A temperature control throttle device is provided. The temperature control throttle device includes: at least one throttle; a first pipeline and a second pipeline, wherein, the first pipeline and the second pipeline are connected to the same side of the at least one throttle in an air flow direction in parallel, and wherein the second pipeline is provided with a heat exchanger that heats air flowing through the second pipeline with engine coolant, engine oil or engine exhaust gas as a heat source.

Methods and systems are provided for a hydrocarbon (HC) trap system in an engine air induction system. In one example, a system may include a pillow-case type HC trap housed in a rectangular opening formed in a wall of an air conduit at the outlet of an air cleaner box. A frame may be integrally formed around the opening to support the HC trap protruding outward from the wall.

A gas-liquid separator includes a cylindrical inlet pipe and a fluid inflow pipe. The inlet pipe includes a fluid inlet which is formed in a fluid entering side and radially opens. An axis line of the inlet pipe horizontally extends. The fluid inflow pipe includes at an end a connection opening connected to the fluid inlet. An axis line of the fluid inflow pipe horizontally extends. The fluid inflow pipe introduces the gas-liquid two-phase fluid through the fluid inlet from a side of the inlet pipe. In a connecting portion, a position of an axis line extending through a center of a connection opening in communication with the fluid inlet is vertically offset with respect to a position of the axis line of the inlet pipe.

A sleeve structure comprises a plurality of sleeve main bodies fitted respectively into intake ports of a cylinder head of a multi-cylinder internal combustion engine and a shared base provided on one end of the plurality of sleeve main bodies. By fixing this sleeve structure to the cylinder head, an amount of labor involved in a fixing operation for fixing sleeves to a cylinder head is reduced.

A combination cooling/filtration device is for cooling and filtering lubricant in an outboard motor. The device includes a body; a lubricant cooler configured to cool the lubricant, the lubricant cooler having an inlet port that receives cooling fluid and an outlet port that discharges the cooling fluid; a filter configured to filter the lubricant; and a lubricant passage extending through the body. The lubricant passage is configured to convey the lubricant from upstream to downstream, and in particular to the lubricant cooler, then to the filter, and then to an engine of the outboard motor. The body is axially elongated from top to bottom, the filter is mounted on the top of the body, and the lubricant cooler is located in the body below the filter.

Systems are disclosed for power systems and enclosures having an improved compressor drive. In examples, a power system includes a generator to be driven by an engine. The generator is coupled to the engine on a first side of the generator and has a clutch extending from a second side of the generator opposite the engine. The clutch is coupled to the engine. A compressor is positioned at the second side of the generator opposite from the engine. The compressor comprising a shaft extending toward the generator and configured to be driven by the clutch.

A physical quantity measuring device is configured to measure a physical quantity of a fluid. The physical quantity measuring device includes: at least two humidity detection parts configured to output a humidity signal corresponding to a humidity of the fluid; and an abnormality determination part configured to determine that an abnormality has occurred in the humidity detection parts in response to that a difference between the humidity signals obtained from the two humidity detection parts exceeds an abnormality determination threshold.

The invention relates to a fluid pipe arrangement (100), in particular for a charged air duct of an internal combustion engine, comprising a housing (10) having a longitudinal extension (L). The housing (10) includes a first fluid duct (20) having a first fluid inlet (22) and a first fluid outlet (24) for a first fluid and at least one second fluid duct (30) having a second fluid inlet (32) and a second fluid outlet (34) for a second fluid. Thermal insulation means (40) are provided between at least a portion (38) of the second fluid duct (30) and at least a portion (28) the first fluid duct (20).

A cooling air feeding apparatus is for a motor vehicle, which has a motor vehicle body and a drive train, the drive train being assigned a cooler, and at least the cooler being arranged in a rear region of the motor vehicle body. The cooling air feeding apparatus has a throughflow opening, which is in the rear region and which is configured to receive air from surroundings of the motor vehicle and to feed the received air to the cooler. In order to regulate a driving state of the motor vehicle, the throughflow opening is configured with a variable throughflow cross section with the aid of a closing element, which is assigned to the cooling air feeding apparatus. The throughflow opening is configured to be controllably closed individually completely or partially and to be opened completely.
