Appropriate Diesel Tuning, all that's necessary to learn to get improved energy and economy out of your diesel.

Diesel tuning is more important than we think. Lets get all the way down to the fundamentals.

Diesel is distilled crude oil (Distillate). Unlike what most Hollywood films promote of a diesel truck hitting a wall and exploding like a purchase here small nuclear bomb, gas does not easily ignite, especially a liquid form. If we atomise it though, it'll burn quickly. The diesel theory depends on air being compressed to approx. 500PSI. Therefore heats the air, turning it into the igniter (diesels don't have igniters such as for instance spark plugs). Heard about a spark plug? Glow plug only glow on cold start-up to help warm up the air in the combustion chamber. Somewhat like when you're moving up a push bicycle tyre, the pump gets hot.

Ok, so you are in possession of hot air and diesel is injected by you in through an injector. When the diesel leaves the injector and enters the excessively hot air the diesel ignites and combustion begins. Set an undesirable atomising injector in the image and you have a different story. Because it isn't atomising the diesel enough, the fuel amount burns occasionally and slowly whilst the flame burns through the large droplets of oily fuel. You'd view a similar effect of smoke and slow burning, if you were to illuminate a drum of gas. You are able to imagine that chances are the timing of the combustion process is also disappointed. Increase lower injector force than normal, on account of age, and you've the time of the fuel ignition point changing a lot more (injector starting too early). The injectors doing this alone can make a diesel slow and smoky. On a cold morning, the combustion is further retarded due to cool combustion and cold cylinders and in addition you get hard starting.

This scenario changes completely with precisely create injectors. Remember the drum of oil? Well, if you could fill the drum with a vapour of oil and light it up, you'd not only get a big hammer but it would be over inside a flash. A good injector sprays fuel out as the fuel and a mist burns fast and relatively clean because the drops are so small they burn using a puff! A precisely set injector pressure does mean the energy has been inserted at the correct time.

Now, the injectors are excellent but the injection pump might be somewhat out-of tune. Time needs to be established. The vehicle can feel sluggish, if it is too early the vehicle can smoke and become very diesel loud and if it's too late. Imagine the spray of fuel being a fist planning to strike the piston. If it's hit too far before top dead centre it would not just hurt your fist and the piston but since the two things hit at once it would produce a louder than usual bang. When the piston had opted past top dead centre and was hit, the power of the hit would be taking place with all the piston so you would have not enough

Affect it. Why timing is crucial for maximum strike result to help you see! Other items need to be examined like the gas amount provided from the pump. Too much is power but with smoke, too little is low power with positively NO smoke and just right is in the middle of smoke and no smoke! There are a number of more complicated settings on the pump that are examined and adjusted but these are the key types.

Well, you'll find 6 injectors delivering gas to the engine (Imagining it being a cylinder diesel). Seems like it's no problems getting fuel, but what about the crucial part that we forgot about, AIR? Well...it needs to bring the air by way of a labyrinth. Filter, pipes, inlet manifold and a tiny inlet valve. This has to take place in a moment and the piston taking place has to complete all of the drawing. Thats the ruling element of a diesel engines performance. For more power is just more smoke remember more fuel! So we have to do anything about the air to keep things clean. That is the place where a Turbo process has its own with Diesel engines. With a large amount of air now available because of the turbo delivering air right for the inlet valve, the piston only has to suck air from there. Lets not forget that 1 cylinder includes a suction stroke many times a second, so these misconceptions of air being forced into the engine and blowing heads off with a turbo are only that! Since we have more air, the fuel system might be set up according for more energy. [WARNING- This is where the entire situation can come adrift with overheating and so forth. Things need to be set up by a professional and a that knows his JOB!]

One last note; the diesel system that's on all 4WD diesels was made to work on a gas with specific burning characteristics. We don't seem to be getting gas in Australia meeting all these needs. We've new vehicles smoking that obviously are not designed to smoke when working on diesel. Then when setting up a injection system for tuning we have to simply take the burning characteristics of the poor diesel under consideration. Attempt to get your energy from a reliable and 'known brand' storage and keep your bills. If you've difficulties, you then have just as much 'come-back' on the energy storage as you have with a faulty product from the shop.

Safe 4WDriving,

The Diesel Experts

The current diesel has come quite a distance from its beginnings!! Wellso we're all bring about believe!! Thats where it all stops. In reality about the only thing that may compare is reinventing the round wheel!! Thats right. Nothing has really changed. A diesel still requires fuel and air. It is still the same old rule, even though we now have stylish things like Electronics controlling anything and Common-rail Questionable Injection. The only real significant change seems to be the repair costs as usual. Most high-tech injectors now charge over $2000 each and are discard. Many Injector pumps have become discard at around $6500. Where does it end??
