Testing Piston Engines on Dynos in the NEW Engine UPDATE!

In this episode we are back in Gearblocks in the pre-release branch looking at the new engines! The dev has been working on internal combustion engines and they are super cool to play with so I decided to test them on a dyno and see how they perform!

kan, one kw is more than 1hp, so the 93kw i4 actually makes around 120hp

[@kANGaming]

Whoops I did the math backwards because I'm dumb.

@@kANGaming yea i noticed that xd

[@kornaros96]

@@kANGaming as per the allknowing G: "To convert power from kilowatts (kW) to PS, multiply the power value in kW by 1.35962" "There are approximately 0.73549875 kW in 1 PS." Edit: PS is just horspower that lifts 75 kg up 1 m in 1 s.

This is the coolest thing I've seen in Gearblocks yet. Honestly can't wait to get back to building more stuff with these new engines.

[@jamesburghgraef2143]

are we able to try the engine stuff ??

[@kANGaming]

@@jamesburghgraef2143 yes it is available in the pre release beta branch on steam

[@cdmaddles]

you should revisit stormworks

[@jesusmurillo8652]

What do you mean pre release branch?

[@aggressivertyp9663]

​@@jesusmurillo8652steam allows developers to release betas for updates in which you get early access to new stuff at the cost of more bugs. Devs mostly use it to gather feedback before releasing to everyone

[@blueflame_sm]

kAN't wait for him to figure out the dev also added a script to graph all those things ;) for the angled crankshaft, it has settings with shift+E.

[@KPen3750]

I love how all the engine types actually sound like they should irl. the Straight 6 sounded like a Jag or Nissan engine, its so impressive

[@djaydeved]

eeehhh from what i hear and experienced with makin em they are all 2 cycle engines, hit every revolution, rather than a 4 stroke like most engines also, rpm limit of 3k, makes it kinda diesel like all ima say, is perfect 2 cycle detroit engines bit big tho, 1700CC per cylinder, ~107 CI, 3 less than the biggest of the 2 cycle detroits.

[@bogre5056]

the i4 was ridiculous

[@Londel3gaming]

​@@djaydevedyou can bypass the 3k rpm limit by right clicking the value and typing it in yourself

[@djaydeved]

@@Londel3gaming ik ive made a 64 cylinder radial rotary engine that revs out to 6k also, it makes heck all power out that point

[@neil2796]

People nerding out over things makes me happy.

[@BraydonAttoe-xs4yg]

Isnt it wild that... playing this game requires more brain power than modding other ones

[@Steinersgarage]

It doesn’t?

[@davidaugustofc2574]

Most creative games are like that

[@NovumSB]

i kinda disagree

[@gabrielvieira6529]

Agreed. I find it easier to buy the things and do it myself rather on this game. The worlds most amazing game is useless because how wanky it is

[@Steinersgarage]

@@gabrielvieira6529 it is litteraly super easy to play?

[@0megaming]

I´d say the dev could put exhaust pipes in, that make the engines sound like different cc classes. Like a gokart or moped exhaust could sound very legit, as well as some inline 6 tractor engines, a low brobbling V8 and so on ^^

[@NovumSB]

Yes

[@The_Envix]

Whats more satisfying than the sound of a fast powerfull engine shifting up and down

[@djplonghead5403]

This is even a step up from stormworks. In stormworks I want better transmission capability and turbos. I want to try to make a true Hybrid. BeamNG also needs a hybrid.

[@Steinersgarage]

Stormworks have awesome transmission capability’s and have forced induction. You just need to make it happen. CVT is even a option in stormworks

[@firewalldaprotogen]

yes! i really also wish for turbos in stormworks. i also want stuff like overlapping logic nodes (as long as they are different types) and stuff like an updated friction system for wheels

[@firewalldaprotogen]

@@Steinersgarage stormworks only has the capability for superchargers, the transmissions are limited by the fixed gear selections, and the "cvt" is just a variable clutch and is not a true cvt (which would be awesome)

[@Adiya_55]

Hearing the engine didn't go past 3000 RPM is so weird, good thing you can adjust the RPM... I can't wait how 10K+RPM V10 or V12 sound...

[@raspyApostle]

The answer: Very glitchy sounding lol

[@Elijah1573]

Currently the engines are modeled as a 2 stroke instead of 4 stroke so its really screaming even at 3000 RPM

[@AquariusGhostHunter]

idk if any of you know this but if you right click on one of those bars you can manually type in numbers. so you can manually set it higher than 3000

[@solerkiper1912]

i dont know if you know about AngeTheGreat but his project hes working on is really cool and it would be so cool if this game some how integrated with it but that is a huge ask

[@thekingjdd]

@Kan the initial stutter is because of low rotating mass the dev should have added a flywheel to smooth everything out... PS just use springs to connect to the sway bar instead of linkages and it should be a decent enough torsion bar facsimile

[@raspyApostle]

The steel dinner plate on each example engine, if im not mistaken, is supposed to act as the flywheel but i could be wrong

[@GamingGuyLV]

@@raspyApostle Nah it was connected after the clutch so it was there more for resistance so the engines don't spin up to max rpm instantly, but adding an actual flywheel does help a lot with the stutters

[@ChevyTech68]

I love how excited Kan gets for mechanical systems lol

[@ZexMaxwell]

I know little about engines. But it brings me joy to watch someone nerd out over their interests.

