  • Patent number: 11225932
    Abstract: An apparatus and method are provided for a fuel bowl to supply liquid fuel to a carburetor. The fuel bowl comprises a float chamber and a fuel inlet cavity which receives a fuel delivery insert. The fuel delivery insert receives a fuel inlet valve and comprises passages to direct incoming fuel to a bottom portion of the float chamber. A float comprises an elongate member rotatably hinged within a float cavity of the fuel delivery insert, such that the float rises according to a quantity of fuel within the float chamber. The fuel inlet valve supplies liquid fuel to the float chamber by way of the passages according to the operation of the float within the float chamber. A ventilation chamber allows air and fuel vapors to exit as liquid fuel enters the float chamber while preventing liquid fuel from entering into the carburetor.

  • Publication number: 20220001640
    Abstract: A pleated filter preparation system is provided for accurately counting pleats along a continuous sheet of pleated filter material and cutting the sheet into filter strips to be formed into filters. The pleated filter preparation system includes a pleat driver having multiple drive gears that engage with the pleats of the pleated filter material to move the pleated filter material through the system. A pleat counter counts peaks and valleys of each pleat comprising the pleated filter material so as to identify a target pleat to be cut. The pleat counter clamps and stretches the target pleat to distinguish the target pleat among the other pleats. A punch cut station cuts the target pleat to form a filter strip having a desired number of pleats. A pleat compressor compresses the filter strips to a predetermined size and then ejects the filter strips into a suitable container or bin.

  • Patent number: 11181055
    Abstract: A throttle-controlled intake system is disclosed that provides a driver of a vehicle with greater control over engine functions and vehicle performance. The throttle-controlled intake system includes a control module that is coupled with an aircharger air intake. The control module processes input signals from a throttle pedal of the vehicle and sends modified throttle position signals to a throttle body of the vehicle so as to increase throttle responsiveness of the vehicle. The throttle-controlled intake system further includes a wiring harness and a signal adjuster. The wiring harness electrically couples the control module with the throttle pedal and the throttle body. The control module sends signals directly to the throttle body of the engine, bypassing an electronic control unit of the vehicle. The signal adjuster includes a rheostat that enables manual adjustment of the throttle responsiveness of the vehicle.

  • Publication number: 20210340941
    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.
