PREMIXED FUEL COLLISION DIFFUSION SYSTEM INTERNAL COMBUSTION ENGINE

PROBLEM TO BE SOLVED: To provide a combustion technology enabling constituting of a low environmental pollution diesel engine and a spark ignition engine friendly to a global environment and the human body, by radically improving the problem of a diesel engine and a substitute fuel engine by a new combustion system. SOLUTION: Fuel is premixed with air as a premixed fuel group in an auxiliary chamber 3, and generation of a soot dust is restrained by referring to a characteristic of a precombustion system and a vortex system to be supplied to a main combustion chamber. A volume part of the auxiliary chamber 3 is variably constituted by mobility of a sub-piston 4 as a means for strengthening a collision diffusion condition by increasing jetting collision energy of the premixed fuel group. That is, a new combustion system is developed for reducing a heat loss by enhancing an air utilization factor by strengthening the collision diffusion condition of the premixed fuel group. Thus, the occurrence cause of a carbonized particulate soot dust by high pressure spray diffusion combustion being a defect of a direct injection diesel is improved, and high heat efficiency is provided, and heat efficiency and exhaust low environmental pollution performance of a precombustion system, a vortex chamber combustion system and a spark ignition engine conventionally inferior to a direct injection system are improved.
