Cortec® VpCI®-649 BD has gained global adoption among major diesel engine manufacturers as a high-performance solution for corrosion protection during engine hot testing and subsequent cold storage. Utilising Vapour phase Corrosion Inhibitors, the treatment forms a protective film that prevents internal engine rust caused by testing water and residual moisture.
Cortec® VpCI®-649 BD is now the go-to corrosion solution for hot engine testing by multiple global diesel engine manufacturers. As more facilities across North and South America, Europe, and Asia realise the advantages of VpCI®-649 BD for engine hot testing and outdoor storage, Cortec® stands ready to extend the same technology and technical support that has made life easier for engine makers around the globe.
Engine internals are at risk from corrosion caused by water used during hot engine testing and fill-and-flush activities. Corrosion affects the like-new appearance of the engine and threatens its structural integrity. The addition of VpCI®-649 BD makes a significant difference by leaving behind a protective film of Vapour phase Corrosion Inhibitors. These diffusers spread throughout the surrounding compartment to inhibit corrosion, even in the presence of residual water, months into storage.
In May 2023, a major manufacturer of off-road engines started full-scale testing of VpCI®-649 BD to address corrosion concerns. They now add a 3% solution of VpCI®-649 BD to the cooling system for an hour of hot testing, and a 5% solution of VpCI®-649 BD (combined with glycol) for engines that are subsequently stored in cold climates.
Eight months into the trial, the engine maker declared their corrosion problem cured and began to spread the word to global counterparts, who have since started adopting the same solution. While VpCI®-649 BD was initially used to protect the cast iron of very large engine blocks, it is now being considered for smaller engines with aluminium components, such as those in the automotive industry.
