Why 2 strokes engines are lighter than 4 strokes engines?
Gurvindersandhugp787...
There is no oil resivoir holding oil that weighs around 1.7 pounds per quart. A 2 cycle engine also does not have valves which a 4 cycle does. All this makes the 2 cycle engine simpliar and lighter.

Why do 2 stroke engines sound different than 4 stroke?
Because 2-strokes fire on every turn of the crankshaft while 4-strokes fire on ever 2nd turn of the crank.
Do all 2 stroke engines have govoners?
no mostly torbo two strokes have govoners
How many strokes for diesel engine?
Diesel engines can be built in both 2-stroke and 4-stroke
Are gasoline engines are -stroke engines?
Most gasoline engines are four stroke engines which is also known as the Otto Cycle. 1) Intake 2) Compresson 3) Ignition 4) Exhaust (four strokes)
Are the Yamaha 350 Trials and 250 Trials 4 stroke or 2 stroke?
Current XT and WR models are all 4 strokes. Cross models YZ have engines in 2 and 4 strokes.
Most gasoline engines are what stroke engines?
Most gasoline engines are four stroke engines which is also known as the Otto Cycle. 1) Intake 2) Compresson 3) Ignition 4) Exhaust (four strokes)
What is the source of energy for the strokes other than power stroke in 4 Stroke engines?
There are intake and exhaust "cycles". A 2 stroke goes so much quicker because it it simply intake exhaust, generating power rather fast compared to the 4 cycle engines making power in the cycle half as often. The valving on 4 strokes allows for many things but they are never quite as quick as two stroke engines.
2 stroke vs 4 stroke?
On a 2 stroke engine, each cylinder fires every time the piston comes up. On a 4 stroke engine, the cylinder only fires every OTHER time the piston comes up. 4 stroke engines have 4 strokes: Intake, compression, power, and exhaust. 2 stroke engines complete these cycles in only two strokes of the piston by use of ports in the cylinder walls. 2 stroke engines usually produce more power for a given weight/size. But, in gasoline engines, 2 stroke engines are typically less efficient (use more gas) and have much higher pollution levels (note: some newer "direct injection" 2 stroke engines do much better on pollution levels than the typical 2 stroke)
What is better a two stroke snowmobile or a four stroke snowmobile?
4 stroke is better than 2 -more torque last longer that is why gm stoped making 2 stroke diesels
What is faster two stroke or four stroke?
It is generally accepted that a 2-stroke is more powerfull than a 4-stroke - for each full cycle (induction, compresion, ignition, exhaust) a 2-stroke engines crank rotates twice and a 4-strokes engine rotates 4 times. Therefore, for each 4-stroke Bang you get Bang, Bang from a 2-stroke! 4-stroke engines are far more efficient though and 2-stroke engines are getting close to being legislated out of existence (we have just lost 250cc Motorcycle GP racing in preferance for 600cc 4-strokes).
What is lighter 3 grams or 2 tons?
3 grams is lighter than 2 tons.
Why do most very large engines operate on two stroke cycle?
very large is the keyword here. for a very large engines that runs large machines, we need high power engines. two-strike cycle engines produce more power than 4-stroke cycle engines. that's why they are used. as they produce more pollution than 4-strokes, they must be limited to small spaced engines machines or large machines that required very high power.
