Rata2 DOHC. Pakai langka kecil sih

You can always tell it's AI. "Nitromeething". I am concerned about the days when we won't be able to tell. AI. needs to be kept stupid.

If this can completely replace the cooling system for an engine, and thus be variable to maintain an ideal temperature, then this would be a likely next step in engine design.

Talk it to CBR250RR 1990 year, with 22000 redline

Smokey Yunick said said 2 stroke is the way to go 😊

I will always be crossplane fan its my favorite 👌🤤

One thing I've never understood about engine design is that the higher revolutions are almost never needed in everyday driving and also affect fuel efficiency so why be concerned about higher revolutions. Driving a vehicle above 70mph is illegal in most States so why engineer a car that can reach 100mph. Another thing I don't understand is why aren't all electric cars built with a multispeed transmission which should be able to increase range from the same battery.

Supra fit

how does this solve the intake valve getting gunked up by carbon deposits from PCV valve

None of this is new!!

Nice presentation, but you should learn to spell "mixture".

An amazing concept. I wonder if having several pistons in line and minaturisation of this could be used as a compression ignition (Diesel) impellors for radio controlled 'jets'.. Castor oil/ethanol can be used as Diesel fuel. Vroom! Nice one. 🌟👍

This is proof push rod engines are king ,and overhead cam engines are inefficient complex peices garbage

FORZA?!🤣🤣🤣🤣

"Transition"? I'm pretty sure we're far from transitioning from carbs to fuel injectors. I mean fuel injection was in almost 100% of vehicles by the late 1980's. Dare I say mid 1970's for luxury vehicles. Benz did not create the, "Otto Cycle", which is not Benz....and you're showing a 2 stroke engine, not a 4 stroke.

You wont get valve Float

i think roter valve is more efficient no fighting valve springs like the ducati desmo

Back in the 1980s, Orbital made a 2-stroke engine with a supercharger. The exhaust port was valve-less, on the side of the engine. The intake had a reed valve; as the pressure in the cylinder dropped ('cuz exhaust gasses escaping out the side), the supercharged intake air pressure overcame the in-cylinder pressure and pushed the valve open, admitting fresh air / fuel into the cylinder. Fresh air / fuel in through the top, exhaust gasses out through the lower side. When the cylinder rose enough to cover the exhaust port, the pressure in the cylinder rose and the reed valve closed. It was pointedly setup such that about 2/3 of the (upward) cylinder stroke was compression, about 2/3 of the (downward) stroke was power and the remaining 1/3 of each (near BDC) was overlapped exhaust / intake. Emissions were relatively clean, because there was no oil being burned. Given this was developed back in the 1980s, and Mazda is just adding cam-driven intake and exhaust valves (old news) and direct injection (old news), I'm surprised this was considered sufficiently novel that it would qualify for a patent.

All roads lead back to steam engine

and what will be next? an 8T engine???💀

Great video and great animation!

It appears to me that the impellers in the animation of the supercharger are rotating in the wrong direction.

Basic function of a carburettor is to mix fuel and air with a predetermined air fuel ratio

Cool engine, the biggest hurdle is emissions

I was about to patent it. Damn you Mazda 😡

Mazda is the last true car maker in the mass production.

For all my fellow 2 stroke nerds out there here is a tiny fun theory, that engine in the digital rendering with the gold barrel and head appears to be a very similar copy of the kawasaki krr150 or zx150 or ninja 150rr, super kips from Thailand. Great bikes, I have had 2 or 3 of them and would buy another if I had the chance. Also closely related to the kg150

Cheap Ai voice doesn’t add to credibility

No multiple overhead cams or variable valve timing. Might as well use all that forced induction to make it two stroke for bonus points and more fun.

i am thinking here, if the engine use a variable cramshaft, it can alternate between modes Miller/Atkinson 4 strokes: Kalm Otto regular 4 strokes: Need more power 2 strokes: Lets gooooo

idiots. its just a 4 stroke with a supercharger. that s it

JegmTech VCR 2 stroke impulse technology is superior to this 2 stroke Mazda architecture. Not even close.

"More Superior"?? Do you speak English? Do you know what "Redundant" means?

