摘要： An oil treatment system for an internal combustion engine in one implementation includes an elongated dipstick tube defining a tube axis and a first flow passageway, a housing arranged on the dipstick tube and defining an internal cavity, an oil treatment apparatus disposed in the internal cavity, and a retainer coupled to the housing. The retainer may have a cylindrical body comprising an elongated first flow protuberance insertably received through the oil treatment apparatus to establish fluid communication between the oil treatment apparatus and the first flow passageway of the dipstick tube. The retainer comprises a cavity through which oil may be added directly to the first flow passageway of the dipstick which may be fluidly coupled to an oil sump of the engine. The oil treatment apparatus may be an oil filter. An oil treatment additive may optionally be added to the housing.

摘要： An oil passageway structure for internal combustion engines includes a cylinder head having an inter-bearing wall fluid communication oil passage for providing fluid communication between a plurality of bearing walls to allow oil to flow therebetween. The cylinder head further includes a bearing wall oil passage branched from the inter-bearing wall fluid communication oil passage to supply oil to a bearing surfaces of at least one of the bearing walls. The inter-bearing wall fluid communication oil passage is defined in one of facing side walls. The bearing wall oil passageway is defined in at least one of the bearing walls. The oil passageway structure is thus made up of a reduced number of parts, can be assembled with a reduced number of man-hours, can lead to productivity growth, and is inexpensive to manufacture.

摘要： Systems and methods are provided for a cylinder block having one or more bulkheads. The bulkheads provide a dual-wall structure that may enhance the stiffness of the cylinder block in bending and torsion. The bulkheads may also provide an oil drain to allow oil to directly drain through a hollow core of the bulkhead. An overflow outlet may be formed in an inner wall of a bulkhead. In some implementations, a cylinder block with bulkheads may increase an oil capacity of an engine.
