  • Patent number: 8915545
    Abstract: A chair for use in combination with a table. The chair has a seat, a back and four legs. To the back, an upper backrest and a lower backrest are secured. The lower backrest can rotate with respect to the back. While projecting forwards from the back, the lower backrest engages with the upper surface of the top plate of the table. The chair is therefore supported, with the legs suspended above the floor.

  • Patent number: 8549843
    Abstract: In in-cylinder fuel multi-injection conducted during forced regeneration of a diesel particulate filter (“DPF”), control maps for multi-injection are constructed so as to be different for a first gas temperature raising control, which raises a catalyst temperature index temperature to a first judgment temperature only by multi-injection, and for a subsequent second exhaust gas temperature raising control, wherein post-injection is conducted in addition to multi-injection to raise a filter temperature index temperature to a second judgment temperature. In so doing, exhaust gas flowing into the DPF can be rapidly raised in temperature when performing forced regeneration of the DPF, thereby shortening the forced regeneration time and improving fuel consumption for forced regeneration.

  • Patent number: 8522533
    Abstract: When an internal combustion engine is in a low rotation speed driving condition, a duration of the low rotation speed driving condition is measured, and when this duration exceeds a predetermined time, the forced regeneration control is performed. Thus, even when an exhaust flow rate is small and an estimation of a particulate matter accumulated amount due to a pressure difference between front and back sides of a filter is difficult, a forced regeneration time can be accurately judged, the deterioration of fuel efficiency that is caused by excessive trapped particulate matter can be avoided, and thermal runaway that is caused by the excessive particulate matter, and the melting damage of the diesel particulate filter due to this thermal runaway, can be prevented.

  • Patent number: 8171725
    Abstract: In an exhaust gas temperature raising control for recovering purification ability of an exhaust gas purification device of an internal combustion engine, the exhaust gas temperature is efficiently raised to a target level without producing white smoke. In recovery control of the exhaust gas purification device, when the temperature of the exhaust gas flowing into the exhaust gas purification device is lower than a predetermined judgment value, a first exhaust gas temperature raising control that does not include post injection but includes intake air restriction is performed, and when equal to or higher than the predetermined judgment value, a second exhaust gas temperature raising control that includes both the post injection and the intake air restriction is performed to set an intake air restriction amount in the first exhaust gas temperature raising control greater than an intake air restriction amount in the second exhaust gas temperature raising control.

  • Patent number: 8011178
    Abstract: In regeneration control in a manual regeneration mode, when a first exhaust gas temperature of an exhaust gas flowing into an oxidation catalyst device is higher than a predetermined determining temperature and an exhaust gas temperature flowing into a DPF device is higher than a predetermined determining temperature and when an intake temperature becomes higher than a predetermined third determining temperature, second exhaust gas temperature control carrying out post injection in addition to multi injection is stopped and switched to third exhaust gas temperature rise control carrying out the post injection in addition to normal injection. Thus, temperature rise of an engine cooling water can be restricted without stopping an air conditioner, and possible overheating of the engine can be prevented.

  • Patent number: 7716920
    Abstract: The present invention provides an engine exhaust gas purification device comprising a filter B provided in an exhaust passage (10) of an engine (1) for trapping particulate matter contained in the exhaust gas, a catalyst A for regenerating the filter B by burning the particulate matter trapped in the filter B, an EGR valve (8) provided in an EGR passage (7) linking the intake side and exhaust side of the engine 1, an injector (2) for injecting fuel into a cylinder, and control unit (20) for controlling the injector (2) and EGR valve (8). During regeneration of the filter B, the control unit (20) close the EGR valve (8) when fuel injection from the injector (2) is controlled to supply unburned fuel components to the catalyst A, and open the EGR valve (8) when no fuel is injected from the injector (2) upon a request for speed reduction or the like. In so doing, residual unburned fuel components in the EGR passage (7) are scavenged by air.

  • Publication number: 20090235647
    Abstract: In regeneration control in a manual regeneration mode, when a first exhaust gas temperature (Tg1) of an exhaust gas flowing into an oxidation catalyst device (12a) is higher than a predetermined determining temperature (Tc1) and an exhaust gas temperature (Tg2) flowing into a DPF device (12b) is higher than a predetermined determining temperature (Tc2) and when an intake temperature (Ta) becomes higher than a predetermined third determining temperature (Tc3), second exhaust gas temperature control carrying out post injection in addition to multi injection is stopped and switched to third exhaust gas temperature rise control carrying out the post injection in addition to normal injection. Thus, in the regeneration control in the manual regeneration mode of a continuous regeneration type DPF device (12) of an engine(10), temperature rise of an engine cooling water can be restricted without stopping an air conditioner, and possible overheat of the engine (10) can be prevented.
