Things you need to know about the fuel injection system

Posted June 10, 2021 by dieselinjection

Indirect fuel injection is used in petrol-powered vehicles. The fuel is delivered to the engine compartment by a fuel pump and then injected into the inlet manifold by an injector.
The proper amount of fuel/air mixture must be delivered to the engine for it to perform smoothly and efficiently over its wide range of demands. The carburettor, which is far from flawless, has traditionally been in charge of the fuel/air combination.

Fuel-injected engines, in which the fuel is delivered in precise spurts, are currently found in many cars. Engines with this technology are usually more efficient and powerful than those with carburettors, and they can also be more affordable while emitting fewer harmful emissions.

Introduction to diesel fuel injection

In petrol-powered vehicles, the fuel injection system is always indirect, with petrol pumped into the input manifold or intake port rather than directly into the combustion chambers. Before the fuel enters the chamber, it is thoroughly mixed with the air.

Many diesel engines, on the other hand, use direct injection, in which the diesel is injected directly into the compressed air-filled cylinder. Others employ indirect injection, in which the diesel fuel is injected into a specifically formed pre-combustion chamber connected to the cylinder head by a short tube.

Injection of the most fundamental kind

Indirect injection is used in all modern gasoline injection systems. A unique pump transports fuel under pressure from the fuel tank to the engine compartment, where it is delivered separately to each cylinder while still under pressure.

The fuel is fired into either the inlet manifold or the inlet port via an injector, depending on the system. Diesel injection nozzle acts similarly to a hose's spray nozzle, ensuring that the fuel is dispersed as a fine mist. The fuel/air combination enters the combustion chamber after mixing with the air entering through the input manifold or port.


Multi-point fuel injection is used in some vehicles, with each cylinder receiving its injector. This is a difficult task that can be costly. Single-point injection, in which a single injector feeds all of the cylinders, or one injector for every two cylinders, is more prevalent.
