High Temperature Tribological Lubricants for Low Heat Rejection, High Temperature Operation Diesel Engine
Agency / Branch:
DOD / ARMY
Phase II work focuses on developing an improved high-temperature engine lubricant base stock which will have acceptable vaporization rate and deposits at 875 deg F top ring/liner temperature. Actual lubricating film between the ring face and cylinder liner will be produced by use of a dry-film lubricant additive to the base stock. (Other forms of delivery of dry-film lubricant will be evaluated as part of Phase II also.) The cylinder liner surface character will be modified utilizing a laser integral to the honing process. The objective is to provide micro pockets for retaining residual quantities of dry-film lubricant in the upper ring turn-around area. Work is also planned to evaluate the above stock/dry-film lubricant in conjunction with an advanced liner/ring surface which would form a compatible system capable of operating at 875 deg F.
