Abstract: A combined mass airflow sensor and hydrocarbon trap is provided for absorbing evaporative hydrocarbon emissions from an air intake duct of an internal combustion engine. The combined mass airflow sensor and hydrocarbon trap comprises a duct that supports a hydrocarbon absorbing sheet in an unfolded configuration within a housing. The duct communicates an airstream from an air filter to the air intake duct during operation of the internal combustion engine. An opening in the housing receives a mass airflow sensor into the duct, such that the mass airflow sensor is disposed within the airstream. Guide vanes extending across the duct reduce air turbulence within the airstream passing by the mass airflow sensor. Ports disposed along the duct allow the evaporative hydrocarbon emissions to be drawn into the interior and arrested by the hydrocarbon absorbing sheet when the internal combustion engine is not operating.

Abstract: A system and methods for a turbo-boost control system are disclosed for providing a driver of a vehicle with greater control over vehicle performance. The turbo-boost control system instructs an electronic control unit of the vehicle to increase the manifold pressure to a higher level before releasing the pressure through a waste gate so as to provide a greater power output of the engine. The turbo-boost control system includes a control module, a wiring harness, and a signal adjuster. The wiring harness couples the control module with a turbo inlet pressure sensor, a manifold absolute pressure sensor, and an electronic control unit of the vehicle. The control module sends signals to the electronic control unit based on input readings from the turbo inlet pressure sensor and the manifold absolute pressure sensor. The signal adjuster includes a rheostat that enables manual adjustment of the power output of the engine.

Abstract: An apparatus and methods are provided for a throttle body spacer that improves the performance of an internal combustion engine. The throttle body spacer comprises a body that includes an airflow opening for conducting airflow from a throttle body into an intake manifold. A spiral is disposed along a sidewall of the airflow opening and configured for swirling the airflow. The spiral comprises a helical shape disposed around a circumference of the sidewall and extends from an initial bore near a first contact surface of the body to a second contact surface. The helical shape includes a diameter that increases as the spiral extends toward the second contact surface, giving the body a sidewall taper angle that contributes to an increase in power output of the engine. A sawtooth cross-sectional shape of the spiral causes the airflow to swirl so as to improve atomization of an air-fuel mixture entering engine.

Abstract: An apparatus and a method are provided for a heating, ventilation, and air conditioning (HVAC) home air filter to remove airborne molecular contaminants and volatile organic compounds (VOCs) from air within residential spaces. The HVAC home air filter a supportive frame having a shape and size suitable to orient the HVAC home air filter within a residential HVAC system. A filter medium is retained within the supportive frame to remove the airborne molecular contaminants and VOCs from air flowing through the residential HVAC system. The filter medium is a combination of media layers configured to exhibit a relatively high filtration efficiency and a low air pressure drop across the filter medium. The supportive frame comprises a plurality of elongate sections and corner sections disposed along perimeter edges of the filter medium to support the filter medium within the residential HVAC system so as direct air through the filter medium.

Abstract: An apparatus and method are provided for a flangeless air filter configured to be mounted onto a flat surface within an air intake system of an internal combustion engine. The flangeless air filter is comprised of a cone-shaped filter medium, retained between a base and a cap, that is fabricated to remove contaminants and particulate matter from an intake airstream. The base includes a pliable seal that forms an airtight connection between the flangeless air filter and the flat surface of the air intake system. A mounting bracket and fasteners may be used to attach the base to the flat surface, compressing the seal there between. In some embodiments, the mounting bracket may be incorporated into, and made a part of the base. A cap is disposed on a top of the flangeless air filter and configured to direct the intake airstream around the cap and toward the filter medium.

Abstract: An apparatus and methods are provided for a sound effect generation system for broadcasting engine sounds outside a vehicle. The sound effect generation system enables a driver to select and manipulate the sounds emitted outside the vehicle. The sound effect generation system includes a wireless sound generator module for simulating engine sounds, a speaker for broadcasting the engine sounds outside the vehicle, and an external GPS antenna for measuring a speed of the vehicle. When the vehicle is turned on and remains stationary, the sound generator module simulates an idling internal combustion engine. When the speed of the vehicle increases, revving of the internal combustion engine and transmission shifting are simulated. When the speed of the vehicle decreases, a decelerating internal combustion engine is simulated. The sound effect generation system includes settings that may be accessed by a wireless mobile device whereby the driver can manipulate the engine sounds.
