Title:
INSTALLATION STRUCTURE FOR FUEL INJECTION VALVE AND FUEL INJECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/119520
Kind Code:
A1
Abstract:
An end portion, on the combustion chamber side, of a fuel injection valve is projected
from a position of a wall surface forming an intake port, which position is superposed
on an imaginary plane that passes a wall surface from which an intake valve projects
and is normal to the center axis of a cylinder, or is projected from the imaginary
plane to the combustion chamber side. Alternatively, the center of an end portion,
on the fuel injection side, of a fuel injection valve for injecting fuel to intake
air flowing in a branch port branched from an intake port is placed closer to the
center axis side, in the radial direction of the cylinder, of a cylinder than to
the center axis of an intake valve. Alternatively, an upstream side fuel injection
valve injects fuel to intake air flowing at an intake port, and a down stream side
fuel injection valve injects fuel to intake air flowing at a branch port branched
from an intake port. Alternatively, the amount of injection of fuel is controlled
for each fuel injection valve for injecting fuel to intake air flowing at a branch
port branched from an intake port.
