SIMULATION OF AN INTERNAL COMBUSTION ENGINE USING ECFM-3Z COMBUSTION MODEL IN A CFD 3D COMMERCIAL CODE COMPARED TO EXPERIMENTAL RESULTS

This paper presents the simulation model of an oil lubrication gerotor pump for the internal combustion engine. The model was constructed by using a mono-dimensional commercial code taking into account all the phenomena that occur during the revolution of the pump shaft. First of all, several geometric considerations and theoretical observation are presented. An experimental campaign was also performed to validate the simulation model. In these experimental tests particular attention was regarded to the behavior of the pressure oscillations during the pump shaft revolutions. The final aim of this activity is to obtain an instrument that allows in-depth analysis of pump and lubrication circuit functioning and that can be coupled with other models (e.g. VVA, VVT, etc.) in order to take into account different problems of the hydraulic components of engines.

Primary Coil

In the paper, by means of the method of directly measuring the discharge voltage and discharge current of ignition coil, the match between hydrogen internal combustion engine (HICE) and ignition coil is studied, and the experimental research of ignition coils’ charging and discharging characteristics is carried out which leads that more accurate discharge energy is obtained. The experimental results show that the ignition coil here meets the need of the ignition of HICE; the energy corresponding to the pulse width of 5ms is the maximum one the primary coil can store; with pulse width constant the oscillation of the voltage leads to different discharge durations; the larger the charge pulse width is, the lower the utilization of coils is.

Theoretical Performance

Twin crankshaft is a new engine arrangement introduced to overcome cylinder’s liner wear problems encountered in the conventional inline crankshaft engine due to the effect of the side thrust force. The offset crankshaft arrangement was also introduced to solve the same problem. In this work a computer programs was built to obtain the theoretical performance comparison between the three engines arrangements (inline, twin and offset crankshaft engines), and compared the theatrical performance with the experimental results, which done to the engine’s models. The study results show that the twin crankshaft engine model exhibited no thrust force, and that the thrust force in the offset crankshaft model is smaller than that in the inline crankshaft engine model. These agree with experimental results obtained from the same engine model.
