An air intake assembly has an inlet member, a fluid reservoir, and an outlet. The inlet member defines a generally vertical oriented first fluid channel. The first fluid channel has a vertically extending portion, an upper inlet end, and a lower end. The fluid reservoir has an upper region that defines a second fluid channel. The fluid reservoir is attached to a lower end of the inlet member such that the first fluid channel vertically extending portion is substantially perpendicular to the second fluid channel. The fluid reservoir has an outlet defined by an aperture in a lower region of the fluid reservoir which forms a liquid collector. The trapdoor is pivotably attached to the fluid reservoir adjacent to the outlet. The rigid trapdoor is configured to open when exposed to a predetermined open force value to allow liquid to escape the liquid collector.

A system for introducing a gaseous fuel to an internal combustion engine includes a fuel storage device, a compressor, and an air and fuel conduit in fluid communication with the fuel storage device and with the compressor. The air and fuel conduit includes a first passage and a second passage that includes a first portion and a second portion, the second portion being a venturi portion, the second passage being fluidly connected to the compressor in parallel with the first passage.

A vehicle includes an internal combustion engine and an air induction system configured to provide intake air to the internal combustion engine. The air induction system includes an intake port, an air box coupled to the intake port and having a wet side air box and a dry side air box, at least one sensor disposed within the air box and configured to detect a presence or level of liquid within the air box, and a watertight door disposed within the air box and configured to move between an open position that allows air to pass through the air box dry side, and a closed position that facilitates preventing liquid from passing into the air box dry side.

A method for producing liquefied gases includes providing an internal combustion engine with at least one cylinder and an exhaust manifold, providing a flow circuit, which includes the cylinder and connects an air inlet to the exhaust manifold, conveying air along the flow circuit according to a flow direction from the air inlet towards the exhaust manifold, compressing the air along a portion of the flow circuit, and liquefying at least one gaseous component of the compressed air.

Check valve inserts define a valve seat for an open position of a check valve and have an outer support seatable in an internal chamber of the check valve and have an inner annular ring spaced radially inward from the outer support by a rib that angles axially toward a central longitudinal axis to position an upper surface of the inner annular ring a distance axially beyond an upper surface of the outer support. Check valves have a housing defining an inlet port, an outlet port, and a chamber in fluid communication with the inlet and outlet ports, have the check valve insert seated with the chamber, and have a seal disc moveable within the chamber between the open position defined by the inner annular ring of the check valve insert and a closed position. The seal disc is translatable in response to a pressure difference across the seal disc.

A system for forming a negative pressure in a negative pressure reservoir of a brake system includes, an engine having an intake manifold and a camshaft, a vacuum pump connected to the camshaft through a clutch device and generating a pump negative pressure, a turbocharger having a compressor supplying a compressed air to the engine, a pump negative pressure line connecting the vacuum pump and the negative pressure reservoir and supplying the pump negative pressure to the negative pressure reservoir, an intake negative pressure line connecting the negative pressure reservoir and the intake manifold and supplying the intake negative pressure of the intake manifold to the negative pressure reservoir, and a negative pressure source selection apparatus configured to control opening and closing of the pump negative pressure line and the intake negative pressure line based on operation of the turbocharger.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

A carburetor base of an engine defines an axial through hole and a pulsation hole channel. An anti-blocking component is mounted inside the axial through hole and defines an air inlet channel. The air inlet channel communicates with the pulsation hole channel so as to avoid blocking of condensed fuel oil inside the pulsation hole channel.

Valves having a sprung gate of various constructions are disclosed. In one embodiment, the sprung gate includes a first endless elastic band having an inner perimeter defining an open space sandwiched between a first gate member and a second gate member that each define an opening therethrough in an open position portion thereof. The first endless elastic band is sandwiched therebetween with its open space oriented for alignment with the opening in both of the first and second gate members, which are aligned with one another to form a passage through the sprung gate. In one aspect, the first endless elastic band in positioned inward a distance from the outer sides of the first and second gate members and spaces the first gate member a distance apart from the second gate member thereby defining a channel having a bottom defined by the first endless elastic band.

An engine system having a flowpath between a junction upstream of a turbocharger and an intake manifold that includes an ejector and an aspirator connected in parallel relative to one another within the flowpath is disclosed. The motive flow through the ejector is in the opposite direction relative to the direction of the motive flow through the aspirator, and both the ejector and the aspirator have a suction port fluidly coupled to a device requiring vacuum. The engine system also includes a first check valve disposed in control of the motive flow through the ejector and a second check valve disposed in control of the motive flow through the aspirator and may also include a control valve in fluid communication within the flowpath upstream or downstream of the ejector and the aspirator that controls the flow into and/or out of both thereof.
