they just do

Yep, they just do it.... :)

I guess you're wondering how do they get an engine that's in my car, into this small bike. Well although these engines work like the one in your car, they are very different. To start with, there's only ONE cylinder, as opposed to four or eight (or whatever) in your car. And the second big factor is that the engine in you car is at least 1 liter, probobly more. 1 Liter is 1000cc. Dirtbikes are usually up to 450cc. There are some over 700cc but definitely not more than a liter.

So there you go. You have a SMALL four stroke engine, now you can put it wherever you like. Answer If you go back in history a few decades, you'd that most, or nearly all offroad bikes were 4-stroke. They were heavy, and not especially fast, but then few offroad bikes were (fast). 2-strokes were dirty and didn't like running at low speeds as one must when riding offroad- the sparkplugs would foul up. Air-cooled two-strokes were prone to overheating and seizing, as well.

All of the Orion bikes use a 4 stroke engine.

A 2-stroke dirtbike will be powered by a 2-stroke engine and a 4-stroke dirtbike will be powered by a 4-stroke engine. For the same power, the 2-stroke will be a lighter bike. For the same weight, the 4-stroke will be a weaker/slower bike. The 2-stroke is likely to use more fuel and make more noise. The 4-stroke will run cleaner and quieter.

Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine

User Avatar

The answer is no. 2 stroke engine is different concept from the 4 stroke engine From http://xBrain.biz

EPA, 4 strokes are easier to ride because of engine breaking, and manufactures

Depends on if this engine is a 2 stroke, 4 stroke, or rotary engine. I assume you are referring to a 4 stroke as found in the vast majority of automobiles built today. The answer is, At the top of the compression stroke. The 4 strokes of a 4 cycle engine are:# intake/induction stroke # compression stroke # power stroke # exhaust strokeDepends on if this engine is a 2 stroke, 4 stroke, or rotary engine.

they suck ^^ First off let me say I agree. If you're talking about modern MX bikes (not those old crazy guys with road bike engines in dirtbikes) people always tried to race 4 stroke trail bikes with little success in 250 class. It was in 1998 that Yamaha developed the YZ400F and WR400F two high performance, water cooled 4 stroke bikes, one for tracks and one for woods. The bike was the begining of the 4 stroke revolution and the same 400 4 stroke engine went on to win the first AMA championship on a four stroke.

'a 4 stroke engine cycle' is usually what it is called...

No, 4 stroke. Two strokes were limited to Honda Motocross models, and MT series dual purpose bikes. They also offered a 3 wheeler w/ the Motocross engine.

No we can't use 100cc 4 -stroke dirt bike race against 85cc dirt bikes.

two stroke engine are better than 4-stroke engine in the following ways:- in 2 stroke engine there is only one revolution of crank shaft and in each revolution the power is delivered (in power stroke). thus it has a good mechanical efficiency rather than the 4- stroke engine. also the power we get through 2-stroke engine is double than the 4-stroke engine because of the same reason written above. 2-stroke engine is lighter than the 4-stroke engine because in 2- stroke engine there are no valve mechanism thus no push rod, cam-follower arrangment, rocker arm etc, thus 2-stroke engine is lighter than the 4-stroke engine. in 2 stroke engine in each revolution the power is delivered (in power stroke) thus torque is uniform, hence less torsional oscillation occurs.

2-stroke engines produce much more power than 4-stroke.

In a 2 stroke, every second stroke of the engine is a power stroke. In a 4 stroke, every 4th stroke of the engine is a power stroke. Knowing this, a 2 stroke has double the power as a 4, in the same cc

i say that a 4 stroke is faster than a 2 stroke

User Avatar

The best way to know if an engine is 2-stroke or 4-stroke, is to look for an oil spout. If the engine has an oil spout where oil has to be poured into, it is a 4-stroke. If the engine has no oil spout and the oil has to be added to the fuel, then it is a 2-stroke.

Petrol engine? 4-stroke, no. 2-stroke, some.

User Avatar

the 2 stroke has more rpm than 4 stroke because it has less moving parts and the cycles are faster because there is only 2 and in the 4 stroke there is 4

User Avatar

The quicker 2 stroke dirt bikes use a gas/oil mix. Most bikes you see on the road are 4 stroke and use regular gasoline.

User Avatar

It is possible to use 4-stroke oil in a 2-stroke engine in an emergency situation. You should not use this oil in the long term as it will damage the engine.

User Avatar

A four stroke engine has 4 strokes per cycle, whereas the two stroke engine has only 2 strokes per cycle. Since the 2 stroke engine has twice as many power strokes as a 4 stroke engine at a given rpm, the 2 stroke is capable of making nearly twice the power of a 4 stroke for a given displacement.

With a 2 stroke engine, you mix the oil with the gas. With a 4 stroke engine, there are separate tanks for the oil, and the gas.

A 1993 Honda xr100r would have a four stroke engine.
