High-pressure fuel pump arrangement for operating self-igniting internal-combustion engine, has low pressure and high pressure circuitry connected and cylinder head integrated in internal-combustion engine

摘要

#CMT# #/CMT# The high-pressure fuel pump arrangement has a low pressure and high pressure circuitry connected and a cylinder head (1) integrated in the internal-combustion engine. A pump piston (4) is operable by polygon formation (3) of valve cam shaft (2) mounted on the cylinder head. A feed pump (5) is coaxially integrated to the cam shaft for transportation of the fuel from a fuel tank into the cylinder head. #CMT#USE : #/CMT# High-pressure fuel pump arrangement for operating a self-igniting internal-combustion engine. #CMT#ADVANTAGE : #/CMT# The high-pressure fuel pump arrangement has a low pressure and high pressure circuitry connected and a cylinder head integrated in the internal-combustion engine, and hence ensures reduced number of construction units. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a high pressure fuel pump arrangement. 1 : Cylinder head 2 : Valve cam shaft 3 : Polygon formation 4 : Pump piston 5 : Feed pump 9 : Bearing surface.
