one embodiment (pump group 1 includes the thermo-mechanical drive 3 with " the classical pulley " of mechanical type, because This cannot be controlled electronically, and it is still cold above-mentioned " preheating " stage that above-mentioned throttle valve, which is in wherein engine, and is needed Heated as quickly as possible), the amount of the coolant in circulation is adjusted by the positioning of control throttle valve.
