Abstract
Fuel burning is an initial process of burning fuel in the main engine cylinder. The misting is carried out by the injector. The injector is very important in determining the quality of combustion in the cylinder chamber, the penetration and atomization of fuel is regulated by the condition of the injector in order to create an efficient combustion process. The injector will fuel the fuel from the fuel injection pump into each cylinder and in sequence according to the firing order at the end of each compression stroke where the piston (piston) is 14 ° before the top dead center (TDC). With the timing and speed of the correct injection will improve the perfection of combustion in the cylinder. The important thing to pay attention to in the fuel atomizer is the damage that often occurs in the fuel misting system such as the timing accuracy, the fogging speed when compressing, the condition of the fogger and the age of the fogger. However, regular maintenance on the injector is very important in maintaining the fuel injection process, so that the main engine performance on the ship is optimal. As for injector maintenance by means of pressure tests, overhauls, and cleaning regularly, which is usually done after working hours have reached the limit specified in the manual book. To get perfect combustion results, there are a number of things that must be done, namely adjusting the nozzle pressure on the injector valve so that the nozzle produces a pressure of 400 kg / cm2, if the pressure does not reach that number it will cause the exhaust gas temperature to rise and fuel consumption will be wasteful. The time of fogging also affects the perfection of the combustion process, the correct time is 14 ° before the dead center of the fuel begins to atomize at the end of the compression stroke. And you also have to make sure the filters on the fuel are all in good condition, so that the fuel going to the injectors is clean because otherwise it will cause clogging of the injectors, and the injectors will not drain the fuel optimally. Keywords: Injector, Maintenance, Combustion
