The Fuel Injection System

A modern fuel injection system technically includes some sort of a sensing mechanism to determine the correct amounts of fuel that need to be sprayed into the engine’s intake manifold. Another mechanism is needed to deliver or spray the ‘computed’ amount of fuel into each cylinder. This is the function of fuel injectors which we will be discussing in greater detail in the following section.


There are two types of fuel injection systems that generally correspond to the two fundamental types of engines we have in the market today.


The way in which some engines are designed require the fuel to be delivered or sprayed directly into the combustion chamber of the engine. Each cylinder is already filled with compressed air. When atomized fuel is injected into each cylinder it self-ignites. This is true for most diesel engines. We said ‘most’ because there are certain diesel engine designs that move fuel to a pre-combustion chamber first before reaching the cylinder.



Cars that run on petrol have indirect fuel injection systems. Pressurized fuel is delivered to the engine bay from the car’s fuel tank. The pressurized fuel is delivered to the intake port or the intake manifold, depending on the design of the engine. This allows the fuel to be mixed first with air that passes through the inlet port or manifold before the mixture is pushed into the combustion chamber.

The latest cars of today come with multi-point injection. In this system, each cylinder receives fuel from one specific fuel injector. So, if you have 6 cylinders you can also expect 6 fuel injectors. It is this 1:1 configuration that makes this system very powerful and efficient, albeit complex and expensive to fix. Most cars, however, have a single-point fuel injection system or even an injector for every two cylinders.
