Friction Power Loss Reduction for a Marine Diesel Engine Piston

Free-Piston Diesel Engine Dynamics and Control

Free-piston diesel engines are characterized by freely moving pistons without any rigid crankshaft or camshaft connected to the pistons. This allows a highly compact and e cient engine design, but requires automatic control of the piston motion. This paper present a dynamic mathematical model of a free-piston diesel engine, a control oriented dynamic analysis, and a novel computer-based piston ...

Thermo-Mechanical Fatigue Life Assessment of a Diesel Engine Piston

Optimization of Piston for Diesel Engine Using Kriging Model

Diesel engine combustion chamber which reduces exhaust emission has been designed using CFD analysis and optimization techniques. In order to save computational time for design, the Kriging model, one of the response surface models, is adopted here. For the robust exploration, both the estimated function value of the model and its uncertainty are considered at the same time. In the present prob...
