I love that you did a slow-mo replay of the money shot Alex. Class!😂

[@WhiskeyOnFire]

Yo what a surprise! PREMIUM tuesday night entertainment

[@Kolomy24]

Did not expect such a reduction in pulsing from that,cool)

[@nicovandepol394]

You are using a breadboard to make the connections to the Arduino. From my experience I know that these connections do fail sometimes, very annoying in combination with PWM. Keep up the good work! Nice to see you back in business!

[@Margarinetaylorgrease]

Yea!! Breadboarding can be problematic. Get some PCB Way sponsorship 😁 and help from another channel.

Green seal is Viton. Good with fuel and alcohol. Blue is typically flouro-silicone and nitro is listed as mildly aggressive and would not be considered as an acceptable choice. That would explain those seals at the top of the video. I ran MFI extensively with methanol. Do over-spin the pump and use a by-pass. You may need an idle by-pass if you want a reasonably tame idle. I really like the EFI solution for THIS application, tighter range power band widths. If you want to pull the torque curve up really fast, then 100% MFI is the solution, which is much faster reacting than EFI. EFI is always BEHIND the instantaneous engine demands. It first reads, then corrects. So slow compared to MFI, which is instantaneous to engine demands. It's actually a highly balanced hydraulic system, and it don't get any faster than that!

[@marvinrascal3376]

Thanks for taking fuel in the face for us!

[@polaritDK]

[@itizmeca]

Reduce the pulse by increasing the rpm and use a belt reduction to the pump. You perceive more rpm as the solution already, so go with it. If it were me I would be operating a constantly pressurized reservoir of fuel, perhaps nitrogen regulated for the constant. But that is just me.

[@Keesvanrooij-o5h]

😊why dont you run the pump at high speed and create a fuel rail with constant pressure. You just return the overcapacity to tank. You can choose to keep a constant pressure or variate the pressure according to engine speed.

[@joncountegan5782]

Pump cavitation is an interesting phenomenon. Thanks for the upload!

[@ferrumignis]

The chamber adds smoothing for the flow, but also notice how much lag it introduces. At around 10:40 it took a couple of seconds for the nozzle flow to stabilise when you turned the motor speed down.

[@bradley3549]

Agreed!

[@ericschumacher5189]

I would suggest using an external regulator; this way you have a wider band of pump RPM vs. injector output (more granularity).....the difficulty is in sizing the regulator and it's opening pressure; ideally the regulator would be open well before the pipe powerband occurs (where fueling is the most critical)......I would look at aftermarket units from Summit, Jegs, etc. depending on the pressure range you wish to target, also routing the regulator return back to the gear-pumps inlet fitting will reduce pump cavitation at gear-pump speeds / not require as large of fuel lines to have adequate pressure control of the regulator, and much reduce the pulsing effect (the regulator acts as a mechanical damper).

[@EspenMiland]

En CO2 patron. Enkelt og funktionell løsning. Love it Alex🤟

[@christophercastor6666]

That line blew like it partied with Diddy. Cheers Mate!

[@tomheusequin1988]

To stop it from pulsating at low rpm, you need an ESC with sinusoidal startup and FOC (Field Oriented Control = feedback over the motor wires) , like one with AM32 firmware or a VESC. From my experience with RC rock crawling, a lot of generic ESC's do not have this function. There will also be a crossover from sinusoidal mode to PWM mode, which is barely noticeable. I would recommend one of the AM32 ESC's, cheaper, easier to program

[@mrpresidentm1]

[@bradley3549]

The accumulator solves one problem and introduces another. Huge amount of hysteresis to the system. For a WOT Bonneville run this is not perhaps a major issue. But something to be cognizant of none the less.

[@Relaxiknowarchie]

Looking good Alex, well except for the spraying of fuel everywhere. 😉

[@bostonbikebits6539]

Might sound weird - restrict the flow coming out of it - think like carb syncing gauges, they pulse like mad if you don't restrict the flow in the vacuum pipes. It can help even out pulses massively. Obviously you don't want to go so far that flow becomes inadquate.

[@AndreyNikolo]

Try real stand alone ECU...near to you (Sweden) should be MaxxECU. U can take smallest one - an Maxx Mini and it will be more then enough to drive ignition and fuel injection and data logging. The set up with Arduino is just to simple... Alpha N cycle ...TPS/RPM based map. With real automotive ECU you will have separate cranking , post start, idle algorithm and etc...temp, baro and whatever you think custom correction of ignition and fuel delivery.

