Abstract (en)
The engine is cooled by a rheological fluid which in its passive state has a lower thermal conductivity value than in its activated state. The rheological fluid in its passive state has a thermal conductivity value of about a third with regard to the thermal conductivity value of water, and in its active state has a value of somewhat more than three times the thermal conductivity value of water. The rheological fluid has a base substance of silicone oil and a thermal conductivity value range of 0.2 to 1.88 watts per metre kelvin.
