20090139493 | Synchronizing common rail pumping events with engine operation - Noise and vibrations associated with a common rail fuel system drive linkage are reduced by synchronizing a high pressure common rail supply pump with engine operation. This may be accomplished by selecting a linkage associated with a desired ratio of engine speed to pump speed along with selecting a number of pump plungers and cam lobes that results in synchronizing action of the pump with engine combustion events. In particular, a pattern of pumping events per engine cycle repeats during each engine cycle. In a more sophisticated version, the pattern of pumping events per engine cycle includes a sub-pattern of pumping events that repeats an integer number of times each engine cycle, where the integer number equals the number of engine cylinders. | 06-04-2009 |
20090272366 | Internal combustion engine set up method and fuel pump having installation assist mechanism - A method of setting up a common rail internal combustion engine system includes setting a fuel pump for a common rail of the engine system at a configuration where a camshaft of the fuel pump is rotationally stable.
