Abstract
The invention relates to an engine oil system (1, 1′, 101) for supplying oil to oil using components (3) in a vehicle (800). The engine oil system comprises an oil pan (10) for holding oil received from the oil using components, an oil pump (20) fluidly connected to the oil pan for pumping oil from the oil pan to the oil using components, and an oil filter (30, 30′ 130) configured for cleaning the oil. The oil filter has a filter inlet (32, 32′, 132) for receiving oil to be cleaned, and a filter outlet (34, 34′ 134) for discharging oil from the oil filter. The oil filter is arranged in the oil pan such that, in use, the filter outlet discharges oil into the oil pan.
Claims23
An engine oil system for supplying oil to oil using components in a vehicle, said engine oil system comprising:
- an oil pan for holding oil received from said oil using components, an oil pump fluidly connected to said oil pan for pumping oil from said oil pan to said oil using components, and an oil filter configured for cleaning said oil, said oil filter having a filter inlet for receiving oil to be cleaned, and a filter outlet for discharging oil from said oil filter, wherein said oil filter is arranged in said oil pan such that, in use, said filter outlet discharges oil into said oil pan, wherein said oil filter comprises a filter insert for cleaning said oil, and wherein said engine oil system comprises a filter lid arranged to close an opening in a housing of the oil pan, wherein said oil filter can be accessed by removing said filter lid whereby said filter insert can be removed via said opening, characterized in that, said filter insert comprises a plurality of filter elements connected to each other, said filter elements being arranged successively from said filter inlet to said filter outlet, wherein said oil filter is configured and arranged to enable removal of a filter element from said plurality of filter elements and/or addition of a filter element to said plurality of filter elements.
A lid, such as e.g. a filter lid, for closing an opening in an oil pan, said lid comprising:
- an expandable closing arrangement for closing the opening in said oil pan, a first elongated element having a first element connecting portion connected to first portion of said closing arrangement by a first pivotable connection, a second elongated element having a second element connecting portion connected to a second portion of said closing arrangement by a second pivotable connection distant from said first pivotable connection, wherein said first elongated element and said second elongated element are connected to each other by a pivotable jointer enabling said first elongated element and said second elongated element to be arranged:
- in a first relative position in which the first pivotable connection is separated from said second pivotable connection by a first distance which the expandable closing arrangement is in a first state in which the closing arrangement can pass through said opening, and in a second relative position in which the first pivotable connection is separated from said second pivotable connection by a second distance being greater than said first distance in which the expandable closing arrangement is in a second state, or an expanded state, in which the closing arrangement cannot pass through said opening.
