Abstract: The instant invention is directed to a pet shelter for domestic pets. More specifically, the instant invention is a pet shelter constructed from a plurality of plastic panels each having integral connectors. The panels are constructed and arranged to be shipped and/or stored in a nested or stacked arrangement to reduce space requirements and shipping costs. The integral fasteners formed onto the panels intermesh to allow the panels to be snapped together without the need for additional fasteners or tools.

Abstract: Boosted engine operation and spark timing of an engine may be adjusted with alcohol content of the fuel in a direct injection engine. Further, various adjustments may be performed in numerous related systems to account for increased maximum engine torque, such as traction control, transmission shifting, etc.

Abstract: A method of controlling fuel supplied to an engine of a vehicle is provided. The vehicle includes a first fuel storage tank to store a first type of fuel, a second fuel storage tank to store a second type of fuel, and an emissions control device. The engine includes at least one cylinder having a direct injection fuel injector being selectively supplied with the first type of fuel from the first fuel storage tank and the second type of fuel from the second fuel storage tank. The method includes supplying the first type of fuel from the first fuel storage tank to the direct injection fuel injector in response an engine start condition of the vehicle, and supplying the second type of fuel from the second fuel storage tank to the direct injection fuel injector, in response to an increase in engine output exceeding a threshold increase or a temperature of the emissions control device exceeding a threshold temperature.

Abstract: As one embodiment, a method of operating an engine of a vehicle is provided wherein the engine has a variable engine output. The method comprises during a first engine output, delivering a first fuel to at least a cylinder of the engine via a first injector and directly injecting a second fuel directly into said cylinder via a second injector; and during a second engine output lower than said first engine output, delivering said first fuel to said at least a cylinder of the engine via said first injector and directly injecting at least a purging substance via said second injector based on an idle period since a previous injection by said second injector.

Abstract: A system for an engine, comprising of a cylinder located in the engine, a first port injector for injecting a first fuel into said cylinder, and a second injector outside said cylinder for injecting a second fuel into said cylinder.
