Abstract

The present disclosure proposes a camshaft (103) for an internal combustion engine (101). The camshaft (103) for an internal combustion engine (101), comprises at least one cam (102) machined 5 on the camshaft (103). The camshaft (103) is characterized by at least one cam (102) having cam lobes adapted to mount at least two roller tappets (105) of two physically independent fuel pumps (104). Such a manner of mounting two physically independent fuel pumps (104) on a single cam (102) means that 10 this single cam (102) drives at least two physically independent fuel pumps (104). The fuel pump described above is a plug-in type fuel pump.
