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

Abstract: An internal combustion engine includes a cylinder defining a combustion chamber enclosed by a cylinder wall, a piston that is arranged inside the combustion chamber and moveable in a reciprocating motion away from and towards a crankshaft, and at least one first scraper ring defining an oil scraper ring that is arranged between the piston and the cylinder wall and configured to scrape oil off from the cylinder wall when the piston moves towards the crankshaft. The internal combustion engine further includes at least one second scraper ring defining a condensation fluid scraper ring that is arranged between the piston and the cylinder wall and configured to scrape a condensation fluid off from the cylinder wall when the piston moves away from the crankshaft.

Abstract: A system and method for separating parts of a liquid based or depending on gas content is disclosed herein. The system, in an embodiment, comprises a pressure chamber, an inlet through which liquid is pumped into said chamber, a first liquid outlet connected to an upper part of said pressure chamber, and a second liquid outlet connected to a lower part of said pressure chamber. The first and second liquid outlets comprise a first valve element and a second valve element, respectively, that are configured to control the pressure inside said pressure chamber. While under pressure, a first subpart of the liquid inside said pressure flows out of the first liquid outlet, and a second subpart of the liquid inside said pressure flows out of the second liquid outlet. The first subpart has a greater percentage of gas content than the percentage of gas content, if any, in the second subpart.

Abstract: 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.

Abstract: A fluid filtration assembly (FFA) includes a housing having a thickness defined between an internal surface and an external surface, the housing receiving a filter and defining an outer annular flow passage between an outer surface of the filter and the internal surface of the housing; an inlet pipe communicates with the FFA and injects a fluid into the housing to impart a centrifugal force; an outlet pipe communicates with the FFA and discharges the fluid from the housing; and a collection area disposed towards an end of the outer annular flow passage collects particulate matter from the fluid; wherein a width of the outer annular flow passage increases towards the collection area.

Abstract: An oil filtration system includes an oil chamber inlet. Also included is a first screen defining a first chamber volume that receives an oil flow from the oil chamber inlet, the first screen having a first mesh coarseness. Further included is a second screen surrounding the first screen to define a second chamber volume surrounding the first chamber volume, the second screen having a second mesh coarseness that is greater than the first mesh coarseness. Yet further included is at least one exit nozzle having an exit cross-sectional area that is greater than or equal to a cross-sectional area of apertures of the second screen. Also included is a bypass valve disposed in a first position during a first pressure condition within the first chamber volume and in a second position during a second pressure condition within the first chamber volume.
