    • @MichalKobuszewski
      @MichalKobuszewski Месяц назад +7

      I wonder how much of the actual exhaust system behaviour could have been predicted at that time during the design phase. It sounds like the beating between the pipe resonance frequency and the actual exhaust gas pulses might affect the engine by periodically aiding or impairing the scavenging (just a wild guess). Aside from reducing the Q of the pipe to "spread" the resonance, could this be controlled somehow? Perhaps mixing in the pressure wave from another cylinder is enough?

      This is one of those things that, if you know what's actually going on, feels criminally oversimplified as a model. It never had any right to sound remotely plausible at all. But as more fidelity gets added over time, it'll get closer and closer, until at some point it becomes indistinguishable from recorded sounds of the real thing.
      I wouldn't be surprised if at some stage this becomes mature enough to be picked up by the engineering teams working on real engines as a first pass to weed out the silliest ideas before any real CFD gets done.

    The trick to having multiple things operating on a single state is to double-buffer it so that CPU is reading from previous frame's output, and GPU is rendering with it, while CPU (or whatever device is performing the simulation step) outputs the simulation increment to a back buffer. Then you swap the buffers' roles. I'm sure you're well aware of double buffering, but sometimes we forget things!

  • @ceremyjlarkson9475
    @ceremyjlarkson9475 Месяц назад +36

    If I'm not mistaken, the wobbling you spoke about at 15:46 is a result of exhaust air resonating in the system. I think that sound happens irl too with some exhaust systems. You'll of course want to check and verify but if it is because of a physical property and not an issue with the sim, it means you're doing very good with the exhaust side of the simulation

      I haven't heard of this phenomenon before, but I know in my NA 2.0l focus, there's a noticeable shift in tone between 3-4k rpm and it changes in almost exactly the same way as the simulation. Sounds throatier, almost like there's a lower octave that creeps in and out as you go through the rpms. Again not sure of the mechanics of it, but it seems the simulation matches reality.

      @@themonsterodub I'm not entirely sure if that is exactly the case either. Going off of memory, when the air is being compressed by the piston going up in the exhaust stroke (this increases the pressure in the exhaust) there's a return shockwave that can constructively interfere with the exhaust air that is being expelled. I am curious if that is indeed how it works but I wouldn't be surprised if it was some other mechanism

    edit: while looking at the video again, the wobble appears when the presure in the intake valve increases, due to the high rpms/load ratio, some vehicle's get rid of that with some exaust desing but definetly this is prof that your simulator works beautifully

    Allow me to contextualize the following: I am a 20+ year master mechanic, who has personally owned, worked on, and operated 13 different cars/trucks, and 13 different motorcycles, and worked on countless others. I am mildly autistic, and thoroughly fascinated with the operation, and the SOUND of each and every component of an engine. With these traits in mind, I trend towards objectivity, and less towards overlaying my preferences and emotions (remember: autism. How to emotion??). I tell you that to tell you this: I'd like to express my observation, that those who seem to criticize and question the thing they have no control over, seem to react as such (YOUR project vs THEIR experience - come on, people. LET HIM COOK.).
    That being out of the way, I hope it provided context for my next statements. I have been following your progress on your previous projects, and I am thrilled that the almighty algorithm has favored you - YOU. HAVE. EARNED. IT. The path, and every milestone along the way, has lead you here. And I am ecstatic that it has. I am thrilled to be able to observe the fruits of your labor grow!
    I have trust and faith in the way you are tackling this project. I have a DEEP appreciation for everything you've done to create as accurate a simulation as possible. I'm not a programmer, nor am I an engineer. But I'm thoroughly impressed at the now raw, procedural sound you've managed to replicate - I was really tickled at how the old sim had additional audio processing to achieve SOME level of real-world sound, and how the new sim doesn't need it at all to sound just about perfect to real world!
    I am particularly interested at the content after the 16:00 minute mark - the 'wobble'. My intuition on the subject, and the reason I've decided to write and share, is thus: I have experienced this resonance, especially on motorcycles, where the experience is very raw, direct, and visceral. I think your simulation is extremely accurate! Resonance is a very big deal in the world of engineering an engine - it is absolutely crucial to scavenging, efficiency and performance. I know you already know that. So on to my intuition. If it's simulated, rather than addressing your code, which I feel the results would suggest is very accurate, I'd point you towards the area and angles of the intake and exhaust ports (particularly the exhaust, but both matter) and see if it does not directly correlate with a change in the behavior of the resonance 'wobble.' If these parameters are simulated, and changes to the design of the ports results in a direct change in the behavior of the resonance, I think we can reasonably conclude that you're 100% on the right track!
    And if these parameters are not simulated, then I am talking directly out the wrong cheeks and I would be embarrassed to have written this college paper and consumed your time in vain.
    Either way - I love what you're doing. I'd hazard a guess that most people who view, but do not comment, feel similarly, and trust and understand the kitchen is properly staffed - and those who criticize are the exact same people in starbucks saying their drink needs more ginger, and when the employee takes the cup, turns around and turns on the grinder for 8 seconds, then hands the customer the exact same drink, unchanged, who then take a sip and say, "perfect"!

    Something i've noticed with car's exhaust is what i call the drainpipe effect. When the exit of the exhaust has a long unmuffled pipe section beforehand, for example vehicle with 2 mufflers but with rear muffler replaced with pipe, there's a certain warbling resonance that can be heard.
    Engine Simulator 2 has it, that sound was there around 15:17. Superb work.

  • @logtrimmer
    @logtrimmer Месяц назад +26

    One thing you mentioned were junctions. I think those might help out with the simulation because instead of having to simulate multiple long pipes, there would just be the one pipe leaving the engine. I do know that exhaust systems tend to split and merge multiple times depending on the vehicle so it seems like something that is quite important to the sound.
    But regardless, this is a project I am deeply interested in. I have spoken to many people about this irl including my college professors. One of them even wanted to see about having you come in to present ES2D and ES3D.

      He did say not supported YET! So it is a feature he is going to implement. But what you have mentionned is true engin sound does matter depending on the exhaust configuration, just search up x pipe vs h pipe that already makes a big difference in sound depending on the car.

    When you showed the exaust noises getting lower when you made the pipes longer, I thought "Of course, this is how a trombone works."
    I dont know if it would come across, but I find the idea of the moveable bend of a trombone as part of some engines exaust hilarious. Maybe you can use that in some semi-serious testing. :D

    As an audio engineer, the output sounds bandwidth-limited.
    Keep in mind that to reproduce the full range of human hearing you need a sampling rate of DOUBLE the top end of our hearing range. We hear up to around 20kHz, so to be able to reproduce those frequencies we hear as “air” or “crispiness” your sample rate needs to be north of 40kHz.
    Common sample rates include 44.1kHz, 48kHz, 88.2kHz, and 96kHz.
    96kHz is what I typically work at, as it allows for gentler, more transparent anti-aliasing filters during upsampling and resampling.
    I’m sure your computer sound card is running at 44.1kHz or 48kHz, but if your simulation is only generating data at 20kHz or so, the resulting audio can only reproduce up to 10kHz, which could explain why it sounds so muffled

      I suppose the actual reason is turbulence being hard to model precisely enough at high speeds. Also as far a I understand, this is the raw exhaust sound only, while there are other mechanical parts in an engine that also produce noise, but not simulated here.
