ActiveUS7640766B2Good responseIncrease flow rateWater treatment parameter controlDomestic cooling apparatusStreamflowOzone generators
A method and apparatus for providing sanitized water in a cabinet and spigot type bottled water dispenser features an ozone generating system to generate ozone for sanitizing the water. Ozone is generated and collected within an ozone generator housing. A blower transmits air to the ozone generator housing. The air carries the ozone that is generated through a flow line to an air diffuser that is positioned upstream of the spigot (or spigots) used to dispense water. In one embodiment, a valve that is activated on the spigot to dispense water also activates the blower and ozone generator. In other embodiments, a flow sensor activates the ozone generator and blower. Various spigot and flow sensor arrangements are disclosed as a part of the overall apparatus and method.

An air fuel ratio control apparatus for an internal combustion engine can achieve control behavior with good stability and response that is appropriate for a delay in an oxygen storage operation of a catalyst, and can always keep the state of purification of the catalyst adequately. The apparatus includes an upstream oxygen sensor (13), a downstream oxygen sensor (15), a first air fuel ratio feedback control section (130) that adjusts an amount of fuel to be supplied so as to make an air fuel ratio in an upstream exhaust gas and an upstream target air fuel ratio (AFobj) coincide with each other, and a second air fuel ratio feedback control section (150) that operates the upstream target air fuel ratio (AFobj) in accordance with an air fuel ratio deviation between an air fuel ratio detected by the downstream oxygen sensor (15) and a downstream target air fuel ratio so as to make the detected air fuel ratio of said downstream oxygen sensor (15) and the downstream target air fuel ratio coincide with each other. The second air fuel ratio feedback control section (150) sets an integral gain of integral calculation to be larger in accordance with an increasing flow rate of the exhaust gas, and also sets a proportional gain of proportional calculation so as not to be changed with respect to a change in the flow rate of the exhaust gas.

In a non-EGR region that is a light load operating region, an EGR control valve (21) is opened at a predetermined infinitesimal opening degree M that corresponds to such infinitesimal EGR ratio as not to affect an ignition timing. With this control, since an EGR passage (20) is basically in a state in which the EGR passage (20) is filled with EGR gas, when an operating condition is changed from the non-EGR region to an EGR region and the EGR control valve (21) is opened so as to gain a target EGR ratio, a desired quantity of the EGR gas is introduced into an intake passage (2) substantially at the same time as the opening of the EGR control valve (21). An actual EGR ratio can thus follow the target EGR ratio with a good response.
