摘要： A method for heating an exhaust pipe in a motor vehicle, comprising 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.

摘要： An exhaust purification system of an internal combustion engine comprising an exhaust treatment catalyst (13) arranged in an engine exhaust passage and a heat and hydrogen generation device (50) able to feed only heat or heat and hydrogen to the exhaust treatment catalyst (13). When the warm-up operation of the heat and hydrogen generation device (50) is completed and a reforming action by a reformer catalyst (54) becomes possible, if the temperature of the exhaust treatment catalyst (13) is a preset activation temperature or more, a partial oxidation reaction is performed at the heat and hydrogen generation device (50) and the generated heat and hydrogen are fed to the exhaust treatment catalyst (50). At this time, if the temperature of the exhaust treatment catalyst (13) is less than the preset activation temperature, a complete oxidation reaction by a lean air-fuel ratio is continued and a heat is fed to the exhaust treatment catalyst (13).

摘要： An exhaust gas purification apparatus for an internal combustion engine, capable of carrying out oxidation removal of PM deposited in a filter as a whole in an efficient manner, includes a filter arranged in an exhaust passage of the internal combustion engine and having an oxidation catalyst supported in at least an upstream side portion thereof, and a heating device arranged so as to be able to heat the upstream side portion of the filter irrespective of oxidation reaction heat of the oxidation catalyst, wherein when filter upstream regeneration processing to oxidize and remove deposition PM in the upstream side portion of the filter is carried out by controlling a heating device, an amount of decrease of the upstream side deposition PM by the filter upstream regeneration processing is reflected on an amount of filter PM deposition in the ordinary filter regeneration processing which oxidizes and removes the deposition PM in the entire filter by means of oxidation reaction heat of unburnt fuel generated by the oxidation catalyst supported in the filter, and the filter upstream regeneration processing is ended, even if the thus reflected amount of filter PM deposition is in a state of being larger than a reference amount of deposition which is a threshold value for ending the ordinary filter regeneration processing.

摘要： Injection nozzle 7 and electrode rods 8 and 9 (ignitor) are surrounded by double-cylinder flame stabilizer 10. Toroidal blocking plate 13 closes between inner and outer cylinders 11 and 12 of the stabilizer at its distal end whose proximal end is connected with line 15 for introducing combustion air 14 to between the cylinders. Inflow holes 16 are formed throughout the inner cylinder at its proximal end. Peripheral fins 17 are formed peripherally on the inner cylinder radially inwardly through cutting and bending-up at positions shifted from the inflow holes toward the distal end of the inner cylinder such that combustion air is introduced from circumferentially to form swirling flow inside the inner cylinder. End fins 18 are formed on the blocking plate in fuel injection direction through cutting and bending-up such that combustion air is discharged circumferentially to form swirling flow around flame 21.

摘要： An exhaust gas cleaning apparatus for an internal combustion engine that is mounted on a vehicle includes an exhaust passage that is connected to the internal combustion engine, a filter that collects particulate matter in exhaust gas, an NOx reducing catalyst, a dosing valve that injects urea solution into the exhaust passage, and a controller that performs a filter regeneration process in response to a request for the filter regeneration process. The filter regeneration process includes a first filter regeneration process that is performed during an idle operation of the internal combustion engine and a second filter regeneration process that is performed with the vehicle traveling. When the first filter regeneration process has been performed for a predetermined number of times without being intervened by the second filter regeneration process, the controller does not perform the first filter regeneration process even when a request for the filter regeneration process is made.
