Abstract

This invention relates to a sump for an internal combustion engine and a method for draining a sump. In prior sumps, a drain aperture was commonly provided in the floor of the sump to provide good draining characteristics. Where a drain aperture in the sump floor was not practical, a side wall drain aperture was used, but with less than desirable draining characteristics because the drain aperture was above the sump floor for structural reasons. In accordance with this invention, the sump floor has at least one gutter. A closable drain aperture is located such that at least its lowermost part is located within the gutter. When the drain aperture is opened, oil within the sump can flow along the gutter and through the aperture. The gutter may form a support rail to support the weight of an engine.
