What the piston in engine moves down due to combustion but how does it move up?

In the case of a single cylinder engine it would require a LARGE flywheel, so that rotary momentum is maintained. In the case of a multi-cylinder engine there are multiple firings of individual cylinders in 360 degrees of crankshaft rotation. Each cylinder as it fires helps the crankshaft maintain rotary momentum, thus a lighter flywheel is required.

In an internal combustion engine each up or down movement of a piston is called a what?
a revolution i believe, although that may be for the whole crankshaft not each piston a revolution i believe, although that may be for the whole crankshaft not each piston
The engine's changes up-and-down motion into rotary motion?
piston
Define the internal combustion engine?
Hi, this is from www.howstuffworks.com New HCCI Engine* More Auto Videos »= Internal Combustion = The ­principle behind any reciprocating internal combustion engine: If you put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible amount of energy is released in the form of expanding gas. You can use that energy to propel a potato 500 feet. In this case, the energy is translated into potato motion. You can also use it for more interesting purposes. For example, if you can create a cycle that allows you to set off explosions like this hundreds of times per minute, and if you can harness that energy in a useful way, what you have is the core of a car engine!Figure 1 Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. The four-stroke approach is also known as the Otto cycle, in honor of Nikolaus Otto, who invented it in 1867. The four strokes are illustrated in Figure 1. They are: * Intake stroke * Compression stroke * Combustion stroke * Exhaust stroke You can see in the figure that a device called a pistonreplaces the potato in the potato cannon. The piston is connected to the crankshaft by a connecting rod. As the crankshaft revolves, it has the effect of "resetting the cannon." Here's what happens as the engine goes through its cycle: # The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder-full of air and gasoline. This is the intake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work. (Part 1 of the figure) # Then the piston moves back up to compress this fuel/air mixture. Compression makes the explosion more powerful. (Part 2 of the figure) # When the piston reaches the top of its stroke, the spark plug emits a spark to ignite the gasoline. The gasoline charge in the cylinder explodes, driving the piston down. (Part 3 of the figure) # Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to go out the tailpipe. (Part 4 of the figure) Now the engine is ready for the next cycle, so it intakes another charge of air and gas. Notice that the motion that comes out of an internal combustion engine is rotational, while the motion produced by a potato cannon is linear(straight line). In an engine the linear motion of the pistons is converted into rotational motion by the crankshaft. The rotational motion is nice because we plan to turn (rotate) the car's wheels with it anyway.
What happens if you push down on a piston in a fluid?
the piston would push air down and fluid up.
Describe the energy transformation as the engines piston goes up and down?
When the piston goes up the heat temperature decreases while when the piston is down the heat temperature is increases.
What you mean by Stroke in internal-combustion?
A stroke in an internal combustion engine is when a piston moves up or down.
Within an internal combustion engine the can shape component that moves upand down the cylinder is the main moving part in the engine is?
Piston
Within an internal combustion engine the can shaped component that moves up and down the cylinder and is the main moving part in the engine is the?
Piston.
Within an internal combustion engine the can-shaped component that moves up and down the cylinder and is the main moving part in the engine is the?
it is called a piston
How fuel is processed in the engine in order to make the car operate?
A piston moves up and down inside the combustion chamber. In a four stroke engine when the piston is moving down it is drawing air and fuel into the combustion chamber. on its way back up it compresses the fuel then when it hits top dead center the spark plug sparks and causes an explosion which pushes the piston down, repeating the cycle.
What is meant by the term internal combustion engine?
An internal combustion engine is where the pistons open up, gas goes in them and then they close. The pressure causes an explosive reaction from the gas. That reaction moves the piston up and down. The piston is connected to the transmission and drive train. The transmission is connected to the wheels and when the piston moves the transmission moves and so on. When the piston opens up again, the old gas leaves through the exhaust pipe and new gas goes into the piston repeating the cycle over and over again.
Which stroke forces the piston downward in the four stoke process of an internal combustion engine?
The power stroke. The order is intake, compression, power and exaust. The piston moves down on intake and power but is only forced down on the power stroke
What is piston and its function?
piston is a plunger that moves ups and down in the engine block.the function of the piston is to compress air mixtures in the engine block
In an internal combustion engine each up or down movement by a piston is called what?
A stroke.
What happenes as the piston moves down?
when the piston moves down all of the water that is in the piston moves p and it comes out
What is the name of the part of an engine that moves up an down inside a cylinder?
Piston
How is a diesel engine different from other internal combustion engines?
Its a compression engine, as opposed to a spark driven combustion. No spark plugs! To start the engine, the piston is forced up (by a starter), it compresses the (heated) fuel in the piston which then ignites (under pressure) forcing the piston back down and initiating the engine to turn over.
