Two cycle? Four cycle?? What is the difference? In this video Josh answers the question what is the difference between 2 and 4 cycle engines. What is the technology and reason behind the different engine types? And what is the STIHL 4-mix engine doing differently?

I appreciate the fact that this video gives a visual as well as a vocal description of the engine for both the 2 and 4 cycle.
Great information. Thank you

This is a great video! Perfectly explained in the simplest way for anyone to understand!

Great video. Love the cutaways! Now, not to be nit picky - and I know 2 cycle and 4 cycle have become part of the vernacular - but… they are both cycle engines (intake, compression, combustion and exhaust is the cycle.) One does it in 2 strokes of the piston, or one revolution. The other does it in 4 strokes of the piston, or two revolutions. So in a technical discussion, the terms 2 stroke and 4 stroke would have been more appropriate. Just a pet peeve of mine. I’m sure most people don’t care what you call them :)

Very informative, I got the information I was looking for 🙏🏿

Iv’e used both 2 stroke stihl trimmet and the 4 mix engine and i have to say that i really like the 4 mix engine and all it’s plus sides but no one can argue that the 2 stroke is lighter and more powerfull

Hi mate, thank you for your video! I just bought a honda single shaft UMK425 4 stroke. What i realized is when i turned it upside down to do edging, the engine didn't like it and it stopped. I assume most gardeners use a 2-stroke whipper snipper to do their edging instead? I bought that honda thinking it will be able to perform the edging feature rather than swapping to an edger tool. Or am i missing something?

The best thing I have ever done was to switch the pre mix fuel all of my equipment starts and runs better .

What is the 4 mix model equivalent to the fs 240?

[aaronmickels]

Is the km94r a 2 cycle or a 4 mix? Thanks for the videos!

You got a new sub man! Answered a lot of my wonders..😂

Help please. I want to purchase a new line trimmer. I currently have the Ryobi two-stroke 25cc. I am considering the Stihl FS56 RCE and the Echo SRM225. Also, is there a big difference between a 21.1cc engine and a 25.4cc? Any advice would be greatly appreciated. Thank you for your time.

You said it use gasoline. Is there a version that use kerosene?
Also isn't the 2 stroke ones vibrates more... so problem if you work it long hours?
Any sensorybto prevent it running n hit stones?

[smokey]

A 4 stroke will have more torque if and only if the 4 stroke has more displacement. 2 strokes have more specific torque.

Can you recommend a small outboard engine for a jon boat

What about long term reliability? I don't care about all the wussy being cleaner, lighter, or less noisy garbage. How will it hold up to years of extreme work?

[rickhelbig]

I rather change the oil on my 4 cycle Husqvarna trimmer than wear myself out trying to start a 2 cycle.

Why did the chain saw didn't start he ran out of gas

I came here on a quest to find the horse power difference between 2 cycle vs 4 cycle engine of the same cubic centimeters.. And if there is an equasion for discovery. This is what I need to know. You claimed "Everything you need to know" and this is probably the most fundamental information one needs to know. I did not hear where you explained the difference, except your generalized difference stating the 2 cycle gives more power. You also said the 2 cycle engines gives more RPM. For my current position a horse power difference or an equasion is crucial.

[Jimo]

my question is, does using a 2 cycle engine make you age faster. essentially you are sucking in and consuming 2 cycle oil a little bit at a time as you are using it. You probably drink a quart over a lifetime. can't be good for your health. what are your thoughts?

[aamikkalinin]

4 stroke is more reliable than 2 stroke
