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.


If the temperature is kept constant and the piston moves down to decrease the volume the pressure increases because the gas particles?

The pressure increase because pV=k.


How does burning gasoline make a car move?

There are four steps to the cycle of a car's engine. These steps involve the combustion, or burning, of gasoline as a force that drives the procedure, and therefore moves the car. (1) Intake: The cyllinder of the engine has a piston that can move up and down, much like pushing a cotton ball up a straw. The intake stage occurs when the piston moves down the shaft. The vacuum created by the falling piston pulls gas and air into the space. (2) Compression: As more of the air/gas mixture enters the shaft of the piston, pressure increases. (3) Power/ Ignition: Eventually, the pressure reaches a critical point where the gas/ air mixture ignites, forcing the piston up and moving the car. (4) Exhaust: After the explosion, the exhaust (smoke) is released from the piston as it moves back to the rest position and begins to take in more gas and air.


Why does cars need gas?

the gas ignites on the spark plug that moves the piston witch runs the motor and that runs the wheels


Why would a gas not be suitable to fill the tube that moves the piston in the rubbish - mover?

Gas is likely to be too easy to compress.


How does a car engine use gasoline for power?

cars get power from gasoline because when the gas enters the cylinder the spark plug explodes the gas which pushes the piston down and turns the crank shaft which moves the car


What happens to a particle in a gas when heated?

It moves Faster.


How do cars use gas?

Simple explanation : the gas in forced into the cylinder, then the piston compresses it, then the spark plug makes it explode, which forces the piston back down, turning the crankshaft, forcing another piston into compressing more gas. rinse and repeat.


If a sealed syringe is plunged into cold water in which direction will the syringe piston slide?

Think about what happens to the gas (air) inside the syringe when the temperature decreases. As the gas cools it will occupy a smaller volume and thus the syringe plunger will move DOWN the barrel.


What is a piston?

A piston is essentially a moving "stopper" in a cylinder. It fits closely and responds to mechanical pressure from a connecting rod on one end or from a fluid on the other end. In air compressors that have pistons, the crankshaft turns and moves the piston (which is linked to the crank via a connecting rod) up and down in the cylinder to compress gas (like air). In an internal combustion engine, a burning fuel-air mixtue expands and forces the piston down, which transfers mechanical energy to the crankshaft. Use the link to the related question about what a piston does for more information.

How does gas get in crankcase of 2002 Dakota?

It runs down past the piston rings. It may be a misfire or leaking injector.It runs down past the piston rings. It may be a misfire or leaking injector.
