Exchange of opinions about the F9Q engine

Hello everyone, to whom you know this or other engine of the "celebrities" of Renault ... The case: multitude of cases in this type of motor due to rod semicinetes and subsequent breakage of the motor block (clear ex. Of connecting rod x the side ..), in addition to a multitude of turbo rupture cases due to lack of greasing, if you do not believe that these two problems are related to each other? Well, I have seen, first break Turbo, after a while, it goes on the connect Oil pump, because if they were machining (roughness-tolerance) in dolls, they would have broken much earlier, about 140,000 and some 230,000km fall ... Motors F9Q and K9K, they walk well, but they seem to me "a full", to see what you think or have seen of these "reliability porters" Renault, then they are not the ones that you use in the F1. In the official house, you surely see this = and if they are honest, this other what do you think?

Hello everyone, Ismael53, very interesting the topic you raise. In my opinion as almost all chronic and repetitive problems in these portents And other engines in my opinion is due to more than one cause. First engine design failures, these French wanting to miniaturize and integrate everything, in the design stage take into account factors such as performance and low fuel consumption and cost effective
Second, little experience designing, developing and contracting modern diesel engines of direct injection of a small displacement, and passed they sought help from others that did not do their first Common Rail (Nissan) projects well.
Third haste for quickly getting an engine to a niche market which had quite abandoned.
Fourth, chapuses, as two hard save themselves, put a turbo without liquid refrigeration (motor refrigerant or own circuit) (Ismael correct me if I am wrong please), at least in Latin America, not integrate Turbimer function to the engine control unit (turbo reliability), etc, etc.
Fifth insufficient oil refrigeration.
Putiales used, in some areas they are cheap.
Sixth Sell Complete engines (avoid cannibalization, Desperate spare parts or disharmaduria.
Etc, etc; etc.
I personally do not think it is a problem of technological capacity, in F1 it is more than clear. Sure many have seen this video:

Isamel53 I apopic apopic but I do not stop, I am lovely, and shows that Renult does not have problems with technological capacity Sini others. Sludos to all.

Greetings Fiat147, I referred to that of F1, that they know ... but commercial Renault, the old man, wise as Nissan Mechaniz, when he went to Valladolid, to the Renault plant for a topic of crankshaft, I remind him Oil cooler, "Turbos goodbye", the garret that carries, is not bad, but you have to water well, then the electronic theme is part, with its "clip" and all the eggs that every two by three are failing and they seem to be scheduled to Dred On the road, I always say "it smells like Renault" and my wife asks me, how did you know it was a Renault? What a coincidence !! Anyway in the connecting rod, the celica 1ZZ of 143 hp, also, too, you investigate what they say of this ... ok, those who have Renault will tell me, there are also pendulous mechanics, because yes, a megane came with gripado turbo because they had put a filter of greater diameter ... with which, I was losing ... and almost without pressure, or oil. There are ... greetings !!

hello everyone. ISMAEL53 A pleasure share ideas with you . All brands have their black ear I am toyotero, because of experience I have been able to verify that the japo in general are one step ahead in reliability, the electronics of Red Bull is Nissan (Infinity), perhaps that is why it is reliable, because the magic in the equipment of energetic drinks is Adrian Newey and not Vettel. I would like to see that genius of the modern F1 technique with Alonso (extraordinary quality fighter), however currently in a red pot , but that's another issue.
About Toyota I can tell you that I have personally been printed with the quality of the final product. Toyotas f, 2f, benerable engines that are kept here and people who have them very much appreciated by being 40 years old. and almost half a century, not for soft use, if not for severe use (Landcruiser Fj especially). I see several and at first they did not attract me much, but they taught me a lot of the art of attending a special and old machine . I have seen these engines work for years almost without oil pressure, cracked connecting rods, broken rings, almost no oil irrigation at the top, almost indestructible simply impressive. However, the BJ (Diesel) here with Btores B, 3b (indirect infection) of the same years with chronic cylinder head problems (such as the photo of my profile, restored by me with many difficulties some time ago). And the same manufacturer , Rare No What do you think?

With respect to Redbull-Renault-Nissan F1 Team they are not infallible either, you remember the failure of the alternator that when breaking, dispersed pieces that produced a chain reaction in the engine, which meant the complete destruction of 2 to 3 engines in the 2012 season, you remember those images when the engine suffers a catastrophic failure, in which the connect intensely violent that the connecting rods and pieces come to the plane carbon background, breaking it and touching the surface of the track (c Hispas everywhere), (I imagine the look among the Renault motorists when they observed such a debacle: and the expression of the controllers in Telemetria Not seeing the problem coming. Finally until they later detected the fault. .
Sorry another off topic

For me the Major Internal Combustion Sound McLaren Honda V12 90s. Also the Mata V12 has an amazing sound (F1 Classic)



What do you think?
Kind regards

Hi Fiat, you have made me laugh with the "big-bang" ... well good ... you have to remember, (I hold on the F1) but I always liked the unparalleled Turbo of Renault with their engines ... that was mechanical, and those who wore them were pilots ... and there was not so much electronic "control" ... there were those who drive with rain and were able to "see" 1,500 hp on water ... I don't want to remove merit from today's F1, but for me it is not the same. As for the Toyota, for me it was always the best, and I think it still is, the only thing that surprised me have already been Varior Celica with the 1.8 CV 1.8 engine. With the connecting rod "dancing" greetings !!!
