Coolant fluid leakage detection method for a cooling system of an internal combustion engine (5) of a motor vehicle comprising measuring (10, 20) the temperature at two different instants (T<ti>,T<ti+1>) and comparing (30) measurements taken. If the difference is smaller than a first threshold value (X<1>) restart measuring stages and if it is equal or bigger then measuring (40) the knocking level (K) of the internal combustion engine.

Conversely if knocking level (K) is equal or bigger, then add one unit to the counter. If the resulting counter value is lower than a third threshold value (X<3>), then restart measuring stages and if the counter value is equal to the third threshold value (X<3>), then send (60) a leakage alert.

The present invention relates to the technical field of sealing materials, and discloses a high-temperature vermiculite sealing material for SOFC, and a preparation method thereof. The material is prepared from modified chemically expanded vermiculite and negative-ion high-temperature expanded vermiculite. The modified chemically expanded vermiculite carries positive charges, and the negative-ion high-temperature expanded vermiculite carries negative charges. After the modified chemically expanded vermiculite and the negative-ion high-temperature expanded vermiculite are mixed, electrostatic attraction is generated to achieve combination. The material does not use binders, so that the loss on ignition is significantly reduced without changing the combined strength of the sealing material. The stearate serves as an intercalation agent of chemically expanded vermiculite. The modified chemically expanded vermiculite prepared from the stearate has high-temperature resistant compressive strength at 700°C. The negative-ion high-temperature expanded vermiculite is formed by using negative ion air to treat high-temperature expanded vermiculite to enable the high-temperature expanded vermiculite to load and accumulate negative charges. Using the negative ion air to treat the high-temperature expanded vermiculite does not require the use of chemical agents, the process is simple, and large-scale production can be achieved.
