Embodiment Construction

[0009] figure 1 A drive system 5 is shown having an internal combustion engine 10 which is connected to an exemplary embodiment of a fuel system 12 . Those skilled in the art will appreciate that the engine 10 may be any type of internal combustion engine, such as a diesel engine, a gasoline engine, a gas fuel engine, a heavy fuel engine, or any other type of engine known to those skilled in the art.

[0010] Engine 10 may include an engine block 14 defining a plurality of cylinders 16 , a piston 18 slidably disposed within each cylinder 16 , and a cylinder head 20 coupled with each cylinder 16 . Cylinder 16 , piston 18 and cylinder head 20 may form a combustion chamber 22 . In the illustrated embodiment, engine 10 includes six combustion chambers 22 . However, engine 10 may include a greater or lesser number of combustion chambers 22 . Additionally, the combustion chambers 22 may be arranged in an "in-line" or "V" configuration, or any other suitable configuration. In som...

Abstract

A fuel system (12) for an engine (10) is disclosed. The fuel system includes a common rail (34), and a cylinder head (20) having a first bore (46) and a second bore (52) intersecting the first bore. A fuel injector (32) is coupled to the cylinder head and at least partially received within the first bore. The fuel system also includes a one-piece hollow tube (48), extending linearly from the common rail to the fuel injector through the second bore. The one-piece hollow tube is configured to communicate high pressure fuel from the common rail to the fuel injector.

Description

technical field [0001] The present invention relates to fuel systems, particularly fuel systems having a one-piece hollow tube connection. Background technique [0002] Fuel systems typically use multiple fuel injectors to inject high pressure fuel into the engine's combustion chambers. This high pressure fuel is supplied to the fuel injectors through a common rail secured to the engine and separate fuel lines connected between the common rail and the fuel injectors. Due to the geometry of the engine and / or other components associated with the engine, fuel lines often have bends and must be fabricated from thin-walled materials that can withstand the bends during manufacturing without breaking. While suitable for many applications, this fuel system configuration is not suitable for higher pressure applications. Specifically, the strength of the material used to connect the common rail to the fuel injectors is a factor that limits the maximum operating pressure of these fue...
