So, you may need to run more checks to confirm that it is truly the Symptom that corresponds to other engine problems that arise from other And the result will be continuous interruption or vibration of
When the engine isĭenied fuel because injector is going bad in one side, the matching cylinder The engine from the injectors that it uses for combustion.
This, in turn,Ĭauses the car to do convulsive or rough idling. Minute (RMP) will fall below the best level when it is idling. Supply of fuel into the engine and you will notice the car’s revolution per What happens when fuel injectors go bad Rough idling Also, any delay could lead to overheating and theĮngine could stall. Stalling after you have pressed the accelerator, struggling to accelerate and Relate to the smooth performance of the vehicle. This will affect theĬombustion process and cause the engine to misfire amid other problems that Means the engine will not get enough fuel in it. 5 Common fuel injector problems symptoms + solutions to all signs of bad fuel injectors Symptoms of Bad Fuel Injector Over the injectors functions and makes sure the exact quantity of fuel gets to Also, the vehicles Engine Control Unit (ECU) watches What does a fuel injector do?Īssist the internal combusting process. Problem is when it eventually spontaneously. Problems, this would affect the performance of the engine and the car willĪnd being stranded on the highway, it is important you detect fuel injector
How the fuel injector works is that it sprays fuel into But modern vehicles now have complex electronicįuel injection system. The first commercial 4-stroke engine with common rail entered service in early 2001, with a Wärtsilä 9L46D on board a cruise vessel CARNIVAL SPIRIT.Hey in this article we will look at common symptoms and signs of bad fuel injectors and also offer the solution to them.īefore 1980 had carburetors.

It is equipped with a common-rail system for fuel injection and exhaust valve actuation, as well as full electronic control of these engine functions. This engine has no standard camshaft and its gear drive, fuel injection pumps, exhaust valve actuator pumps and reversing servomotors. The vessel is propelled by the world first low-speed diesel engine with common-rail fuel injection: the Wärtsilä Sulzer 6RT-flex58T-B developing 11,275 kW at 93 rev/min. The three fuel injection valves in each cylinder cover are separately controlled so that they may be programmed to operate separately or in unison as necessary.Ī major seamark was passed on 18 September 2001 when the sea trials of the new 47,950dwt bulk carrier GYPSUM CENTENNIAL were successfully completed. The control units regulate the timing of fuel injection, control the volume of fuel injected, and set the shape of the injection pattern. Fuel is delivered from the common rail through a separate injection control unit for each engine cylinder to the standard fuel injection valves. It provides a certain storage volume for the fuel oil, and has provision for damping pressure waves. The common rail is a manifold running along the length of the engine at just below the cylinder cover level. Common-rail injection technology offers the possibility to maintain high injection pressure all the way down to idling and to achieve “ no smoke at any load”. When the injection pressure drops at lower loads, the fuel droplets grow bigger and there is not enough time to complete combustion of these droplets. With mechanical injection systems the fuel injection pressure is a function of engine speed and engine load. The benefits of common rail technology are smokeless operation, lower, stable running speeds (down to about 10 rpm for 2-stroke engines) and reduced fuel consumption at part load. Timing valves determine the timing and extent of fuel delivery to the cylinder injectors. A fuel supply system in which two or more high-pressure pumps supply a common manifold or rail.
