Title:
内燃機関の燃料供給装置
Document Type and Number:
Japanese Patent JP4462286
Kind Code:
B2
Abstract:
A fuel supply device has two fuel injection systems having delivery pipes (12A, 12B) and fuel injection valves (16), and also has a pulsation damper (20). The fuel injection valves (16) are intermittently opened while fuel is sent under pressure to the two fuel injection systems through a common fuel pump, and this causes the fuel in the delivery pipes (12A, 12B) to be supplied from the fuel injection valves (16). Paths through which the fuel passes include a first path having the delivery pipe (12A) and a communication path (13) and also include a second path having a branch path (17) and the delivery pipe (12B). A facing portion (P) to which an opening of a path (21) faces in the delivery pipe (12A) includes an opening, in the delivery pipe (12A), of the branch path (17). Pulsation of fuel pressure occurring in the two delivery pipes (12A, 12B) can be accurately suppressed by the single pulsation damper (20).
