A carburetor includes a body and a fuel bowl coupled to the body. A fuel bowl chamber is defined by the body and the fuel bowl. A fuel supply passageway fluidly couples a fuel supply inlet of the carburetor with the fuel bowl chamber. A fuel metering unit is coupled to the body of the carburetor. A first filter is disposed in one of the fuel supply passageway and the fuel bowl chamber, and a second filter is disposed in the fuel metering unit.

An attachment structure for a solenoid valve which can be stably attached to and removed from a carburetor unit with a single movement and without increasing the number of parts. A rod-like supporting portion is disposed a predetermined distance away from a surface of a carburetor unit and extending in a direction substantially perpendicular to a direction of and installed near an opening in the surface of the carburetor unit. A cylindrical engaging portion extends from a circumferential face of a cylindrical body fitted on the solenoid valve substantially perpendicular to an axial line of the rod-like supporting portion, and forms a groove-like engagement portion which is narrower in diameter than the rod-like supporting portion, whereby the engaging portion, via the groove-like engagement portion, is coupled to and supported by rod-like supporting portion when an insertion portion of the solenoid valve is inserted into the opening.

A suction tube of a stratified scavenging engine that can improve the flexibility in designing the shapes and layouts of an air-fuel mixture passage and an air passage; allow for continuous and smooth changes in the shapes of the cross sections of the air-fuel mixture passage and the air passage from the inlet side toward the outlet side; reduce the number of components; and facilitate attachment and assembly; and that is also advantageous in terms of cost is provided. The suction tube includes an air-fuel mixture passage and an air passage, inlet and outlet sides of the passages being connected to a carburetor and a cylinder, respectively; a cylindrical exterior member that mainly forms an outer perimeter portion of each of the air-fuel mixture passage and the air passage; and an interior member for dividing the inside of the cylindrical exterior member into the air-fuel mixture passage and the air passage. With the use of elastic deformation of the interior member or the cylindrical exterior member, the interior member is attached to and integrally formed with the inside of the cylindrical exterior member.

The present invention involves providing a viscous fluid in a particular format and implementations thereof. In particular, a viscous slave fluid is provided in a particular format, wherein the particular format can be an end result or an intermediate result for the viscous fluid. In the case of an intermediate result, the viscous fluid in the second format may be further processed to a third format. Implementations or applications include supercharged fuel injection systems, methods, and apparatuses for internal combustion, lean-burn oil pre-mixing systems, methods, and apparatuses for liquid fuel combustion, and medical or biomedical devices, systems, and methods.

A saddled vehicle includes a rear fender that is arranged along an outer circumferential side of a rear wheel, a chamber portion that is arranged on a front side of the rear wheel and is provided on the outer circumferential side of the rear wheel from a mudguard surface of the rear fender facing the rear wheel, and an atmospheric air introduction pipe that is connected to the chamber portion and introduces atmospheric air to a canister.

An internal combustion rotary engine includes an air passage configured to allow cool air to flow through the rotor as the rotor moves relative to the housing within the engine. Some embodiments include a removable fuel cartridge.

A tanker vehicle for distributing liquid on a surface includes a chassis that supports a tank for holding the liquid. A fluid pump discharges the liquid from the tank and is driven by a hydraulic motor. A hydraulic system delivers hydraulic fluid to the motor through a supply line and returns the fluid to a tank through a return line. A bypass circuit is disposed between the supply line and the return line, bypassing the motor. The bypass circuit includes a system for providing a combination soft start and soft stop of the hydraulic motor that is configured to enable hydraulic fluid to flow from the supply line through the bypass circuit to the return line at a start of the hydraulic system and to flow from the return line through the bypass circuit to the supply line at a shutdown of the hydraulic system.
