Nozzle Holes Effect on Unburned Fuel in Injected and In-Cylinder Fuel of Four Stroke Direct Injection Diesel Engine

Authors : Semin and Rosli Abu Bakar

Abstract: The fuel nozzle is an important aspect for diesel engine combustion performance. The model of four-stroke direct-injection diesel engines is developed in the research to investigate the injected and in-cylinder fuel diesel engine in unburned fuel effect from the fuel nozzle multi holes geometries. Model and simulation in this research is using GT-POWER from the GTise-6.2 software were specially development for internal combustion engines performance simulation. The selected diesel engine is opened, breakdown and measurement of all its components size to input to the window engines component menu of the model. The investigation results output of the simulation is focuses on nozzle holes effect in unburned fuel in injected and in-cylinder fuel process of diesel engine. The holes nozzles from 1 hole until 10 holes in difference orifice diameter have been examined using GT-POWER model simulation and the results shown that the 5 holes nozzle provided the best burning fuel results in any variation engine speeds.
