PURPOSE:To improve a mixing condition of injected fuel and air by setting an injection axial center of a fuel injection nozzle in a direction crossing a gas expulsive means in a vortex chamber, striking the injected fuel against the gas expulsive means for scattering, and thereby obtaining further fine and diffused injected fuel. CONSTITUTION:An injection port 2 is tangentially communicated with a vortex chamber 1 of a Diesel engine, while a main combustion chamber 3 is communicated with the vortex chamber 1 through the injection port 2. A fuel injection nozzle 4 is faced to the vortex chamber 1, while a gas expulsive means 5 is arranged on a center of the vortex chamber 1. In the above-mentioned vortex chamber type combustion chamber, an injection axial center 6 of the fuel injection nozzle 4 is set in a direction crossing with the gas expulsive means 5. The fuel injected from the fuel injection nozzle 4 is struck against a fuel striking surface part 9 on an outer peripheral surface of the gas expulsive means and in the vicinity of an intersection 8 with the injection axial center 6, and scattered.
