Engine Crankshaft

Taking into account the interaction between the engine oil and the crankshaft to model crankshaft thermomechanical behavior under dynamic loading is very important. In particular, when the crankshaft is working in severe conditions. This paper deal with an air cooled direct injection-type engine crankshaft thermomechanical FEM modelling account for engine oil-cranks half interaction in severe working conditions. As case of application we consider the diesel engine Deutz F8L413. The model takes into account 2 forced convectives heat flux: engine oil and crankcase air. The severe mechanical and thermal characteristics of engine are experimentally measured on a bench test equipped with a hydraulic brake. The temperature distribution inside the crankshaft was computed using the measured temperature as boundary conditions. The most thermo-mechanical stressed zones of the crankshaft have been determined. The fatigue resistance of the crankshaft under thermo-mechanical conditions was examined using Dang-Van multi-axial fatigue criteria. To prove our model efficiency, we have compared crankshaft damage in service to the numerical simulation results. It was found the breakage occurred in an area where the numerical simulations give the highest stresses.

The effects of the shape of the injection diagram, injection period, and injection nozzle on diesel engine smoke have been studied for a wide range of injection timings and engine speeds on a 1-litre direct-injection type engine cylinder. Cycle temperatures were also varied by raising inlet air temperature and by introducing water mixed with diesel fuel. An analysis of these results shows that the exhaust smoke level is mainly determined by the concentration of soot at the end of heat release (net soot release), i.e. any subsequent combustion of the net soot release before exhaust valve opening is unimportant. The net soot release in a diesel engine cylinder, for a given fuel, is controlled by the amount and rate of diffusion burning and the flame temperatures.
