Gigantic 5 Rotor Diesel Drag Engine (666 Cubic Inches!) - AngeTheGreat's Engine Simulator

This massive engine is just one more rotor stacked onto the previous 4 rotor, but its over 10 liters in displacement, or 666 cubic inches. What a devilish motor this monster is. It makes nearly 2600 horsepower and over 5200 pound-feet of torque, propelling this 6.5 ton monster of a chassis through its 25 speed gearbox to a top speed of just over 250 miles per hour. It takes a little while to get there, being so heavy and huge its got a decent amount more drag than the smaller 5.5 ton that held the 4 rotor and more rolling resistance with slightly taller tyres and a slightly shorter differential ratio.

If it wasn't for the Fuel consumption then this makes this engine viable for commercial use

[@Avetho]

Also the reliability aspect, as I mentioned a few seconds ago in my reply to your other comment this motor would likely have way too much in the way of stresses to survive at this size and with all this torque. From what I understand, Wankel engines can make big torque, for sure, but they don't tend to survive that too well, as parts holding the rotor housings together as well as supporting the eccentric shaft begin to flex and push apart and twist a bit. Rob Dahm, after taking his 4 rotor apart, noticed the studs had bent due to the housings pushing apart on the spark plug side of the motor, as least as far as I can recall, and that problem presumably only gets worse the longer the motor is, so 5 rotors would be less reliable than 4, and a single rotor, or several of them, would be the best for reliability. Ignoring the old oil burning intrinsic issue, of course, but they're still very cool and fun motors.

Sounds kinda like 5cyl/v10's, incredible.

[@acebinko1]

I really love the sound. I like that you actually made a long video of going through the engine at different stages and some features of the simulator. In the future, you could consider adding something (maybe visually only so as to not disrupt the sound experience), that makes it clear what command or keys you are entering? I like watching the gauges and graphs change, and I have to pause for a second and rewind (for instance your start up sequence was: ignition on, ignition off, ignition on, increase speed, ignition off) if you make it clear that this is the startup sequence, I think the videos would be more enjoyable to an audience that may not be as interested in the technical nature of this video.

[@Avetho]

Well, I guess for those who haven't used the program they wouldn't know what keys do what, but those who do use it have read the readme file on the GitHub page where they got it from. The startup sequence isn't anything special either, I just turn on the ignition, hit the starter and if it doesn't kick over I blip the gas like you'd do in a car IRL to make the accelerator pump push more fuel and drop the AFR from 40-1 down to under 30-1, and from there the engine quickly warms up and begins to hold at idle. So the startup is: Ignition On, Starter On, Partial Throttle, leave it at idle. I only engaged the starter without ignition to let you hear the pumping of the engine without an exhaust note. Now, I could probably fashion an engine with an odd startup sequence, but all of them so far are just Ignition > Starter > Throttle if it isn't starting yet. I try my best to make it user-friendly XD

@@Avetho this Engine Simulator is extremely impressive for natural aspiration only!!! I would love to tool with the audio render settings (EQ, compression), or tool with the "car" settings like gearing, weight, or even a way to adjust engine parameters (valve timing and lift, ignition timing, fueling map, etc.) - all through the GUI somehow. If I could code it I literally would, your base code algos are art - and you can hear it!

[@camarocharger8180]

I need this engine in American and Euro Truck Sim, what a fun experience that would be to haul with that soundtrack.

[@Avetho]

That would be amazing! I would try but every time I attempt to figure out FMOD, I get a migraine. Well, not literally, but I've never been able to figure out how to create a completely custom sound bank for even an Assetto Corsa vehicle, let alone the bigger ones for ATS and ETS which contain things like warning chimes, blinkers, lights, other switches, brakes, all of those things.

Bruh got 25 gear transmission, talk about huge transmission system!

