  • Patent number: 10837352
    Abstract: Apparatus and method for directing airflow into the air intake (carburetor or fuel injection system) of an internal combustion engine for increasing air flow velocity and the quantity of air reaching the cylinder or cylinders thereof through the use of an electrically powered fan, are described. The fan is installed inside of the air filter element such that when the air intake throttle plates are closed or partially closed, the unused airflow exits the apparatus to relieve the pressure created by the fan, and when additional air is needed by the engine, air can enter the filter element. The fan may be continuously operated during the operation of the motor, and at all engine speeds.

  • Patent number: 10092869
    Abstract: A separator (1) for separating contaminants from a fluid stream having entrained particulate contaminants, comprises a cylindrical dividing wall (28) concentrically arranged within an impaction surface (35). The cylindrical dividing wall defines a first chamber (42) into which a fluid stream enters and flows axially through. The dividing wall has apertures (29) through which the fluid stream passes towards the impaction surface. As the fluid impacts the impaction surface, the contaminants are separated from the fluid and flow down to an oil outlet (23). A diaphragm (31) moves along an axis to adjust the open cross-sectional area of the apertures in the dividing wall according to a pressure differential between fluid pressure in the first chamber and a pressure reference by moving along the dividing wall to progressively occlude the apertures. The apertures are spaced so that there is no overlap between them along the actuator axis.

    Abstract: An exhaust gas plume mitigation process and system includes either mixing secondary heat into a moisture rich exhaust gas stream, or diverting a moisture rich exhaust gas stream into a primary exhaust stack having hot exhaust gases flowing therethrough. Moisture rich exhaust gas from a liquid concentrator may be diverted into a high temperature exhaust stack of an engine, a generator, or a flare. The high temperature exhaust gases from the engine, the generator, or the flare raise the temperature of the moisture rich exhaust gas from the concentrator. The high temperature exhaust gases from the engine, the generator, or the flare are also lower in moisture content, so that the moisture rich exhaust gas from the concentrator is diluted by the drier high temperature exhaust gas. As a result, the mixed gas is less likely to develop a moisture plume upon exit to the atmosphere.

The baffle includes a hook-shaped portion, in which the oil segregation takes place. The engine crankcase breather further includes a trough extending within the housing. The trough is aligned with the hook-shaped portion of the baffle, to collect the segregated oil from the blow-by gases.

  • Patent number: 8585800
    Abstract: An apparatus is configured for filtering a cooling duct of a battery for an electric vehicle. More specifically, a dust sensor is installed in the cooling duct through which cooling air is introduced into the battery for the vehicle and a variable filter is installed in the cooling duct to filter the cooling air and open/close the cooling duct via a driving unit. A control unit configured to control the driving unit according to a signal or sensing value from the dust sensor and a measured temperature of the battery. In particular, when dust is not detected, the cooling duct is fully opened by folding the variable filter. If, however, dust is detected an opening degree of the variable filter is adjusted to close or at least partially close the cooling duct according to the temperature of the battery.

  • Patent number: 8539755
    Abstract: Particles smaller than 50 nanometers emitted from an internal combustion engine, and serving as nuclei for forming PM (particulate matter), are removed to decrease the number of PM particles that are emitted to atmosphere. High efficiency filters are provided in passages that feed fluids into the combustion chamber, e.g., intake air, fuel and engine oil, in order to remove particles smaller than 50 nanometers serving as nuclei for forming PM.

  • Patent number: 8535401
    Abstract: The present invention relates to an air cleaner for the removal of pollutants from an air flow by a filter module, the filter module of which includes at least one permeable filter layer for the accumulation of pollutants on the filter layer. According to the invention, a bypass channel will be provided and established such that part of the unfiltered air flow may bypass any filter layer. Surprisingly, such a bypass channel does hardly compromise the cleaning effect of the filter module, at least as long as the filter layer has not yet been clogged with pollutants since in this case the biggest part of the air flow will take the major path through the filter layer due to lack of resistance. Only if the filter layer is clogged and if resistance for the air flow increases, air will obviously flow through the mentioned bypass channel.

  • Patent number: 8454716
    Abstract: A particle separating structure for use with a turbine engine. The particle separating structure includes a main housing, first swirling structure, and second swirling structure. The first swirling structure is provided for swirling cooling fluid passing through a first cooling fluid flowpath defined in the main housing. The second swirling structure is provided for swirling cooling fluid passing through a second cooling fluid flowpath defined in the main housing. The first swirling structure is positionable in at least two positions, a first position allowing cooling fluid to pass through the first cooling fluid flowpath and a second position allowing cooling fluid to pass through the first and second cooling fluid flowpaths. The swirling of the cooling fluid causes particles in the cooling fluid to pass to a particle discharge zone while the cooling fluid passes out of the main housing through a cooling fluid outlet.

    Abstract: A filter cassette and a method for allowing a leak to be detected are disclosed, in which the filter cassette comprises a main body defining a first chamber. The main body includes an inlet and an outlet, a filter separating the first chamber into first and second sub-chambers, the inlet being in fluid communication with the first sub-chamber and the second sub-chamber being in fluid communication with the outlet. The main body also includes a second chamber is defined by the main body and the filter, wherein in absence of a leak the second chamber is substantially not in fluid communication with the first chamber. The main body further includes a port in fluid communication with the second chamber, whereby measuring a fluid characteristic in the second chamber by means of the port allows a detection of a leak, i.e. an external leak or a bypass leakage.

  • Publication number: 20120260615
    Abstract: The present invention relates to a coupling head for coupling a towing vehicle to a trailer. According to the invention, in the coupling head a filter element is used. The filter element is bypassed by a continuously open by-pass. Preferably, the path through the by-pass has at least one redirection in the region of an undercut. As a result of the redirection, contaminants in the compressed air are not or not fully transferred through the by-pass. The by-pass might also ensure a supply of compressed air to the trailer, for example, when the filter element is at least partly blocked due to the contaminants. According to the invention, a valve element used to open the by-pass in the case of increasing blockage of the filter element is not required.
