Abstract
Description
technical field
[0001] The present invention relates to a storage device for liquefied gas fuel which stores liquefied gas fuel used as vehicle fuel and pressurizes the liquefied gas fuel to an engine. Background technique
[0002] As exhaust regulations have been strengthened in recent years, vehicles using LPG (Liquefied Petroleum Gas) or DME (Dimethyl Ether) as fuel for the purpose of reducing pollution tend to increase. In particular, DME is valued because of its high cetane number and extremely low emission of PM and NOx.
[0003] As a device using DME as fuel in this way, for example, as in Patent Document 1, a configuration has been proposed in which, among the DME fuel pressure-fed from the fuel tank to the engine, once the fuel remaining when the engine is stopped is sent to the purge tank Returned and depressurized, then sent to the fuel tank. This is because the DME fuel is pressure-fed from the fuel tank to the engine at high pressure, so it is depressurized in...
