摘要： The present invention relates to an enzymatically modified dietary fiber material particularly a soy fiber material of improved sensory properties including smoothness and mouthfeel characteristics. The modified fiber is formed by forming an aqueous slurry of a soy dietary fiber material and modifying or hydrolyzing the material with a process modifying dietary soy fiber and the resulting enzyme mixture which comprises a mixture of a cellulase and a carbohydrase. The degree of hydrolysis is sufficient to improve the sensory properties of the soy fiber material without substantially reducing the dietary fiber content thereof.

摘要： An exhaust system for an internal combustion engine having a primary catalytic converter located downstream of the engine and a hydrocarbon adsorber located downstream of the primary converter. The adsorber comprises a ceramic wall-flow substrate having a zeolite coating, having the ability to selectively adsorb hydrocarbon molecules from exhaust gas, applied to the interior surfaces of the inlet passages of the substrate and a catalytic coating applied to the adjacent surfaces of the walls of the outlet passages of the substrate. The catalyst preferably has a light-off temperature below the desorption temperature of the zeolite. In operation, hydrocarbon is adsorbed by the zeolite following a cold engine start and is held until the zeolite reaches its desorption temperature at which time the hydrocarbon is released and passes through the porous walled substrate for conversion by the catalyst.

摘要： An air/fuel ratio controller for an internal combustion engine including a memory having numbers stored at locations addressed by engine operating points with the locations addressed by the engine operating points being updated during closed loop operation in accord with the value of a closed loop adjustment of the air/fuel ratio. Each memory location in the memory is updated during operation of the engine at the corresponding operating point in accord with an update time constant having a value so that the number stored tracks adjustment value producing the predetermined desired closed loop air/fuel ratio during varying values of engine temperature. The update time constant is varied directly with the value of engine temperature so that the rate of adjustment of the numbers in the memory is greater during engine warmup where engine temperature increases rapidly. The memory is used during closed loop operation to preset the closed loop adjustment at least when the engine first operates at an operating point.
