Toyota 1zz and his "connecting rod dance"

Hello everyone, I celebrate your participation in this topic, Servilimit. Yes, very much agreed that very important data is missing as you say; MANY BETWEEN Fiat147 and I, we have not wanted to go more ... basically focus Different slack (palpable by hand) in the connecting rod N3, and I warned the client, which would also break ... (I sold it, and I never knew ..) Well, in terms of the speed of the piston, I would like to expose the operation, so that it is corrected, because I have been wrong there: speed embolo = number of revolutions x career x 2, all this divided between 60000 19.52 MX SEG. At 6400rpm for a 91.5 mm race, good, it is very nice that we compata opinion, I encourage all those who want to participate. Greetings!!!

Hello everyone, I join what ismael53 affirms, the pretty of regional opinions and I call atodo who wants to leave his opinion. Personly I think this debate is starting , I never hint at a manufacturer's calculation error when designing the engine. My opinion was that it was an error of Ddiseño requirements (the designer was raised to Tonto, if not, as they say very "alive" and as Ismael says and when the man who pays 17000 Eurasos by a motor racing of a brand that is considered reliable asks the matrix house for a little less than it does , which I do not find serious. It gives the brand after having collective demands or even for loss of lives (electronic butterfly failure of many Toyota USA (2004-2005 approx), where these types did not roam until they were cornered, and called to revision thousands of cars in the USA and Canada, for this problem, but incist only after people died in their cars due to problems that the manufacturer could be proven that the manufacturer could see Correjir in time.

Indeed Fiat147, these "Yankees" wanted an engine that tubed everything ... but power and elasticity in a 1.8cc .. or the one, or the other .. I am going to get with them daring to say that they only know of large engines, from 4000 cc up ... it all goes big, they are engines, buildings, posters, weapons ... all based on money ... PSA Motor 1.4 You, to this engine, in the fit different powers, from 60 hp to 98 hp, well, I think that by 88, they wanted to take out a sports version (famous Peugeot 205 Rally and Citroen Ax Sport), looking 73.2, (theme apart the carburement, etc. ..) resulting in an engine that rises to 6800 standard, with this example I mean that they knew what they did, despite the years, it is still "giving firewood" and this "small 1.3" being effective, these do not break so easy , in short, this can be the origin of the problem .. the birthplace of this 1ZZ ... that they dedicate themselves to do "Harley See how they are given ... , and if they dare, why not? A Crysler F1 Pal 2014 ... and! That the Red-Bull and others are preparing .. Anyway, to see if that day comes !! Greetings !! and sorry for my asshole

Hello everyone, Ismael53, Jaajaj, you have made me laugh with the gringis in F1 ..., a fight of Sellos dogs, to which a chubby with a chela (beer) in his hand is not invited ....
Well, always a taste. With respect to its excellent post in which, it exibates the way several mechanics books use to calculate piston speed and the infleucia of your career in inertia that must handle the engine, all correct, for my point of view, so more people can share phenomena that occur in the engines. It is the way I always use, and I just learned from a buying buying time for a while. I recommend that people have some interest in this download the book, for my masterpiece (in my beginnings and until today). 4 -stroke trick, Miguel de Castro Vicente, in Manuals on this page. Especially in the great sense that this SR has to explain complex phenomena with simple words, for me very recommendable especially to people who have some interest in basic competition issues. The subject of competition, apart from like it, I find it invaluable when seeing it as what is based on technology, as well as being able to make extrapolations to the normal use of a car ... already enlrred me .. , what works in competition usually over time passes to the street cars, if the bug works on the track, usually that man who bought his new car (much effort) without knowing it is more sure to competition ... opinions ... Greetings to all.

Yes sir ... what memories that book brings me !!! And where will it be? Thank you for pointing out that it is on this page, because more than twenty years ago I read it, and I still remember many things from him (I lent him borrowed and ..) very advisable especially those who like "tunning" to see the "burradas" that sell them and then do not work ... well they go against (eg the escapes ..). To say that there was a generation here, in which it was rare not to have read this copy. If I have for there is a sheet with several equations taken from that book, and they are timeless, but I will try to download it (because I am bad of megas ..) In this one you can see that formula to see the speed of the embolo .. and many things of great interest, will help to understand the why of this debate about the 1ZZ .. and well, as Fiat147 says, sometimes, things developed in F1 apply to time. The VVT ​​of Toyota (very good) if the engine cannot or "should not" rise so high, in addition that the cylinder filling is not noticeable in casualties, (a rare but true thing) because "walks the fart." Well, in the commercial plan, that nobody worries, that this 1ZZ is no longer there, but if you have in front, take your eye and ear !!! Greetings!!!
