Propane injection to the extreme?
Check this out. Uses Diesel to light the CNG/LNG, could probably be set up for propane. Anybody with a propane system know how much propane you run compared to how much CNG/LNG this thing can stand?

Re:Propane injection to the extreme?
What it saying is that it uses Diesel/CNG-LNG to take off then when coasting on the highway it uses CNG-LNG. Bascily like add a 200 shot of LP to your truck and taking some of the Diesel away. Its like 50/50. The thing is that CNG-LNG is heck of alot cleaner and doesnt blow smoke. I know the PSD's can handle aleast a 200 shot of LP. I wonder if our trucks can run CNG-LNG?

Although I think the Cummins engines have spark plugs...

You mean glow plugs?

Westport Innovations Inc., through its joint venture Cummins Westport Inc. (CWI), has a wide range of low-emissions, high performance natural gas powered engines for many applications. We have contributed our Westport-Cycle™ technology and other proprietary natural gas technologies, and Cummins has contributed its current on-highway vehicle medium-duty spark-ignited natural gas engine businesses and proprietary engine-related technologies for on-highway vehicles, industrial and power generation applications. Cummins manufactures the engines for CWI and those engines are exclusively distributed and serviced by the Cummins global distribution system.<br><br>More detailed information on the entire CWI product line is available at the Cummins Westport website at: http://www.cumminswestport.com.<br><br><br><br>no... I mean SPARK plugs... at a 10:1 compression ratio and a full natural gas or propane engine how else do you make it ignite??

No Diesel/Propane/LNG injected motors have spark plugs its either heating grid (CTD) or Glowplugs (Ford&Chevy). Its all done by Compressed ignition. Even if it has a lower compression ratio than normal.

Re:Propane injection to the extreme?
Anybody have a clue how little compression it takes to keep our engines running? Can 10.5:1 still ignite diesel?<br> Tony

Re:Propane injection to the extreme?
It will all depend on the intake air temp and the fuel atomization. For diesel fuel to ignite it takes a minimuim of 450 degrees Farenheit. If you didn't run an intercooler and coudl really get a super fine spray from the injectors, then it "MIGHT" be enough, but only after the engine got warm.

Re:Propane injection to the extreme?
If you read these articles by Bruce Mallinson, on big Cummins motors he drops the compression down to 14:1, cranks up the boost and fuel and retards the timing. He's going for million-mile longevity in class 8 trucks while making 2500 ft/lbs of torque, so his goals are a bit different than ours.
