A two-stroke, or two-cycle, engine is a type of internal combustion engine which completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. This is in contrast to a "four-stroke engine", which requires four strokes of the piston to complete a power cycle. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time.
Two-stroke engines often have a high power-to-weight ratio, usually in a narrow range of rotational speeds called the "power band". Compared to four-stroke engines, two-stroke engines have a greatly reduced number of moving parts, and so can be more compact and significantly lighter.
The first commercial two-stroke engine involving in-cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later two-stroke engines, his had a separate charging cylinder. The crankcase-scavenged engine, employing the area below the piston as a charging pump, is generally credited to Englishman Joseph Day. The first truly practical two-stroke engine is attributed to Yorkshireman Alfred Angas Scott, who started producing twin-cylinder water-cooled motorcycles in 1908.
Detroit Diesel Corporation (DDC) is an American diesel engine manufacturer headquartered in Detroit, Michigan, USA and a subsidiary of Daimler Trucks North America, itself a wholly owned subsidiary of the German Daimler AG.

A car engine uses a four-stroke cycle -- how can two strokes accomplish the same tasks? Learn all about the two-stroke engine, where it's used and how it compares to a four-stroke.
Thank you guys you are awsome. Want to give a credits to all which videos i use in compilations. At this moment im back on bike and started racing again after broken spine(twice) :) Still enjoying to ride and still can race. I Hope will get some camera and start doing vlogs or races report! AGAIN WANT TO THANK EVERYONE FOR SUPPORT! Leave a comment,share video,like.. Good luck and stay updated here or on facebook page https://www.facebook.com/motocross4ever71/ RIDE SAFE!
I ride a two-stroke along with my buddy and his son. I get yelled at for being a complete jerk and am generally obnoxious on my two-stroker. Two-strokes are known for being superb enduro bikes, primarily because of their light weight. Combined with more modern resonator pipes that give them a larger amount of torque, these bikes are excellent off-road machines, ready to conquer whatever it is you can throw at them. However, there are some disadvantages to riding two-strokes that riders need to keep in mind. Because two strokes use the crankcase as part of the induction system, oil must me be mixed with the gasoline in a two-stroke engine. Without doing this, the engine will fail incredibly quickly. Mixing the oil with gas also reduces their fuel economy, meaning that a normal tank of gas...
This one's for all the two-stroke fans out there. The first race of the day at Glen Helen was the FMF Two-Stroke Invitational, and Sean Collier (#207) earned the victory on a KX500 against the likes of veteran Mike Brown (#3). Turn up the speakers for this clip, and listen to those sweet, raw two-stroke sounds.
Evinrude 300XP -91 After a few hours in the workshop.. The expansion chambers are "home made" by hydroforming. The original exhaust is milled away and the engine block is filled whit plastic. This engine will get electronic fuel injection and will not be used in a boat.. www.facebook.com/rudezon

Two of New Zealand's fastest motocross riders Hadleigh Knight (2017 Husqvarna TC250) and Brad Groombridge (2017 Suzuki RM-Z450) attempt to settle the age-old argument of two stroke versus four stroke at the 2016 Acerbis 4 Hour cross country in Taupo, New Zealand.

Once a racer, always a racer. We join former pro Neville Bradshaw as he takes on the first round of the new Maxxis British 2 Stroke Championship at the historic Canada Heights. We dig deep to find out what it is about 2 stroke racing that tempted the hardy veteran racer back behind the gate. Watch to find out how Nev got on on board his 15 year old CR 250 against the might of the latest 2 stroke machines. There's truly no better racing than 2 stroke Motocross racing. We hope you enjoy this 2 Stroke Motocross documentary! If you want to see more videos like this let us know in the comments, like this video and subscribe to our channel!
Do not try this at home! It's very dangerous. Some driving around with the wonderfull Italian 1990 two stroke Aprilia AF1 Sintesi Futura, really fast for being only 125cc engine. Ofcourse tuned a little bit. Recorded at the old Södertälje road, Stockholm, Sweden. Hope you enjoy..

HI Thank you for clicking through to this video on my 12 reasons why a two stroke cycle engine may bog down. I as well as explaining some key reasons for bogging down of the engine, I really wanted it to be a Crash Course on the workings of the Carburettor also. By creating the video in this way I hoped that the content will be remember much better due to a detailed understanding of what is going on inside the Carburettor. I didn't just want to tell you what the problems were causing Bog Down, I wanted to educate and show you why! I hope you like this video and please do subscribe if you would like to. Thank you again to all of my existing subscribers. Many thanks indeed Craig
The first video in probably 2 or 3. In this video we look at the very basic concept of how back pressure works in 2 stroke expansion pipes. Firstly I talk about pressure waves, and show a simplistic version of how a pressure wave travels through a directional flow.
The two stroke story continues. South African racer Neville Bradshaw continues on his quest to become the British Two Stroke Champion. He must do battle at the epic Hawkstone park in order to lay his claim for the crown. Meanwhile, his addiction to the smokers has led to the purchase of a 1997 CR125. We join Nev for a face melting session on his new toy. Why you ask? FOR THE LOVE OF 2 STROKES!

So really motherfucker gonna fuck with me?
I'd love to be the fucker
If the mother in charge is jade
Every dude wants to be the king
But they don't know
The king is fat and old
He dim sings na na na
The queen tiptoes to the jack
She has got pink lips and fridge
She is the conjuction ring
Between female and human being
Disenchanted, if you say princess
She knows you are calling her a doll
Picture a girl whose first ambition is not designing problems
Uninhibited, Unrepressed
Eight arms to slap or hold
If you say sweetness,
