Diesel Injectors Maintenance

Fuel injectors are the main players in this system. These pieces make sure that the engine is receiving the perfect amount of fuel in that moment.

The Diesel Injector Experts

Diesel injectors have nozzles which are used to atomize the fuel with precision and distribute the fuel into the combustion chamber. This is done in such a way that it creates optimal combustion within the chamber.

The range of nozzles is diverse and covers all conventional injector applications. The main manufacturer for injectors is Bosch and their experience and expertise are unrivalled. This makes them the go to for most vehicle manufacturers around the world.

Technical Features of the injectors are as follows

The clearance of moving parts stands at 0.002 mm
The fuel is injected into the combustion chamber at a pressure of 2,000 bar
The injected fuel quantity varies between 1 mm and 350mm cubed and is forced through an opening of just 0.25mm
Fuel injection happens much fast than the blink of an eye

Diesel Injectors Preventative Cleaning

Preventative Cleaning of your engine can enable you to restore engine parts rather than replace them which can be a costly exercise, thereby saving vehicle owners on expensive parts like new turbochargers, catalytic converters DPF’s and EGR units.

These issues usually result from poor combustion which blocks the engine. So before replacing parts try a Hydrogen Carbon Clean a dirty engine first, which may get rid of the build up depending on just how blocked up it is.

Types of Diesel Injection

Direct Injection

Direct injection utilises a Unit Injection System which is electronically controlled, this system was developed by Bosch for direct diesel injected cars and light commercial vehicles of up to 5 litre engines with up to 312 hp.

Special features of the Unit Injector System is that an individual pump is used for each cylinder, therefore the pump and injector are one piece and designed as a compact unit which is installed directly into the cylinder head. This allows pressures of up to 2,200 bar.

The advantages of this type of injector are as follows

  • High Performance for cleaner and more powerful engines
  • Higher engine power combined with lower fuel consumption and lower emissions
  • Higher degree of efficiency due to a more compact design
  • Lower noise level
  • Higher injection pressures allowing for better fuel-air mixture

Common Rail Injection

Common rail injection was introduced by Bosch in 1997 and is different to the direct injection system in that it utilises a fuel rail connected to each injector and a separate pump. This allows for a constant pressure to all injectors at the same time.

With the direct injection system, the fuel pressure must be generated individually and with the common rail system the pressure and injection are separate, meaning the fuel pressure is constantly available.

Pressure generation takes place in the high-pressure pump, this pump compresses fuel and feeds it through a high-pressure pipe and into the fuel rail, which acts as a shared high-pressure reservoir for all of the injectors. From there the fuel is distributed to the injectors which then injects the fuel directly into the combustion chambers.

Some of the advantages of a common rail system are as follows

  • high engine power with smoother running and lower fuel consumption
  • Cleaner and highly fuel-efficient fuel injection due to shorter spray times
  • Can be used with all vehicles due to a modular design.
