20120324841 | ABNORMALITY DETERMINATION APPARATUS FOR PARTICULATE FILTER - An abnormality determination apparatus includes a particulate filter provided in the exhaust passage of an internal combustion engine that collects particulate matter in the exhaust gas discharged from the internal combustion engine, a particulate matter deposition amount detection device provided downstream of the particulate filter, and a abnormality determination portion. The particulate matter deposition amount detection device includes a detecting element that detects the particular matter that flows toward the particulate matter deposition amount detection device and that is not trapped by the particulate filter, and then outputs a value corresponding to a deposition amount deposited the particulate matter on the detecting element. The abnormality determination portion determines, whether an abnormality is present in the particulate filter based on the gradient of an output waveform of the particulate matter deposition amount detection device. | 12-27-2012 |
20130042584 | EXHAUST TREATMENT DEVICE FOR A DIESEL ENGINE - The disclosed exhaust treatment device for a diesel engine can prevent heat damage to a DPF when regenerating said DPF. If a selection device ( | 02-21-2013 |
20130074458 | EXHAUST GAS PURIFICATION SYSTEM - An exhaust gas purification system includes a diesel particulate filter (“DPF”) which collects particulate matter (“PM”) in exhaust gas, an exhaust pipe injector which performs exhaust pipe injection, and a DPF regeneration control unit which performs temperature rise control of an exhaust gas temperature by the exhaust pipe injection to regenerate the DPF when the PM collected by the DPF exceeds a fixed amount and which, during the regeneration, integrates an amount of time during which the exhaust gas temperature exceeds a PM combustion temperature and completes the regeneration when an integrated value thereof reaches a set regeneration completion value. The DPF regeneration control unit aborts the regeneration when, during regeneration, a total amount of the exhaust pipe injection exceeds an upper limit before the integrated value. | 03-28-2013 |
20130081366 | EXHAUST GAS PURIFICATION SYSTEM - An exhaust gas purification system with which diesel particulate filter (“DPF”) regeneration can be continued even when deceleration occurs during the DPF regeneration. The system includes a regeneration deceleration period intake/exhaust control unit that, when a vehicle decelerates during the DPF regeneration, increases an exhaust gas flow rate through an exhaust pipe by controlling respective openings of an exhaust gas recirculation (“EGR”) device and an intake throttle and adjusting a turbocharging amount of a high pressure stage turbocharger. | 04-04-2013 |
20130081367 | EXHAUST GAS PURIFICATION SYSTEM - A diesel particulate defuser (DPD) for collecting particulate matter (PM) in exhaust gas is connected to an exhaust pipe of a diesel engine, and when the amount of PM in the DPD becomes equal to or greater than a predetermined amount, the exhaust gas temperature of the diesel engine is increased by performing exhaust pipe injection and DPD is automatically regenerated. In such an exhaust gas purification system, an exhaust gas temperature during DPD regeneration in automatic regeneration is detected, a difference between the detected exhaust gas temperature and a target regeneration temperature is determined, and in a case where an exhaust pipe injection amount is PID controlled based on the difference, when a transition is made from the traveling automatic regeneration to the idle automatic regeneration conducted during a stop, an integral control term in the PID control is reset to zero to control the exhaust pipe injection amount. | 04-04-2013 |
20150369099 | AUTOMATIC REGENERATION CONTROL DEVICE FOR PARTICULATE FILTER - An automatic regeneration controller for a particular filter comprises an engine controller, a unit controller, and a load application cancellation switch. With filter regeneration being started by determination of particulate accumulation and with an idling or light-load operation being conducted, load request to a work unit is outputted from the engine controller to the unit controller. Then, when load application is not possible or the load application cancellation switch is on and, in addition, exhaust temperature is not maintainable with no load application, a regeneration stop signal is outputted from the unit controller to the engine controller and a regeneration stop signal reception process is conducted in the engine controller, and with no forced load application to a hydraulic unit, fuel addition is stopped to stop automatic regeneration control. | 12-24-2015 |