[@Avetho]

24-speed gearboxes do exist in transport trucks, so a 25 doesn't feel that out there to me XD Given Koenigsegg have the Jesko's 9-speed using two pairs of 3 gear sets, basically base-3 counting times 2 gives 9 speeds as the first set is engaged and shifts through the second shaft's three sets like ranges on a bicycle, this would be a far bigger and beefier base-5 of two pairs of 5 gear sets shifting automatically through the gears like a bicycle with 5 ranges. Of course, the gear ratios don't behave like that at all, I would've had to spend a couple hours calculating out the stuff since I'd have to learn how compound gear ratios work, maybe make an Excel spreadsheet to determine five ranges of gears and multiple each to find the total gear ratio before the differential ratio and all that, actually I might do that for my next Engine Simulator video since you got me thinking about it and it sounds interesting now... oh well :P

[@JohnNecirRebellion]

And this isn't super/turbo charged even. 2,5K HP?

[@Avetho]

Yep. I did some quick calculations also, the Mazda 787b's 4 rotor motor was also naturally aspirated, but it had only 158.7 cubic inches of displacement, so this being 4.2 times larger and revving far lower with a focus on torque means it could be reasonably realistic, if not for the high likelihood that it would break down from all the stress of such huge rotors. The 787b in top form made 900 horsepower with no forced induction, and a 4 rotor can surpass 2000 with a big turbo if properly built, so if someone custom machined rotors and other parts to make this motor, it could work, but it would be a massive undertaking.

[@JohnNecirRebellion]

@@Avetho Yep I totally agree.

[@JohnNecirRebellion]

@@Avetho Also if they have a low revving, or very efficient rpm for generating power/electricity, this could even beat conventional generators

You could never have a diesel rotary cause it won't work

[@Avetho]

Well, you are technically right, since although diesel wankel engines have been made, most of them weren't capable of running off a test bench, and the one that did didn't really go anywhere. There was hype in the early 2000s about the 2116R Rotary Rex engine, which was 11.6 liters and two rotors and made 1000 horsepower, or at least RPI said it did, but it never went into production due to its very high price and RPI kind of went defunct by 2011 after making smaller versions and not getting much traction from what I recall reading. So that engine could technically be a hindsight inspiration for these engines XD

@@jameshatton4211 Your welcome, I have a load of random facts floating around in my brain, and when I see something that pings that random knowledge that I've lost somewhere in the reaches of my memory I get an impulse to try to recall it, usually just going onto Google and pinpointing articles on it to refresh my memories, and I like to share that with others.

@@Avetho may I ask your age? The way you speak and communicate is like how I do. I'm like a "hanger-on-era" from the forum days? Where posts were about knowledge and thought provoking topics? I've got a project car. A Mazda RX7 Series 4 1988 model (60,000 miles on the clock) all converted series 5 infini (rare 2 seater model with fixed back racing seats genuine made from mazda in purple suede 👌) it's full wide body +70mm rear +45mm front all metal fab front fenders no fingerless rubbish. Even the fuel flap had been pumped out to sit flush with the body retains all the factory lever and factory filter 👌. Brand new 13B REW series 8 RX7 motor last of the 10 built from Japan came wrapped in plastic 👌 Triple plate clutch Water injection CDI T04Z roller bearing turbo V mount cooler Aviation oil drive block kit to inject 2 stroke instead of sump oil 😉 New gearbox New mechanical 1.5 way LSD Custom intake plenum etc etc I'm running a 11mm CNC baffle plate across the bottom of the motor as an experiment to see if this can mitigate the need for doweling the motor? We'll see 🤔 List is large. I'm running Haraguchi's Formula D1 front steering rack and knuckles off everything from his D1 race car 😎 Water injection is a style similar to how WW2 German planes used to run. There's a whole world of knowledge in those translations that can bring the rotary engine to life much better than any porting can for a street car (in my opinion) It will blow people's minds to know that those planes in WW2 were running over 200 pounds of boost 50 : 50 water to fuel and over a million volts of delayed capacitative spark ignition system! 😲 Also another sideways theory I'm going with is not going with a massive rear turbo housing at all. I'm going with massive twin 50mm waste gates though! You put the soloid control in as another map into the ECU and tune in 3D keeping boost pressure as the constant 😉 where people think the rear housing is going to "choke" 🙄 it will never choke if you relieve that pressure like it's almost naturally aspirated? You are basically bleeding off exhaust pressure enough to keep the turbo spinning to the required boost pressure! No boost spikes either i can guarantee that 💯%