[@ericsternwood9812]

Oh man! Even the sounds are kinda accurate!

[@hobbyfan6018]

man this is a cool thing they decided to add to the game! love to see a combustion engine on the test car you built a little while ago.

[@yellingintothewind]

Running an engine lean, once it's up to temp and up to speed, substantially improves your fuel economy. When it's cold, you "choke" the engine to make it extra rich to making starting it easier. You're right that from thermodynamic constraints, you'd expect to always aim for stoichiometric, but high energy kinetic constraints are weird.

[@Fantaman900]

VE% is what the engine is actually air pumping amount of it's displacement. A 2 liter engine can't actually pump 2 liters per revolution, because losses past the compression rings, the air flow in and out the engine and valve timing. And don't forget the faster it's spinning the less time there is to fill the cylinder. Also 1kW is 1,36 Horses.

[@davidaugustofc2574]

Love the Gearblocks content

[@tyreni]

Super-ultra-hype for Kan doing technical stuff in Gearblocks and SM!

[@J.Natty_]

Lean mix helps w efficiency as lean leaves unburnt octane but rich mix leaves unburnt fuel overall but a lean mix is better for peak bhp and torque

[@mrsnoopy7557]

And richer can be needed for forced i duction as more air needs more fuel to burn

[@J.Natty_]

@@mrsnoopy7557 yeah also rich fuel helps w/ spooling up turbos faster as there’s more exhaust gasses

[@Jay-kc2pm]

Volumetric efficiency (VE) is the ratio of how much air is actually in the cylinder vs how much could theoretically fit in it, given a specific air density. For example, if a cylinder can hold 100 grams of air, but only has 80 grams at the bottom of it's stroke, it has a VE of 80%. this most significantly affects torque, as higher VE ~= more fuel can be burned, making more power. Engines can also have a volumetric efficiency greater than 1, usually caused either by forced induction (using a turbocharger or supercharger to squeeze more grams of air than would otherwise fit) or by tuning the length of the intake runners such that at a specific RPM, the pulse of air caused by the valve closing on the last intake stroke reflects back in time for the valve to be opening, effectively "forcing induction" while still being naturally aspirated. either way, if you can measure Volumetric Efficiency, it can be a pretty good stand-in for how much torque the engine is making, and thus can give you a rough power estimate without having to directly measure the strain on the crankshaft.

[@thatguytravis9352]

WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO YEAH BABYYYYYYYYYYYYY THAT'S WHAT IVE BEEN WAITING FOR

[@g00gleisgayerthanaids56]

So glad youre back on gearblocks! I vote for a mazda miata build! 5 speed front engine rear wheel drive, perfect track car. The camshaft can be clocked at whatever angle you need, he didnt ignore part collisions, you just needed to check the properties on the camshaft. So you just stack them inline and then clock them as you need for your engine. But the inline 6 is perfectly balanced, so they run forever, whereas the v6 isnt. Theres a reason the straight 6 is still highly regarded, at least in the smaller pickup category.

[@joarthelin4906]

WHOO YEA BABY THATS WHAT WE ARE TALkING ABOUT BABY

[@DS-tj1xf]

Love the gearblox content!

[@Sans-fl4pe]

Try out stormworks again! I can tutor or anything, the modular engjnes may scratch an itch for you

[@lemanbest7356]

This is amazing.

[@jakebaker3299]

Oh yes definitely needs to see more of this game, hopefully they add turbos or superchargers or prochargers now that would be a cherry on top

[@crashingandsmashing7435]

This is amazing

[@oskark312]

there is a motocicle in the demo version's workshop of the game so no problem with balance 4 speed is easy only 2 parts to change gears

[@casperk7310]

finnaly another gearblocks video

[@spazztastic6246]

Variable geometry turbos can mitigate turbo lag pretty well if sized correctly. VGTs are also much more efficient as the pumping loss caused by the increased exhaust pressure of a turbo is considerably smaller than the mechanical loss of a supercharger.

[@Kunzite100]

This game would be so fun in VR. Walk around clipping parts together. Then sit in the car and go for a rip.

