How does cars run on gas?

Question

any kinds of cars

Answer 1

Very simple answer:
When burned, gas releases energy. This energy makes your car go.

Simple answer:
Gas combined with air is put under pressure and ignited. When it burns it makes roundee round things go round and round. Things going round and round make your car go.

Not so simple answer:
A stream of air enters your car's engine past a device which measured its flow rate, temperature and other data. This and other information is fed into your car's computer which then meters the proper amount of gas to inject into the air stream directed at the back of the intake valves. When the intake valves open, the fuel/air mixture enters the combustion chamber where a piston pressurizes it before a spark ignites it, causing an explosion which pushes the piston downward. The downward motion of the piston creates circular mechanical motion which is then routed through a transmission to the wheels of your car creating forward (or backward) motion.

Answer 2

If you can imagine a few strong lazy darwfs living under the hood of the car. They can turn a crank to make the car move, but they're really lazy. When you step on the accellerator, a bit of gas and oxygen is mixed and fired off to gave a spark. This spark burns the little darwfs to work harder. In most cars ,these drawfs are call pistons, but in the past, there were rotary engines which had one big fat lazy darwf that ran on a round wheel like a hamster instead of cranking shafts up and down.

Answer 3

The engine sucks in gas mixed with air. the mixture is then compressed by the cylinder and the spark plug starts a burn (not an explosion) the burn expands the compressed mixture and pushes the piston which is where the power is generated. The burned gas/air mixture (exhaust) is then pushed out of the engine and the process is started again. This process happens in two revolutions of the motor, so this may be occuring as much as 3000 times per minute at 6K rpm.

Answer 4

Petrol and air are mixed by the carb then injected into the cylinder via the inlet valve. As the piston rises the mixture is compressed then there is a spark and the mixture is ignited forcing th piston down on its power stroke the the burnt mixture exits the cylinder via the exhaust valve. There are various types of engine but they all work on the same principle. Diesel for instance doesn't use a spark the mixture is ignited by high pressure injection into the cylinder.

Answer 5

Gasoline explodes because of pressure and spark from spark plug. Expanding gas from explosion pushes piston down which turns crank shaft the turns fly wheel that turns transmission gears that turn drive shaft that turns rear end gears that drive the wheels that make the car go :)

Answer 6

Not NEARLY as well as they run on diesel fuel. That's why my VW Jetta station wagon AVERAGES 48 MPG and why over half the cars in Europe are diesels. Hybrids, pie-in-the-sky-brids . . . diesel engines are the way to go!

Answer 7

thats a great question


dont no
its one of those things you take for granted
