Abstract

698,600. Fuel injection pumps. CATERPILLAR TRACTOR CO. March 24, 1952 [Jan. 21, 1952], No. 7495/52. Class 102 (i). In a fuel-injection pump in which the head of the piston 20 controls the inlet port 15 to initiate injection and the relief edge 31 controls the end of injection, a portion of the head is relieved at 40 so that when the engine is running, at a slow speed under overload, the initial part of the injection is made at a reduced rate and the beginning of injection is retarded.
