Project title:

Lubrication of Piston/Cylinder liner contacts in downsized IC engines: Optimization of lubricant additives for Atmospheric Plasma Spray (APS) Coated cylinder liners and DLC coated piston rings

Project vision statement:

To study the tribological behavior of contacts involving different couples of materials which are either already used or at experimental stage for cylinder-liner and existing or new chemistries of lubricants. 

The project will be focused on the contact DLC coated piston-ring/ APS coated cylinder-liners. Moderate to high load in boundary and partial film lubrication will be studied as these regimes are gaining importance along reduction of lubricant’s viscosity. Known and experimental anti-wear and friction modifiers additives will be primarily considered alone or in interference with other additives (detergents, dispersants). 

Scientific objectives of the project:

1) To study tribo-chemical mechanisms with each combination of lubricants and coatings/materials couples and

 2) How the properties of APS coatings (chemistry, nano roughness and open porosity) affect the additives behavior and tribofilm growth.
