An air intake system for a vehicle comprises an exterior air inlet disposed on the vehicle that receives air from an exterior of the vehicle. An air outlet is disposed on the vehicle that supplies air to an engine of the vehicle. A conduit network connects the exterior air inlet and the air outlet. An interior air device disposed on the vehicle is connected to the conduit network allowing air from an interior of the vehicle into the engine. A base plate with an opening is attached to the conduit network. A hatch connected the base plate allows air from the interior of the vehicle through the opening.

An air filter system for a motor vehicle includes a common housing, first and second D-shaped filter elements and a common cover. The common housing defines a first airflow chamber extending between a first inlet duct and a first outlet duct and a second airflow chamber extending between a second inlet duct and a second outlet duct. The first airflow chamber is fluidly separated from the second airflow chamber. The first D-shaped filter element is disposed in the first airflow chamber for filtering air passing through the first airflow chamber. The second D-shaped filter element is disposed in the second airflow chamber for filtering air passing through the second airflow chamber. The common cover is secured to the housing and closes the first airflow chamber and the second airflow chamber.

An intake assembly for an internal-combustion engine includes an intake duct for each cylinder, which communicates with an airbox that includes a filtering element. Each intake duct communicates with the airbox by a respective throttle body. A monitoring channel connects the intake ducts together and is configured for perturbing in a negligible way the dynamics of the fluid inside the intake ducts. Associated to said monitoring duct are sensors for monitoring the pressure inside the monitoring duct and designed to send signals indicating the value of pressure of the fluid taken in by the engine to an electronic control unit.

A filter element having a longitudinal center axis for a fresh air system of an internal combustion engine may include a first plate filter body composed of a pleated filter material and a separate second plate filter body composed of a pleated filter material. The filter element may include first wall body and a second wall body, and a first end body and a second end body. The first wall body, the second wall body, the first end body and the second end body may be connected to the first plate body and the second plate filter body to define an inner space. At least one of the first plate filter body and the second plate filter body may include a curvature projecting to the interior space in a profile extending transversely to a longitudinal direction with respect to the longitudinal center axis.

A filter assembly includes a housing, a cover, and a filter element. The housing defines a pocket. The cover includes a bayonet sized to be received within the pocket. The bayonet defines an elongated opening. The filter element is sized to be received within the housing. The filter element includes a media pack and a filter shell coupled to the media pack. The filter shell includes a trunnion that is sized to be received within both the pocket and the elongated opening to interlock the cover and the filter element such that removal of the cover from the housing initiates removal of the filter element.

An improved internal combustion engine air intake system that operates in tandem with the original equipment air intake system and does not endanger the vehicle warranty and provides improved airflow to the engine which improves engine performance and efficiency. The improved internal combustion engine air intake system also provides one or more additional air inputs taken from a different location than the original equipment air intake which improves the likelihood of providing additional cooler, denser, air to the engine air intake which will improve engine efficiency.

As engines are developing more specific power than earlier versions, the engines move more severely in the engine compartment during torque changes than prior engines. A more robust system to retain engine ducts and tubes is desired, particularly for situations where one end of the duct is mounted to a sub-component in the engine compartment and another end to the engine. A bracketing system for a powerplant for a vehicle has an engine mounted to a vehicle frame via engine mounts, an air cleaner mounted to the vehicle frame, a duct fluidly coupling the air cleaner with the engine, a first bracket coupled to and wrapped around a portion of an engine component, and a second bracket coupled to the first bracket. The first bracket has an orifice for the tie straps to secure the engine coolant tubes and the second bracket is curved to accept the duct.

An air duct for an air induction system of a combustion engine. The air duct includes an air duct, a frame and a hydrocarbon adsorbing member. The air duct housing including a first end and a second end. A fluid path extends between the first and second ends. The frame is disposed in the fluid path. The hydrocarbon adsorbing member is generally planar and is retained within the frame such that first and second opposing planar sides of the hydrocarbon adsorbing member are exposed to the fluid path. The housing may include a first portion carrying the frame. The hydrocarbon adsorbing element may be retained within the frame by a second portion of the housing.

A method for operating an oxycombustion engine system includes passing a nitrogen-depleted gas, a fuel, and a recycled exhaust gas into a combustion chamber, combusting a mixture of the nitrogen-depleted gas, the fuel, and the recycled exhaust gas, thereby producing an exhaust gas including carbon dioxide, detecting a pressure of the recycled exhaust gas passed to the combustion chamber, determining whether the detected pressure of the recycled exhaust gas is less than a configurable pressure threshold, and in response to determining that the detected pressure of the recycled exhaust gas is less than the configurable pressure threshold, increasing the pressure of the recycled exhaust gas passed to the combustion chamber.

A drive torque control device of a vehicle that includes a drive source for generating a drive source torque, a brake mechanism for generating a braking toque, and a drive wheel for driving the vehicle. The drive torque control device includes a target drive wheel torque calculator configured to calculate a target drive wheel torque, a drive source torque control unit configured to estimate a drive source torque limit value, calculate a target drive source torque based on the target drive wheel torque and the drive source torque limit value, and control the generation of the drive source torque by the drive source based on the target drive source torque, and a braking torque control unit configured to calculate a target braking torque based on the target drive wheel torque and the target drive source torque, and control the generation of the braking torque by the brake mechanism based on the target braking torque.
