Abstract

625,779. Pumps ; regulating. NETTEL, F. April 1, 1947, No. 8836. Convention date, April 6, 1946. [Classes 7 (ii) and 7 (vi)] In a compression-ignition engine charged by an exhaust-actuated turbo-blower 19, 21, torque is increased at low speed and maintained constant under varying load, by burning fuel in a part of the charging air, which is branched-off from the main supply through a combustion chamber 15, and thus heated and then expanded in the turbine 21, Fig. 1, or in an additional turbo-blower 19b, 21b, Fig. 4. This heated mixture may flow through additional turbine nozzles or be mixed with the main exhaust before entry to the turbine 21 and the branched air may be pre-heated by an exhaust jacket. A valve 16, which controls the amount of air branched, may be controlled by hand or be under the dual control of a speed governor 40 and a capsule 50 subject to blower charging pressure. In addition to a manual valve 13b, the main engine fuel supply valve 13a, is also connected to this control by the linkage shown in Fig. 4 and a hand-control wheel 53 is also provided. The fuel flow to the combination chamber 15 is controlled by a thermostat 55 or a hand control 17. The additional turbo-blower is started by an electric motor 23 which drives through a free-wheel clutch 24. Coolers for the charging air are provided at 30, 31.
