Your ability to ferret up a fascinating topic is almost as enchanting as your videos themselves. And I was convinced from so far away you would leave out the 8V71. I will learn in time.
@@j.m.5995 yeah got them in my mk2 jetta but they are not even close to these on the vid when it comes to how wobbly they are. Probably that is because of their lenght, no pulleys, tensioners just a long free space for them to wobble about.
On those North American Detroit powered buses, the belts are tensioned from a compressed air cylinder, that doesn’t extend until the brake reservoir pressure is nearly full. It makes replacing belts on the road super easy, but cold starts with low air are interesting.
My favoirite Detroit is the Series 50, which a 4 cylinder and 4 stroke diesel, what used in some Hungarian made Ikarus buses, for example the most of the type of C56, 256.42 & .22, and some of the E95s
Interesting video! A brief story....I'm a doctor in Primary Health Care in Greece. From 2008 till 2010 I was working in a Health Center in central Greece, that had in use two ambulances. A Fiat Ducato 1900 , that did....what it could and a VW Transporter VR6, manual transmission...the "good" version. Legend (and drivers) say that a couple of years before, they went to Athens' main Pediatric Hospital, transporting a child in critical condition, proceeding , when it was possible , around 200 km/h....continously and for long distance....without any minimum problem.
1:30 Thanks for sharing a turkish plated O303 V8. These machines are so iconic here. Every petrolhead appreciates its sound. So sad the time of the OM400 series has passed 😔
What I love most about this channel is it's not biased towards supercars and high performance engines. It's literally an ever expanding encyclopedia of all things engine! Love it
Superb sounding motors, particularly the OM303 near the beginning of the feature. The 'steam horse' in the NYMR bus/truck is a low pressure double expansion unit.
As a Busdriver I was very pleased to watch this. I took my licence in a 2000 Setra 411 mated to an OM501 LA v6 and a 6 speed manual gearbox. Now I'm stuck driving a Scania Citywide with a CNG engine. Which I should ask, next topic? Worst sounding bus engines?
Now THESE are exactly the sort of engines I'm most interested in. I wanted to be a bus/truck driver when I was a kid, too - and decades later I still often do. Amazing video, left me with plenty of new things to look into further.
@@isaacsrandomvideos667 Yeah it was a cool modern design just like the GMC RTS- a transit bus that was built from like 1979-85, but looked like it belonged in the 90s.
You mean the blower driven top end of a 2 stroke ie: a 12v71? Thats not a supercharger its a gear driven blower to get air into the engine as large 2 strokes have trouble breathing. It doesnt actually run boost, so technically Theyre naturally aspirated
@@billyray4716 It's still a supercharger, boost is just the rate in which it pulls air. 1psi or 30psi, it's an airpump, a compressor, it has boost. The name "supercharger" is just popular nomenclature coined when people started pulling those blowers off those diesels and putting them on their hotrods. Supercharger technically isn't even the correct term for any of them, it's just what they're called, like how all toaster pastries are called Pop-Tarts. Roots or twin screw blower or compressor is the correct term, some car review mags and blogs will even say this in the specs, as it is proper. One could argue every supercharger isn't a supercharger, but nearly all of them are used for performance gains- not in the way we think of performance today, but yet still to increase engine performance in pulling more air whether it was for better fuel mixture in the detroit, or so a fighter plane could reach the clouds. They were also used as emissions devices; Fords thermactor by todays standards would be called a tiny centrifugal "supercharger", despite any kind of performance was not it's purpose, and if I recall, it blew air straight in to the exhaust manifold. Same with the "supercharged" Toyota Previa; it's blower was for emissions compliance.
@@ItsDaJax These two-stroke diesels literally do not run without the blower on top, it isn't a power-adder, its crucial to the engines operation. Unlike the usual sort of two-stroke you'd find in a dirtbike, where the combustion chamber is cleared by the fuel-air charge being pushed by the bottom of the piston out of the crankcase, the bottom end of these diesel two-strokes is much like a four-stroke bottom end, there is no port to the cylinder, its full of oil, and it doesn't have a fuel-air mixture inside it. To clear the cylinder at the bottom of the power-stroke, remember, as a two-stroke, there is no exhaust stroke, the blower - true to its name - literally blows the burnt exhaust out and fresh air in. It doesn't really produce any appreciable boost as it does this though, its simply there as a matter of "this is how this engine runs".
i love when i walk to school and get passed by my local busses they sound so good and in the winter i usualy wonna go skiing so i take the bus to the lifts and i can just enjoy the turbo from inside the bus
I remember the legendary sound of the Mercedes Benz O303, yeah it's V10. It is the only bus in region. It was active every week from Monday until Friday until the pandemic started on March 2020 & since then, it's parked not far away from my house (private bus company's garage).
