An intake swirl gasket is disclosed herein. It is installed between a cylinder head and an intake manifold and comprises plural airflow holes for respectively communicating with plural intake passages of the cylinder head; and plural diversion devices respectively disposed in the plural airflow holes and each having an axis and plural splitter blades extended from the axis for connecting to an inner wall of each of the plural airflow holes, wherein each of the plural splitter blades is shaped as an arc to form a recessed surface towards the intake manifold at one side thereof and a convex surface towards the cylinder head at the other side thereof, and wherein an included angle between each of the plural splitter blades and an end face of the intake swirl gasket oriented towards the cylinder head ranges from 50 to 80 degrees.

The present disclosure provides sufficient support rigidity of a supercharger and an intercooler, while reducing an increase in the overall height of an engine. The supercharger extends along a cylinder bank at a side of a surge tank, and is fixed to an intake manifold. The intercooler is located below the supercharger. A case of the intercooler is connected to a discharge port of the supercharger and an intake air introduction pipe of the intake manifold.

A hybrid vehicle includes: a crankcase extending from a lower portion of a cylinder of an engine, the crankcase including a main body portion defining a crank chamber in which a crankshaft of the engine is accommodated, the crankcase further including a breather portion projecting upwardly from the main body portion and defining a breather chamber into which blowby gas is introduced from the crank chamber; a breather tube that introduces the blowby gas from the breather chamber into the intake passage; and a drive motor disposed rearwardly of the cylinder and mounted on a top surface of the crankcase. The breather portion has a facing surface facing an outer peripheral surface of the drive motor. The facing surface of the breather portion is shaped to conform to the outer peripheral surface of the drive motor.

An elastic connecting support for arrangement between a combustion engine and an air filter of a handheld work apparatus is disclosed. The connecting support has a first channel for largely fuel-free air and a second channel for a fuel/air mixture. The connecting support is realized as a single piece, and has, on a first side, an engine connecting flange, at which the first and second channel end, for connection to the combustion engine. The first channel has a first peripheral wall and the second channel has a second peripheral wall. The first peripheral wall and the second peripheral wall are arranged at a distance in relation to each other in a longitudinal section of the connecting support. The channels extend from the first side to a second side of the connecting support. On the second side, the first channel and the second channel end at a common connecting flange.

A cooling device includes a surrounding member, an air inlet, an air outlet, and a flow-path-formation mechanism. The surrounding member is configured to surround an engine. The air inlet is formed in the surrounding member. The air outlet is formed in the surrounding member and is to be coupled to an intake pipe of the engine. The flow-path-formation mechanism is configured to form a flow path that allows outside air to circulate to the air outlet from the air inlet when a temperature of the engine or a temperature inside the surrounding member is greater than or equal to a predetermined temperature.

A side-by-side vehicle comprises a vehicle body frame including a cabin frame part surrounding a riding space in which seats for a driver and a passenger are provided; an engine which is mounted on the vehicle body frame and generates driving power for allowing the side-by-side vehicle to travel; an air-intake unit including in an inside thereof, an air-intake passage through which intake-air flows to the engine, and an air inlet through which the intake-air is introduced into the air-intake passage; and a cargo carrier having a loading space with a depressed shape in a state in which the cargo carrier is supported by the vehicle body frame, and the air-intake unit is disposed so that the air inlet is directed downward and faces a surface of the cargo carrier.

A screw connection system connecting a plastic component with a metal component has a bushing and a screw with a screw shank and an external thread arranged on the screw shank. The screw is captively guided in the bushing. The bushing, in a screw-connected state of the screw connection system, extends with a first section in a bore of the plastic component and with a second section in an aligned bore of the metal component aligned with the bore of the plastic component. The bore of the plastic component and the aligned bore of the metal component are positioned at an angle relative to a vertical line on joining surfaces of the plastic component and of the metal component adjoining each other in the screw-connected state. The bushing is movable out of the plastic component when screwing the screw into the metal component.

A hybrid vehicle includes: a crankcase extending from a lower portion of a cylinder of an engine, the crankcase including a main body portion defining a crank chamber in which a crankshaft of the engine is accommodated, the crankcase further including a breather portion projecting upwardly from the main body portion and defining a breather chamber into which blowby gas is introduced from the crank chamber; a breather tube that introduces the blowby gas from the breather chamber into the intake passage; and a drive motor disposed rearwardly of the cylinder and mounted on a top surface of the crankcase. The breather portion has a facing surface facing an outer peripheral surface of the drive motor. The facing surface of the breather portion is shaped to conform to the outer peripheral surface of the drive motor.

A vehicle air intake assembly is disclosed. The assembly includes a base member having an aperture configured to allow air to flow through the base member and into an engine and an outer member spaced from the base member to position an air filter between the outer member and the base member.

An air intake circuit for a heat engine is intended to be positioned between an air compression element and at least an upper portion of a hollow combustion chamber in a cylinder head of the engine. The air intake circuit includes the cylinder head, an air intake manifold, and at least one air intake duct. The circuit also includes at least one concave receptacle turned towards the outside of the engine, housed in a cavity of the cylinder head, and connected to a tubular element pushed into the at least one air intake duct.
