Diesel tuning is a lot more essential than we consider. Lets get down to the fundamentals.

Diesel is distilled crude oil (Distillate). Unlike what most Hollywood movies promote of a diesel truck hitting a wall and exploding like a tiny nuclear bomb, oil does not readily ignite, particularly a liquid kind. If we atomise it although, it will burn readily. The diesel principle relies on air getting compressed to approx. 500PSI. This in turn heats the air, turning it into the igniter (diesels do not have igniters such as spark plugs). Heard of a glow plug? Glow plug only glow on cold start-up to assist 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 by way of an atomising injector. As quickly as the diesel leaves the injector and enters the extremely hot air the diesel ignites and combustion begins. Place a poor atomising injector in the image and you have a different story. Simply because it is not atomising the diesel sufficient, the fuel volume burns erratically and slowly as the flame burns by means of the massive droplets of oily fuel. If you were to light up a drum of oil, you would see a equivalent effect of slow burning and smoke. You can picture that by now the timing of the combustion process is also upset. Add decrease injector stress than normal, due to age, and you have the timing of the fuel ignition point altering even much more (injector opening too early). The injectors doing this alone can make a diesel smoky and sluggish. On a cold morning, the combustion is even further retarded due to cold cylinders and cool combustion and you also get hard beginning.

This situation modifications fully with properly set up injectors. Bear in mind the drum of oil? Effectively, if you could fill the drum with a misty vapour of oil and light it up, you would not only get a massive bang but it would be more than within a flash. A great injector sprays fuel out as a mist and the fuel burns rapidly and fairly clean as the droplets are so modest that they burn with a puff! A correctly set injector pressure also means the fuel is being injected at the appropriate time.

Now, the injectors are ideal but the injection pump could be slightly out of tune. Timing has to be set. If it is too early the automobile can smoke and grow to be very diesel noisy and if it is as well late, the car can feel sluggish. Imagine the spray of fuel as a fist about to hit the piston. If it is hit too far just before leading dead centre it would not only hurt your fist and the piston but it would make a louder than standard bang as the two issues hit head on. If the piston had gone previous prime dead centre and was hit, the force of the hit would be going down with the piston so you would have as well tiny

effect on it. So you can see why timing is crucial for maximum hit impact! Other issues require to be checked like the fuel volume delivered by the pump. As well considerably is power but with smoke, also small is low power with definitely NO smoke and just correct is in the middle of smoke and no smoke! There are a couple of more complicated settings on the pump that are checked and adjusted but these are the major ones.

Effectively, there are 6 injectors supplying fuel to the engine (Imagining it getting a six cylinder diesel). Looks like it has no problems obtaining fuel, but what about the essential element that we forgot about, AIR? Nicely...it has to draw the air by way of a maze. Filter, pipes, inlet manifold and a tiny inlet valve. This has to take place in a split second and the piston going down has to do all the sucking. Thats the governing portion of a diesel engines efficiency. Remember a lot more fuel for much more power is just a lot more smoke! So we have to do one thing about the air to hold factors clean. This is where a Turbo technique comes into its personal with Diesel engines. With a large amount of air now available due to the turbo supplying air right to the inlet valve, the piston only has to suck air from there. Lets not overlook that 1 cylinder has a suction stroke many times a second, so these fallacies of air being forced into the engine and blowing heads off with a turbo are only that! Now that we have much more air, the fuel system can be set up according for a lot more energy. [WARNING- This is where the entire equation can come adrift with overheating and so on. Items have to be set up by a specialist and a specialist that knows his JOB!]

1 final note the diesel program that is on all 4WD diesels was made to run on a fuel with specific burning qualities. We don't look to be getting fuel in Australia meeting all these specifications. We have new cars smoking that naturally are not made to smoke when running on real diesel. So when setting up a fuel injection technique for tuning we have to take the burning traits of this poor diesel into consideration. Attempt to get your fuel from a trustworthy and 'known brand' garage and maintain your receipts. If you have troubles, you then have as much 'come-back' on the fuel garage as you have with a faulty item from a shop.

The modern day diesel has come a lengthy way from its beginnings!! Wellso we are all lead to think!! Thats where it all stops. In truth about the only thing that could compare is reinventing the round wheel!! Thats right. Nothing has genuinely changed. A diesel nevertheless needs fuel and air. Even even though we now have trendy issues like Typical-rail Higher Stress Injection and Electronics controlling everything, it is nevertheless the exact same old principle. The only main change seems to be the repair fees as usual. Most higher tech injectors now expense over $2000 each and are throw away. Most Injector pumps are becoming throw away at about $6500. Exactly where will it end?? try auto engines
