Effects of Charging and Compression Ratio on Net Work |
|
|
|
* The inclosed area in the pV diagram represents the net work of the gases. |
|
Normal and Abnormal Combustions |
|
|
|
* Normal combustions are in dotted lines and abnormal combustions in solid lines on the pV diagrams. Decrease in area means less net work from the gasses. |
