I have an Inline 6 in my BMW, great engines. Has 181,000 miles and still very smooth and strong. Nothing wrong with the motor at all. Decent gas mileage and the power is pretty good.

I6 engines generally last much longer because of their lack of vibrations and inherent balance. I have a 2000 Ford Falcon AU (big Australian sedan) with a 4.0 I6 and the engines genuinely last forever. I have seen ex-taxi examples with over 1,500,000 KM (1 million miles) that have had nothing but oil changes and zero engine work carried out! My friend has one with 960,000km on it and again that engine has only had oil/filter and coolant changes and no other work

[@alejandrochavarria4394]

my jeep wrangler 1994 has 187k miles, 4.0 liter straight six, running great

[@Mensaje22]

All 6 cylinder cars will last a long time if maintained and serviced

[@Liam8488]

Both my Dodge Ram and Plymouth Valiant have the Chrysler slant-six, which is like an inline six but on like a 45 degree angle. Lowers the CG and profile of the hood. Great engines man, they both run smoothly and barely require any maintenance. The Plymouth is 50 years old and the Ram is over 30 now

[@soaringvulture]

Slant sixes run forever and are smooth as glass; can't even hear it running. And you can work on them. I changed the starter in my wife's Valiant over a lunch break and even had time for lunch.

[@saablazer]

I've got an inline 6 in my 06 Saab 9-7x. Smoothest engine I've ever driven. if it weren't for the tachometer i wouldn't be able to tell if it's running sometimes.

[@QiruiFan]

Here's my understanding of all the force balancing: First, the actual "force" exerted on the engine could be calculated by taking the second derivative of the piston position function, which is a bit messy and involves some sine function and square root. It could be approximated by a function of A*sin(wt)+B*sin(2wt), where w is the angular speed and A and B are constants, 2wt naturally represents the doubled frequency (shown in his previous videos). The first term represents the primary force balance, and the second term represents the secondary force balance (we can ignore higher order imbalances). For I4 cylinders, the balance will be [A*sin(wt)+B*sin(2wt)] + [A*sin(w(t+pi))+B*sin(2w(t+pi))], so that the primary forces cancel out, but the second force remain (a useful equatin for the calculation is: sin(a)+sin(b)=2*sin(1/2*(a+b))*cos(1/2*(a-b))) For I6 cylinders, the balance will be [A*sin(wt)+B*sin(2wt)] + [A*sin(w(t+2/3*pi))+B*sin(2w(t+2/3*pi))] + [A*sin(w(t+4/3*pi))+B*sin(2w(t+4/3*pi))], the sum of which is always zero. Therefore it's always a perfect balance.

[@emsg2009]

Now I know why my BMW M54 is soooooo smooth . Thanks

[@PoorManMods]

i love my 1JZ! And this video helped me understand why my 1jz with solid motor mounts produces less vibration than my QR25DE (Cyl) with rubber mounts

[@andrewmartinez42]

My 1968 ford mustang had a straight six in it and was pretty quick. Engine swaps with a straight six are far more easier then V-style engines. Good video as always!

[@mcanderson0]

It would be nice to show the geometry behind why “S/2” occurs, kinda like you did in your secondary imbalance video. Its intuitive to understand why the primary imbalances cancel out, but it is not intuitive as to why the secondary imbalances cancel out.

[@GiovanniEsposito5]

Actually, the manufacturing cost fot the I6 can be higher than V6 of similar displacement, because the longer block is more difficult to manufacture than two shorter blocks and in some case more expensive. That's the same for head, shafts and many other parts... .

[@kentmackey2717]

[@davidmitchell5638]

the only disadvantage you must remove is: not good for FWD. i think that's awesome we don't need great engines in FWD!!

[@EngineeringExplained]

As much as I'd like to agree, FWD is a very safe setup, good for poor weather conditions, and for the general public just fine.

[@davidmitchell5638]

Engineering Explained that's why we have AWD with BMW xdrive??

[@Iunio92]

David MuscleGuy AWD does provide greater traction under certain conditions, but along with that it is: Heavy (bad for fuel consumption) Expensive (more parts) Complex (more can go wrong) in almost every 4WD application a FWD car is more than adequate... a lot of entry level SUVs are FWD because people like the image of a 4WD car but will never actually use their vehicles in a situation that requires it. the amount of enormous 4WD cars I see in the city that will never see any more off road action than a regular dirt road (if that) is alarming to say the least.

[@ka24det28]

[@easyadventurer]

Would you say that it's also good for turbocharged applications? intake side > combustion > exhaust > Turbo -- repeat. I'm no engineer but I certainly think it's a fantastic layout for turbos.

[@johnnewchannel6505]

Great vid. I would also mention in advantages that it keeps the mass in the middle of the car, allowing for better handing balance as well.

I know that the I6 and V12 are naturally balanced, but what about the VR6? And a video on the I5 would be interesting.

