It sounds good, just seem like it revs kinda high before upshifting. The engine fan is kinda loud but not nearly as loud as the ones on the Cummins Visions so it’s not that bad. Nice video!
But it hauls ass...he was at a light and when he put his foot down he FLEW past that minivan...althiugh not a fan of the quietness. I Like to hear the engine at work...
It's nearly identical to that of the Cummins (Which is now just the B series). There are charts out there which show the torque curves side by side. The DT always seemed to rev higher, but some of that may be transmission programming.
I see. From what I remember (from 2008-2011 buses), scientifically-measured in how hard I got pushed back in the seat, it seems like a DT had more power at the low end (from takeoff) than a Cummins (more gradual). Maybe gearing or HP was different, though.
Yeah, horsepower and gearing can make a huge difference. Most IC's in NY run 6.14 gearing, some as high as 6.50 so they have major torque on take off. It's common in states with flat terrain to have 5.97 gearing which is fine on level ground but horrible on hills.
@@caleb0606it’s the tires. I know because my bus which is an ic CEs had similar sounding tires from new. The axle whine usually goes away when the gas pedal isn’t being pushed.
@@jstkyoshi I would say yes to that, generally. Comparatively, a diesel that kicks itself into high idle will warm up just as quickly as a gas left at normal idle, based on my testing. If both are idling normally, the Gas/Propane will warm up a bit quicker.
@@KodieSOh alright, cool. Would you also say that the likelyhood of diesels (mostly older ones) taking longer to warm up in the winter is because of the viscosity of engine oil used? Perhaps a thinner oil in the winter would circulate better and allow for quicker warm ups? :o
@@jstkyoshi I don't think the viscosity plays a part, it's not that far different than that of a gasoline engine. The core functional differences between gasoline and diesel are the bigger factor. Gasoline engines as you know use spark ignition to fire, creating a high heat situation pretty quickly, whereas diesels rely on compression, creating high heat as well, but in a different way.
@@KodieS My district has them on all most all of their air brake buses, whenever I talk about them to people they don't even know what it is. I've noticed alot of New York districts will have them when they go up on the auction.
@@CentralJerseyRailfan you mean MFDT and MF7? To me in between I like the DT a little better than the 7. I mean the Maxxforce 7 is not too bad but I'd ride a CE200 with a Maxxforce 7 over that late VT365, AKA 6.0L Powerstroke. Maxxforce is alot quieter than the old Navistar IC Bus Diesel engines.
That’s so true like my girl 794 she’s sounds really loud from the outside since she have 270 horsepower 8.8 liter v8 gasoline 🤩🥰🥰🤟🏻she’s a handicap bus 🚌shorty 10 seats in three wheelchairs rows highback seats for the students in is got the bodysafeguard seatbelts in it like the car truck style seatbelt they don’t use the lap around seatbelts anymore which is much more safer than the lap around one in she rides really smooth Kodie 🤩🤟🏻🤟🏻🙃🙃🤩🤩😉
Idk man these propane’s don’t have much power and the way they sound I would get a head ache. Rather listen to a DT466e or a MaxxForce DT. Or a Detroit diesel. Edit: VT365

I’m glad the engine fan kicks in as much as it did, love to hear a good roar coming from the hood, quiet engines are boring. Nice vid and drive
Jean Dolce What about when the bus is loud on a long trip?
Buses and trucks weren’t traditionally made to be quiet, they were meant to serve their purpose and get the job done.
@@jeandolce838 You're totally correct!
This was a fun School Bus ride Mr. Kodie.
Love how quiet they made they 2018 ic ce’s. I drive one this year and love it.
This thing is really quiet, although the engine fan is a complete buzz kill. The bus is beautiful
The bus sounds great to me. It is not often that you see a class 8 bus keep up with the car traffic!
Brings me back to Freshman year i rode on a Gasoline 8.8L

