ABSTRACT:
A lubrication system for a multi-cylinder internal combustion engine has a valve drive mechanism equipped with a row of hydraulic valve lash adjusters installed in a cylinder head of an engine block of the engine and a camshaft with journals which is disposed over the cylinder head and is attached, at one end thereof, with a camshaft pulley coupled to a crankshaft pulley by a belt. The lubrication system includes a main oil gallery extending lengthwise in the engine body, a lash adjuster oil gallery formed in the cylinder head and extending along the row of hydraylic valve lash adjusters, and a camshaft oil gallery formed in the cylinder head and extending parallel to the lash adjuster oil gallery. The main oil gallery is connected independently to one end of the camshaft oil gallery adjacent the camshaft pulley and to one end of the lash adjuster oil gallery remote from the camshaft pulley so as to supply them with pressurized oil, fed by an oil pump, in opposite direction. The pressurized oil is carried, on one hand, to each camshaft journal through the camshaft oil gallery and, on the other hand, into a pressure chamber of each hydraylic valve lash adjuster through the lash adjuster oil gallery.
