“…When the injection pressure will increase, the fuel particle becomes small. If the injection pressure is too high, the ignition delay period becomes shorter and hence the possibilities of homogeneous mixture reduced and eventually the combustion efficiency dropped (6,7) . For lifetime verification of an automotive components it is important to simulate injection phenomena in a test bench that certainly regenerate some more boundary conditions to understand the fuel system design which will help researchers to elevate a more stable future test bench system.…”

This study discusses a fuel injector test bench containing a mechanical type fuel supply system for heavy duty diesel engine. The main focus of this study was to evaluate the design stability of the test bench, which basically measures the injector durability of a multi-hole heavy duty injector by using pure diesel as a test fuel. In this experiment, diesel spray was controlled by a specially designed control box and all the experiments were carried out to measure e.g. fuel injection pressure and fuel injection quantity to understand the injection status which is interlinked with the stability factor of total test bench design. Also, the durability test was performed to understand the heavy duty operation lastingness of the designed system and the flow rate of the installed distributor pump in the fuel supply system of this studying test bench was compared with LO-1 and LO-2 pump. The results of the above mention tests revealed that the injector test bench design and control system can serve the purpose for heavy duty injector.

“…The details of the diesel engine design vary significantly over the engine performance and size range. In particular, different combustion chamber geometries and fuel injection characteristics are required to deal effectively with major diesel engine design problem achieving sufficiently rapid fuel-air mixing rates to complete the fuel-burning process in the time available [15][16][17][18][19][20][21][22][23] . A wide variety of inlet port geometries, cylinder head and piston shapes, and fuelinjection patterns used to accomplish this over the diesel size range [1,10] .…”

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
