Title: Cylindar pressure Post by: Lost on November 01, 2014, 04:12:19 AM (http://i1360.photobucket.com/albums/r658/Lion_32/graf_zps7cdd322e.png~original)
This graph tells me that the greatest load on the Engine is at 4700 rpm. It is at about 200 load and 25 deg timing. This would mean that cyl pressure at 3500 rpm (190 load, 22 deg timing) is lighter on the Engine which we can see in TQ graph as well. Boost is the same at 24 psi from 3500 rpm to 5000 rpm as is fueling 12 afr. My question is. Am i right in my conclusions?

Btw you dont have to use screen shot for graphs... use file->export Title: Re: Cylindar pressure Post by: phila_dot on November 01, 2014, 10:36:59 PM Not really.
What do you mean by cylinder pressure? If you are referring to the compression stroke, then yes, but if you are referring to the expansion stroke then no, you can't infer that from load. It isn't load on the engine, load is cylinder filling or air charge, which is only potential. |
