Newly manufactured engines are usually tested for a short period of time prior to assembly in the vehicle. To ensure cooling during this test, a hot test fluid is necessary.
The so-called hot test fluid is drained after the engine test run. Nevertheless, a small quantity of fluid remains in the engine block. The internal surfaces of the engine are exposed to the atmosphere and are at risk of corrosion during transportation. If an unsuitable test fluid is used during this test phase, this could lead to corrosion of the internal parts of the engine during transportation from the engine plant to the assembly plant or final location. Therefore, the drained engine requires specific measures to protect it against corrosion during storage and transportation.
Arteco has considerable expertise in this field and can propose novel hot test fluids that provide corrosion protection both in liquid and vapour phase.
