What is two advantages of a four stroke cycle engine over a two stroke cycle engine?
Pollution - 4 stroke has far less unburnt hydrocarbon in the exhaust.
Why fuel consumption is less in 4 stroke engine then in 2 stroke engine?
Why the fuel consumption is less in 4 stroke engine as compared to 2 stroke engine
Why you prefer four stroke engine over two stroke engine?
Four stroke engines are quieter than two strokes, but have less power.
Why do most very small engines operate on 2 stroke?
Most small engines are two stroke because you can get more power from a smaller engine with two stroke rather than a four stroke engine. It takes less to cool and to operate the engine.
Why does 4-stroke engine has higher RPM than 2-stroke engine?
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
Why does a four stroke engine run cooler than a 2 stroke engine?
A four-stroke engine runs cooler than a two-stroke engine primarily because it has a more efficient cooling system due to its longer cycle, which allows for more complete combustion and better heat dissipation. In a four-stroke engine, the intake, compression, power, and exhaust strokes are separated, giving more time for heat to escape during the exhaust stroke. In contrast, a two-stroke engine fires once every revolution, leading to less time for heat to dissipate and often resulting in higher operating temperatures. Additionally, two-stroke engines typically mix oil with fuel for lubrication, which can also contribute to increased heat generation.
Advantages of a 2 stroke?
-Low maintainence(no crank case oil to change or valves to set) -Simple in design (VERY easy to rebuild) -The ability to rev much higher than a 4-stroke(less minor shifting) -Impressive "snap" during the power band -Much less moving parts than a 4-stroke A 2-stroke engine fires on every complete engine cycle giving it, in theory, twice the power of a 4-stroke. Unfortunately, due to the engine design restrictions, the 2-stroke's power only becomes available at higher RPMs. At low RPMs 2-stroke engines are clunky and gutless. So, if you ride aggressive, your always on the throttle, you need that quick pick up often, you will benifit from it.
Give one advantage of a two-stoke gasoline engine over a four stroke cycle engine?
If you have a two stroke engine and a four stroke engine that are the same size, the two stroke will have almost twice as much power as the four stroke.Also, with a two stroke engine you never have to worry about changing the oil or making sure that there is oil in the engine.2t engines are more simple and generally have more boost than a 4t motor of the same size. They're very fun to work on if you're into that too.However, they're also a lot less reliable than a 4t, require frequent oil top ups, have lower economy and can seize if not calibrated correctly.But then again, the maintenance is part of the 2t fun.
Degree form of versatile?
More versatile Most versatile Less versatile Least versatile "versatiler" and "verstilest" are not words in the English language, you have to use the modifiers of more, most, less and least.
What is a 2 stroke dirt bike?
A 2-stroke engine requires that you mix oil with your gas where a 4-stroke engine uses gas straight out of the pump. A 2-stroke engine does not have any valves and therefore, weighs less than a 4-stroke engine. 2 strokes fire once for each revolution whereas a 4-stroke fires once every other revolution. 2 stroke engines are easier to maintain (less moving parts - no valves, no oil pump, etc.) However, you do have to mix your gas, they are less efficient and much worse for the environment, because there is constantly unburned oil and fuel passing through to the exhaust. yeh, basically a 2 stroke engine has one powerstroke in every 2 strokes of the piston. a power stroke is the piston stroke that provides the power, the spark plug fires and forces the piston downwards. so the 2 stroke cycle is basically compression, power, compression, power etc. it uses the start and end of these 2 strokes to also perfrom intake and exhaust. whereas a 4 stroke has one powerstroke for every 4 strokes of the piston. its cycle is intake, compression, power, exhaust. INTAKE - intake valve(s) open and as the piston moves down and suck in charge (mix of fuel and air), the intake valve(s) then close COMPRESSION- the piston moves upwards compressing the charge, at the top of this stroke the spark plug fires POWER- and ignites the charge forcing the piston downwards. EXHAUST- the exhaust valve opens and the piston moves upwards and forces the exhaust out.
Can you mix 2 cycle oil and ethenol?
Good question and also is more or less oil needed in the mixture for a 2 cycle engine?
Why two stroke engine not used in aircrafts?
In the two stroke petrol engine as you know suction,compression,ignition,expansion and exhaust is completed in only two stroke and one revolution of crank wheel more over diesel ignites at very high pressure which is not the same in case of petrol........if petrol is also ignited under pressure it explodes producing a big thumping sound.called KNOCKINGthis may reduce the power output and also lead to breakdown of the engine. For the above reason two stroke engine cannot compress air and ignite the fuel like diesel engine.
