Abstract

780,023. Fuel injection engines; cooling cylinders. PFLAUM, W. May 25, 1955 '[May 25, 1954], No. 15087/55. Classes 7(2) and 7(3) The temperature of the wall of an air cell or precombustion chamber 11, Fig. 1, in which the air is caused to rotate is automatically controlled by heating the wall,in dependence upon an engine operating condition such as speed, load, or engine temperature. In Fig. 1 the entry passage 16 to the cylindrical precombustion chamber 11 is provided with inclined guide vanes, shown developed in Fig. 5, which cause the entering air to rotate. The wall of the precombustion chamber 11 is surrounded by an electrical heating coil 17 embedded in an insulator 18 insulating the coil from the cylinder head cooling medium, which coil is controlled in accordance with engine speed, or output, or by a thermostat arranged in the engine cooling system. In modifications the coil 17 is replaced by or provided in addition to a coiled tube through which flows a fluid heating or cooling medium, permitting the chamber to be heated or cooled when desired. The fluid medium may be heated or cooled by chemical or mechanical means. In Fig. 2 the precombustion chamber is formed in a separate insert 9 which is arranged in a corresponding cavity in the cylinder head to leave a space 20 in which the heating coil 21 may be arranged or through which a heating or cooling medium may flow directly. The precombustion chamber may alternatively be heated by high-frequency electric heating means. The guide vanes, Fig. 5, for the air may be arranged uniformly or non-uniformly as shown. In Fig. 6, the combustion chamber is spherical and the injector is arranged on the axis 24 of the rotating air. If the engine has separate cylinder heads 31, Fig. 8, recesses 32 are provided in which the injectors 33 can be fitted without removing the cylinder heads; similarly, in engines having a common cylinder head for several cylinders, Fig. 9, the injectors are arranged in recesses 34 in the head in an inclined manner to permit removal. The heating means may be used to heat the precombustion chamber to facilitate starting.
