摘要： In a deterioration diagnosis apparatus for a selective catalytic reduction (SCR) catalyst in which when an air fuel ratio of a mixture to be combusted in an internal combustion engine is a lean air fuel ratio, inducement processing is executed which is to induce a water gas shift reaction in a pre-stage catalyst, by changing the air fuel ratio of the mixture from the lean air fuel ratio to a predetermined rich air fuel ratio, and diagnosis processing is executed which is to diagnose deterioration of the SCR catalyst based on an output difference between two air fuel ratio sensors at the time of the execution of the inducement processing, when the SCR catalyst is in a state of being subjected to sulfur poisoning resulting from the execution of the S purge processing of the pre-stage catalyst, diagnosis processing is not executed.

摘要： A system, a use of such a system and a multi system for cleaning exhaust gas from a combustion engine. The system comprises a first exhaust gas scrubber to communicate with a scrubber water circulation tank. A first outlet of the first exhaust gas scrubber is connectable to a first inlet of the scrubber water circulation tank, and a first inlet of the first exhaust gas scrubber is connectable to a first outlet of the scrubber water circulation tank, to enable circulation of scrubber water between the scrubber water circulation tank and the first exhaust gas scrubber. An air supply device feeds air into the first exhaust gas scrubber to aerate the scrubber water during its passage through the first exhaust gas scrubber. Accordingly, a second inlet of the first exhaust gas scrubber is arranged to be connected to an outlet of the air supply device.

摘要： A proportional heater controls a marine diesel powered generator with a diesel particulate filter (DPF). A proportional control is applied to the heater based upon exhaust temperature. The heater heats exhaust gas to a regeneration temperature to remove soot and sulphur from the processed gas when the diesel fuel has a sulphur content exceeding 1,000 ppm. The heater is supplied power via SCRs to reduce electromagnetic and radio frequency interference. A manual override permits the operator to set a temperature setpoint, force the heater to meet a certain temperature and establish a load bank for diesel engine electrical generator set.

摘要： A control device for a scrubber includes a converter which calculates a minimum amount of seawater: a minimum amount of seawater necessary for an absorption reaction of the sulfur oxide by the seawater, from an engine output and a sulfur content of fuel oil; another converter which calculates a corrected amount of seawater: an amount of seawater at which the sulfur oxide in the exhaust gas discharged from the scrubber is equal to or less than a set value; a summing element which calculates a set amount of seawater by summing the minimum amount and corrected amount of seawater; a pump control device which implements control such that seawater corresponding to the set amount is supplied to the scrubber; and an alkalinity setting device which sets the alkalinity of the seawater in accordance with traveled waters. The amount of seawater supplied to the scrubber is adjusted based on the alkalinity.

摘要： An exhaust gas after-treatment system for an internal combustion engine, with a particle filter arranged downstream of an internal combustion engine for filtering soot out of the exhaust gas, and with an oxidation catalytic converter arranged upstream of the particle filter and downstream of the internal combustion engine for the oxidation of SO2 into SO3. The SO3 and/or precipitated H2SO4 serves for the oxidation of soot in the particle filter and thus for the regeneration of the particle filter.
