            A five cylinder has more firing pulses per rotation than 4 and there’s an overlap between them so like one combustion is still finishing while another starts. Idk how or if that improves or corrects imbalance but it reduces vibration and that feels like the same thing.

    >A disadvantage of the odd number of cylinders in a straight-five engine is it results in imperfect primary and secondary engine balance, unlike a straight-six engine which has perfect primary and secondary balance. Counterweights on the crankshaft can be used to reduce the vibrations from these imbalances.

    The real reason i5s don't exist is because they're impossible to carburete with fewer than 5 individual carbs. This made them historically impractical. Since they switched to of fuel injection, companies have still been going with the historical designs because there isn't a reason to reinvent the wheel.

            Two generations of one platform is not the definition of "common". There are only a handful of cars that have ever used it. i5 is literally the least common engine configuration, it is even outnumbered by v10 and v12. And the reason is because they couldn't be easily evenly carbureted.

            Two cylinders can fire at once and it could be too lean for one carb with low CFM. The problem is that adjustment will never allow a carb 5 cylinder to be minimally efficient to a 4 cylinder before fuel injected by rail.

            Finally OP reveals the whole reason why he made the thread. Leaving aside the fact the conclusion of the video is wrong, because it's obviously possible to feed a 5 cylinder with 5 carbs, you also got the wrong conclusion about engine balance because both inline 3 and inline 5's have less secondary vibration than an inline 4 (and an inline 2, obviously).

            I'm the carb guy, I'm not OP. If you refer to my original comment, I said "impossible to carburete with fewer than 5 individual carbs" so you're not disagreeing with anything I've said. I know you can carb an i5 with 5 carbs but that's not practical for a vehicle meant for regular consumers. Your mom doesn't want a car with 5 carbs, she wants a car with one carb per intake manifold. Engines with one carb per cylinder (or one barrel per cylinder in the case of those double/triple carbs) are reserved for enthusiast vehicles where power comes at the cost of complexity. Yet there's no reason to use an i5 for that application in the first place when you can use a i6 or v8. Thus the 5-carbed i5 is practically useless.

            Aren't confusing odd fire engines with engines with an odd number of cylinders? Most econo engines are now 3 cylinders and they hardly sound rough. On the other hand, many early 90° v6 were odd fire and even though they have perfect primary balance from the counterweights (like any vtwin) they sounded and felt rough, as if they were misfiring.

            Mercedes only started making diesel inline 5s because they needed a bigger engine and an inline 6 wouldn't fit, while it would be too expensive to make a brand new v6 compared to simply adding one more cylinder to the existing engine. Audi did it for the same exact reason, as did most other manufacturers

            Yes, let me source 60's german documents. Will a picture of the w115 engine bay with the 5 cylinder om617 do? The w115 had petrol 6 cylinder engines, but they have smaller bore and stroke are obviously lighter than a 6 cylinder version of the om616. Even if you squeezed in a 6 cylinder diesel by fiddling with the radiator and replacing the pulley driven radiator fan it would probably make the front end too heavy.

            You consider this evidence that they would've preferred a 6-cylinder but couldn't make it to fit? How about this, they designed that car and that engine together, if they wanted to fit a 6-cyl they could've easily, but they chose not to. You're wrong, sorry, and there are no German documents to source that would say otherwise because, again, you're wrong.

            How were the car and the engine designed together if the w115 was designed in the 60's and the om617 was designed in the 70's?

            Maybe you were thinking of the w123, which arrived later, and which does have enough room for a 6 cylinder diesel, even though it never got one. Perhaps the turbo diesel version it got made it redundant, but i'm just guessing.
            It took until the w124 and it's brand new engines before mercedes had a car range with a 4, 5 and 6 cylinder engines.

            Why the w126 specifically when it's predecessor, the w116, already used the om617 (and a turbocharged version at that)? But look, you made me look up a technical paper that confirms what i said regarding the om617 and the w115:
            http://www.w124performance.com/docs/mb/other/SAE_OM617.95X_Development.pdf

            Which also makes me point out another quirk of mercedes back then, which was to never make an engine that powers a single car, even the 6.3/600 sel shared it's engine with the 600 limousine.

            Sure is a lot of responding to tone in here. The fact of the matter is that the reason I5s are uncommon is because the majority of manufacturers don't see the point of making one, not because there's some sort of major engineering hurdle involved. It's entirely possible to make an I5 with performance directly between an I4 and I6 today, just like it was 70 years ago.
