ENGINE CORROSION STUDY ON INSTALLED ENGINES AS A COMPONENT OF A COMBAT VEHICLE IN OUTDOOR STORAGE AT ANNISTON ORDNANCE DEPOT, ANNISTON, ALABAMA, CONDUCTED JULY 1958 - OCTOBER 1961

Abstract

An attempt was made to increase the reprocessing cycle of installed engines in vehicles stored outdoors from the presently used one year to a minimum of 3 years. Despite improvements in application techniques, corrosion still occurs primarily in the cylinder area in less than one year. VCI oil proved far superior to the presently used MIL-L-21260 oil after a minimum of 3 years outdoor storage under actual conditions. Of 24 cylinders (2 test engines) using the VCI oil 17 were corrosion free after 3 years. The other 7 cylinders developed spotty and not too severe corrosion during the 3rd year of storage. MIL-L-21260 oil displayed sufficient corrosion on 12 of 24 cylinders to question satisfactory operation of the engine after reassembly without considerable rework and/or salvage. Half of the cylinders showed corrosion in the first year. There was no apparent attack from the VCI oil or VCI crystals on nonferrous or nonmetallic components of the engine.
