Marine Diesel Fuel Injectors
Diesel Services of America wanted to take the time to explain the different Marine Diesel Fuel injectors and their systems, read on to learn about this topic.
Your Marine Diesel Fuel Injectors system is one of the most important components of your boat. Without them, you won’t be able to make it go where you want it to go. So, how do you know which injectors are right for your boat? There are many factors that go into this decision, but here are some things to keep in mind before making a purchase: Exhaust gas fuel injection (EGFI) vs. direct injection Both exhaust gas injection (EGFI) and direct injection use fuel injected directly into the combustion chamber. However, there are significant differences between the two systems – we’ll explore those below. A diesel engine has more than one type of injector: EGFI is an exhaust gas fuel injection system. It works by converting the exhaust gasses after they leave the cylinders into a form that can be injected directly into the combustion chamber. This is what makes EGFI so efficient – it doesn’t rely on “filler” gasses like air or carbon monoxide to push the mixture in order to work. Instead, it forces exactly what is necessary out of the exhaust without adding anything unnecessary or wastefully. This makes diesel engines one of the most efficient engines in existence – they produce very little CO compared to natural gas or LPG fueled counterparts.
What is exhaust gas fuel injection?
Exhaust gas fuel injection is a technology that injects fuel directly into the combustion chamber to increase the fuel efficiency of internal combustion engines. The most common type of exhaust gas fuel injection is called direct injection, and it is achieved with fuel injectors.
EGFI injectors EGFI injectors use an engine’s exhaust gas as fuel. The major advantage of EGO and EGR engines is that these engines can use the full volume of the exhaust gas as fuel. With other types of engines, such as inline-four and V6 engines, you can select which types of exhaust gas fuel injection you want to use. EGFI vs. DME injectors EGFI vs. DME is perhaps the most common comparison made when comparing fuel injection systems. Both types of fuel injection are known for high fuel efficiency and low emissions, but the main difference between them is in the method used to inject fuel. In a DME fuel injector, the injector actually ia prints a map to the engine camshaft to adjust the timing of the engine to deliver the right amount of fuel to each cylinder. This is known as a diary adjustment and is only used when running a DME-equipped engine. In an EGR fuel injector, the injector itself changes the mixture of fuel delivered to the engine. With an EGR-disadvantaged engine, this is not possible.
