Hot exhaust gases from individual cylinders of a diesel engine are cooled and partially cleansed in respective selected heat exchangers. The cooled and partially cleansed exhaust gases discharged from the plurality of heat exchangers are combined and then passed to a single electrostaic precipitation device for further cleansing.

At this time, all of the other heat exchangers continue to operate in the partial cleansing mode. During the regeneration of the one heat exchanger, the exhaust gases therefrom continue to be mixed with the exhaust gases of the remainder of the heat exchangers. All of the exhaust gases from a given cylinder of the engine always pass through only a single of the heat exchangers.

Process for the purification of a diesel engine exhaust gas and for the utilization of its heat,engine used for driving a heat pump heating device

During the utilization of a diesel engine for driving a heat pump heating device, the purification of the exhaust gases and the utilization of the heat of the engine are raising problems. By means of a heat pump device utilising a water reservoir, from which on the one hand, heat is drawn by the heat pump and on the other hand heat from external sources is supplied to it, this reservoir thus having a temperature close to zero, purification of the gases is achieved by means of a heat exchange with that reservoir which causes a cooling down of these gases and condenses the condensable elements, and noxious substances of the condensate are dissolved. The engine's heat is recycled in the heating circuit, on the one hand directly by heat exchange and on the other hand indirectly via the water reservoir and the heat pump.

Marine exhaust elbow structure with enhanced water drain capability

An exhaust elbow for a marine propulsion system is provided with a stainless steel tube within a water outlet opening to assure that a drain opening remains open even when the exhaust elbow is exposed to a corrosive environment. Since cast iron tends to expand in volume as a result of corrosion of its surface areas, water outlet openings intended to perform a draining function can be partially or fully closed as a result of corrosion. The insertion of a stainless steel tube in one or more water outlet openings of an exhaust elbow assures that an internal water cavity of the elbow can drain when the associated internal combustion engine is turned off, thereby minimizing the possibility of freeze damage to the exhaust components.
