'Ηigh Precision Injection

Now BMW is moving up to the next level of technology at the 2005 Frankfurt Motor Show: Introducing a breakthrough technology for lean direct injection
of gasoline referred to as High Precision Injection, BMW is setting out to solve the conflict of interests in the next few years between sporting performance and superior fuel economy, moving up to a standard of excellence never seen before. Indeed, High Precision Injection will save up to 10 per cent fuel in the European test cycle and between 5 and 15 per cent under typical customer driving conditions, depending on the route taken and the driver’s style of motoring, over and above BMW’s VALVETRONIC engines already renowned for their outstanding efficiency. High Precision Injection therefore for the
first time offers the full thermodynamic potential direct gasoline injection is able to provide.

So far direct gasoline injection systems have not been able in practice to provide the advantages in fuel economy originally anticipated. The first technical solutions were therefore completely unable to fulfil the demands made by BMW’s engineers, which is why in 2001 BMW launched an alternative technology for optimum fuel economy, the Company’s throttle-free VALVETRONIC engine load control concept, as a standard technology featured on BMW cars. Proven hundreds of thousands of times in the meantime and now featured worldwide throughout BMW’s entire range of models, VALVETRONIC has definitely turned out to be a lasting,
sustainable solution.
At the same time BMW has continued to focus carefully and consistently on the development of direct gasoline injection – especially because it was always known that direct gasoline injection had the potential to offer even greater benefits than all alternative technologies.
BMW is therefore now becoming the first car maker in the world to offer
High Precision Injection as a solution appropriate for large-scale production saving fuel to an extent in practice simply unparalleled by other technologies.
A particularly important new feature is that BMW’s High Precision Injection
no longer requires a specific flow of fuel and air in the combustion chamber to provide the right mixture. Rather, BMW’s engineers are able to prepare the appropriate mixture by means of a stable, conical configuration of the injection jet entering the combustion chamber, the fuel/air mixture then igniting
directly in the area of the injection jet. Precisely this is why experts refer to this technology as jet-guided direct injection as opposed to air- or wall-guided injection.
The injection valve configured as a piezo-injector and positioned in the middle between the valves and the spark plug also at the centre of the combustion chamber represented a challenge in the past simply insurmountable,
since both temperatures and pressure levels were too high above all within
the cylinder head with its confined space.
Now the reward for the great efforts made by BMW’s engineers is a very robust combustion process functioning efficiently throughout a wide operating range and therefore far superior to former solutions in the market. Hence,
the engine is now able to run on a lean mixture all the way from idle speed to high revs, maintaining a surplus share of air at all times. And precisely this gives the customer significant benefits in terms of fuel economy, marking the big difference between BMW’s solution and other concepts in the market allowing lean burn operation only within a small “window”.

A further advantage is that High Precision Injection does not call for any compromises in the design of the cylinder head and pistons depriving the car and the driver of the high level of maximum torque and output so typical
of BMW.
Introducing High Precision Injection, BMW is therefore once again proving the Company’s leadership in drive technology – especially because it is BMW’s philosophy not to introduce innovations merely as a purpose of their own, but rather only when such innovations are appropriate for the brand and therefore offer genuine customer benefits.
BMW High Precision Injection will first be launched in the European markets. Then, with sulphur-free fuel becoming increasingly available as the
essential ingredient for this engine with its NOx catalysts, High Precision Injection will also be introduced in other markets one after the other.'

Είπα κι εγω...χωρίς μαγικό πως τα βρήκε?!

Ένα κλασσικό λάθος είναι να ψάχνεις κάτι απλό και να έχεις βάλει ελληνικούς χαρακτήρες. πχ στο συγκεκριμένο έβαλα M50 BMW αν έβαζα Μ50 ΒΜW δε θα έβγαζε τίποτα επειδή τα γράμματα με μπλέ είναι ελληνικοί χαρακτήρες.

Απλό μεν αλλά εύκολα μπορεί κάποιος να ξεχαστεί και να παιδεύεται άδικα.

Tι ειναι τούτο;

μπορει να μου πει καποιος αν ειναι ευκολο τα specs του κινητηρα Μ40 σε μοντελο του 89 διοτι αλλου βλεπω να λενε 113 αλλου 122 θα θελα αν γινεται οσο πιο αξιοπιστα specs.α καλη αρχη και απο μενα για το φορουμ
