A leaf screen for an air intake of an HVAC system of a vehicle having a hood covering an engine compartment. The leaf screen includes a leaf screen body defining an air inlet opening covered by an integrally molded screen. A seal is integrally molded on a top surface of the leaf screen body in front of the air inlet opening. Bump-stops are integrally molded on the top surface that are engaged by an inner panel of the hood when closed. A method of making the leaf screen includes injecting a polymeric material into a mold to form a body portion. At least one elastomeric material is injected into the mold on one side of the body portion to form a seal and a plurality of bump-stops.

A resin cowl grille is provided to cover an upper portion of a cowl box. The cowl grille includes an upper wall portion and a front wall portion separated from the upper wall portion and provided with a bending promotion portion for inducing bending deformation upon action of load from above. The front wall portion includes a body portion and attachment piece portions extending backward from the body portion and fastened to a front portion of the upper wall portion. A weak portion for load in an upper-to-lower direction is formed by the attachment piece portion.

A wind-powered electric vehicle power regeneration system for increasing the range of electric vehicles. The system includes a twin turbine system with at least one fan on each turbine, and may include a vacuum-assisted turbine and gearbox. The twin turbine system preferably has three fans on each turbine. The fans may be of various sizes. The first and largest fan may be directly powered via the electric vehicle motor, which may create a vacuum. The second fan may partially be powered by the EV motor, while also being moved by the vacuums suction and the air that enters the compartment. The third fan may rotate via force of air entering the compartment. All of the fans may be connected to a central gearbox located beneath them. The gearbox may be connected to a generator that may be connected to a capacitor that charges an electric vehicle's battery.

An apparatus and a method are provided for a multiple inlet air box to communicate an airstream through an air filter to an air intake duct of an internal combustion engine of a vehicle. The multiple inlet air box is comprised of a housing that supports the air filter within an interior of the housing. A mount portion within the housing fixedly receives a base of the air filter. Multiple air inlets couple with corresponding air inlet ports of the vehicle to direct the airstream into the multiple inlet air box. A duct directs the airstream from the multiple air inlets to the interior of the housing. A conduit communicates the airstream from an interior of the air filter to the air intake duct of the internal combustion engine.

A connecting pipe is made from polymer material and is shaped to link an opening of an air inlet pipe of a thermal device of a motor vehicle and an opening of a firewall of the vehicle. The connecting pipe has a cross section equal to or greater than a cross section of the air inlet pipe. The connecting pipe has two open ends. The two open ends include a first open end having a first interface which is shaped to be assembled and fixed to the air inlet pipe, and a second open end having a second interface which includes a bearing surface which is shaped to be applied against the firewall on the periphery of the firewall opening.
