4445488 Exhaust gas recirculation control for diesel engine
New Patents
steam mixture is returned from the steam generating bank (20, 48) to the steam drum (14, 42) and is directed into the centrifugal water separator (16, 44) that is suitably located within the steam drum (14, 42). It is in the centrifugal water separator (16, 44) that the separation of the water-steam mixture is effected such that water is returned to the lower portion of the steam drum (14, 42) and the steam is supplied to the upper portion of the steam drum (14, 42). The preheating of the feedwater is accomplished by directing the incoming feedwater through an internal feed pipe (66) to the mixing nozzle (50), the latter being positioned in the line (60) through which the water-steam mixture is returned to the steam drum (14, 42).

In an apparatus for controlling the EGR in a diesel engine, a single pressure control valve adjusts the control pressure from a pump automatically when the pressure changes, and supplies the control pressure in response to the command signal of a control circuit to an EGR valve and a waste-gate valve of a turbocharger. The pressure control valve includes an electric actuator, a spool valve, a sleeve, a diaphragm, and a spring. By using this apparatus, a diesel engine which has a high response speed, high control precision, simple constitution, less nitrogen oxides in the exhaust gas, and low manufacturing cost is obtained. 4445910

A gas generating system deriving useful BTU products from cellulosic waste material and comprising a conical shell to which the waste material is fed at the bottom and moved upwardly by an auger to permit the expanding walls of the cone to loosen the material by sintering action in the upper portion of the shell in a combustion zone located above the level of a row of air inlet ports substantially midway of the shell, the shell also having a gas accumulating chamber in the top thereof and a gas discharge device leading from the chamber to gas purifying and cooling mechanism including spray devices, a settling tank and liquid storage tank operating in a manner to re-use liquid incident to the operation of the spray devices. Operation of the controlled air delivery to the nozzles and cone also can be regulated to produce desirable amounts of charcoal and mechanism is included to remove the same from the cone.
