The option of using an aero- Diesel engine to be able to run from Jet-A1, which is plentiful at many airports seems to be a good approach, and far preferable to having a heavy, bulky pressure vessel onboard.
Do you have a reference for lower NOx emissions from propane? My understanding is that most NOx is a product of combustion in air (although it can come from impurities in the fuel).
As for SOx, natural gas can contain H2S which produces these, is it normally significantly less for propane?
- Gordonjcp 4y agoThere's no H2S in propane, although there's a little methyl mercaptan in it as an odourant so it "smells of gas". As for the NOx emissions I'm not sure why it's lower as in theory it should burn hotter - LPG runs lean which is why there's no CO, but that should make more NOx.
