ABSTRACT:
For starting a compression-ignition internal combustion engine, a solenoid valve is electrically energized simultaneously with the starter motor (the valve remaining electrically energized while the engine afterwards continues to run) to supply oil pressure from the engine oil pump to a first piston-in-cylinder device to move a fuel injection pump lever from "stop" to "run" against a first return spring, so that fuel supply always (even when starting) depends upon adequate oil pressure. A second piston-in-cylinder device with a second return spring is responsive after a delay to the oil pressure to change the engine from at least partial decompression to full compression.