[@gamintoaster6220]

love your vids cant wait to see you make a v12 car, also what about boxer engines

[@maximiliangroer993]

It is kW times 1.36 for HP. ( number for american hp is different)

[@ElderonAnalas]

I still think the manual transmission you made that you have to "press 1, pause, press 2" to shift is fine. It simulates pressing the clutch, moving the stick and letting off the clutch. Rather than some fancy sequencal gearbox with no manual clutch or something.

[@UnreasonablyIrrelevant-gv8xx]

I can't wait for this!! Maybe we'll have more advanced fuel systems? Customizable heads? Exhaust systems? Actual cams, followers, and valves? Engine tuning? This is awesome!! Edit: we need a higher max RPM. 3000 for a gasoline engine is really low. Most normal cars rev anywhere from 5000 to 8000

[@crimzonplays1134]

Sick!

[@truckingwithgearheads3190]

I can say as an engine "enthusiasts" (I nerd out over dumb little engine things) I can agree this is the coolest update for a game that I don't even own. I'll damn sure be buying it when I get the money.

[@thesunnynationg]

goes BRRRRRRRRRRT through the compressor 😂😂😂

[@lohostege]

I think they can improve the sound slightly, probably using the exhaust pipes to help alter it, and that'll be sick

[@ElderonAnalas]

Definitely wanna see trying to make an... R6 (?) a six cylinder rotary engine like in an old plane, just 6 pistons on 1 crank.

[@NovumSB]

It would still be called I6 i think

[@unclechris3958]

I love the sound of that inline 6 at low rpm it kinda sounds like a 5.9 Cummings at low rpm

[@C481likestrains]

im at the beginning of the video so idk if you realize this later on but the carburetor (throttle, as its called in game) mixes the fuel with the oxygen, so its totally normal for it to be in open air. the air-fuel mixture happens on the other side of the fly valve, not in front of it. just wanted to clear that up, since you seem to have your stat points everywhere but actual engines

[@mikekuschka998]

Cool fact about superchargers. On Top Fuel and Funny cars. The supercharger takes 750hp to operate. In return we get 10,000hp to the wheel.

[@memerman2606]

Hello kan the EFF is basically the ratio of valve, intake and exhaust area to flow.

[@GrassDirt-r6i]

Love your vids

[@marluna_x]

I can't wait for the first V843

[@ericbonanno5214]

The Volumetric Efficiency could be compression. Which will make sense with them being at 90%. Also, even though the benefit of a V6 is size, the benefit of the I6 is less engine vibration since the rapidly changing forces of the pistons is linear and moving up and down compared to at an angle shifting the engine side to side creating more stress.

[@SeSe3366CLUB]

they made automation with extra steps sound fun i wanna buy this game rn

[@Evildaddy911]

One part I really want is sprag/one-way clutches, especially on gears

[@deadline546]

Not sure if this is part of the game or not but its is a common misconception. Yes the stoichiometric air-fuel ratio is about 14.7:1 to perfectly combust all of the fuel BUT that doesn't necessarily mean that's the AFR that produces the highest amount of power. here is an example I found with some googling "For example, if stoichiometric is 14.7:1, run no leaner than 11% rich for lightly-loaded, normally-aspirated water-cooled engines (~13.1:1 AFR, or Lambda = 0.89) for best power. For forced induction and air-cooled engines, go 22% rich (~11.47:1 AFR, or Lambda = 0.78)."

[@gwpcs]

Sounds like you would like the engines in stormworks. You can build a full ECU as well

[@planetagames5438]

and you have to desing the cooling system too

[@fernandoluis5117]

finally a worthy competitor for stormworks

[@GreenAxolotI]

Play Screw Drivers kAN, please

[@Skirakzalus]

I wonder if there will be some special transmission parts to at least help keep things small. I don't want there to be just pre-made gearboxes, but there needs to be a way to make them more compact.

[@luigirota7964]

Is a little generator engine (all open without cover), and I like the blue structural parts. This is only a test model but is super great and wit a free weel waigt at the final part 10:32 Mmm 🤔 another tipe of motor and probably a generator motor for another electricity ⚡️ test 20:30 Another one

[@BeanLord03]

Pretty darn cool, the soy design is so good.

[@StephenButlerOne]

Stick a turbo on that 5 pot and you have a T5. They are Fantastic engines

[@cat_lord5149]

Kan became the child at a candy store so fast lol

[@grummanschumann6475]

now all we need is ATG to make a synthesized audio system for this

[@larsrademakers6070]

V12 is gonna sound stupid great

[@dustinhensley2375]

Lean is hot, hot is fast.

