Everything You Don't Know About 2 Stroke Engines 🤯

In this video we analyze how a 2-stroke engine works in 3D:
Piston types
Reed valve and rotary.
How direct injection affects.
2 stroke engine exhausts.
crankcase compression
Oils, Etc.

I liked the crankcase case compression ratio explanation never thought of that!

The most humble face reveal without asking for likes :) liked

[@cheesebusiness]

Where?

[@nascer2979]

Thank you so much for such a great video! I'm a two stroke freak and I waited so song for this video 😁
Could you make a video about heavy duty engines and its durability? I would be greatful 🥰

[@alimechs]

Good update keep it up the good work 👍👍

[@ATomRileyA]

Great video really explains it all so well.

[@TheBMWDrifter-sb2cy]

Your videos are the type of videos I didnt know I needed, this stuff is really cool. Please continue!!!!

[@AuMechanic]

Good animation, covers it mostly.
A few points missed but nothing major.

[@pauloconnor7951]

Yeah not too shabby !. Where in Au are you ?

[@repairman22]

Hi. Tell me those points so I add them in other video. Thank you!

[@AuMechanic]

@@pauloconnor7951 In Melbourne, Sthn Burbs, grew up here.

[@AuMechanic]

@@repairman22 A bit too lengthy for the comment section.
I do 2T vids that go down the rabbit hole on each topic so maybe look over those if you like.
I sent some via your email.
But as mentioned your vid covers the basics fairly well.

[@CaseyW491]

Hey, love your videos! I teach equipment operators for a trade school. Do you mind if I share some with my students and credit you? Some exposure.

[@repairman22]

Sure. No problem.

[@ovalwingnut]

GR8T animation! See, this is what the Interwebs are acutally for You R the "Two Stroke Engine Whisperer"

[@cleonwallace2267]

thanks bro this is perfect keep it up and keep us updated

[@repairman22]

Thank you!

[@alanstrong55]

FYI: Must mix the gas and oil. 2 stroke engine oil mandatory. The motor is louder. Just the right motor for a dirt bike. Climb that hill. Have fun on an open field. Yamaha said it is all right. Enduro!

[@Eduardo_Espinoza]

There are cleaner lawn care 2t engines that leak clean air in front of the transfer ports so it's clean air 1st then a/f mixture, since the 90's-Present (RedMax: Strato-Charged). :)

[@pauloconnor7951]

Really ?. Who does that please ?

[@billmalec]

Glad you say 2 stroke and not 2 cycle.

[@gigabytegb]

Fantastic! I will come back to make questions, and more questions to develop simplified and cheaper electronic ignition (or piezo atomizer😅) and injection, with cheaper sensors and microcontrers like ESP-32, photodiodes for monitoring temperatures like EGT, and solve my problems with stability (and share with you) here in Brazil with this admirable trash tools!

[@quietknight8250]

Two words, Schnuerle scavenging.

[@andrewallen9993]

My Jawa 350TS has 3 rings as a 10:1 compression ratio.

[@matthewfredrickmfkrz1934]

Effects of port timing

[@RIPPERTON]

Direct injection doesnt work because the bottom end runs too hot without fuel cooling.
KTM have already proven that.

[@Not1Edit]

The animation shows the piston below the intake, but this never happens on 2 strokes

[@repairman22]

In any part of the video, the piston goes under the intake port.

[@Not1Edit]

@@repairman22
Yes, & it's wrong.
The piston top never goes low enough to open the intake, it would defeat the scavenging if it did.
Look at any 2 stroke, Your video is wrong!

[@franckn8338]

​@@Not1Editsorry, if the piston doesn't open the fresh air intake port, nothing will happened.

[@Not1Edit]

@@franckn8338
YOU HAVE NO CLUE HOW A 2 STROKE SINGLE CYCLE ENGINE WORKS, & IT SHOWS.
INTAKE VACUUM IS CAUSED BY THE PISTON GOING UP & AWAY FROM THE INTAKE PORT WHILE COMPRESSION OF THE CHARGE THAT CAME THRU THE TRANSFERS IS ON IT'S WAY TO COMBUSTION.
AS THE PISTON GOES DOWN ON THE POWER STROKE IT IS OPENING THE EXHAUST TO LET SPENT GASSES OUT.
WHEN THE EXHAUST IS ALMOST GONE THE TRANFERS BEGIN TO OPEN, & SCAVENGING TAKES PLACE DUE TO THE DECENDING PISTON PRESSURIZING THE LAST INTAKE CHARGE & BLOWING IT OUT THE TRANSFERS, SWIRLING AROUND THE COMBUSTION CHAMBER & OUT THE EXHAUST BEFORE THE SOUND PULSE FROM THE EXPANSION CHAMBER HOLDS IT THERE & THE PISTON RISES & CLOSES TRANSFERS & EXHAUST PORTS AS THE PISTON COMES UP ON THE NEXT STROKE DRAWING IN THE NEXT INTAKE CHARGE FROM UNDER THE PISTON, NOT ABOVE IT.
THE INTAKE IS NEVER ABOVE THE RINGS IN A 2 STROKE.

[@jan-akelofgren7547]

@@Not1Edit Well it happens in a 50cc engine called Huskvarna Flinta. The aftermarket crankshaft is wrong, they have increased the stroke by 2mm but only downwards, so the piston opens the intake port.

[@Blanchy10]

Full of shit for any given capacity most two strokes rev lower than four strokes!

[@trxtech3010]

2 Strokes are such garbage,
