Engines are pretty simple Nancy. Its all the stuff that's added onto them which makes them so complicated. Here you go.

You know what a cylinder is right. Think of a flashlight with the bottom and light removed. Take one battery out. The battery left is the piston. You can make the piston go up and down by putting your hands over each end and tilting the light one way then the other. Just like the piston in the cylinder of an engine. Now imagine you put some gas in the bottom of the flashlight.(just a few drops) Drill a Little hole in the bottom end and screw it back on. With the battery still inside touch a match to the hole. The exploding gas will push the battery down right. (theoretically). Same as in an Engine. Fuel is ignited on one end of the cylinder and explodes pushing the piston down. The linear force of the moving piston is transmitted to a shaft via a (connection) rod connected to the piston. The Shaft (crankshaft) turns the linear force into a rotational force. The rotational force passes through the transmission, driveshaft and turns your tire. If you add 3 more pistons all connected in the same way to the crankshaft, in seperate cylinders. You now have a 4-cylinder engine and the power to the tires has been increased 4 times. Use what I said in conjuction to the diagrams etc given in the "the how things work" website. Finally you will have to learn the 4 things which describe the piston's movement in the cylinder. Yes, it only goes up and down. But it does 1 of 4 things when it does. 1st thing- piston goes down and sucks in the fuel through a valve located at the top of the cylinder. This is called the Intake Stroke. Then the piston goes back up and the valve closes so the fuel can't get out. This is called the Compression Stroke (the fuel is compressed at the cylinder top). Now via a Spark Plug screwed into the top of the cylinder the fuel is Ignited (Boom, causing the piston to be pushed down and also why we have the Muffler). This is called the Ignition Stroke. This is the linear force which after being changed into a rotational force turns your tires (remember). Finally the last stroke which is called the Exhaust Stroke. The piston goes back up and pushes the burned gas out another valve which opens at the top of the cylinder (then out the muffler pipe). Thats it, then the whole thing repeats all over again. While one piston is in its Intake Stroke. Another is in its Exhaust Stroke and the 3rd Piston is in its Compression stroke, 4th in the Ignition Stroke (also called the Power Stroke). But don't get too involved in gasoline engines. Because of the high cost of oil and its pollution. We are all going to be driving Electric Cars in 10 years. Except for the Ethanol burners which will still have engines. See Tesla, Phoenix and there are several others. The Hybrids started it, next will come PHEVS (like the GM Volt), then full Battery Operated cars, then maybe Fuel Cells. Hope I helped. (Nano-Technology is making the battery possible. See A123 Systems and Altair, there are others.)

Answer 3

great website for you and all that want to check it out, how stuffworks.com. you would be surprised what you can find in there. everything from simple engines on to chemicle warefare and nuclear weapons. i have enjoyed just going and looking around.
