A carburetor includes a carburetor bowl, a fuel supply pipe, a fuel drain pipe, and a valve. The carburetor bowl is configured to store fuel and provide the fuel to an air passage. The fuel supply pipe is connected a fuel tank and the carburetor bowl. The fuel drain pipe is connected to the carburetor bowl and the fuel supply line. The valve for the fuel drain pipe is configured to open and close in response to an orientation of the carburetor.

In one example, fleet devices are monitored. The fleet devices include engines. A controller, such as an engine controller or centralized controller, receives sensor data indicative of a load on the engine from one or more of the fleet devices. The controller analyzes the load from the sensor data to identify a management function. The controller generates a message including the management function.

Fleet management system

An apparatus or system includes a component that generates or transfers noise having a frequency within a noise frequency range. The component may include a boundary. The apparatus or system may be an engine in some examples. The engine may additionally include a micro-perforated sheet positioned a distance from the boundary. The micro-perforated sheet may include a plurality of micro-perforated holes, and may be configured to absorb sound within an absorption frequency range based on parameters of the micro-perforated sheet. The parameters may include the distance from the boundary and dimensions of the micro-perforated holes, and may be set such that the absorption frequency range overlaps the noise frequency range.

Noise suppression systems

An apparatus includes a controlled field alternator or utility source of electrical power, a segmented waveform converter, and a controller. The source of electrical power is configured to generate a polyphase signal. The synchronous inverter includes multiple switches connected between the polyphase signal of the source of electrical power and an output filter. The controller is configured to provide a control signal for the switches based on measured electrical quantities associated with the output filter and may provide a field control signal to the controlled field alternator. The apparatus may be applied to a vehicle, a lawnmower, a zero turn radius lawnmower, or another type of machine.

A highly durable engine grass screen assembly is disclosed. The assembly includes a grass screen for covering an air intake port of the engine, a grass screen stiffening mechanism for supporting the grass screen, a washer mechanism for compressing the screen such that the screen is pre-stressed during manufacture and such that the screen remains in compression during engine operation. The assembly can include one or more stud mechanisms which are securable to either an engine flywheel assembly or an engine fan assembly. The washer mechanism, the grass screen and the grass screen stiffening mechanism are engaged in a secured fashion to one or more stud mechanisms. A method of assembling and positioning a grass screen assembly in an engine is also disclosed.
