I was disappointed when this was removed, but apparently it was because people were able to make infinite generators with them. I'm really hoping they add this back in, or at least add a different part that accepts fluid and outputs torque but doesn't work the other way around as a pump. This way the torque output could be scaled down to where infinite generators aren't possible. Maybe some day 🤞

@SheepInACart

+1 to cooling being next, its far from intuitive since the restriction of cooling water has so much effect. For now though I find engines work as one large tank of fluid (shared between all cylinders), and cooling manifolds like fluid ports. Try pairing a single radiator with each cooling manifold, and using a pump both into and out of the manifold, as that will maximize the water flow, thus minimize the difference between engine temperature and radiator temperature. Also nuclear reactors, fireboxes and heaters emit heat in a radius around them, so if you place radiators in that distance they will heat up (even if in a different sealed space)... I find for small creations you need to use a thermometer and threshold to limit your heaters to ~20'c, since otherwise your engines (or steam condensers) overheat as cooling system can't be far enough away, and as a bonus your battery will last longer.

How about comparing fuel consumption while putting out the same power?

You missed out on a pump! you should have tested the large impeller

At some point in this testing series I'd love to see an efficiency comparison of power generation per fuel used, for these different engine setups. Preferably using gearboxes to give a fixed RPS, as fuel consumption rises _dramatically_ with RPS. iirc, from my testing it seems like around 7.5 to 8.5 rps is the sweet spot (which could be something else to test).

@tymoteuszkazubski2755

I think the best way to compare engines is to pick a load and RPS to do testing at. Then use controller to maintain said RPS . You can then estimate engine load by reading air throttle (in my latest tests even at max pressure air throttle was higher than fuel throttle) lower value means more power to spare and compare fuel efficiency by measuring fuel flow, lower flow is better. If you are testing anything keep variables to the minimum, it makes for better end easier to analyze data.

Amazing video, perfectly laid out and well explained!

One thing I found out when I was building me train engine. Is that the exhaust amount can have an effect on the engine performance. I originally had two both were connected to each engine but I was only getting low row. I then added an exhaust to each cylinder and it got way higher rpm. I’m not sure if you know already.

@SheepInACart

Yep, and where this gets weird is catalytic converters, which cause some restriction to flow, but actually reduce the total amount of fluid. Thus if you put a converter on each exhaust port you can collect several ports together to a single fluid port without meaningfully impacting flow more than if each converter had its own fluid port attached.

That way we see the full performance of the engine without the losses in power from driving the pump.

Problem is that you will have to drive the compressor somehow, with a supercharger that’s commonly done from the crankshaft and with a turbo from the exhaust pressure (not possible in Stormworks), I guess it’s more inefficient to drive the pump directly (or with a gearbox) from the engine instead of first converting into electricity and than back into rotational power, so this is probably the most realistic for use in a creation

Any chance you could cover supercharging or building large radial 5x5s? I can't seem to get enough fuel or air into them to get their full potential.

I already changed my air to fuel ratio to 12 to 6 for better performance out of the flat 8 cylinder ship engines, already my 6 deck cruise ship can easily reach 30 knots, I might give the large pump a try if it is needed, though my engines will use a lot of fuel. Testing I have done with the large impeller pump disappointed me, the engine actually lost power from powering the impeller pump.

I really feel like fluid being forced through an impeller pump should produce rotary power output

I built one for my engine. Basically doubled the performance and as well as fuel consumption.

Are you pulling the fuel usage from the composite data? I'm using fuel tank levels and can't get the steady numbers you got. Great job with all your posts.

So a bank of impeller pumps to all inputs and outputs might prove a great option to improve compact engines

Thank you so much for the tutorials I made my first custom engine recently thank you. You can and will always learn.

Sadly in my testing nothing useful. Pumps in game don't actually seem to raise the air temperature meaningfully, so adding an intercooler doesn't actually help performance, its just another restriction to flow. Its a sound concept in real life though, so was certainly worth a try.

I kind of wish they'd add back in a turbo. I'd love to Turbo Charge (having both a super charger and a turbo charger) an engine. I'd actually like to see you super charge the old engines and see if you can get better performance out of them. I wish that there was something like that for jet engines, like spool the fans up faster or something, but for now, I'd love to see if like a prop plane has better performance with a supercharger. Not that it'd be super interesting or something you'd need to do, but I'm wondering at what point does the extra power become outweighed by the extra fuel needed? Like a standard engine on an airplane (since weight is most crucial on aircrafts) will go X far. Will a super charged plane of the exact same stats save for that super charger go a farther or shorter distance that the standard? If shorter, can you add more fuel tanks to make it just as far or is there no point in doing that? If the case is that it's a bigger waste of fuel than power benefit, we might want to rethink this and think of a dual intake system where you have just a normal intake through one pipe with a valve and then a pumped intake on a closed valve on the other and being able to swap between more air (more power) and cruising power would be a bit more sensible.

