Description
- The present invention relates to the field of motor vehicle internal combustion engines.
- More specifically, the invention relates to an oil pan of an internal combustion engine comprising means forming a baffle for the oil flow designed to keep an oil pump strainer immersed in the oil.
- An internal combustion engine usually comprises in its lower portion, also called the bottom of the engine, a cylinder block and an oil pan. An oil pump, driven by a crankshaft, draws up the oil stored in the bottom of the oil pan in order to send it, through an oil pump strainer, to moving elements of the engine such as for example the crankshaft bearings, the connecting rods or the pistons. The oil then returns by gravity to the oil pan.
- In operation, the engine generates vibrations which are propagated and can create unwanted noises in the engine. In order to attenuate the noise reverberated by the oil pan and stiffen the bottom of the engine, reinforcing the structure of the oil pan with stiffening ribs and/or adding a generally horizontal anti-surge plate mounted in the oil pan are known.
- However, such an anti-surge plate does not stiffen the bottom of the engine and at the same time create an oil volume stabilization zone in order to reduce the effects that roll can have on surging.
- An object of the invention is therefore to provide an oil pan in which the oil pump strainer is always immersed in order to prevent any surging.
- With this object in mind, the invention provides an oil pan of an internal combustion engine comprising means designed to keep the oil pump strainer immersed in the oil, said means comprising a first means belonging to the oil pan and a second means belonging to the anti-surge plate, said means forming a baffle for the oil flow.
- Such an oil pan advantageously has its side walls and its bottom stiffened, and at the same time allows the creation of an oil volume stabilization zone.
- The baffle thus created keeps the fluid near the strainer in various positions of the vehicle, the oil pump strainer being advantageously kept immersed in the oil and thus preventing any risk of surging.
- According to other features of the invention:
-
- the means forming a baffle for the oil flow can surround the oil pump strainer, the means belonging to the anti-surge plate and the means belonging to the oil pan being able to fit one inside the other;
- the lower ends of the means belonging to the anti-surge plate and the lower ends of the oil pump strainer can have a gap between them and the bottom of the oil pan;
- the means belonging to the anti-surge plate and the oil pump strainer can have generally the same height;
- the means belonging to the oil pan can comprise an opening at the bottom of the oil pan;
- the means designed to keep the oil pump strainer immersed can be of generally cylindrical shape and of different diameters;
- the means belonging to the oil pan can be a cylinder incorporated in the oil pan, and the means belonging to the anti-surge plate can be a cylinder incorporated in the anti-surge plate; and
- the means belonging to the oil pan can be a cylinder attached to the oil pan, and the means belonging to the anti-surge plate can be a cylinder attached to the anti-surge plate.
- The invention also relates to an internal combustion engine comprising an oil pan comprising such an oil pan.
- Other features and advantages of the invention will emerge clearly on reading the following description of the non-limiting embodiment of the invention, with reference to the attached drawings, in which:
-

FIG. 1 , is made in the shape of a reservoir or tray comprising a bottom which can be slightly inclined. The oil pan 1 comprises abottom 21 and side walls. The side walls comprise twolongitudinal side walls 220 and twotransverse side walls 221. - The oil pan 1 is intended to contain the oil required for the lubrication of the moving elements of the engine. This oil is pumped from the oil pan 1 through the
oil pump strainer 3, itself connected to an oil pump not illustrated inFIG. 1 . The oil used then drains under gravity from the moving or stationary elements of the engine to the oil pan 1 in which it is collected. - The oil pan 1 comprises an
anti-surge plate 2. Theanti-surge plate 2 is mounted in the oil pan 1 for example on one of thelongitudinal side walls 220, and extends parallel to thebottom 21 of the oil pan 1 generally as far as the side walls of the oil pan 1. Thus, once installed in the vehicle, the bottom of the oil pan 1 is parallel to the ground and theanti-surge plate 2 is parallel to the bottom of the oil pan 1 and the ground. - The
anti-surge plate 2 thus divides the oil pan 1 into achamber 23 lying between the upper edge of the walls 22 of the oil pan 1 and theanti-surge plate 2 on the one hand, and areservoir 24 constituting the lower portion of the oil pan 1 in the shape of a tray. - The
anti-surge plate 2 prevents on the one hand the oil contained in the oil pan 1 from coming in contact with moving elements such as for example the crankshaft, reduces the movement of the oil surface in the oil pan and therefore reduces surging and emulsification, and stiffens the walls of the oil pan 1. - The
anti-surge plate 2 comprises acavity 25 allowing anoil pump strainer 3 to go into thereservoir 24 of the oil pan 1. - The oil pan 1 comprises means 10, 20 forming a baffle for the oil flow which are designed to keep the
oil pump strainer 3 always immersed in the oil, under theanti-surge plate 2, in thereservoir 24.

The number ofopenings 11 can vary, thefirst cylinder 10 can comprise for example anopening 11 on a section which lies parallel to one of the twolongitudinal side walls 220 on the longitudinal axis of the vehicle, and anopening 11 on the section which lies parallel to the other oppositelongitudinal side wall 220. - The
first cylinder 10 advantageously stiffens thebottom 21 of the oil pan. - The
second cylinder 20 is incorporated in theanti-surge plate 2. It extends thecavity 25 of theanti-surge plate 2 continuously, and extends in the vertical direction, from theanti-surge plate 2 to thebottom 21 of the oil pan 1. - The
first cylinder 10 and thesecond cylinder 20 are of generally different diameters so that thesecond cylinder 20 of theanti-surge plate 2 lies inside thefirst cylinder 10 of the oil pan 1.

It will be understood that themeans 20 of theanti-surge plate 2 can lie outside themeans 10 of the oil pan 1, and that theoil pump strainer 3 can then pass inside themeans 10 belonging to the oil pan 1. - The lower ends of the
second cylinder 20 of the anti-surge plate and the lower ends of theoil pump strainer 3 have a gap between them and thebottom 21 of the oil pan 1. A minimum distance d must be maintained so as not to have any suction noise during the pumping of oil and thus prevent any contact with the oil pan 1. Thesecond cylinder 20 of theanti-surge plate 2 and theoil pump strainer 3 extending to the bottom of the oil pan 1 preferably have generally the same height so that the volume of oil for use is as large as possible. However, this arrangement is not compulsory. - The oil volume moves during acceleration, braking, and left or right cornering. An oil volume called the “surface intersection volume” is determined, this being the oil volume described by the intersection of the oil surfaces during acceleration, braking, and left and right cornering. Such an oil pan allows the strainer to be located in this surface intersection zone, which has not always been easy or possible. By placing the strainer in this zone, surging can then be prevented or delayed.
- Such an oil pan allows the baffle for the oil flow to keep the
