The system includes a control unit communicatively coupleable to the expansion pack having a processor, a display unit, and a storage. The processor executes a control application configured to receive the at least one of the measured operational parameter or representation thereof.

An internal combustion engine (1) includes an internal combustion engine main body (20), a head cover (11, 15) attached to an upper end part of the internal combustion engine main body, and an exhaust system (34) connected to the internal combustion engine main body, and a gas-liquid separator (45, 60) for blowby gas provided in the head cover. A part of the exhaust system is positioned adjacent to the internal combustion engine main body in a first direction (X) along a cylinder row, and the gas-liquid separator is positioned in the head cover so as to be offset in the first direction.

An oil separation assembly for use in a high pressure reciprocating compressor is provided. The compressor includes a suction chamber, a crankcase chamber, and at least one partition member at least partially separating the suction chamber and the crankcase chamber. The at least one partition member further includes at least one opening. The oil separation assembly comprises at least one demisting structure positioned within the crankcase chamber adjacent the at least one partition member at the at least one opening; and at least one securing structure secured in operable relation with the at least one demisting structure so as to secure the at least one demisting structure relative to the opening. The oil separation assembly can further include a second demisting structure positioned within the suction chamber adjacent the at least one partition member at the at least one opening.

A motorcycle supercharger (42) pressurizes intake air (I) for a combustion engine (E). The supercharger (42) includes a centrifugal impeller (50) and an impeller casing (52) which covers the impeller (50). The impeller casing (52) includes an outer peripheral wall (84) located radially outward of the impeller (50) and a side wall (86) located axially outward of the impeller (50). Reinforcing first and second side wall ribs (94, 96) are provided at the side wall (86) of the impeller casing (52).

A work vehicle includes an engine, an intake passage through which combustion air flows from an ambient air inlet to an engine, an air cleaner for removing dust contained in the combustion air, a throttle valve for adjusting an intake amount of the combustion air by the engine, a blowby gas returning passage for returning blowby gas discharged from the engine to a mid portion of the intake passage, and an inclined passage portion that assumes a progressively downwardly inclined posture to be located at a lower position on downstream side in a flow direction, the inclined passage portion having a water draining portion at its lowermost end.

An oil separator is provided with a case that has an air inlet and a plurality of expansion chambers formed within the case. Air that contains oil is introduced into the case via the inlet and caused to strike a impingement plate to thereby separate the oil from the introduced air and recover the oil. The transverse cross-sectional area of each expansion chamber is greater than the open area of the inlet. Partition walls with orifice holes formed therein are provided between the expansion chambers.

A separator for separating liquid from a gas flow is provided with a nozzle carrier element provided with a nozzle arrangement having one or more nozzles. An impact element is arranged downstream in flow direction of the gas flow at least partially opposite the nozzle arrangement. A permanent cover device is provided that covers at least one of the one or more nozzles of the nozzle arrangement. The permanent cover device reduces by at least 50% a through-flow of the gas flow through the at least one of the one or more nozzles of the nozzle arrangement compared to the one or more nozzles of the nozzle arrangement that are free from the permanent cover device. An assembly kit for producing such a separator is provided with a nozzle carrier element with nozzle arrangement and one or more nozzles, an impact element, a cover device, and a liquid reservoir.

An engine device with high reliability and high safety even in use in cold regions, especially in arctic regions at 20 C. or less, the engine device including: a heating portion (21, 22, 23, 24, 25, 26) configured to increase a temperature in a mixed region where an intake air flowing in a blow-by gas mixed joint (20, 20A, 20B, 20C, 20D) and a blow-by gas introduced from a returning hose (12) are mixed; and/or a pressure regulation portion (121, 125) having a blow-by gas passage in which the blow-by gas from a combustion chamber flows.

An oil circulation system and method for continuously purifying engine oil including an engine operably connected to an oil reservoir, wherein at least one stream of oil is conveyed from the oil reservoir to the engine via a conduit, and circulated through the engine and conduit via engine operating pressure and/or one or more pumps, and at least one membrane unit positioned in a path of the oil stream such that oil containing dissolved/emulsified droplets of water is fed continuously through the membrane unit. A cross flow hollow fiber module adapted to be positioned in a system for continuously purifying engine oil, the hollow fiber module having a central feed distributor tube, hollow fiber membranes positioned around the central feed distributor tube, end caps with ports for receiving and emitting a flow of sweep air, and optionally a shell casing, wherein the central feed distributor tube includes openings sized and positioned to allow oil to flowing into the feed distributor tube to flow out radially.

A supercharging system for a combustion engine of a motorcycle includes a supercharger which pressurizes intake air and supplies the intake air to the combustion engine, an air intake chamber which is connected to downstream of the supercharger, a relief passage which relieves the high-pressure intake air within the air intake chamber, and a relief valve which is provided on the relief passage. The air intake chamber is disposed above the combustion engine, and the relief passage is disposed below an upper end of the air intake chamber. The relief passage is connected to a front surface of the air intake chamber.