03-12 Productions How loud were they compared to the fans on MFDT CEs?
CentralJerseyRailfan th-cam.com/video/Z34qKJFPfh4/w-d-xo.html I recommend watching with headphones to really hear the difference.
I LOVE HOW IT SOUNDS WHEN THE FAN TURNS OFF 2:55
Is that the 8.8 L? What school district do you work for? We used to run propane in the school buses in Bend Oregon.
My school district recently got some propane buses
Where are the new videos
Wow, very quiet! Do you find it has the same torque curve as an ISB or DT, or does it need to rev more for power?
It's nearly identical to that of the Cummins (Which is now just the B series). There are charts out there which show the torque curves side by side. The DT always seemed to rev higher, but some of that may be transmission programming.

The ISB was comparable to the MaxxForce 7, and was also offered by International as an engine option for repower. The Cummins ISB redlines at 3,000 RPM, irreparable engine damage results at 3,400 RPM.
MaxxForce DT redlines at 3200 RPM, again or irreparable engine damage.
A gas engine usually redlines at 4,500 RPM or higher depending on design.

I wish those propane and gasoline engines sounded as good as Diesel engines, especially on the bluebirds
Wow she's really quiet except for the engine fan...
Jerry Sylvester you don’t hear the ever prevalent axle whine?
That has been a common problem since the S1900.
Actually the axle whine sounds nice!
@@caleb0606it’s the tires. I know because my bus which is an ic CEs had similar sounding tires from new. The axle whine usually goes away when the gas pedal isn’t being pushed.
I had the pleasure of driving a2019 blue bird propane
You were out by Williamsville?
Love it!
Is that a loading brake release rocker switch I see? Never seen any other district with them. We use them on our 2009's and up at North Syracuse.
Yeah, they're fairly common across the state.
@@MurdamanTy In New York state, it's an option. It is ordered by many districts, but is not required.
What is this switch you speak of?
Beautiful bus. That fan always on? or is it just because it's a relatively warm day?
It was warm, it shuts off a few minutes into the video.
@@KodieS Beautiful bus Kodie, hope i get to drive one soon. Im sure it warms up much faster than the diesels in winter right?
@@jstkyoshi I would say yes to that, generally. Comparatively, a diesel that kicks itself into high idle will warm up just as quickly as a gas left at normal idle, based on my testing. If both are idling normally, the Gas/Propane will warm up a bit quicker.

What is the driving range on these propane models?
My district have propane buses and shorty, and they sound quiet and kinda fast
I sell propane and propane accessories.
LOL
Now I get it 😂from King of the Hill
Sounds Like Our 2017 IC CE Propane Indiana Spec
Ips?
@@mareyonsmith8761 Yes Indianapolis Public Schools
Honestly sounds like the fan is running 24/7
It’s the tires.
Did you just get that bus recently Kodie?
This is a demo/loaner unit.
@@KodieS What is the normal bus you normally drive?
4:28 there's a bee on my bus.
This should be the future not electric
Surprised there's another district using Ped-Loks.
There are a ton of them that use that system.
@@KodieS My district has them on all most all of their air brake buses, whenever I talk about them to people they don't even know what it is. I've noticed alot of New York districts will have them when they go up on the auction.
Sounds like it's not even on
We have a 2017 ic ce propane
This is in western New York!
I live there! In East Amherst to be exact not to far from this run used to work at the regal on transit.
This kinda sounds like a zf transmission

I’m am riding a 2020 ic ce propane special ed bus 🥰👍🏻
I ride a 2015 Thomas Saf T Liner C2 special Ed bus
I ride a 2013 bluebird vision handicap short bus
What strange corner of TH-cam did I find myself in....

Oh yea I know where you are
That thing is loud
Not as loud as a MFDT or B6.7.
But no louder than Bluebird's propane engine.

Edit: VT365
Yep and i constantly remind myself we all have our opinions
Depends. These propane ones that IC Bus makes have a flat torque curve and an awful lot of torque. IDK about others, though...
Especially when they accelerate its sounds awful
Shut up bro
