The Internal Combustion Engine
    
     This site gives an overview of all the techniques used to study combustion processes and a guide to aid the understanding of the combustion cycle as a whole.

                  The internal combustion engine converts chemical energy into useful mechanical energy by burning fuel. Chemical energy is released when the fuel-air mixture is ignited by the spark in the combustion chamber. The gas produced in this reaction rapidly expands forcing the piston down the cylinder on the power stroke. The basic components for a combustion cycle in a four stroke engine are the combustion chamber (cylinder), piston, intake port and outlet or exhaust port. The piston reciprocates inside the cylinder, exhaust and intake ports open and close during various stages of the cycle. The movement of the piston up or down the cylinder makes up one stroke of the four stroke cycle (Otto cycle). The linear motion is then converted to rotary motion by the crankshaft. The crankshaft is shaped to balance the pistons which are fired in a particular order to reduce engine vibration (typically for a 4-cylinder engine, 1-2-4-3 or 1-3-4-2). The flywheel then helps smooth out the linear movement of the pistons.


              I hope you enjoy visiting my engine pages as much as I have enjoyed creating them. Use the  links ( two/ four stroke) on the top to start gaining.
 
             As always, I would love to hear your comments about this site. Are there any other engines you'd like to see? Let me know! (I already have to-do list) Also, please contact me if you feel I have made any errors or omissions.
