Computational Simulation of Fuel Nozzle Multi Holes Geometries Effect on Direct Injection Diesel Engine Performance Using GT-POWER
The computational model simulation development is use the commercial computational fluid dynamics of GT-POWER 6.2 software were specially development for internal combustion engines performance simulation. The research concentrated on one dimensional model and focuses on fuel nozzles multi holes geometries variation developed from all of the engine components size measurement of the original selected diesel engine. All of the measurements data input to the window engines component menu for running input data in the model. Results of the diesel engine fuel nozzles multi holes geometries model simulation running is in GT-POST. The model performance shows in engine cylinder and engine crank-train on software window output. The performance analysis effect of the model investigated of fuel in-cylinder engine, indicated specific fuel consumption, indicated torque and indicated power of engine modeled. The simulation result was shows that the seven holes nozzle provided the best burning for fuel in-cylinder burned and the five holes nozzle provided the best for indicted power, indicated torque and indicated specific fuel consumption in any different engine speed in simulation.
