A metering system for a fuel atomizer includes a housing having a fuel inlet and an oxidizer inlet arranged coaxially, and an oxidizer metering device having a plurality of oxidizer channels, an oxidizer flow controller, and a fuel metering device. The oxidizer channels are spaced apart circumferentially in the housing and are arranged angled in at least one of a radially inward direction and a tangential direction to create a swirl of oxidizer flow in a mixing chamber of the fuel atomizer. The oxidizer flow controller is configured to control flow of oxidizer from the oxidizer inlet to the plurality of oxidizer channels. The fuel metering device is configured to control fuel flow from the fuel inlet to the mixing chamber.

Co-axial dual fluids metering system and methods

A metering system for a fluid atomizer includes a housing, first and second metering members, and at least one solenoid. The housing includes a mixing chamber. The first metering member is operable to control flow of a first fluid to the mixing chamber. The second metering member is arranged coaxial with the first metering member and operable to control flow of a second fluid to the mixing chamber. The at least one solenoid is configured to operate at least one of the first and second metering members.

Riding lawn mowers may utilize friction drives configured with a variable normal force between frictional components. In a riding lawn mower, an internal combustion engine may be coupled to a differential via a friction drive, wherein the friction drive is configured with a variable normal force in order to provide improved power transfer and/or shifting performance.

A lawn mower has a dual-tubular frame for shock absorption. The dual-tubular frame has two parallel, longitudinally-extending tubular structures with curved portions allowing for flexion. A seat bracket interconnects the tubular structures. An engine is mounted to the tubular structures rearward of the seat bracket.

A metering system for a fuel atomizer includes a housing, first and second metering members, and at least one solenoid. The housing includes a mixing chamber. The first metering member is operable to control flow of oxidizer to the mixing chamber. The second metering member is arranged coaxial with the first metering member and operable to control flow of fuel to the mixing chamber. The at least one solenoid is configured to operate at least one of the first and second metering members.

An air charging system includes a valve providing access to an engine cylinder, an accumulator coupled in flow communication with the valve, and a controller operable to open and close the valve until a threshold pressure condition is reached in the accumulator. Compressed gases stored in the accumulator are used in a fuel delivery system to prepare a charge of fuel that is delivered to an engine.

In-cylinder charging system for fuel delivery systems and methods

A riding lawn mower may include a cutting deck coupled to a cutting blade, an engine, a deck drive coupled to the engine to receive power for operating the cutting blade, a ground drive coupled to the engine to receive power for movement of the riding lawn mower over ground, and a friction drive coupling the deck drive to the engine.
