Title:
FUEL INJECTION DEVICE AND FUEL INJECTION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019138249
Kind Code:
A
Abstract:
To provide a fuel injection device capable of quickly preparing an air-fuel mixture suitable for ignition while suppressing degradation of combustion properties of an internal combustion engine and increase of equipment costs, and an injection control device for controlling the fuel injection device.SOLUTION: A fuel injection device (30) is provided to inject a high-pressure fuel in an accumulator vessel (32) into a combustion chamber (38) of an internal combustion engine (10) including an intake port (12B), and an exhaust port (23B) disposed in opposition to the intake port. The fuel injection device includes a tip end portion (53) inserted into the combustion chamber between the intake port and the exhaust port of a top face (38A) of the combustion chamber. The tip end portion includes high penetration injection holes (61, 64) for injecting the fuel in a direction from the tip end portion toward a part between the intake port and the exhaust port in the combustion chamber, and low penetration injection holes (62, 65, 67) for injecting the fuel in a direction from the tip end portion toward the intake port or the exhaust port in the combustion chamber with penetration force lower than the fuel injected from the high penetration injection holes.SELECTED DRAWING: Figure 3
