    Abstract: An air intake housing and flow enhancing plate for a carburetor with a fluted and contoured air intake opening that flushly aligns with and matches the shape of the carburetor air intake opening. The low profile plate is made of metal for durability and heat resistance. The centrally located air intake opening of the plate has a clover leaf or undulating shape that conforms to the shape of the carburetor air intake opening. The plate is secured directly over the top of the carburetor, and extends radially outward to provide a larger area for securing its fiberglass housing. The housing holds a conventional ring shaped air filter located around the carburetor air intake opening. The plate provides smooth transitions between surfaces to decrease turbulence and improve air flow.

  • Patent number: 8541972
    Abstract: Disclosed is a method for suppressing a speed ripple occurring during an operation of an AC motor by using a torque compensator based on an activation function. The method includes the steps of calculating a speed error ?err based on a reference speed ?ref and an actual speed ?act; calculating a controller output Trm by using the speed error ?err as an input of a PI control and an operation of a compensated torque Tcom; and determining a torque variation based on the controller output Trm and a reference torque Tref and operating the torque variation in relation to an anti-windup gain Ka to use torque variation as an input of an integral (I) control. The method suppresses the speed ripple by compensating for the torque ripple through a controller which calculates the compensated torque by taking the signs of the speed error and the differential speed error into consideration.
