A tribochemical analysis of lubricants from field trials of hydrogen assisted dual fuel internal combustion engines

The paper reports on the tribological performance of lubricant samples siphoned from hydrogen-assisted diesel engines of trucks participating in a real-world field trial. Lubricant rheology, as well as the ability of the residual additive package in forming tribo-films generated through tribometry a...
