Correct Diesel Tuning, all you need to know to get

Correct Diesel Tuning, all you need to know to get improved power and economy from your diesel.

Diesel tuning is more important than we think. Lets get down to the basics.

Diesel is distilled crude oil (Distillate). Unlike what most Hollywood movies promote of a diesel truck hitting a wall and exploding like a small nuclear bomb, oil does not readily ignite, particularly a liquid form. If we atomise it though, it will burn readily. The diesel principle relies on air being compressed to approx. 500PSI. This in turn heats the air, turning it into the igniter (diesels don’t have igniters such as spark plugs). Heard of a glow plug? Glow plug only glow on cold start-up to help warm up the air in the combustion chamber. A bit like when you are pumping up a push bike tyre, the pump gets warm.

Ok, so you now have very hot air and you inject diesel in through an atomising injector. As soon as the diesel leaves the injector and enters the extremely hot air the diesel ignites and combustion begins. Put a poor atomising injector in the picture and you have a different story. Because it is not atomising the diesel enough, the fuel volume burns erratically and...
