Abstract: Foldable building units are provided based on structural frame and connection assembly designs that enable greater construction efficiency and flexibility. The structural frame and connection assembly designs allow for easier connection of frame elements in the prefabrication process of the foldable building units and for easier connection of frame elements at the building site, for example, of foldably connected frame elements after unfolding. They also allow for more finish in the prefabrication process, and/or less and faster work at the building site, for example, by enabling conventional structural lumber grids that can be continuous through the edges and corners of the building envelope for conventional exterior finishing, while providing a tight building envelope with reduced heat transfer, particularly, through the edges of the foldable building unit.

The structural frame and connection assembly designs allow for easier connection of frame elements in the prefabrication process of the foldable building units and for easier connection of frame elements at the building site, for example, of foldably connected frame elements after unfolding. They also allow for more finish in the pre-fabrication process, and/or less and faster work at the building site, for example, by enabling conventional structural lumber grids that can be continuous through the edges and corners of the building envelope for conventional exterior finishing, while providing a tight building envelope with reduced heat transfer, particularly, through the edges of the foldable building unit.

Abstract: The present invention is a fuel injection system for small engines in which the fuel injection system takes the place of traditional carburetors and provides the engine with air, fuel and spark control. The fuel injection system is comprised of an electronic control unit (ECU) coupled with a throttle body, which has an integrated fuel injector. The ECU controls the amount of air that enters a cylinder by controlling the throttle plate, and the ECU controls the amount of fuel entering the air flow by controlling the injector. This fuel injection system offers to smaller engines the many advantages of fuel injected engines over carbureted engines such as increased fuel economy, better cold starting capabilities, lower outputs of harmful emissions and lower engine operating temperatures.
