diesel compression ratios
 

does anyone have a chart that has compression ritios for various brand diesel engines?

afterthought; a chart would be ideal but rare, it would be great if everyone could give the type and size of thier diesel engines as well as the compression ratios and i will make my own chart, thankyou

6.0l (03-04) = 18.5:1

i seem to remember the 88 7.3 was around 22.5 to 1

The Powerstroke from 99-03 is 17.5:1

good start folks, any vehicle, any year, any diesel.

94-97 PSD is also 17.5:1

That pretty much makes this a "general diesel" thread.....
Moved to proper forum

thankyou, keep them comeing folks.

pre power stroke 6.9 = 22.5 7.3 = 21

I have been reading,

Calvin

6.0 Perkins Phasser 17.5
4.0Perkins Phasser 17.5
1004 Perkins no turbo 16.5
1006 Perkins " " 16.5
1004-4T " Turbo 16.1
1006-6T " Turbo 16.1
5.9 Cummins Turbo 17.6 innercooler
5.9 " N/a 18.5
5.9 " Indust,Turbo 16.5
GM 5.7 n/a 22.5
GM 6.2 n/a 21.5
ford 6.9L n/a 20.7


Hope this helps ran out of time will keep looking though my books latter

thats great, the reason i need these is cause i am doing a diesel project and need to know the compression ratios to choose what engine to use, i need the highest ratio possible. thanks!

What kind of project I am sure we would all gladly build it for you and let you have the credit. :-X07



an old 5.7 chev or 6.9 diesel would proly be your best bet for highest compression.

well,,,aaa,,, i'll tell you guys more a little later, when i figure out if it is possible.
someone told me that some old dozers (humm, i hav'nt used that z botten in a while) oh sorry was i thinking out loud again, any way someone told me that some old dozers do not have glow plugs and their compression ratios were alot higher than normal, is that true?

well most old tractors don't use GP's, as far I know the old 460 and 560 farmalls where the only ones that use them from IH, all the other I-6's didn't. Let me dig up an old book I have and see if it has CR for anything realy old.

None of the Perkins use GP,s are Cummins, the DT466 didn,t have them eather.

I dunno about that, I've got a Farmall 706 diesel that has GPs, and I'm pretty sure it's a Perkins I-6. I could be wrong though.

Dam good motor too!
