Title:
GASOLINE FUEL SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/199348
Kind Code:
A1
Abstract:
A gasoline fuel supply system is provided with a feed pump unit (10), an inline pump unit (20), and a high-pressure pump unit (30). The feed pump unit, which has a non-positive-displacement electric pump (11), pumps up gasoline fuel from inside a fuel tank (7) and discharges the fuel at a feed pressure (Pf). The inline pump unit, which has a non-positive-displacement mechanical pump (21), pressurizes the gasoline fuel discharged from the feed pump unit and discharges the fuel at an intermediate pressure (Pm). The high-pressure pump unit, which has a positive-displacement mechanical pump (31), pressurizes the gasoline fuel discharged from the inline pump unit and discharges the fuel to a fuel injection valve (5) at a supply pressure (Ps).
