RedEyeFlightControl@lemmy.world 3 weeks agoDiesels that run CNG/Prop run it WITH the Diesel as an additive/power boost/starter aid. It is not a replacement fuel.
Propane/CNG injection is done through the intake manifold, not the injectors/fuel system. A diesel cannot and will not run solely on sparkable fuel.

Ah, I was not aware. I always did wonder how they did it on converted equipment, as the factory-built CNG buses here have something like a 13.6 compression ratio not 19ish like the diesels that get converted.
Kind of misleading then that the company doing the conversions doesn’t mention it.