I have done some mechanical work om MAN buses with Mercedes V8, its insanely tight to work on them in a bus. Once I changed a head gasket, we had to be 2 persons to do the right torque!
Nice video! I work in a buscompany in north Germany. I remember we had a bunch of Mercedes v8s from the 80s. They had so much torque and the sound was delicious.
In Argentina, several coaches runned aircooled V10 Deutz engines. Also urban buses equiped BF6L Deutz. Incredible soundtrack of the 90s. Great video, and greetings from 🇦🇷 once again!
I used to love buses so much when i was kid. I'm happy to see my favorite yt channel talks about buses for the first time. Ya see such boring comercial vehicles can make a good sounds too
I love commercial vehicles. The megaliner is my favorite coach, GMC RTS is my favorite transit bus, International Harvester 3700 series are my favorite school bus.
Of course you're not the only one. Sound is, in many cases, one of the key characteristics that make a certain bus interesting. A large number of bus enthusiasts will tell you that. Therefore, you just keep on enjoying those sounds. :D
You definitely are not! A lot of things get archived, but do enough sounds get preserved? If a sound gets embedded so deeply in our memories it must mean something
In the Philippines - Nissan Diesel truck based Condors are once commonly used esp with CPB with FE6B NA & SP215/PKB 212 with FE6C. When the resonator removed the engine growls very loud....
Love the video 👍 love the sound of the Detroit diesels the buses, in ireland used them in the 80s to the early 00s. Missed the sound of these engine's....
They were used in everything. Military Humvees used them for a while, before they were replaced with Duramaxes, like the H1 used throughout its run. I think Seagrave used them in fire engines until the 00s. Little known fact about Seagrave, is it used to be the FWD truck company in the early 1900s. I think Seagrave uses International Harvester or Catapilar diesels, and they are slower than the detroit trucks 0-40mph.
The Mercedes O303 is childhood memory. Before turning 20 years old I surrounded the earth twice in these things - fair to say I never sat in one afterwards. Not only because I had a car but also because they were old and disappeared from German roads around that time. Except for the odd Neoplan or Setra (which usually had the same engine type) all bus companies in the area I grew up had O303 coaches. I went on several school class trips, 4 times from the middle of Germany to Florence in Italy on school concert trips, countless day trips and as there was a version for rural line operation as well (called the O303 KHP-L) and Germany uses regular revenue buses as school buses, an O303 happend to be my usual school bus, adding the majority with 35 kilometers each school day for 6 years to the total. And of course I would sit in the back most of the time to hear the engine.
Pretty cool video. As a kid I dreamt to be like Ascari or Fangio. I appreciated an old Greyhound bus in my later years powered by a V8 Detroit Diesel 2 stroke that absolutely screamed beautiful noise. I did some external sheetmetal work on that one.
This was cool to watch being the owner of a bus company myself. Those scania F series buses are brilliant. We get awesome fuel mileage from it and the motor is a power house.
The tickover of the Mercedes OM604LA is something I always loved. Would have been used in the Vario and Atego. I believe I have the engine code correct.
@@TheKnobCalledTone. IMO, the MAN NL 202's with ZF 5HP 500's or Renk Doromat 874's (search for "NL 202 NE-TH 5200" or "NL 202 WES-JA 58", these are their registries) sound the best for me. ;)
If you were to ever make a part too, I'd suggest the leyland 0680 found in Bristol REs, Cummins 8.3 found in dennis tridents 2s, volvo b10ms (or any BUs with the D10A, TD102KF or whatever it was ), Dennis dart with the cummins 5.9, scania N112/3s and any bus with the gardner 6LXB..those are good sounding buses too
Thinking back to going to school in a 1947 Ford rear engine transit bus, overloaded with standees. This 95HP flathead V-8 would somehow climb a steep bridge over railroad tracks on the way.
