Ken That is a huge question. That could not possibly be fully explained in this type of forum but let me see if I can cover some of the most basic ideas. Now days most if not all cars have an electronic fuel pump in the gas tank. When you turn on the key the fuel pump runs to pressurize the fuel system. Now when the engine is turned over if every thing is working properly the crank shaft is turned which moves the pistons up and down to keep this simple let us only look at one piston and what happens in each cycle. Car engines are called 4 cycle engines and this is why. Cycle one. Air and fuel are mixed in what is called the intake manifold. There is an intake valve that opens to let fuel in at just the Wright time. And when the piston is going down it is taking in the fuel air mixture. Hence intake. Cycle 2 the piston moves back up and the fuel air mixture becomes compressed. This is the compression cycle. Cycle 3 about this time a charge is sent to the spark plug and it ignites the fuel air mixture and forces the piston downward. This is the combustion cycle; this cycle is where the power is produced. And finally the fourth and last cycle is the exhaust cycle. After the fuel is burned it has to go somewhere so as the piston is going back up the exhaust valve opens and the piston pushes out the burned fuel and the exhaust valve then closes. And it starts all over again In cycle 2 and 3 the valves are closed There is a lot that goes on to make this all happen but, in a nutshell, that is it. These four things happen in the same order whether you are talking about a Portia 911 or that little 3.5 Briggs and Stratton engine on the lawn mower. Hope that all made some sence. Now for all you gear heads out there. I left out a huge amount of stuff I know, but I wanted to just paint the big picture. -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] Behalf Of Kenneth Suratt Sent: Saturday, June 09, 2007 10:38 AM To: [email protected] Subject: Re: [BlindHandyMan] flooring question I a interested in knowing how a car engine works. Starting from when the gas leaves the gas tank and finishes through the exhaust pipes. Could someone help me? ----- Original Message ----- From: Jennifer Jackson To: [email protected] <mailto:blindhandyman%40yahoogroups.com> Sent: Saturday, June 09, 2007 5:06 AM Subject: [BlindHandyMan] flooring question Hey Guys, I have been preauthorized for a home loan and have started the hunt. So if all goes well, I will be buying a house shortly. I am sure hoping you guys will have some help for me on a flooring question. I really like hard wood floors. Not just the look, but the sound and feel of walking on them. I think these are considered raised floors. How do I know what is under the carpet? I am looking at houses that were generally built in the 60's and 70's. I had always known I liked those kind of floors, but had not really thought about why until visiting the home of someone with a blind child who had built her house with those kind of floors because she had been told they will be helpful to him.
