Cylinder cutoff control apparatus of internal combustion engine
InactiveUS20060037578A1Reduced engine braking effectTendency increaseValve arrangementsElectrical controlExhaust valveTop dead center
A cylinder cutoff control apparatus of an engine initiates a cylinder cutoff mode only when two conditions, namely a low load condition such as a vehicle cruising condition and an intake valve closure timing controlled to a given timing value before a bottom dead center, are both satisfied. A fuel cutoff mode is executed prior to the cylinder cutoff mode. During a transition to the cylinder cutoff mode, the control apparatus holds an intake valve open timing at a given timing value substantially corresponding to a top dead center, simultaneously with reducing an intake valve lift amount of each intake valve, subjected to cylinder cutoff control, to a zero lift. Immediately when the intake valve lift amount is reduced to below a lift threshold value, an exhaust valve lift amount of each exhaust valve, subjected to the cylinder cutoff control, is controlled to a zero lift.

An online virtual reality ecommerce system imposes needs upon its avatars, thereby enhancing the simulation of reality, and providing need-based motivations for ecommerce in addition to enjoyment-based motivations. The virtual needs also cause avatars to be perceived as independent beings which can independently enjoy, desire, and suffer based on experiences and purchases within the virtual world. This causes users to emotionally bond with their avatars, and to feel compassion, empathy, and even friendship toward them. Users feel increased desires to spend time online with their avatars, and to purchase goods for their avatars as well as for themselves. Avatars can be fantasy avatars in a virtual fantasy world, and their needs can include special, fantasy items. Basic needs can include food, clothing, shelter, exercise, bathing, shaving, medicine, and haircuts. Entertainment can be needed to avoid boredom, and specific tools, equipment, fuel, and / or transportation can be needed for various activities.

The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate titania. It has been discovered that the nature of the surfaces of the nanoparticles used to support a nano-metal catalyst, such as catalytically active gold, has a profound effect upon the catalytic properties of the supported catalyst. The support surface may be altered as desired to control the activity of the gold. The present invention teaches how thermal treatment of nanoparticulate media incorporated into a nanoporous support prior to deposition of catalytically active gold dramatically suppresses the ability of a resultant catalyst system to oxidize hydrogen.
