Title:
FUEL INJECTION DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2014/115511
Kind Code:
A1
Abstract:
An engine (10) has gas injection valves (21) as fuel injection parts, and fuel conduits (22) are connected to the tips of the gas injection valves (21). The fuel conduits (22) have first ends connected to the gas injection valves (21) and second ends connected to first branched tubes (13a), and gas fuel injected from the gas injection valves (21) is discharged to the first branched tubes (13a) via the fuel conduits (22). The fuel conduits (22) are provided with inflow regulation parts for regulating the flow of air into the fuel conduits (22) from an air intake side by locally reducing the passage surface area in the fuel conduits (22) or by closing the passages.