[@bradley3549]

Rather than controlling the pump speed, have you considered instead controlling a very fine control pintle valve with a stepper motor and use a more traditional fuel pump/regulator arrangement?

[@michaelandersen4745]

Dear friend a recommend some tips and tricks for you to achieve max HP in your 50cc 2t engine. 1 get universal programable ECU 2t 4t for motorcycle 2 for alcohol a/f 6.5:1 MaX power. For gas 13:1 these value achieve max power. 3 find magneti Marelli six holes injector 12 v 4 use 16:1 mixture gas/oil or 30:1alcohol/oil. 5 use Castrol 747 for gas, shell advance racing M for alcohol 6 break in at least 5min at mid-range rpm. Try it and comment success. I'm former MotoGP 2t era 80' Have a nice day👍

[@jonlaws4493]

Maybe try a Trinamics motor controller unit to drive the pump.

[@jas-FPV]

Brushless motors are really bad at turning slow. Thats how they are, they need RPM Brushed Motors are better for turning this slow. Or you need a smaller pump

[@2000freefuel]

there are examples that are belt driven

[@jas-FPV]

@@2000freefuel sure, a reduction gear mechanism of any kind will also help

[@johngibson3837]

I was wondering that on the last video with low speed and brushless

[@extec101]

it depends also on what motor is used, as alex got an "outboard" motor they got more torque but look at cr car crawlers they got motors that can spin so slow we speak about like 100rpm or so. high winding on the motor is slower speed then a motor with less windings.

[@2000freefuel]

@@extec101 try a belt drive or add a planet gear reduction.

[@theshippingcontainergarage]

I bet your multimeter was reading correctly! Maybe try and run your meter on the arduino out and see if it reads right as a test. See if you can check the Ignitech PWM output on an O-Scope. When I did my ignitech RPM out on the neighbors scope it was spitting out a sawtooth signal instead of a square wave like it should have been. It was very hard to get my raspberry pi to read the signal since the signal was so weak. Check and see if the scope of the PWM signal is what you expect it to be. There was a language barrier when I emailed ignitech about it.

[@Pippy626]

Should have name the video taking the money shot of fuel for all of you

[@AmericanLocomotive1]

Just connect the ground and signal wire of the TPS directly to the arduino's 0-5v analog input. Don't bother messing around with a PWM signal out of the ignition system.

Why not run the injection with a carburetor, just have the injector turn on at 3/4 throttle

[@ewaysnow1310]

[@roberthawxhurst3717]

I am stumped on your developing fuel injection for as you state: Nitromethanol btw (Nitromethanol is simply a beginner's name for methyl nitrate) One things certain simply running Nitromethane in any engine not specifically designed for it is a complete waste of power, time, money and materials. Timing, compression ratio, chamber volume, incredible strong ignition etc etc are all new parameters that are unique to a fuel motor... Why waste time running nitro if the ducks are not in a row?. Finally can you just show up and run nitro in class racing?.......

[@damnthiccassboye7138]

mount it directy to the engine ?

[@STYX-a-Lot]

