My project deals with reduction of fuel consumption primarily for trucks. The project focus is to do this by reduction of frictional losses in the piston ring to cylinder liner contact. To do this I am performing multiphysics simulations. The tribological interface is coupled with a deformation model to simulate the effect of out of round cylinder liners. In parallel with this I am also developing a test rig to evaluate the results from the simulation model.
