Abstract: A particulate matter reduction apparatus for a diesel engine, which can reduce particulate matter in a convenient manner with a relatively simple structure, while preventing the shortening of the lifespan of a filter and improving particulate matter burning efficiency, is provided. The particulate matter reduction apparatus includes a housing configured to be placed on a flow path into which exhaust gas is discharged from the diesel engine, a filter configured to collect particulate matter contained in the exhaust gas that flows in the housing, electrodes configured to transmit electronic signals to the filter, and a control unit configured to control the electric signals provided to the electrodes. The particulate matter reduction apparatus is advantageous in that particulate matter is burnt and removed by directly heating the filter. In addition, the apparatus is more convenient, compared to a system which requires a filter to be separated and cleaned.

Abstract: A split type potable water extractor from ambient air and water dispenser is invented, comprising separate water generating block located outside a water use area and water dispensing block located inside a water use area. The water generator block cycles refrigerant through a condenser and an evaporator to create condensation by heat exchange with ambient air circulated by an intake airflow system. The condensate water is collected and purified in a cascade of bactericidal loop to remove impurities. The purified water is pumped to a dispensing apparatus which can be installed in the home or other area of water use separate from the water generating block. If any one of the functional parts or units of water generator is disabled the water generator immediately stops operating to deliver water to the tank of the dispensing apparatus.
