The fuel injection system is what most people refer to as the heart of the diesel engine, and also the technology that most of us have never even heard about. There are many different types of fuel injection systems in use nowadays which can vary based on the engine built. In this article we are going to look at some of these:
- Single-point fuel injection system
In this type of system, the injector is located at one point and delivers fuel directly to the engine’s combustion chambers. The fuel is injected by a small spring-loaded plunger that moves up and down as the pressure in the chamber rises and falls. The main advantage of this system is its simplicity; it’s easy to install and maintain. However, it doesn’t provide any control over how much fuel is added or how fast it flows into the engine.
The single-point fuel injection system is a simple and cost-effective way to direct fuel to the engine. It consists of several nozzles that send fuel into each cylinder individually. The nozzles are mounted on the intake manifold and can be adjusted by using a screwdriver to open and close them.
- Multipoint fuel injection system
Along with single point, the multipoint system is also the most popularly used fuel injection system In Si Engine. In a multipoint system, there are several injectors placed around each cylinder head (or other location), which can be used singly or together to deliver more precise tuning for each cylinder. This can be done by varying the amount of fuel delivered by each injector, or by turning them off altogether if necessary (e.g., when you’re not using your car). The main advantages of this type of system include better control over how much fuel is added and how fast it flows into your engine; however, they also require more complex installation procedures than single-point systems do. This type of system requires more sensors than a single-point setup, but it’s easier to maintain because there aren’t as many components involved in its operation. The sensors monitor air pressure, temperature and other factors that affect how much fuel should be delivered to each cylinder at any given time.
- Sequential fuel injection
This is the simplest type of fuel injection system. It consists of a single injector, which fires all the time, but in a different sequence depending on the engine speed. The sequential system was used in early cars but has been mostly replaced by direct injection systems. This method is used in most modern cars and trucks, including those with turbochargers. The pistons move up and down as they compress the air/fuel mixture into cylinders.
- Direct injection
Direct injection systems have all their valves at one end of the cylinder and injectors at the other end. This allows for much better control over how much fuel is injected into each cylinder as well as making it easier to change between fuels (e.g., gasoline and diesel). Direct injection is a more recent development in automotive technology that has been widely adopted by several manufacturers because of its ability to improve performance and fuel economy at low engine speeds (i.e., idle). This method uses a single needle valve located directly above each injector that draws fuel directly from a tank through an electronic control unit (ECU). The ECU monitors pressures and temperatures in real-time, which allows it to deliver precisely measured amounts of fuel at specific times during each cycle when needed most by the engine’s combustion chamber and intake tract.