THIS IS THE BEST WAY I CAN EXPLAIN IT… Alex, remember when for no seemingly apparent reason a couple of years ago, you just dropped everything and started building a log cabin by hand. That was very strange, and I may not understand it, it was important to you at the time. Well, when I first started watching your video and you’re talking about pulses, it made me wanna just jump up and say, hey, if you were using hydrogen gas, all you have to do is open a valve. So, naturally everything in my mind jumps back to my engine design, and it wouldn’t be out of the ordinary if you just stopped everything you’re doing and started a new engine design for seemingly no apparent reason. I wouldn’t be mad at you. But, just think, you could 3-D print the Torus, or donut shaped housing for the engine, and that would be most of the struggle done. It’s just like a two cycle engine engine it except it goes in a circle instead of back-and-forth. This would allow for the worlds first HCCI engine. When you think about it, hydrogen combustion expands 10 times faster than gasoline, so already you’ve got 10 times the power for a smaller package. Next, you have HCCI that all goes off at once, and you’re able to turn 100% of that to torque instead of a mere 15% that you can get from a crankshaft. My tiny engine design is all about extreme power. There isn’t anyway that you can use all of the power. It’s all direct torque. There’s no timing to deal with. There’s no carburetors, and no injectors. There’s no electricity to deal with. There’s no pumps, there’s nothing except a valve to turn to release the hydrogen gas. When one 2 headed piston run into the back of another two headed piston, they won’t make contact because there is an air spring between them, which is the charge of air and hydrogen, and all of the forward momentum of the first two headed piston has passed into the second two headed piston. So, no energy is lost like in a reciprocating piston. A crankshaft engine is limited in RPMs because the weight of the piston increases exponentially at higher RPMs until the connecting rod breaks, not so in my design. Mine is equal to a free spinning wheel. If you will, please revisit my channel, and read in the comments how the design works as I have written it in words. Hopefully, you still have the design I sent you three or four years ago that fits into a bicycle wheel. That engine design alone that was only 4 inches in diameter, would create so much torque and horsepower, that no one would believe that all that power is coming from such a small engine. You have got to think, a combustion that all goes off at once instead of propagating flame front, acting directly on a piston that goes directly around the output shaft with no oblique, crankshaft angles, expanding 10 times faster than gasoline, and the engine having no seals because it takes time for gases to escape past a crack, and HCI happens all at once with no time at all, and you’ve got a hyper mega ultra extreme power engine that cannot be improved upon. It is patentable, it is marketable. It is feasible, and it never wears out because it has no touching parks, except for the bearings which can be made of ceramics and virtually last forever with no maintenance. Just something to think about, so please if you get the time, revisit my channel and read the comments. Thanks, Alex.

Next, for the transmission, which is infinitely variable, constantly variable, very few parts count, reliable, compact, lightweight, and simplistic, all you need is a basic planetary gear set whose annulus is allowed to spin freely for neutral. It carries magnets that pass stationary wires, and produces electricity that if left unused, you have neutral. When you start to use this electricity, it puts resistance against the annulus on the planetary gear set, and the lowest ratio is achieved. The more electricity that you use, the more resistance on that annulus, or ring gear, is placed until the final 1:1 gear ratio is achieved. Where do you send the electric power? You send it to a front electric wheel motor. They already have those, so you don’t have to worry about trying to create one. how much energy you send to that front electric wheel motor determines how much engagement is deployed to the transmission. It is meta-genius, and as elegant as the gods of physics allow. So, be the first and the last to impress the world with the world’s last engine design. There’s nothing stopping you. Sometimes it’s OK to just drop what you’re doing and listen to the gods. They already know where you’re trying to go. Peace, get you a piece. Let her rip tater chip.

[@STYX-a-Lot]

It’s like any other two-stroke engine, except instead of back-and-forth, the piston stop and start as they go around an a circle pattern inside of a donut shaped housing. The exhaust and intake come through the arms that hold the pistons that travel in the circle pattern. Intake comes in one face of the hockey, puck shaped engine, and exhaust exits through the other face of the hockey puck shaped engine. This shape allows it to fit inside the wheels. The front electric wheel motor also functions as regenerative braking, but instead of charging a battery, it charges a super capacitor, so that 90% of the energy is captured and released as opposed to the mere 13% when you use batteries. The technology speaks for itself, and is self evident. Anyone who has ears to hear and listens, will have the truth, jumping up and down inside of them. They will jump on this thing, and never wish to get off. it’s like that. So, hold on tight, buckle up, and get ready for the ride of your life. Peace out, bro. I expect only the wise to actively respond.

[@STYX-a-Lot]

I had printed more, but I don’t see it there now, so I guess that’s for whatever reason, it was taken down or something I don’t know. But it was describing the simplistic infinitely variable, constantly variable transmission that goes with it. I have no idea why it was taken away.

[@STYX-a-Lot]

To keep things simple and prove it out, all you need is a very small model. It won’t take very much time at all. Something is small as a cox engine.

[@STYX-a-Lot]

Then comes the issue of how to start it and stop it. While it’s running, it loads a spring to stop it, and to restart it, the spring is released, and both sets of two headed pistons are spinning freely in the housing. Then, a cam lobe obstructs the pathway of one of the Pistons sets, and it stopped abruptly, and compression occurs to induce HCCI. That means that this engine "can be" purely mechanical with no electricity needed until you get to the transmission. That means that this engine would run even after an EMP blast. I friction brake could be used instead of the electrical resistance in the transmission… but, for commercial use, you would want to use the electric transmission. That is pure efficiency, and there are no brake pads to wear out, and there are no touching parts.
