| 摘要 | PURPOSE:To reduce the vibration of combustion and improve combustion efficiency as well as the stability of combustion by a method wherein the title device is constituted of an injection piston, injecting fuel, and an injection piston rotating means, equipped on the injection piston and providing the same with a rotary motion. CONSTITUTION:Fuel, leaked from an injection hole 1 into a combustion chamber 6c, is ignited by an ignition plug 9. After the ignition, an injection piston 1 is pushed rearward by a combustion pressure generated in the combustion chamber 6c whereby the fuel in a fuel chamber 6d is compressed. The fuel is injected into the combustion chamber 6c through the injection port 1d of the opening 1a of a piston 1 by the compression and is bursted while a missile 8 is flown by the gas of the bursting through a bore 7a. In this case, a rotation driving unit 1c, engaged through a steel ball 4, is turned by the spiral grove 3b of a rotation guide 3, fitted into and fixed to the second inner tube unit 6b of a breech ring 6 when the piston is retreated. As a result, the opening 1a is rotated and, therefore, the injected fuel becomes rotating jet stream and is diffused widely into the combustion chamber 6c whereby the fuel is bursted. | ||||||
