Toyota 1zz and his "connecting rod dance"

Hello again, although it is so what you say Fiat147, the issue of friction and the pumping effect, take it into account, but I think that rather, the issue of shortening a career to an engine is given according to its use, to explain it better: being the shortest race, the time you need to make a complete turn is less than one with a long race (since the distance is greater in this case, from pmi to the one that determines the speed of the embolo .. and say that, at more speed, greater inertia of the mass of the piston-white set. Suitable for high RPM number, it is the short running engine, both for the shortest turn time (rises faster) and by reduction of inertia and the weight of the connecting rod to be shorter, (it is lower) on the counterpart of this engine, the torque is located at a greater number of rpm, but its power is greater when reaching a greater number of revolutions (greater mixture mixture x minute). I suppose that you know all this, as is why of the engines of 6.8 or 12 cylinders, to the highest number of cylinders, lower speed of embol Fiat147 Get the dimensions of any of these engines and calculate the speed of Embolo ... some may not exceed 15 m/sec. A 16,000 or more rpm ... that is, even less than the 1ZZ, which is from street ... in case of overcoming it that the weight of the materials of these F1 has some inertia of mass, very small compared to what we know (namely what the rods and the pistons are made .. ) well, this topic would give for months ... greetings, and remember that they are only opinions

Hello everyone, Ismael53 of the above all correct, is what happens in the engines. I went to another point, why did the designers look for not as you expose a short race to reduce the speed of the piston, but they did the opposite, a long race of 91.5 mm.? Knowing that they did not have F1 style materials, which were clearly to be inefficient due to the large amount of inertia inside the engine? What were they looking for with this? I do not think that making it less reliable. With respect to the engines of F1 I have gotten many times many times, their dimensions are public info (FIA) and I already like them very much ... with respect to the opinions they are always only that, personal opinions, that in my view, the debate in my view, so I am interested in knowing their own as that of the rest, I am a combination. Greetings to all ..

Hello gentlemen.
Looking I found this debate between two colleagues, practically a monologue, because I see them almost that according to everything and I have made me want to participate, although my specialty is naval machinery, however, in practice all engines are the same in their function.
In the data that is supplied they do not relate caps adjustment, type of lubricant or lubrication pressure, which are important data for the subject. Normally the alloy of the metals of the cap varies according to the revolutions (n), but a calculation error by the manufacturer in that specifically The thing is on that side.
I think that the data that in my opinion are missing to establish a more successful concept of the problem must be clarified.
A note out, there is a calculation error in the piston speed data, for the 6400 rpm this advances 106.6 meters per second.
Luck.
Miguel

Hello everyone, well -bonely to the debate Mr. Servilimit a pleasure always to have the opinion of a colleague with the experience and knowledge that this forum has shown me that you have. I am new here, but I just look for that, share common experiences that we are all sieve to be better in what we do.
With respect to that data are missing, totally agree .. , as well as determine the problem (s) is complex, also. With respect to the calculation, could it if it is kind to tell us how I get to the result? The other although with Ismael (much more experience than me) we agree in many cases, there is nuance, he is more practical and I am more theoretical, and that's what opinions are about to share that this medium allows us. Hopefully there are more people like you like your opinion in this forum. Happy 2014 to all.

Hello everyone, SR Servilimit the debate began roiz, from another topic, (F9K opinions), that Mr. Ismael53 conveniently translated here. Greetings to all.
