Abstract: An electronic fuel injection system for a cetane number rating system includes a fuel reservoir, a supply line, a drain line, an electrically-controlled fuel valve configured to selectively provide or inhibit fluid communication between the fuel reservoir and the supply line, an electrically-controlled drain valve configured to selectively provide or inhibit fluid communication between the fuel reservoir and the drain line, a low-pressure pump in fluid communication with the supply line, a high-pressure pump in fluid communication with an outlet of the low-pressure pump, and an electronic fuel injector in fluid communication with an outlet of the high-pressure pump. The high-pressure pump is configured to supply pressurized fuel from the fuel reservoir to the electronic fuel injector at a constant flow rate.

Abstract: A seat assembly constructed according to the present invention provides a seat assembly having a cover that is quickly and easily connected to the seat base. The tool and fastener free connection of the seat cover with the seat base provides for a convenient, repeatable, and secure connection of the seat cover with the seat base. A seat assembly constructed according to the present invention also provides for the convenient and expeditious connection of a plurality of seat assembly elements. The fastener free connection between the multiple components of the seat assembly provides for the economical manufacture and assembly of the seat assembly. Such a construction provides a multi-piece seat assembly wherein the components of the seat assembly can be connected without fasteners and without tools.
