In bigger difference, some areas based on CNG combustion gas resource, have based on LNG combustion gas resource, this has resulted in gas only
The inconvenience of system passenger vehicle inflation.
And the gas componant that CNG and LNG gas burning system adopts is methane, the mode that simply stores is different, CNG be by
Methane is forced into 20Mpa at normal temperatures and is stored in CNG gas cylinder, and LNG is to be stored in being cooled to -162 DEG C under methane normal pressure
In LNG gas cylinder.Because the gas componant that both adopt is identical, thus providing two sets of gas burning systems can share same electromotor
Condition.
