Cooling system for an internal-combustion engine of a motor vehicle with a thermostatic valve having an electrically heatable expansion element |
摘要 |
In the case of a cooling system for an internal-combustion engine of a motor vehicle comprising a radiator and a thermostatic valve equipped with an electrically heatable expansion element, it is provided that, by means of three comparison stages which are connected in parallel, specifically a speed comparison stage, a load condition comparison stage and an intake air temperature comparison stage of a control, electric energy can be supplied to the expansion element of the thermostatic valve so that, depending on the demand, the temperature level of the coolant and thus of the internal-combustion engine switches from a high temperature level to a lower temperature level; that is, increases the cooling output depending on the demand.