[@Away907]

VR6 at some degree has all advantages of I6 and mitigates some of it's disadvantages: its more rigid, since block is shorter and wider that traditional I-6 and is short enough to be installed s transverse

[@bobmigarski283]

most important advantage is sound vs the v6, i6 is more throaty while v6 more closely resembles a kid raging at call of duty

[@ThestrokeblogSite]

Very good video. I wish you could make a video about "duke" engines. Is the technology dead or sold to big manufacturers? All the videos about it are from 2012

[@darcybowyer5743]

I have a Tickford tuned I6 (known as the MPEFI EEC IV I6 by Ford) and it's one smooth torquey motor. Only need to shift gears at 2,000rpm or 3,500 if you're pushing it with extreme dependability. As the Falcon was designed for the 302/351 V8 it fits quite nice in the engine bay with later engines using the Borg Warner / Tremec T5 5 speed trans. Can't bloody kill the things either even if you tried, I had my local engine builder telling me he comfortably makes 600+HP on the stock bottom end! Ford later added dual VVT with 4 valves per cylinder in the last "Barra" series with up to 270kw with a turbo!

[@Saadane_fdgod]

[@edgartavares2353]

I love your videos and I'm a big fan thank you so much for what you do. What i would like to know is what determines firing order? Why is cylinder six not firing simultaneously or right after cylinder one since they are both at tdc at the same time?

[@caricatureparty]

I love your channel and really appreciate these videos immensely, but I'm having trouble grasping how the secondary forces balance out, and this video is frustrating to me because every time you say "the big thing you need to understand" I think the key point that I don't yet grasp is coming, but then you say "is that the forces balance out." car and engineeringwise, though, I'm mentally impaired, but I love what you do and I'll keep watching these vids. Thank you.

[@EngineeringExplained]

aaron philby Basically all of the six pistons are split into three groups. There are three pairs of two pistons which are vertically in the same location (though not necessarily horizontally) at any given time. Because of this, and the 120 degree of separation between each pair of pistons, all of the forces are balanced vertically. For example, two pistons might be at TDC, two may be on their way down, and two may be on their way up. The two at the top are temporarily stopped, where the other four balance each other out.

Very precise and apt description for every video your's. Doing a very good job. Highly appreciate it. So this means that I6's don't use balancing shafts or rubber isolaters? Could you please even explain about I5.

Wish Ford would bring back the 300 I6. My friend had a F150 from '91 with the 300 I6 that had over 400,000 miles on it when he sold it 4 years ago. It's still going strong 'till this day. Can't beat I6 engines; there's a reason most semi trucks have them.

[@arnedorr6904]

Thank you for the video it is very informative as well as all of your contributions! Notwithstanding I have a question concerning the compensation of primary and secondary forces: You said that the momentum of pipstons no. 1 and 6 would be compensated by the sum of the forces of pistons 2-5. Purely numerical this makes sense but as we talk about forces, we have to bear in mind that their physical nature is actually directed! This means that the forces of pistons 3 and 4 are pointing downwards and the ones of 2 and 5 point upwards. Pistons 1 and 6 are actually not even moving in the crankshaftposition you suggested in the sketch beneath (direction of force?? no idea). According to a certain convention of signs (for example upwards means negative and downwards positive), the calculation "P-(4xP/2)+P does not equal zero anymore. It would now be: P+[2*(-P/)+2*P/2]+P and this comes out to be 2P, thus not inherently balanced. If I am completely messing up something, please advise me but in some way I think we have to consider the direction of forces. In fact, pistons that are situated before TDC can't even move downwards as presented in the sketch!? Sorry for the confusion but I'm pretty stuck with this :/

[@simonlovell227]

You're confusing velocity with acceleration. Acceleration is proportional to force. So at TDC, primary forces are indeed at maximum and when cylinders 1&6 are at TDC, cyl2-5 do indeed have 50% of max primary force in the opposite direction.

[@icsbay7932]

Hi Jason, great insight and knowledge! I have a question: I'm currently building a sporty/streetable BMW M20, (86mm bore) and I'm deliberating whether to use a 76mm stroke crankshaft and 135mm long con rods vs 81mm crankshaft and 130mm con rods The question is, is the increased overturning/tilting moment, generated by the shorter con rods in combination with the bigger stroke, creating a friction that's so big that it counteracts the gains by the increased capacity to such extent, it's not worth it increasing the stroke?

Thanks I had all ways wondered why my BMWs 6 cyl engine was so smooth compared to a Peugeot v6

[@gwalia2112]

The old 2.8 Nissan was a lovely sounding diesel engine in both turbo and non. A slow engine but capable of towing well in the Nissan Patrol, slowly though, and huge mileage possible with these. Sounded much nicer but ultimately not as good as the 3l 4cyl that replaced it.

[@abhishekshashidhar2038]

how do you control or set the firing order? and is there any other firing order which might balance the forces in engine?

[@simonlovell227]

One thing I don't understand is why the i4 is so popular for light diesel trucks, with displacements in some cases over 5L. Is it just saving a small amount of $ is worth the vibration? I guess so.

[@darkhelmet951]

I'm surprised you didn't mention Jeep, the 4.0 L (242 cu in) was the most popular straight 6 engine out there.

