Title:
CYLINDER-INJECTION-OF-FUEL-TYPE SPARK IGNITION INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3573138
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cylinder-injection-of-fuel-type spark ignition internal combustion engine capable of surely enlarging a stratiform combustion area to a high load side by securing the ignitionability.
SOLUTION: This cylinder-injection-of-fuel-type spark ignition internal combustion engine is provided with a fuel injection valve for injecting comparatively thin approximately fan-shaped fuel to make the fuel collide with a bottom wall of a cavity on a top of piston at an acute angle, the bottom wall of the cavity is provided with plural fuel guide passages adjacent to each other to guide plural collided fuel parts to a sidewall of the cavity under the consideration of radially dividing the injection fuel into plural fuel parts, the sidewall of the cavity is provided with a first fuel deflection passage and a second fuel deflection passage for deflecting two of plural fuel parts guided by plural fuel guide passages to pass through the neighborhood of an ignition plug, and a collision angle TH1 of the fuel in the first fuel guide passage 81a for guiding the fuel part to the first fuel deflection passage is smaller than a collision angle TH2 of the fuel in the second fuel guide passage 81b for guiding the fuel part to the second fuel deflection passage.
