Abstract
Methods and systems are provided for a gear driven diesel fuel injection pump of an engine. In one example, a front end of an engine includes an idler gear in meshing engagement with a first end of a crankshaft and a fuel pump drive gear in meshing engagement with the idler gear. The front end of the engine may further include a fuel pump, where an input shaft of the fuel pump is directly coupled to the fuel pump drive gear.
Claims17
A front end of an engine, comprising:
- a first end of a crankshaft;
- camshaft pulleys;
- an idler gear in meshing engagement with the first end of the crankshaft, the idler gear positioned below the camshaft pulleys, a belt coupling the camshaft pulleys and the idler gear;
- a fuel pump drive gear in meshing engagement with the idler gear;
- and
- a fuel pump, an input shaft of the fuel pump coupled to the fuel pump drive gear, wherein the fuel pump is a single plunger pump and a piston of the fuel pump moves twice per turn of the fuel pump drive gear.
3 more elements
A method for an engine, comprising:
- driving rotation of an idler gear via a first end of a crankshaft in meshing engagement with the idler gear, the idler gear arranged at a front end of the engine;
- driving rotation of a fuel pump drive gear via the idler gear, the idler gear in meshing engagement with the fuel pump drive gear;
- driving rotation of an input shaft of a fuel pump via rotation of the fuel pump drive gear;
- and
- moving a piston of the fuel pump twice per full rotation of the fuel pump drive gear and the input shaft.
2 more elements
A system for an engine, comprising:
- a front end, comprising:
- a first end of a crankshaft;
- an idler gear in meshing engagement with the first end of the crankshaft;
- a fuel pump drive gear in meshing engagement with the idler gear, the fuel pump drive gear having a same number of teeth as the first end of the crankshaft;
- and
- a fuel pump, where an input shaft of the fuel pump is directly coupled to the fuel pump drive gear;
- and
- a back end, arranged opposite the front end, the back end including a flywheel coupled to a second end of the crankshaft,
- wherein the front end further comprises an oil pump drive gear in meshing engagement with a crankshaft pulley directly coupled to the first end of the crankshaft and directly coupled to an input shaft of an oil pump, wherein an oil pump belt contacts each of the crankshaft pulley and the oil pump drive gear.
