Abstract: In accordance with the present invention, a portable wave-swash & coastal-wind energy harvester, once placed on a sea coast in the swash zone captures the mechanical energy contained in: (a) waves in the swash-zone, and (b) coastal-wind. Energy is extracted through: (a) wave turbines, (b) wind turbines, and (c) wave floats. A rotational transmission system with one-way clutches transmits torque to an alternator, while flywheels attached to the axles maintain steady rotation of axles. A wave funnel faces the waves and causes the wave uprush to converge toward wave turbines. A buoyancy chamber at the bottom produces reduction of weight of the portable wave-swash & coastal-wind energy harvester when water in the chamber is emptied and thereby enhances maneuverability of the unit on land and in water, while a stabilization tank at the top when filled with water provides extra weight and stability of the unit in its operating location.

Abstract: In regeneration control of an exhaust gas purification system (1) equipped with NOx occlusion reduction catalyst (11), a decision is made whether operating state of an engine is in a first engine operating range where the exhaust gas temperature is lower than a predetermined mode judgment temperature. If yes, EGR rich control is performed. Otherwise, injection rich control in exhaust pipe is performed. When EGR rich control is performed, a decision is made whether a vehicle is under acceleration or not. If a decision is made that the vehicle is under acceleration, regeneration control is postponed until that decision ends. This enables rich control for regeneration the NOx occlusion reduction catalyst (11), while avoiding deterioration in drivability (comfortableness) during acceleration of the vehicle.
