    Abstract: A filter system extracts particles and/or drops of liquid from air flowing through the filter system. The filter system has a filter layer disposed in a plane and a cyclone collector that is disposed in the edge region of the filter layer. The cyclone collector is provided with a device which, compared with the filter layer, creates a higher flow speed and stronger vortexing of the circulating air. The cyclone collector can be produced from horizontal cyclone elements, curved, horizontal elements or from expanded metal.

  • Publication number: 20050022483
    Abstract: Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator. The powder falls into a transfer pan and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver. The powder is then discharged to the feed hopper in the feed center. The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line cleaned by one or more cleaning elements drawn through the vacuum line.

  • Publication number: 20050022503
    Abstract: An exhaust gas cleaning apparatus for an engine has a NOx trapping catalytic converter and a control unit for controlling an intake air throttle valve and a fuel injection timing in accordance with an operating condition of the engine. The opening degree of the intake air throttle valve is reduced to accomplish rich spike control. The fuel injection timing is adjusted according to the boost pressure that develops downstream of the intake air throttle valve during rich spike control. Since the combustion tends to degrade when the boost pressure changes during rich spike control, the fuel injection timing is advanced more as the boost pressure becomes larger. This advancement of the injection timing compensates for the combustion degradation and prevents the occurrence of torque fluctuations when the opening degree of the throttle valve is adjusted during the shift to rich spike control to improve the engine operating performance.

    Abstract: When rich spike control is executed in a diesel engine equipped with a NOx trapping catalytic converter, there are times when the amount of NOx desorbed is too little or too much. The rich spike control start timing is determined based on the NOx accumulation amount calculated during lean combustion operation and the rich spike control end timing is determined based on the NOx accumulation amount and the NOx desorption rate. Since the actual amount of NOx remaining in the NOx trapping catalytic converter can be estimated based on the NOx desorption rate during rich spike control, the rich spike control can be ended when the amount of remaining NOx reaches a prescribed target value.

A sub-feedback operation is performed so that the output of the sub-oxygen sensor is fed back and reflected in the fuel injection quantity until the air-fuel ratio of an exhaust gas flowing out of the catalyst agrees with a theoretical air-fuel ratio. Since a catalyst window varies in accordance with the intake air quantity, the fuel injection quantity is corrected so that the larger the intake air quantity becomes, the richer the control A/F is.

    Abstract: An engine fuel injection control apparatus is configured to alleviate the torque fluctuation that occurs due to deviation of the fuel injection timing from the optimum value when the excess air ratio is changed suddenly from lean to rich, such as when a NOx trapping catalytic converter is subjected to desorption and deoxidation treatment. When the excess air ratio changes by a large amount, the fuel injection timing is adjusted so as to change in accordance with the actual excess air ratio by executing an interpolation calculation based on the target excess air ratio and the actual excess air ratio. During the transient period when the actual excess air ratio is converging toward the target excess air ratio, the fuel injection timing is changed in accordance with the change in the actual excess air ratio and can therefore be set appropriately in relation to the actual excess air ratio.

The exhaust gas cleaning system is configured and arranged to determine an accumulation state of particulate matter in a particulate filter by obtaining a reference equivalent surface area of a passage inside the particulate filter based on a pressure difference between before and after the particulate filter, an exhaust gas flow rate, and a temperature of the exhaust gas passing through the particulate filter. The exhaust gas cleaning system is configured and arranged to obtain an adjusted equivalent surface area by adjusting the reference equivalent surface area based on a temperature of the particulate filter and the exhaust gas flow rate. Thus, an amount of particulate matter accumulated in a particulate filter of a diesel engine is accurately estimated without the estimation result being erroneously affected by the engine operating conditions.

    Abstract: An exhaust gas cleaning system is provided that comprises a particulate filter and an NOx trapping catalytic converter disposed upstream of the particulate filter. The exhaust gas cleaning system is configured to determine a combustion amount of the particulate matter accumulated in the particulate filter that are combusted by the NOx in the exhaust gas, and adjust the combustion amount of the particulate matter based on an NOx adsorption condition of the NOx trapping catalytic converter. Then, the exhaust gas cleaning system is configured to estimate a particulate matter accumulation amount in the particulate filter by subtracting the adjusted combustion amount of the particulate matter from a discharge amount of the particulate matter. Thus, the amount of particulate matter accumulated in the particulate filter is estimated more accurately by taking into consideration the combustion of particulate matter by NOx in the exhaust gas.

    Abstract: An internal combustion engine exhaust cooling and removal apparatus includes a heat exchange assembly connected to an exhaust pipe of an internal combustion engine. A flexible hose is connected to the heat exchange assembly, and an exhaust fan assembly is connected to the flexible hose. Use of the internal combustion engine exhaust cooling and removal apparatus of the invention provides a clean air environment in an indoor confined space by removing the engine exhaust gases which are hazardous to one's health. The apparatus of the invention is especially useful with non-electric powered tools and machines, such as for indoor excavations with diesel-powered excavators or other construction equipment. The apparatus of the invention can also be used with diesel-powered saws.

  • Publication number: 20050022522
    Abstract: The invention concerns a hydraulic steering arrangement with a steering motor, a supply path between a pressure source and the steering motor, in which supply path a throttling device and a measuring motor are located, a return path between the steering motor and a pressure sink, in which return path a return throttle is located, and a bypass path, which connects the supply path and the return path on the pressure source end or the pressure sink end, respectively, and which has a bypass throttle. It is endeavoured to make such steering arrangements suitable for fast motorboats. For this purpose it is ensured that with a load on the steering motor the pressure drop over the bypass throttle is larger than the sum of the pressure drops between a point before the first throttle and a point after the last throttle of the throttling device.

    Abstract: An actuator comprises a pump-driving section which is driven and rotated by a current, and a pump mechanism which is connected to the pump-driving section and which sucks/discharges a pressure oil. A cylinder mechanism, which has a piston that is displaceable in the axial direction by being supplied with the pressure oil, is provided on the pump-driving section and the pump mechanism. The amount of discharge of the pressure oil to the cylinder mechanism is adjusted by freely changing the angle of inclination of a tilting member provided in the pump mechanism.
