How diesel fuel injection system works

A fuel injection pump is a very complex piece of engineering. Each one is calibrated to deliver just the right quantity of fuel via the fuel injector into the combustion chamber. This ensures the maximum power output and optimum fuel efficiency. Although their complexity makes it complicated to replace individual parts, it is relatively easy to fit entire replacement units into place.In most cases, the injection pump is driven indirectly from the crankshaft by gears, chains or a toothed belt – often the timing belt – that also drives the camshaft. It rotates at half the speed of the crankshaft in a conventional 4 stroke engine.The timing is precisely set according to the model of engine it services, so that the fuel injection pump introduces the right volume of diesel into the cylinder chamber only a fraction of a second before the cylinder reaches the top dead centre position of its compression stroke. This ensures the fuel only becomes available from the fuel injector at the critical point of the cycle. At this point, the heat generated from the very high compression in the piston causes the diesel fuel to ignite, generating power for the engine.

Fuel injection pumps are precision engineered components

Because fuel injection pumps operate thousands of times a minute, ensuring their reliability is a key challenge for any supplier and our own genuine pumps, backed by a 12 month warranty, have been engineered for the precise requirements of your engine.Our fuel injection pumps are designed to the highest specification and ensure that we give you precise calibration and fuel delivery. In turn, this helps to optimise your combustion cycles, thereby maximising your power, efficiency and fuel consumption.Although we have tried to make the installation process as simple as possible, in practice, you may need the help of your local distributor. It is important to ensure the setup is correct as the fuel injection pump plays a role in limiting the emissions from your engine.
