Diffenerence between 2 stroke and 4 stroke?
The difference is in the amount of stokes the piston makes in one cycle. A four stroke will explode on one stroke turning the engine over. Then on the up stroke it pushes the exhaust out. The next down stroke fills the cylinder with fuel. On the final stroke the piston compresses the fuel and the cycle repeats. This results in four strokes of the piston. A two stroke has two strokes of the piston before it repeats the cycle. The first stroke is the explosion. The piston is pushed down. on the down stroke the piston reveals a port that exhausts, and then another port is revealed that fills the cylinder with fuel. the up stroke compresses the fuel and then the cycle repeats. The logical difference is the 2 stroke will accelerate faster
The Compression Stroke pulls the fuel-air mixture into the cylinder?
No, the intake stroke pulls fuel-air into the cylinder, the compression stroke squeezes (compresses) this mixture into a small volume.
What are reeds used for on a 2 stroke motor?
The reeds in a 2 stroke engine perform the same task as intake valves in a 4 stroke engine. The reeds are mounted to a flat plate, or a cage, positioned behind the carburetor(s). On the intake / compression stroke, the reeds are pulled open, exposing the holes milled into the plate, or cage, allowing the fuel charge to be pulled into the engine crankcase from the carburetor. During the power, or exhaust stroke, as the piston moves down the cylinder, the reed valves are forced back against the plate / cage, preventing the fuel charge from being forced back out of the crankcase. This fuel charge is then forced around the crankshaft, (lubricating the rods and bearings), and into intake ports, which are milled into the side of the cylinder wall. As the piston travels back up the cylinder, the intake port is closed off, the exhaust from the previous stroke is expelled, and a fresh fuel charge is drawn into the crankcase via the reed valves. This cycle is repeated over and over, amazing these engines are so durable.
How many intake events are there in one revolution of a four cylinder engine?
There is only one intake stroke in a four-stroke engine. The other three strokes are compression, power, and exhaust. The intake stroke is a down stroke of the piston in which fuel is drawn into the cylinder while the fuel intake valve is open. The next stroke is the compression stroke in which the valves are closed and the fuel is compressed for combustion. The following stroke is the power stroke - a downward stroke of the piston after fuel combustion that drives the crankshaft. The final stroke is the exhaust stroke, an upward stroke of the piston as the exhaust valve opens to relieve the exhaust fuel fumes.
Fuel is combusted in the stroke of a four-stroke engine?
In the power stroke:Intake stroke --- draws the fuel mixture into the cylinderCompression stroke --- pressurizes the fuel mixturePower stroke --- ignites the fuel and causes the product gases to push against the pistonsExhaust stroke --- expels waste gases from the cylinder* PIE C is a good way to remember it. Or C PIE. *

How fuel works in cars engine?
All gasoline engines are four-stroke designs. An engine has an intake stroke where the intake valve is open and the piston is moving downward, creating a vacuum that sucks the fuel into the cylinder. The next stroke is the compression stroke. The intake valve closes, and the piston begins to move upward and compresses the fuel in preparation for ignition. The third stroke is the power stroke. The piston is approaches the top of the cylinder in the compression stroke. Just before it gets to top dead center, the spark plug fires and ignites the fuel. The fuel rapidly expands and pushes the piston down with great force. The last stroke is the exhaust stroke. In this stroke, the piston completes the power stroke and begins to rise again. At this point the exhaust valve opens, and the piston forces the exhaust out of the cylinder in preparation for the intake stroke.
Why ports are used in two stroke engines?
To deliver fuel and oil too the cylinder.
Can you name and describe the four strokes that make up one full cycle of a 4-stroke engine?
The Otto cycle, know as the four stroke cycle is as follows.InductionCompressionPowerExhaustThis is a simplified explanation of a petrol engine, the basic details are correct. Most are also relevant to a CI engine. It is not meant to be a definitive answer and is only a description for the basic operation.Induction:The inlet valve opens and the piston moves down the cylinder causing a partial vacuum and drawing an air/fuel mixture into the cylinder through the inlet manifold.Compression:The inlet valve closes and the piston moves up the cylinder compressing the air/fuel mixture. The compression ratios vary.Power:Near the top of the compression stroke a spark is induced and the air/fuel mixture is ignited. This causes the gasses to expand rapidly and forces the piston down the cylinder.Exhaust:The exhaust valve opens and the piston moves up the cylinder expelling the burnt gasses out through the exhaust manifold. The exhaust valve closes and the cycle starts again.intake: In this stroke air (and in non-fuel-injected engines gasoline) is drawn in.compression: In this stroke air (and in non-fuel-injected engines gasoline) is compressed (just before the end of this stroke in fuel-injected engines the gasoline is injected, then a spark ignites the fuel/air mixture).expansion: in this stroke the burning fuel/air mixture pushes against the piston, doing work.exhaust: in this stroke the burnt fuel/air mixture is pushed from the cylinder to make room for a fresh charge on the next intake stroke.Intake, compression, power, exhaust.The first stroke down takes the air/fuel mixture in thus intake, then as the cylinder rotates up, the mixture compresses. The fuel is ignited and the power stroke starts down and as the cylinder goes back up it is the exhaust phase where it expels the burnt fuel and then starts the first stroke again
How does gasoline get into 4 STROKE oil system?
Seepage of unburnt fuel through the piston cylinder.
What is two stroke?
A two stroke engine means that the piston makes two strokes to complete a firing cycle. Air and fuel is introduced into the cylinder through intake ports in the cylinder wall. Exhaust gasses are expelled through other ports in the cylinder wall. These ports are opened and closed by the piston moving up and down. When the spark fires the fuel it forces the piston down. On the way down the exhaust port is opened and exhaust gasses leave the cylinder. As the piston continues down it opens the intake port and allows fresh air and fuel in. On the way back up the piston closes off the ports and compresses the new air and fuel charge and the cycle starts over again. One down stroke and one up stroke = two strokes. For a better answer see commercial website howstuffworks, they also have an animation which clarifies beyond doubt what it is and how the two stroke technology is different from a four stroke technology
During an engines intake stage what passages inside the cylinder head must the incoming air and fuel mixture flow though in order to enter the cylinder?
Intake valve must be open to allow atomized fuel mixture to enter cylinder--than all valves are closed during compression stroke 4- stroke engine 1) intake valve open to allow fuel mixture to enter cylinder 2) compression stroke all valves closed 3) ignition stroke mixture is ignited by spark from spark plugs 4) exhaust stroke--exhaust valve is open to allow residue to escape