@SheepInACart

The turbo was a great idea, but the issue is the game doesn't have internally consistent maths as to represent conservation of energy, so having parts that turned pressure back to shaft power created many unintuitive and game breaking issues (indeed even wheels represent a simlar problem, and electric generators had to be radically reduced in efficiency to prevent the direct "generator powers the motor" being an infinite energy system). IMO the easy solution would be to make the turbo a single part with 4 fluid ports (compressor in/out, turbine in/out), but honestly it wouldn't add much in the way of meaningful player choices to the game simply using an electric pump doesn't. Jet engine wise, you can use multiple combusters to get more power (for more fuel), or multiple turbines (in parallel rather than series seems to work best) to increase shaft power, you can scale this out to stupendous amounts (devs admit jets are overpowered, but aren't fixing as it'd break all the existing creations). Aircraft wise, you'll normally go less distance for a given amount of fuel carried by increasing power, as drag goes up rapidly with speed. However in stormworks you often can improve economy by supercharinging then reducing engine RPS till you only make simlar power, at which point if you go further or not is a function of what the supercharger weighs vs the total amount of fuel carried. A large pump weighs 20kg, so if it improves fuel economy 10% to fit one, you'd really want ~250kg of fuel weight (including the tanks ect) before fitting it would work out. That said you don't need a second intake manifold, simply putting a one way valve in parallel with the pump will have the same result when you turn the pump off... although this only saves you the electrical power needed to run it, as the actual efficiency of the engine isn't reduced in stormworks from simply reducing the throttle, assuming the engine size/temperature/rps remains the same, 100% throttle naturally aspirated and whatever % it takes to make the same power supercharged will require the exact same fuel manifold throttle, and flow the same liters of fuel per minute. So all that said, there will be very few instances where its worth adding extra equipment to bypass a supercharger on an aircraft, simply run the engine at max boost all the time, and ideally control the power output via gearing, but otherwise close the throttle a bit. Finally word pedantry, but common use of the word "turbo" is a contraction of "turbo-supercharger", referring to a supercharger driven by a turbine rather than shaft power (alternately turbo-electric being a electrical generator driven by a turbine, as used by many steam ships). "Turbo-charging" is simply adding a turbo to a engine to increase the intake charge air pressure/flow. There isn't a specific word that maps to hybrid setups with both an exhaust driven turbine and engine driven supercharger, with "twin charging" in some parts of the world referring to this setup, but in others used equally for two turbo's on the same motor.

You missed the large impeller pump

For me the first method with the belt driven pump doesn't actually supply any amount of air to the engine. I end up reading out with "too much fuel" (I've made sure to set the controller to supercharger ON). I've noticed the logic requires a clutch pressure input for the pump but I have no clue what to connect it to. Am I overthinking here?

could you use a small electric motor for the impeller pump?

i tried turbocharged, so an impeller pump connected to the exhaust pipes, then the power output of that impeller pump is spinning another impeller pump that is forcing air into the engine. don't actually know if it worked or not cause I didn't see any big increase (also because i was bored and stopped trying to perfect the engine).

Doesn't temperature affect the stoichiometric and so change the efficiency or power of the engine independent to supercharge? Instead of the pumps one could add more cylinder, increasing power and fuel consumption as well. Basically comes down to power for fuel consumption.

Testing is unfair: the electrically driven pumps are "free" (draining the battery), while the shaft driven pumps engines are using energy. This needs to be accounted for! And since engines seem to be more efficient at low RPS, high load (high clutch), we need to attempt different RPS ... Since the generator is the target output, I would suggest: - set a number of generator power setting as target - go over a wide range of RPS/clutch combinations to get the power, record the fuel usage - check RPS/torque conversion using gears, allowing the engine to run at higher/lower RPS than without, see if we can get the engine into the most efficient band - for the belt driven pump, see if changing the pump clutch changes the equation - for impeller driven pumps, see if a clutch and/or gearing does change the equation - for the electrically driven pumps, we need to subtract the electrical power used from the generator output - for the electrically driven pumps, see if a tank as a reservoir and a pressure-operated on/off switch for the pump reduced the electrical power needed - and vary over a range from lean to rich air-fuel mixture --- or have some automated tuning select the most efficient combination (a smoothed first order derivative of the RPS may be a good indicator), then change the throttle to get back to target RPS, repeat until we are there - also, we need to control the engine temperature --- I have reasons to believe that it can effect the efficiency. As your engines were not running at the identical RPM, they might have run under different efficiencies.

You forgot the large impeller pump

can you try to make a botnia targa?

does that work too for the steam?

Yes, placing a large electric pump on both intake and exhaust of your steam turbines will increase their flow/power... IMO this should be patched out as it doesn't make much sense (and indeed connecting a pipe between those two pumps will let you produce infinite power without needing any more steam, so is an infinite energy exploit), but as it currently stands its a good way to boost the power to weight/volume/cost of your steam engines. On the other hand there is no point supercharging the firebox, as you can't apply enough useful load to it anyway, and so doing the opposite (restricting intake or exhaust with a variable throttle valve) will let you get as hot as needed produce the same boiler pressure (and thus steam power) with less coal use... fancy way to drive the valve is a PID, but even just a throttle or keypad works fine.

I tried twin supercharger (2 large electric pumps) once. Not worth it.

Is there a reason the large impeller wasn't tested?

They take a ton of force to actually use.

I added one to a regular engine it didn't seem to do anything

Yes.

yo wut if u have twin and quad superchargers

I tried twin and it did not give me much though i could've been doing it wrong

"now im not gonna do an actual cooling system because they are a myth for modular engines and I cant make a real one"

Cooling systems are complicated and not easily understood. But they do work, just not the way everyone expects them to work.

When are you coming back?

Can you publicate the ecu? Or just send it to me?

MO POWA BABEH

you should try the 4 turbo charger configurations as well to see how much they help as well.

Proper way of comparing numbers is to wait for the system to settle. You should have started the engines and let them do their job for about 5 minutes before looking at numbers.

Turbo in normal dishel engine is working

Just to ask; Is anyone else still unhappy with modular engine cooling?
