The invention relates to an improved method and to an improved device for degassing polymer melts and for neutralizing the thus produced pollutants, characterised by the following characteristics: said pollutants are guided to a plasma source after removal from the degassing area and prior to adding to a filter step or a separator, said plasma source being built and/or formed such that in said plasma source, the pollutants are transformed, entirely or partially, in a plasma aggregate state.

A method for heating an exhaust pipe in a motor vehicle, including a plurality of spark cycles performed in succession at a preset frequency, wherein each spark cycle includes injecting a-preset fuel quantity into an injection area inside of an exhaust pipe in a motor vehicle and generating at least one spark between the ends of a pair of electrodes located in proximity to the injection area in order to start combustion.

Thus, a value of an ionization current flowing between the ends of the pair of electrodes is detected following the extinction of the spark and this ionization current value is compared with a preset reference value.

Therefore, the presence of combustion in the spark cycle is determined, if the ionization current value is greater than the preset reference value, or the absence of combustion in the spark cycle, if the ionization current value is lower than the preset reference value.

A system includes an aftertreatment system coupled to an engine, a heater, at least one sensor configured to determine an exhaust gas temperature, and a processing circuit. The processing circuit is structured to determine whether the exhaust gas temperature is at or below a predefined threshold temperature; provide a first command to control the heater in response to the exhaust gas temperature being at or below the predefined threshold temperature; selectively provide a second command to increase the exhaust gas temperature; and coordinate the first and second commands, where the first command is provided followed by the second command only if the predefined threshold temperature is not attained by the first command.

An internal-combustion-engine warm-up apparatus includes: a post-processing apparatus; a heater arranged upstream of the post-processing apparatus on the exhaust path; a circulation path where air having passed through the post-processing apparatus is fed back to an upstream side of the heater; an air pump that is a blower that feeds air heated by the heater to the post-processing apparatus; a coolant flow path; a heat exchanger; and a control apparatus that controls operation of the heater and the blower, and in a state where the engine is stopped, the control apparatus causes the heater and the air pump to operate, and causes the air heated by the heater to be supplied to the post-processing apparatus and the heat exchanger.

An object is to prevent a wrong diagnosis from being made in an abnormality diagnosis apparatus for an exhaust gas purification system including a filter and a PM sensor. After sensor regeneration is performed, the application of voltage to the PM sensor is started, and thereafter abnormality diagnosis of the PM sensor is performed based on whether or not a signal is output from the PM sensor. Abnormality diagnosis of the filter is performed based on whether or not the output value of the PM sensor reaches a predetermined abnormality criterion value. If the output value of the PM sensor reaches the predetermined abnormality criterion value before a predetermined diagnosis completion time after the abnormality diagnosis of the PM sensor, the filter is diagnosed as abnormal, and the application of voltage to the PM sensor is stopped at that time.

The electric dust collecting apparatus comprises a plurality of discharge electrodes that are disposed in an exhaust flow passage, a ground electrode that constitutes at least a part of an inner wall surface of the exhaust flow passage, and a voltage applying device that is configured to apply voltage selectively from a common power supply to each of the plurality of discharge electrodes. The plurality of discharge regions, each of which includes at least one discharge electrode, are provided in the exhaust flow passage and an electrode-to-electrode distance between the discharge electrode and the ground electrode is different in each of the plurality of discharge regions. The voltage applying device applies voltage to the discharge electrode for each discharge region, and changes the discharge region where voltage is applied to the discharge electrode in accordance with exhaust gas temperature.

A system, device and a method for gas treatment is provided. The gas treatment system comprises a generator, one or more corona devices and separation device disposed in sequence along an exhaust gas flow direction. The generator is driven by a gas flow to generate an alternating supplying voltage. The corona devices are electrically connected to the generator to provide the supplying voltage and generate a first electric field via corona discharge by the supplying voltage such that particulates in the gas passing the first electric field are charged. The separation device is electrically connected to the generator and generate a second electric filed via the supplying voltage to separate charged particulates from the exhaust gas flow.

Methods and systems are provided for a particulate matter sensor. In one example, the sensor may include a concave inlet for admitting exhaust gas from an exhaust passage downstream of a particulate filter into the sensor.
