I know I'm necro posting a video from forever ago, but honestly, I'm not a car guy, never have, never will be. But seeing these things in this manner really really makes sense in a way that math and fluid motions doesn't for me. Thank you so much for taking this trip out there and doing this with these guys. It's amazing because every person you talk to on your channel is so engrossed in the project that they're working on. It just sucks when its "proprietary knowledge" and they can't share it.

I see the secondary spark during the exhaust stroke. Is that on purpose to burn off any of the gas that didn’t get burned during the power stroke?

Another interesting thing is the useable range of the power stroke. About 12 deg, after TDC is when you want peak pressure, About 12Deg before BDC is when you run out of leverage to put energy to the crankshaft. So you light it before TDC in a manner to reach peak pressure about 12 deg after. Think of pedaling a bicycle. At TDC you can put all the pressure you want on the pedal and not move the wheel. Once the pedal goes past TDC your downward pressure can be applied to start turning the crankshaft.

You never mentioned the waste spark. The spark was initiated with every revolution of the crank but only used to light the air fuel mix every other revolution. Just before TDC on the exhaust stroke, the spark happens again but not used.

23:18 I found it so interesting how it sparks twice per cycle (cycle being four strokes). The first spark does not light anything because there is no fuel in the engine (I think). I wonder if there is a purpose for the two sparks or is it just that you can't get it to pulse that slow.

I disagree with your suggestion that the misfires were from the lack of exhaust gases in the cylinder after the exhaust stroke. I believe the misfires were from the inconsistent engine rotation at idle that produced and inconsistent mixture from the carburetor because of the single cylinder operation. I bet if you install a heavy flywheel on the engine it would run better and I bet if you load the engine the misfires would go away like a lawn mower engine. Single cylinder engines are notorious at idle or low RPM because the rotation of the engine surges and causes an inconsistent fuel mixture, but as soon as the RPM is increased and load is increased and the consistency of the engine rotation is optimized and the fuel mixtures are consistent everything the engine runs great. When you increased the back pressure on the exhaust of your engine and it ran better that's because when you restricted the exhaust you were creating a load on the engine, hence it ran better.

Back Pressure is just a Pulsing Wave front. Manipulating (Tuning) the Volumetric area and or Shape of the exhaust pipe facilitates the Evacuation of the cylinder gasses. You had it at the Scavenging comment. Imagine the RPM as a frequency and the Exhaust pipe as a wind instrument. Even though there is Negative pressure in the Atmosphere, The Exhaust Pipe is still Under pressure as the Pulses stack up and Compress inside the Exhaust pipe, (This is why exhaust leaks can happen in an open ended pipe.) So, If the RPM frequency can be matched to the Pipes length and Volume, the Pulse front can act as a vacuum on the Next Exhaust cycle thus helping "Pull" it through faster by facilitating a "Relative Negative zone" behind the Pulse front. . This can be use to pull more power for any given RPM range as all combustion engines are just air pumps.

Great video, one piece of information tho, the best spark / ingition timing is measured by the torque the engine produces or the knock limit of the fuel, not the the AFR.

I love engines. I’ve been mesmerized by combustion engines from the time I was 7 years old. I still have a hard time understanding advancing the timing to the point of detonation. And being able to change the timing at the cam placement. Or at the distributor. It’s amazing how tbh can make all 4 pistons work together. How does 1 or more not get a little out of timing. Idk

Maybe. Either way, thank you Destin and all involved, great video and always inspirational, even though I still think the combustion engine is part based on wizardry and alchemy.

When I was a kid rebuilding lawnmower engines was something I did numerous times. I always wanted to see what the combustion chamber looked like when the engine was running. Now I know. Racing engines use tuned exhaust systems. So do high performance factory cars and trucks. Butter face lol (that's old school :o) ). The governor on the red engine came from steam engines. The term balls out came from the balls on the governor on a steam engine running at maximum RPM being at maximum extension. I will never complain about my mini lathe again. They made one 4 cylinder engine out of 4 1 cylinder engines, with smaller equipment than I have. It's not the lathe, it's the operator...

This kid has as lot of incorrect statements about how engines work. Why we use advance timing, why "knock" happens... Hes great with the electrical side and the basic mechanical side, but theres some misconceptions here. Theres more than those two, but im not gonna sit here and write a mechanical engineering thesis in a post, so will cover those two... With advanced timing, the aim is to ignite the mix just before TDC, then the flame front will accelerate as compression continues to press the air and fuel molecules closer together, increasing efficiency. The chemical reaction then continues as the piston travels back down, generating heat, which makes for more volume (you know the drill there). When this golden point occurs depends on the engine geometry from combustion chamber to deck height, to dwell time and piston velocity, and other factors like fuel octane, etc... And because of that, it also changes with RPM, because the piston begins to move faster but the flame fronts remain relatively the same velocity regardless of RPM. This is why we use variable spark timing. Variable cam timing is done for different reasons but it ties into this spark timing system. As for knock, ping, preignition, or detonation (it goes by many names), it's not because you advanced timing too much. Or well not solely because of that. So what happens? Well he got the octane thing correct. Fuel with lower octane is more unstable but has faster flame fronts. Higher octane is more stable, but has a slower flame front. As you increase compression ratios, which are heavily influenced by the cam and it's valve events (dynamic compression vs. static compression), the air fuel mix heats up, because its compressing. In a hot engine, that heat can become so great that the mixture ignites on its own, a bit like a diesel engine. If that occurs at just the right time and place in the chamber, the spark plug fires, and its flame front meets the preignition flame front, creating a concussive shock wave, which is what you hear when you hear a ping. The energy from that occurring can crack pistons, or bend piston rods because the fuel ignited so early that the engine couldnt turn but the other cylinders tried to force it. Bent rods usually only happens in high power engines though, high torque engines. So while spark timing is a factor, thats not why knock occurs. And for those wondering, because this comes up a lot, no you should not put 93 octane in your stock 9.5:1 static compression engine, regardless of the cam being used. Doing that has no benefit in that kind of engine. You spend more money for more stability that you dont actually need, while causing a slower flame front, which can kill power and cause hesitation. We use premium or ethanol fuels in engines around or above 11:1 static because, without it, we would get knock because the compression is high enough to ignite low grade fuels. They, however, dont lose power. Because compression is so high and the molecules are so close together that the flame front meets or exceeds the velocity in a normal 9.5:1 engine with low grade fuel. So no, you dont need premium in your car unless you have a 6.4L or supercharged 6.2L Challenger, or a Corvette or something in that ballpark. Refer to your owners manual and follow that. If you live in a super hot area like a desert, or Florida, you might bump it up one fuel grade because of the extra heat, but dont use 93 if it says 89 is required. The fuel octane callout in the manual was calculated by the engineers that designed the engine, follow it.

I can't believe I haven't found this video before now! It's awesome!! As for the end, where you guys talk about the positive pressure still when the piston is still going down, does that not mean that the engine is very inefficient, in that there's too much fuel to burn in the time of the half cycle of the engine? Ie: even if it is burning with the right fuel:air mixture, there's just too much of it to burn in that time, and so you're spewing out fuel still burning, and wasting the gas expansion?

Jet engine, recip IC engines all do the same thing: suck, squeeze, BANG, blow!!!! Rather than a piece of sacrificial acrylic plastic maybe they could use a thin piece of tempered glass similar to the somewhat flexible, tempered Gorilla Glass used for cell phones. This would be more resistant to heat damage and it would also be resistant to solvent damage like what would happen with gasoline. The thick acrylic plastic piece would still be needed to prevent over flexing and shattering the glass.
