Internal combustion engine
This patent describes an improved internal combustion engine of the diesel type, including a cylinder block having a cylinder bore therein, a head connected to the block covering one end of the bore, exhaust and air intake ports connected with the bore, a piston located in the cylinder bore and movable toward and away from the head, starter means for reciprocating the piston, and fuel supply means for injecting fuel into the cylinder bore. The improvement comprises: an ignition plug member connected to the head; a precombustion chamber defined by the piston and the plug member, the precombustion chamber connected to the fuel supply means for injection of fuel thereinto; and a main combustion chamber in the cylinder bore defined by the piston, head and block, the main combustion chamber connected to the precombustion chamber when the piston is remote from the plug member and isolated therefrom when the piston is located proximate the head.