I'm a bus spotter, it was great to see a video about buses here! There's a lot to know - and hear - about buses, the Scania DC9 was a great surprise among other great engines listed in this video. Some examples that could be shown in another one: Scania DSC11 (Scania F113HL, K113CL/TL, L113CL and other 113 models), Volvo horizontal 10 litre series (Volvo B10M range, like TH102KF) and 12 litre DH12 (Volvo B12M and B12B TX platform), Mercedes-Benz OM449/MAN D2865, Mercedes-Benz OM366/366A (turbo)/366LA (turbo intercooler), Cummins ISL (Volkswagen 18.330OT), MAN D0836 (Volkswagen 17.260OD/ODS, and other VWCO models), Cummins 6CTAA 8.3 (look for Mafersa, a public Brazilian company that built trains and buses through 1980's to 1999's, model name M210 Turbo), and the list goes on! You'll gonna love them.
I worked on U.S Army vehicles that were powered by a 8v71 Detriot Diesel.That vehicle had both a Roots supercharger and a Turbocharger.Needed the turbocharger because of the layout of the air intake system.Made for a fun time servicing the engine though.
For me the best sounding bus engines were the mack maxidine used in Portugal in the seventies. The engine was so powerful that the bus just used five speeds, being faster and more powerful than the others. And when accelerated, it produced a strong but pleasant hiss. It was able to get a speed of 50mph (80km/h) in a 10% incline and had a top speed of 85mph ( about 140 km/h).
I've been on the steam bus at Whitby in England. The video doesn't show the gradient of that hill too well, the way it goes up is amazing, so much torque, it leaves modern vehicles standing
Greets from Indonesia... I am one of the bus enthusiast from East Java... Those engines are undoubtly is marvelous👍 But here, the old ones especially the front engine type one (engine located beside the driver) has the unique sound of the engine and a superbly marvelous exhaust sound at the back of the bus... The new ones, not having that sound 😂
I wish Automotive Industry do a couple things: *Never give up on Internal Combustion Engines. *Improve its ICE, at least 50% as efficient as you're improving your great work!!. Many thanks & Blessings!. 😊🙏🙏🙏
Honourable mention: Hino AK1j bus (J08C engine) 4 stroke 7961cc Inline 6 diesel Can hit above 3000rpm, when revved with a straight pipe exhaust, it actually sounds like a giant M3 E46
There's nothing that compares to sitting in the back seat of a bus powered by a Detroit 😊 Especially if it's mated to an Allison AT545 transmission 🥰 Boy, the two of them could sing a song 😁
I love watching you're videos Visio racer. They never get boring and you continue to surprise me with the quality of your work, this video was very fascinating!! Keep up the great work 😃
90's babies in the US, the best sounding bus engine for us was the T444E then the VT365. Something about smelling the spent diesel on a cool fall morning.
I like the sound of the Volvo B12B Alfa Regio. It's have a Volvo DH12 Inline-6 engine, which is have a pretty amazing sound. Especially when it takes off from the bus station, and the Turbo spins up😍
The 4 cylinder Detroit diesel series 50 (a cut down version of the ubiquitous series 60) was a very reliable and distinctively sounding engine, which became the go to power plant for city transit fleets for a decade after the two cycle Detroit’s were phased out for emissions reasons. Worthy of an honourable mention.
My favourite bus engine is the Volvo DH10A engine. It was used in those old Volvo B10-BLE buses. They're out of service now, but they were legendary. I live in the UK but I think they were in service elsewhere.
The V12 Mercedes-Benz was an 20Liters engine. During the '70s-'80s in Italy was built an Iveco V8 17.1liters and 352Hp Naturally Aspirated bus, the Iveco 370.12.35. This engine was an symphony and it's one of mind because i became busdriver. I also drive the Scania 9 line engine and like a ever 5 straight cylinder it it screaming!
This needs to be a multi part series!! 6V71 Detriot. Commer TS3 "Knocker" Foden 2 stroke diesel. Leyland 510 in their National bus Leyland 0600 and 0680 and TL11. Gardner LW and 6LXB Mercedes OM407and OM447 inline six engines and very similar MAN counterparts D2566 and D2866, used in Mercedes 0305 & 0405, MAN SL200 & SL202 buses (SL202 using both). AEC 590, 690, 691, 760 (Later the Leyland TL12). 590 used in London's famous Routemaster deckers. Older AEC 9.6L used in the mighty RT deckers. Cummins L10. 11 litre engine used in Scania L113 series buses. Scania V8 trucks as well as inline sixes from the 80s. Volvo 9.6 TD series bus engines. 12 litre used in B12 coaches and buses. Many many more.
My city uses Volvo B8RLE (350bhp, 1400NM) and Mercedes-Benz Citaro (360bhp, 1800NM) Due to busy traffic the drivers often have to do boosted launches to cross intersections its very fun.