[@meromere8339]

the volumatic effect is how much air fuel mixture is in the cylinder so 90 would be 90% fuel air mixture and 10% vscuum in real life this can go over 100% scince air is compresseble

[@nathanwilbrink2444]

i hope there wil be an update where the max rpm gets increased (and maby it would be fun if the bore and the stroke of the engine are adjustible)

[@raspyApostle]

Wait until Kan realizes he can make a boxer

[@KaHoMi09]

If you want to understand Volumetric Efficiency better, then driving 4 answers has got at good video explaining it

[@Tylerstace-smith]

Stands for volumetric efficiency. The simplest way I can explain it is It's pretty much the percentage of air going into the engine at said RPM versus its theoretical maximum amount of air 73% is terrible but an internal combustion engine Will never hit 100% volumetric efficiency unless you add forced induction. Then you actually go above 100%. As far as volumetric efficiency goes, that's why turbos are becoming so popular. I'm pretty sure the way this game is using volumetric efficiency is as like a horsepower. Limiting type thing 100% would be the maximum amount of power that that engine could make and then if you want it to make less power, you can dial the volumetric efficiency back to restrict airflow

[@TheMostUt]

Things of interest, possibly. Can you build an engine with a crankshaft with 90* offsets, so for a 4cyl you could fire 1234 (or something like that). Can you run the exhaust of one engine into the intake of another, and both of them work?

[@cuberznl]

yes and maybe if it just has a carb in between the pipes

[@ft3917]

i know some supercars dont use transmission anymore. they have a motor and a dynamo that drives electo motors by the wheels. because transmissons wastes a lot off energi and weights. koenningsseeegg also have a super capasitor to save up energi until you need it. i dont know iff the game can do the same as i mentioned. it can also be used for hybrid cars

[@NovumSB]

thats it im buying the game as soon as it goes on sale

[@NovumSB]

hope they add the option to modify bore and stroke

[@sovietaxolotl9389]

Nice

[@willie9899]

I wonder if this would support custom piston arrangements (like W, radial, etc)

[@thekingjdd]

@Gearblocks DEV If you lurk your game's YT video's, its been a little while since I've played but we still need outer ring gears for planetary drives. also I hope we see resizable pistons, and diesels. keep up the good work! 👍👍👍👍👍👍👍👍

[@Steinersgarage]

Different sizes is already halfway done. It will come with the full release with the engines. But yeah planetary gears is something I would love to have

[@thekingjdd]

@@Steinersgarage Cool, hopefully he adds diesel like engines as well. Dido the first thing I did was try to make a planetary transmission, only to realize there were no outer ring gears lol.

[@Steinersgarage]

@@thekingjdd theres nothing saying that these engines isnt diesel. people have made planetary gears with crowngears

[@thekingjdd]

@@Steinersgarage The dynamometer numbers and overall function say that these are not diesel engines. Ill take a look to see how people have gotten around the lack of ring gears.

[@timehunter9467]

I’d like to see a boxer engine being made, the piston movement might not be possible though? They mirror each other unlike a flat, so 2 crank shafts?

[@flabort]

Hmmm... I wonder if you can make a radial engine, then? I would definitely want to see the connections view of a V8, and the firing order, because that seems to be a bit more complex than the inline engines. I wonder how the exhaust will be handled, and how the fuel connections will happen.

[@Slez.]

That V12 sounds like it has a super charger wine

[@Shmeevers]

Hey, a bit ago i was able to come up with a way to make a manual trans by using a stepper motor to move a manual transmission with 2 buttons for 5 gears if that gives you any ideas

[@cobbleindistries]

sometimes i'm convinced kan does this stuff without ever looking at the screen...

[@rickveerman8576]

If this game would combine with screwdrivers it would be amazing. De internals of gearblox and the progression from screwdrivers 😮

[@ninjia7347]

Ahh yes 415 mph (667.8 kph) except this time with engine instead of electric motor

[@SirBrot]

I would like to see more excotic configuratiosn like a W12 or X12 or a rotary engine

[@user-wi8ly7rk4s]

@ Kan, if you think building engines in this is good you should try building in from the depths. I'm very surprised you never played it

[@Rararawr]

The parts were marked with sizes. I imagine once everything is working nicely they will probably add more sizes or parts. Little go kart might get a 1x1 cylinder. Or you can probably get stupid and put three 2 bore pistons in a V with two 3 bore

[@zzombiessniper4044]

So by changing an air fuel mix to be richer or leaner it can affect fuel efficiency and or power a richer mix will create more power at the cost of efficiency and being to rich will actually decrease power and by making the air fuel mix leaner it allows for better fuel mileage but if you make it too lean it would have problems staying running

[@Twisted1409]

Im surprised u not tried storm works maybe i missed that

[@TiagoTiagoT]

I hope he adds realistic electric motors too

[@nickoliva7313]

Wouldnt the different fuel air ratios be for different types of fuel, so maybe there will be different fuels when the update comes out

[@andrewbradley6901]

[@jackpastorello3438]

You should build like a drag racer or like a semi with a motors

[@erumaaro6060]

you can simulate a diesel engine by giving it high peak effisciency at a low RPM.
