Title:
CYLINDER INJECTION TYPE SPARK IGNITION INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2008038814
Kind Code:
A
Abstract:
To provide a cylinder injection type spark ignition internal combustion engine capable of excellently strengthening a tumble flow by injection fuel.
This cylinder injection type spark ignition internal combustion engine strengthens the tumble flow by the fuel F injected toward a cylinder bore in the vicinity of an intake bottom dead center in homogeneous combustion. Fuel injection pressure is reduced when the measured or estimated temperature of the injection fuel exceeds a preset upper limit value, and the fuel injection pressure is further reduced as the measured or estimated temperature becomes high.
