The present description provides low DBL bleed emission performance properties that allows the design of evaporative fuel emission control systems that are simpler and more compact than those possible by prior art by inclusion of a vent-side volume comprising a parallel passage adsorbent such as a carbon honeycomb with narrow channel width and low cell pitch.

An intake device includes an air filter that filters intake air for an internal combustion engine, a filter casing housing the air filter, and an air physical quantity sensor. The filter casing includes an intake passage to allow the intake air to pass from upstream to downstream of the air filter. The filter casing has a passage wall portion that is electrically conductive and exposed to the intake passage on a downstream side of the air filter. The air physical quantity sensor has: a sensor element that detects a specific physical quantity related to the intake air on a downstream side of the air filter; and a grounding structure electrically connected to the passage wall portion for grounding the sensor element.

Apparatus and method for directing airflow into the air intake (carburetor or fuel injection system) of an internal combustion engine for increasing air flow velocity and the quantity of air reaching the cylinder or cylinders thereof through the use of an electrically powered fan, are described. The fan is installed inside of the air filter element such that when the air intake throttle plates are closed or partially closed, the unused airflow exits the apparatus to relieve the pressure created by the fan, and when additional air is needed by the engine, air can enter the filter element. The fan may be continuously operated during the operation of the motor, and at all engine speeds.

A breach detection system for an internal combustion engine having a crankcase, an intake manifold, a positive crankcase ventilation valve, a crankcase ventilation tube with a flow control system therein, and a pressure sensor between the flow control system and the crankcase. The flow control system subdivides the crankcase ventilation tube into a plurality of parallel conduits—a first conduit having a normally closed check valve that opens under a first preselected pressure drop in a first direction from the air intake to the crankcase, and a second conduit having either a second check valve that opens under a second preselected pressure drop in a second direction opposite the first direction or a restriction profile having a third preselected pressure drop that is the same in both the first and second direction. When the pressure sensor detects no pressure drop there is a breach in the system.

An intake system of an engine of a vehicle includes a turbocharger having an elbow configured to be connected to a compressor of the turbocharger. The elbow for the turbocharger includes: an inlet through which a first fluid is introduced; an outlet through which the first fluid is discharged; a passageway part extending between the inlet and the outlet; and a fusion part provided between the inlet and the outlet and configured to communicate with an inside of the passageway part.

Methods and systems are provided for carrying out diagnostics of a bleed canister of an evaporative emissions control system in a vehicle. In one example, a method may include, loading the bleed canister during a refueling event, and then during an immediately subsequent engine start, detecting if the bleed canister is degraded or not based on output of an exhaust gas oxygen sensor.

Methods and systems are provided for adjusting a location of a fuel injection in response to a substitution rate and a desired EGR flow. In one example, a method may include injecting a first fuel to a combustion chamber via a direct injector positioned to inject directly into the combustion chamber, injecting a second, different, fuel to the combustion chamber via an exhaust port injector positioned to inject toward an exhaust valve of the combustion chamber, and combusting the first and second fuels together in the combustion chamber.

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.

An air intake system (100″) for vehicle is provided. The air intake system (100″) includes an air filter assembly (108), and an air conduit (101). The air filter assembly (108) includes a first part mounted to a frame of the vehicle, and a second part mounted to a chassis of the vehicle. The first part and second part are arranged in such a manner that the attachment of the frame and the chassis together causes assembly of the first part and second part of the air filter assembly (108). The air conduit (101) includes an inlet end (103) and an outlet end (105), and coupled to a turbocharger. The air conduit (101) extends horizontally between the inlet end (103) and the outlet end (105) and comprises a plurality of segments such that a first segment bends at predefined angles to couple to a second segment of the plurality of segments.

Vehicle Engine Air Intake System and Method (to be accompanied by FIGS. 1 and 3) In a motor vehicle (12), an air filter housing (14) is at least partially defined by a cross-member (28) forming part of a structural front end module of the vehicle body. The cross-member (28) defines a recess (44) for receiving an air filter (90) and at least one air inlet aperture opening into the recess. An air filter enclosure assembly is mounted to the cross-member over an open face of the recess. The air filter enclosure assembly may include an air filter enclosure (42) and an air filter (90).