End up with about same number of detonations per minute. Double the detonations per revolution, but cut max RPM in 1/2. Adding alot of complexity and weight . . . End up with an engine that is about the same size and weight and power. Remove 2 cylinders and add a supercharger . . . Back to where you started.

The supercharger in the animations is running in reverse.....So it would be sucking air out of the engine You confuse air fuel ratio and compression ratio. Conventional petrol AFR is 14.7:1. Diesel is a whole lot higher than the 15:1 you claim, as diesel's are a variable AFR engine, with no restriction in inducted air flow and engine output controlled by fuel delivery. Compression ratios are typically 10:1 for petrol and 18:1 for diesel's And the camshaft rotates 180° while the crankshaft rotates 360° in a conventional 4 stroke Otto engine If you can't even get the basics correct, it casts doubt on the entire presentation

I’m kinda surprised it’s actually quite clever. And it looks pretty much worked out

⬆️HONDA ➖YAMAHA ⬇️SUZUKI

A patent means neither that it's actually good and useful nor that it's guaranteed to be successful.

I dont see the point... Split single 2x125 VS 1 single 250 for example ???? They really wanted to test the limits of unpracticallity and unreliability 🤦

They are harsher mechanically requiring expensive valve service rates at more than double those of a spring system. This is why Ducati just abandoned them after decades of Desmo being iconic part of their brand. Changing to springs increased the valve servicing interval by 60,000 kilometers.

False info

I race RC cars and fly RC planes using IC engines, which are true 2 stroke nitro methanol and reach up to 30,000+ rpm which is insane and sounds deafening. I guess this engine will sound like a deisel engine running at 1800 rpm max which would petty boring.

Using a Comprex (Pressure wave supercharger) instead of a root blower would further enhance efficiency, since it requires little energy to work, and exhaust gasses leaking into the fresh air is not a problem for this engine.

Regarding the 700bar compression pressure, I call bull shit. That would be over 10000psi. I would believe 70 bar, still over 1000 psi, but I think detonation would be a problem. Regarding the lower rpm, just like with diesel engines, the lower rpm would go hand in hand with higher torque at the same rpm, so no problem there.

From the For-What-It's-Worth department: All this talk about how much faster these cars would be if only they were allowed overhead cams, rotary engines, rocket engines, no rules at all, etc. is fine as long as people understand such talk is pure fantasy that will never happen for several reasons. Safety is #1; few drag strips are long enough to allow a stop from more than 335+mph. That's 500 feet PER SECOND. It's the primary reason NHRA switched to the 1000 feet racing distance for the nitro cars back in 2008 after the death of a prominent driver who ran off the end of a short track and collided with a camera truck. Most can't be extended and wouldn't be if they could. Tire technology is another; Goodyear could build a stiffer tire for more speed but then it wouldn't contain 11,000 horsepower. The tech to build a soft tire that will handle that much power during the run and hold up to speeds of, say, 350+ does not exist and neither Goodyear nor any other manufacturer has plans to develop one that will. Aerodynamic forces that affect everything from the rear wing, front wing and the chasssis are astronomical at those speeds and they don't increase on a linear scale. Keep upping the speeds and you wind up with a death trap that's totally unsafe to drive. I could post dozens of chassis failures that destroyed cars, injured or even killed drivers due to metal fatigue at 330mph. NHRA won't have it; drivers wouldn't drive them anyway. Who could blame them. We may not have reached the end of how fast and quick a dragster COULD go but we're maxed out on how fast and quick a dragster SHOULD go. And if you're not satisfied with an impossibly loud machine that accelerates from 0 to 330 in 3.6 seconds while shooting flames 10 feet into the air, you need to find something else to do with your time. Wild speculation is fun but in this instance that's all it is and all it will ever be - speculation. RE compression ratio: It varies, usually between 6 and 7 to 1, used as a tuning tool the same as the teams add or take away blower drive, timing and clutch application. A marginal track requires less power in order to maintain traction so in go some lower compression pistons or slightly thicker head gaskets along with anything else to dial back the power. If it's a gorilla track and conditions are right, then the process goes into full-boogie mode.
