There is a very bad habit in the world of the engine, and it is to think that all the engines are more or less equal, and therefore may also be conducted in the same way. Unfortunately there is no greater error than to generalize in both the demands on our mechanics, and one of the most widespread in recent times is to believe that circular for the maximum time possible with the needle of the rev counter to a minimum of revolutions allows you to save fuel if drawback any. But what is this technique healthy for our engine? Because I’m very much afraid that in most cases no, and this is why.
The current gearboxes have developments that are too long, forcing the mechanics to work at very low spins
With the arrival of the new standards, anti-pollution, and the need of introducing consumption increasingly low, the manufacturers have imposed a set of rules that speak of engines of low displacement associated with gearboxes of relationships very long. With this approach, you happen to note the cycle of type-approval NEDC is much more simple, but in the real world, this type of solutions require us to know very well where you work comfortable our engine.
An aspect that calls powerfully the attention is the introduction into almost all the modern cars of the so-called recommendation systems of relationship engaged in pursuit of achieving greater efficiency. These systems are based on a few preset parameters, which invite you to change a little bit that the rev counter moves in the first tenders of torque. If we ignore this system, the ratio change occurs, and our car falls of laps, as the system barely knows the actual requirement that provides us with the driving. Driving on flat terrain there are not too many problems, the new engines “turbo” fail to retrieve the flight more or less decent, but when that kind of changes occur on slopes unfavourable, the thing changes and it occurs the effort that we must seek to avoid. With the changes automatically, the problem is not so serious, the electronics knows when something is not going well, reducing one, two or even three gears if we ask for 100% throttle.

Working with very low revolutions have their “good” things, however to do so, by general rule, may be counter-productive by forcing the mechanics to support efforts and vibrations in your worst area of work. The most efficient way to use our mechanics is to know your torque range, the area within which the propeller delivers its maximum moment of force per gram of fuel used. But here again we have a problem, the gearboxes are designed to standardise consumption, not to make the most of that torque available.
Finally, and as expected, play detective and find out what is best for our propellant, estudiándonos torque curve and determine the development of the exchange relations and the jumps that occur between them. Here is the key point to truly reduce consumption by leveraging the maximum torque offered by our propeller. Get used to always working in optimum regime will not be easy, but I assure you that this work really will help to reduce consumption without forcing the mechanics.
Yes, the fly is longer to consume less, as long as it work correctly to the engine
To the end of the day, the best change is one that occurs taking advantage of the maximum of the zone pair prior to proceed to insert a greater relationship. In this way, the engine will work at all times in the zone of maximum torque and thus offering all of their thrust and without waste of fuel have dropped too the rev counter when you insert the top gear ahead of time.
