RE: [BlindHandyMan] How a car engine works.
Robert my man... You only missed one small detail. Otherwise your answer was spot on. Intake you had correct The compression stroke is where the air-fuel charge is compressed and the ignition system fires the charge. The third stroke is called the power stroke. This is where the valves remain closed and the compression explosion forces the individual piston down so that it can do its share of the work rotating the crank. Stay tuned next week for uncle bob's engine room. Good job Guy. Regards Larry Stansifer Keep your friends close and your enemies closer.

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: blindhandyman@yahoogroups.com [mailto:[EMAIL PROTECTED] Behalf Of Kenneth Suratt Sent: Saturday, June 09, 2007 10:38 AM To: blindhandyman@yahoogroups.com Subject: Re: [BlindHandyMan] flooring question I a interested in knowing how a car engine works.
