A system for circulating coolant including a coolant manifold and a coolant filter housing. The oil cap and the oil transfer tube act in conjunction to redirect the oil flow. The coolant manifold is able to redirect coolant to the coolant filter and back into the system. The coolant filter is able to filter coolant in the system.

A liquid filter module may include a filter device and a heat exchanger coupled thereto via an intermediate piece. At least one liquid channel and a receiving channel crossing the at least one liquid channel and configured to receive a valve may be disposed in the intermediate piece. The receiving channel may include a channel which crosses the receiving channel and in which a securing element may be arranged which fixes the valve.

The control shaft (20) of a variable compression ratio mechanism is coordinated with the auxiliary shaft (25) of an actuator device (1) through an intermediate link (31). The housing (5) of the actuator device (1) has on the lower surface thereof an oil filter mounting seat section (36), and a stopper section (37) is formed integrally with the oil filter mounting seat section (36). A second arm (28) of the auxiliary shaft (25) comes in contact with the stopper section (37) to define the limit of the compression ratio on the low compression ratio side. The stopper section (37) has high rigidity because the oil filter mounting seat section (36) having high rigidity and the stopper section (37) are integrated together.

A structural frame is provided. The structural frame includes a bottom surface, first and second cylinder block sidewall engaging surfaces, the first and second cylinder block sidewall engaging surfaces positioned above the bottom surface at a height that is above a centerline of a crankshaft support included in a cylinder block when the structural frame is coupled to the cylinder block.

Techniques for managing a lubricant fluid include storing a lubricant fluid that includes liquid water in an interior volume of a reservoir, which includes a vapor space above the lubricant fluid that encloses water vapor; circulating, with a blower, a first airflow from the vapor space to an ambient environment to remove at least a portion of the water vapor to the ambient environment; circulating a second airflow to a heater in fluid communication with the vapor space within the interior volume of the reservoir; heating the second airflow with the heater; circulating the heated airflow into the vapor space to reduce a relative humidity of the vapor space; and releasing at least a portion of the liquid water from the interior volume of the reservoir through a control valve coupled to the reservoir.

The present invention is directed to a rebuildable engine casing for an internal combustion engine supporting a plurality of pistons. The engine casing forms and provides a novel oil squirter that can readily be serviced or rebuilt. The engine casing also includes a novel mechanism for separating the case members and a removable service plug for accessing the oil galleries. The present invention also provides for a rebuildable oil squirter.

A valve group (10) is housed in a duct (40) of a pressurized oil circuit of a vehicle. The valve group (1) extends along an axis (X-X) including a valve body (11) axially fixed to the conduit (40) and an obturator (15) fitted axially movably, on the valve body (11). The obturator (15) has an exchanger aperture (153) through which oil flows to a heat exchanger (3) in the circuit and an auxiliary aperture (152) through which the oil flows to an auxiliary component of the circuit. The valve group (10) includes a pair of elastically yieldable elements (180) of a material selected from among the shape-memory alloys, operatively connected between the valve body (11) and obturator (15), and suitable, as a function of the oil temperature and/or the oil pressure, to axially move and to maintain the obturator (15) in a predefined axial position.

An engine device including, a cylinder block (6) having one side portion to which a flywheel that is rotated integrally with a crankshaft (5) is disposed. The engine device is provided with a starter (20) that transmits a rotational force to the flywheel at a time of engine start. A flywheel housing (7), which accommodates the flywheel and includes a starter attachment pedestal for attaching the starter (20), is attached to the one side portion of the cylinder block (6). The starter (20) is disposed inner side of the engine than a portion of the flywheel housing (7), the portion being located outermost in the engine with respect to a direction that is perpendicular to a direction along a crankshaft center (300) and that is parallel to the cylinder head joining surface (341) of the cylinder block (6).