+Hunter Ziegelmann Can't forget Ford's inlines like the 300 that ford used in trucks forever.

[@Clickmaster5k]

Ya if you consider the linage of the 4.0 its might have been one of the longest produced engine designs. The 4.0 was derived from the AMC258 that can be traced back to the original design in 1964 as the AMC 232. This engine design was used in various forms from 1964-2006.

Ummm what the about the group A -GT500 RB26/RB28/RB30 engines? All do respect to the 2jz that is a really great engine I feel the RB26 is a lot more tuning friendly or even the rarest inline six Nismo's GT500 RRR block?

[@Striball]

I think he was just name off a few (2) to give examples. If you're a little 'fluent' in cars then you'd also probably associate the RB series along with the group as he was naming them. He isn't necessarily saying this or this is better than this, just broadly explaining the engine, because that would possibly create tension between brand loyal fans, engines, etc. Just the broad definition. By all means the RB, JZ, and the N/S/M 6 engines are wonderful engines, respectfully.

[@NismoDre410]

Agreed!

[@brenanporter4003]

Niall Horan for real. I don't think that many people know about the BMW straight six. the 2jz and the rb26 are for sure the most well known straights six engines to car guys (or girls).

[@Nidhichirania02]

I am stuck with one thing that- As Google says 'The firing order is the sequence of power delivery of each cylinder .' According to you, the firing order is 153624, but as 1st and 6th cylinder move simultaneously, they both complete compression stroke at the same time and therefore they must provide power at the same time. Then why the firing order is not 16......?? Looking forward to getting a reply. Thanking you in advance.

[@emirb.a.745d7]

Hello , well no , two pistons that mvoe together can't have a power stroke together , only one is permitted , this is due to the firing intervall and the need to guarantee a n even power distrubution along the crank shaft, since we're talkign about 4 stroke engines here , the cycle repeats it self every 720° , however if the example was a straight six two stroke engine , then your proposition is correct. ( even tho it's not a good idea considering the application of two simulantous forces on a same crankshaft would require it to eb stronger therefore heavier , another reason why two wasn't so common in a numerous cylinders engine... ).

[@brfsa]

Is crank length ever an issue? or will the con rods always fail before the crank. for science of course.......

[@charlesvan13]

The straight-6 seems to have lost out to the V layout, V8 in particular, in America. A friend bought a '70 Dodge with a IL6. It was slow, being the base "economy" engine, and had a tiny 1 venturi carburetor. But it sucked, because it got the same gas mileage as the V8 69 Mustang I had that could go 50 mph in first gear.

For example, in Formula 1 they were considering going to inline fours, but Ferrari opposed because they wanted to be able to have the engine as a stressed member of the chassis, and V engines are better for this.

[@linzc3033]

Depends on the engine design, but many i6 engine have a main bearing between each piston, that's 7 in all. V engine normally have 2 pistons between each main bearing, so for a v6 that is 4 and for a v8 that is 5 in total. Those extra bearings increases rigidity and strength of the crank significantly in an i6. Yes the crank is longer, but the force applied to each bearing is lower.

[@ibang3586]

Good Work! Congratulations! I have a doubt though. Shouldn't have the opposite direction the primary forces associated with the 2nd and 5th pistons? I mean, both pistons are going up, while 3rd and 4th pistons are going down. Why could their primary forces have the same direction. I'm sure I'm missing something. Could you explain it to me?

[@ibang3586]

I've just understood looking the drawing more carefully. Forget my question.

[@xtremevarunismyname]

Hey! i like your videos very much! Can you please do a video explaining a 6 - stroke engine?? Please?

[@elainelorimer818]

[@javierdelgado1346]

My e46 M54 engine is extremely smooth with almost 0 vibration in the cabin.

[@AR-ob7nl]

+Javier Delgado The M54 engines are golden! Not only are they extremely smooth, but they're fairly powerful and have a wide torque band. They're also extremely reliable. As long you maintain them, they'll easily go 200k+ miles. I have an E39 530i and an E46 330Ci, both 5-speeds, and love them to death!

[@kundankhareprs]

Could anyone explain that how to decide the direction of secondary force?

[@CarsnStuff]

Inline six engines are among my favorite engine configurations of all time. Though that seems probably biased since im a supra owner. Before i ever obtained my supra i grew up around my moms 86 landcruiser which was also an inline 6. There is a unique torque output that only an inline 6 can produce. The way i like to put it is if you were to take a 4-500 hp car and face it against the exact same power output car with an inline six. i can assure you the inline six will feel much more exciting. Whether or not its faster is a different factor. But its all about the driving experience and i think the I-6 delivers that perfectly.

it is but it's laid on its side. some argue it's a problem because over time the gravity can actually warp the pistons the more miles put on.

Would this be the same for an inline 4 Cylinder engine as well?

[@suprafabb]

You mentioned rigidity as a disadvantage. Can you give me an example of this disadvantage in a real life scenario? Thanks

[@EngineeringExplained]

Formula 1 chose to go with V engines rather than inline so they could use the engines as a stressed member of the chassis.
