RECIPROCATING INTERNAL-COMBUSTION ENGINE, IN PARTICULAR DIESEL-ENGINE

摘要

A reciprocable piston internal combustion engine, especially diesel engine, with an air guiding passage leading to a combustion chamber for combustion air to be conveyed by the air feeding passage. The air feeding passage is provided with twist-forming elements. Also means are provided for controlling air injection and are actuated dependent upon load or smoke with the opening cross section of the air feeding passage being variable within predetermined limits. The oxygen supply is kept low during the combustion of the air with the fuel in the center of the combustion chamber during all load ranges of the internal combustion engine. Combustion air which is rich in oxygen and stays close to the wall of the combustion chamber is affected by the radially progressing combustion only when the temperature in the combustion chamber or cylinder starts dropping in view of the expansion of the air-fuel mixture.
