摘要： An exhaust purification apparatus includes a regenerative burner for repetitively regenerating a trap element located in the exhaust system of an internal combustion engine. The regenerative burner has a combustion chamber adapted to permit flow of exhaust gas from the engine exhaust conduit to the trap element. A hollow member is disposed within the combustion chamber to define an evaporation chamber therein. The hollow member has a side wall formed with a number of flame holes to permit fluid flow from the evaporation chamber into the combustion chamber. The evaporation chamber has a supply of air-fuel mixture through a mixture conduit having an end terminating in a discharge outlet opening into the evaporation chamber. The mixture conduit has a portion extending through the combustion chamber to promote fuel evaporation during a trap regeneration operation.

摘要： A filter is disposed in the exhaust passage of an internal combustion engine in order to trap particles suspended in exhaust gas. A burner serves to burn off the particles deposited on the filter. Either the pressure in the exhaust passage at a point upstream of the filter or the pressure difference in the exhaust passage across the filter is selectively sensed. In place of sensing the pressure difference, the pressure in the exhaust passage at a point downstream of the filter may be sensed. The ratio between the upstream pressure and the pressure difference, or the ratio between the upstream pressure and downstream pressure is determined an as indication of the degree of clogging of the filter. The burner is operated on the basis of this ratio.

摘要： A first filter is disposed in an engine exhaust passage. A second filter is disposed in the engine exhaust passage at a location downstream of the first filter. Thus, the first and second filters are connected in series with one another. The first and second filters are designed so that an amount of exhaust particles trapped by the first filter is greater than an amount of exhaust particles trapped by the second filter. A pressure across the series combination of the filters may be detected. The filters may be rejuvenated when the detected pressure across the series combination of the filters reaches a reference pressure.

摘要： A filter disposed in an engine exhaust passage traps particles suspended in exhaust gas. A burner serves to burn off the particles deposited on the filter. The pressures in the exhaust passage at points upstream and downstream of the filter are sensed. A determination is made as to whether or not the sensed upstream pressure is lower than a preset level. When the sensed upstream pressure is not lower than the preset level, the degree of clogging of the filter is deduced on the basis of the sensed upstream and downstream pressures. When the sensed upstream pressure is lower than the preset level, the degree of clogging of the filter is deduced on the basis of a time elapsed since the moment at which the sensed upstream pressure dropped below the preset level and on the basis of the sensed upstream and downstream pressures obtained immediately prior to that moment.

摘要： An exhaust gas recirculation control system for a compression-ignition internal combustion engine or diesel engine including an intake throttle valve in an intake passage and an exhaust gas recirculation passage opening downstream of the intake throttle valve, comprises a shut-off valve in the exhaust gas recirculation passage so that the shut-off valve is closed in the proximity of a full load region of the engine.The system further comprises a link mechanism interlocking the intake throttle valve with the control means of the fuel injection pump, which link mechanism is operative to begin to open the intake throttle valve lagging behind a commencement of an operation of the control means of the fuel injection pump and to completely open the intake throttle valve prior to an arrival of the control means at its full operating position, thereby stabilizing its exhaust gas recirculation control characteristic in low and high load regions, effectively reducing NOx to ensure the stability of the engine in the low load region, reliably preventing black exhaust gases in the high load region and improving the full output of the engine.

摘要： A nitrogen oxide absorbing material (38) which absorbs nitrogen oxide when the reduction component concentration of exhaust gas in the exhaust passage (31) of an engine (1) is lower than a predetermined concentration, and discharges nitrogen oxide when the reduction component concentration of exhaust gas in the exhaust passage (31) of the engine (1) is higher than the predetermined concentration, and a catalyst (38) which promotes reduction of the discharged nitrogen oxides by a reduction component are provided. A controller (40) first reduces the reduction component concentration of the exhaust gas over a first predetermined time period by, for example, advancing the fuel injection timing. The controller (40) then increases the reduction component concentration of the exhaust gas over a second predetermined time period by, for example, retarding the fuel injection timing.

The temperature at the inlet and outlet of a trap in which particulate matter is accumulated are monitored and measures such as throttling the induction and exhaust are implement in addition to energizing a heater disposed immediately upstream of the trap as required in order to elevate the trap temperature and to induce and maintain the reburning during a trap regeneration. The pressure differential across the trap can be used to determine the amount of incombustible matter (ash) which has accumulated in the trap and to modify the regeneration timing. When the temperature of the exhaust gases cannot be raised sufficiently, a by-pass is opened to attenuate cooling of the trap by the low temperature gases.

摘要： A piston crown is formed with a cavity including a first flame deflecting member which is located amid three flame dispersion zones and which splits burning gases ejected from a transfer port into a first dispersion zone, while the piston is proximate its TDC position, into two flows. The arrangement additionally induces the two flows to assume two essentially symmetrical swirling patterns in second and third dispersion zones. After the piston has descended by a predetermined amount, the burning gases are supplied directly into the second and third zones. Important design considerations which influence the efficiency with which the air in the main combustion chamber include the angle at which the gases are directed toward the piston crown, the location of the first flame splitting member with respect to the site where the flame initially impinges on the first dispersion zone, the angle at which the flame is split and directed toward the second and third zones, the areas of the first, second and zones in which the swirling air patterns are produced and the velocity at which the burning gases flow into the second and third zones.
