PROBLEM TO BE SOLVED: To develop an energy-saving/low pollution internal combustion engine enabling use of a variety of fuels by solving breakage of a piston jet penetration portion caused by jet overlapping by ultra-high pressure and multi-jet hole nozzle, and excessive jet penetration characteristic by ultra-high pressure, and a generation factor of carbonized soot dust.SOLUTION: A flow form of air flowing into a cylinder is strengthened, and a swirl flow eliminates end region knocking to achieve a target of high compression ratio of an internal combustion engine. A factor of carbonized soot dust by excessive jet flow by ultra-high pressure hole nozzle is eliminated by combustion with mixture of a group of lean injection fuels of injection fuel by a large-diameter throttle nozzle with an intermediate pressure and air, and means for stabilizing conditions of complete combustion is composed of a spark ignition method, thus lean fuel injection nozzle technology for complete combustion technology of the internal combustion engine which enables use of a variety of fuels by combustion of high compression ratio of the internal combustion engine, and makes PM soot dust of exhaust harmless by being incinerated by combustion, can be provided.SELECTED DRAWING: Figure 2 |
