Embodiment Construction

[0016] The invention provides an engine having a cylinder head assembly. The cylinder head assembly may include a cover having an opening. An oil routing plug may be disposed in the opening and include a plug oil passage configured to receive oil from the engine lubrication system and to flow the oil to a journal adjacent a journal bearing rotatably connected to the camshaft oil channel. It should be understood that in other embodiments, the opening may accommodate other components. For example, a solenoid valve can be positioned in the opening. In this way, the cylinder head assembly can be improved at a later stage of production, increasing the applicability of the cylinder head and reducing the manufacturing costs of the engine.

[0017] Figure 1-3 A schematic diagram of three embodiments of a vehicle 50 including an engine 100 is shown. The three embodiments of the vehicle 50 having the engine 100 may include common components, and thus like components are numbered ac...

Abstract

The invention relates to a cylinder head assembly having an oil routing plug. An engine provided herein. The engine includes a cylinder head assembly, a cap including an opening, an oil routing plug positioned in the opening including a recess traversing the plug, the recess and a portion of the wall of the opening defining a boundary of a plug oil passage, and an oil supply passage extending through the cylinder head assembly including an inlet fluidly coupled to a lubrication circuit and an outlet opening into the recess.

Description

technical field Background technique [0001] Variable cam timing is used in engines to improve combustion efficiency over a wide range of engine operating conditions. For example, intake and / or exhaust valve timing may be advanced or retarded based on various operating conditions such as engine temperature, desired power output, revolutions per minute (RPM), etc. to improve combustion efficiency. As a result, the power output of the engine can be increased and emissions can be reduced. Openings for components such as cam timing solenoids and other components for controlling cam phasers configured to vary the timing of intake or exhaust camshafts may be integrally formed in the cylinder head. Specifically, openings for solenoid valves and / or oil feed lines may be machined or cast into the cylinder head to route oil to the cam phaser. [0002] However, the present inventors have recognized several disadvantages due to casting and machining the aforementioned features into the...
