Thought I would follow up on my other thread from 2009 on my propane injection. http://www.dieselplace.com/forum/showthread.php?t=315409
My burb now has 195K miles on it, roughly 40K with propane. The propane kicks in on early while increasing speed and stays on above 45mph. Injection is about 2/3 GPH or 60Kbtu/hr. It still gets about 18MPG city.
Recent addition - 1999 Mercedes e300 it Likes propane :)
2nd addition - 26' travel trailer - 5500 dry lbs.
Over Memorial day I towed the TT almost 3K miles from South Florida to San Antonio Tx. I can feel/hear the truck work when I exceed 45 MPH with the trailer.
Rough numbers for comparison on mostly flat ground.
MPH / MPG / Turbo / Engine / EGT
55 / 14 / 0 PSI / 180 / 600
60 / 12 / 1 PSI / 190 / 700 / == 2K RPM
65 / 10 / 5 PSI / 200+ / 800
Pulling the hills on cruse @65 MPH I lost up to 5 MPH, droped out of OD,the TC jump to 8 PSI and the EGT run to 1100. Most of the trip I stayed at 55 for all for the reasons stated above.
After the 3K miles there is no diesel smoke evident on my TT. I am almost thinking it is burning too clean for a diesel.
I am curious if others are seeing the similar results. Should I turn up the turbo a little and/or add a higher shot of propane pulling the hills?
