Engine oiling system
Present embodiments relate to an engine oiling system. More specifically, but without limitation, present embodiments relate to an engine oiling system which provides a lower profile for the engine within the engine compartment.
1 . An oiling system for a combustion engine, comprising:
a timing cover;
an oil pump which is mounted to said timing cover, said oil pump being a gerotor pump that is configured to be directly driven by a crankshaft;
said oil pump having an oil input, an oil output port adjacent to said oil input, and an external access port which allows for pressure adjustment therein;
an oil pan having a first end connected to a lower edge of said timing cover, a second end defining a sump, and integrally formed oil passages located between said first end and said second end, wherein said oil passages include an input passage and an output conduit; and
said oil pump disposed adjacent to said first end of said oil pan and in fluid communication with said oil passages.
2 . The oiling system of claim 1 , further comprising said oil passages being cast-in oil passages in the oil pan.
3 . The oiling system of claim 2 , said cast-in oil passages in flow communication with ports of said oil pump.
4 . The oiling system of claim 3 , further comprising a gasket disposed between said ports of said oil pump and cast-in passages of said oil pan.
5 . The oiling system of claim 1 , said oil pump disposed on a rear side of said timing cover.
6 . The oiling system of claim 1 further comprising said external access port formed in said oil pump and aligned with an access port in said oil pan.
7 . The oiling system of claim 1 , said oil pan having the external access for an oil pump pressure control spring in said external access port of said oil pump.
8 . The oiling system of claim 1 , said oil pump positioned for and capable of being driven by said crankshaft of said combustion engine.
9 . The oiling system of claim 1 , said oil pump being directly driven by said crankshaft.
10 . The oiling system of claim 9 , further comprising an adapter positioned within said oil pump and capable of receiving said crankshaft.
11 . The oiling system of claim 10 , said adapter causing rotation of said oil pump at a same speed of said crankshaft.
12 . The oiling system of claim 1 , said combustion engine being a FORD 7.3L gasoline engine.
13 . The oiling system of claim 1 , further comprising a drive on said crankshaft and engaging said oil pump.
14 . The oiling system of claim 1 , said oil pump comprising a housing and first and second internal rotors.
15 . The oiling system of claim 1 , said oil pan further comprising a windage tray.
16 . A method of installing an oiling system, comprising the steps of:
removing a first oil pan and a first timing cover from a combustion engine having a first oil pump spaced from said first timing cover toward a rear of said first oil pan;
installing a second oil pump to a second timing cover toward a front of a second oil pan, said second oil pan having a reduced depth dimension, and said second oil pump having an input port, an output port and an external access port for pressure adjustment;
connecting said second oil pump to ports in said second oil pan, said ports being in fluid communication with integrally formed oil passages in said second oil pan, and said oil passages comprising an input passage and an outlet passage; and
installing said second oil pan to said combustion engine to provide a reduction in total height of the combustion engine, wherein the input port and output port are adjacent to each other, and wherein the second oil pump is a gerotor pump that is directly driven by a crankshaft of the engine.
17 . The method of claim 16 , said combustion engine being a FORD 7.3L gasoline engine.
18 . The method of claim 16 , said oiling system being a front drive system.
