Diesel / CNG discuss

That's why I wrote a specific CNG tune, with less diesel fuel, and more boost.

LMAO I was wondering where Charger and his 12 year old style of reasoning disappeared to.

LMAO too he still cant tell the difference between CNG and Propane :banghead:

read the thread guys, i gave you how to find it on here, this has been well covered, if cng or propane are being introduced into the engine with the air, it is an untimed fuel, the exact opposite how your diesel engine is built to function. If you want your exspensive high compression diesel engine constantly pre-igniting that's you and your engines thing, ass kissers LOL

Wow...This is alot of mis-information.

Diesel is a relatively high cetane fuel (low resistance to "knock" or ignition by compression). CNG is a high octane fuel (high resistance to ignition by compression). The CNG needs something to ignite it. In a dedicated NG engine, it's usually done with a spark plug. In a dual fuel engine, high percentages of CNG are ignited with a diesel micro-pilot. The diesel injection is of course timed.
