Abstract: A system and method for reduction of Nitrogen Oxide emissions from marine engines by converting Nitrogen Oxide into Nitrogen is disclosed. The modular reactive cyclic induction apparatus connects to the exhaust of a conventional diesel marine engine and uses air pressure and the sodium chloride in seawater to create a molecular reaction to break down Nitrogen Oxide into Nitrogen by use of an induction apparatus. The system can also include a loop for removing Carbon Dioxide through electrolysis, and removes other environmental pollutants as well, including for example Sulphur oxides, hydrocarbons, and particulate matter during the process.

Abstract: The invention relates to an air cleaner for a vehicle which can be installed on the rear of the vehicle, which includes a suction pipe provided with a slit having a length corresponding to a width of the vehicle, an air pump connected to inside of the suction pipe by a guide pipe, and a filter means connected to the air pump. The air cleaner is operated in a way of sucking exhaust gas and fine dust generated from an exhaust line of the vehicle together with fine dust and dust particles generated around tires of the vehicle during driving of the vehicle, removing them, and then discharging purified air to the atmosphere. The air cleaner can effectively remove the fine dust and various-shaped dust particles directly and indirectly generated from the vehicle, and remarkably reduce generation of fine dust by considerably suppressing diffusion of fine dust into atmosphere.

Abstract: A secondary air system for an aircraft engine comprises an air flow path communicating between a source of pressurized cooling air and an air consuming component. A filter is disposed in the air flow path upstream from the air consuming component. The filter has at least one of: openings of a size selected for capturing suspended particles; and a filter surface material for binding with chemical contaminants.

Abstract: An apparatus for exhaust gas purification comprises a filter function. The apparatus includes a gas-permeable substrate which forms a wall-flow filter that forms channels. The channels are sealed at least at one end and exhaust gas is flowable through the channels and gas-permeable channel walls of the channels formed from the substrate. A surface of the substrate is provided with an oxygen-storing coating. The mass of an oxygen-storing material coated on the surface of the substrate on an outflow side is higher than the mass of the oxygen-storing material coated on the surface of the substrate on an inflow side.

Abstract: A regeneration control device for an exhaust purification device includes a regeneration controller that executes regeneration control in which particulate matters trapped by a filter are removed by combustion, and a post-injection controller that during the regeneration control, executes control in which a time period of a post-injection of fuel executed subsequently to a main injection of fuel is advanced such that a supercharging pressure of a turbosupercharger becomes higher than a supercharging pressure during steady operation.

Abstract: An exhaust gas purification system of a working machine is operable to reduce a loss of a working time caused by a point that it takes a long time to renew an exhaust gas purification device by throttle devices. The exhaust gas purification system of the working machine is provided with a common rail type engine which is mounted to the working machine, an exhaust gas purification device which is arranged in an exhaust system of the engine, and at least one of the intake air throttle device and the exhaust gas throttle device. It is provided with mode selection input means which selects whether an auxiliary renewing mode is executed or a forced renewing mode is executed in the case that a clogged state of the exhaust gas purification device is equal to or more than a prescribed level.
