    摘要： A control system (Figure 4) for controlling regeneration of a DPF (42) comprises a favorable-condition-based control section (52), a regular control section (54), and a regeneration termination control section (56). Section (54) initiates regeneration when the actual soot loading (CDPF DELTA P) of the DPF becomes sufficiently large to mandate initiation of regeneration. Section (52) initiates regeneration when the actual soot loading (CDPF DELTA P) reaches an amount (SOOTLOADING) less than the amount at which section (54) mandates regeneration, provided that selected engine operating conditions (MFDES, ENGINE SPEED) disclose conditions favorable for regeneration. Section (56) terminates regeneration when soot loading (CDPF DELTA P) is reduced to some minimum amount (DELTA P MIN) or when conditions for continuing regeneration become unfavorable. By burning trapped soot during favorable conditions, the mandatory regeneration is postponed. This can lower the average amount of trapped soot in the CDPF, thereby lowering the average back-pressure on the engine (20).

    摘要： The invention relates to an element (20) for the exhaust circuit of an internal combustion engine comprising a member (21) arranged in a part of the internal space thereof in such a way that a Venturi is formed for generating a negative pressure used for suctioning (D) and ejecting dust (D) collected by an air filter with exhaust gas (GE). The member (21) comprises at least one intake opening (35) which is embodied upstream of a body (28) is substantially symmetrical with respect to the axis of symmetry (29) which is parallel to the exhaust gas flow direction. Said member (21) is characterised in that the external face of the body (28) is provided with a section which is angled (alpha 1, alpha 2) with respect of said axis and whose inclination increases in the direction of the exhaust gas flow (GE).

    摘要： The invention relates to a gas treatment apparatus ( 1 ) for treating a gas stream. The gas treatment apparatus ( 1 ) comprising addition means ( 14 ) for adding a reducing agent ( 12 ) to a gas stream passing through the apparatus ( 1 ), a guide chamber ( 8 ), a mixing conduit ( 18 ) and a catalytic treatment chamber ( 16 ) containing a catalytic treatment element ( 20 ). The apparatus ( 1 ) is arranged such that gas must pass through the mixing conduit ( 18 ) to pass from the guide chamber ( 8 ) to the catalytic treatment chamber ( 16 ). The mixing conduit ( 18 ) includes an outer wall ( 22 ) surrounding a mixing axis ( 20 ) within the guide chamber ( 8 ). The outer wall ( 22 ) including at least one aperture ( 30 ) through which a gas can enter the mixing conduit ( 18 ) from the guide chamber ( 8 ). The at least one aperture includes guide means ( 32 ) associated therewith for causing at least some of a gas passing through the at least one aperture ( 30 ) to flow circumferentially about the mixing axis ( 20 ) within the mixing conduit ( 18 ) before entering the catalytic treatment chamber ( 16 ).

    摘要： In a vehicle designed so that a driven wheel is driven by uniting an output from an engine and an output from a Rankine cycle system to each other, an accelerator pedal and a throttle valve are connected electrically to each other by a DBW control unit. When an accelerator opening degree (θap) commanded by a driver is increased, a throttle opening degree (θth) is increased by a correcting amount (Δθth) more than a value proportional to the accelerator opening degree (θap), thereby compensating for an output shortage due to a response delay of the output from the Rankine cycle system. When the accelerator opening degree (θap) commanded by the driver is decreased, the throttle opening degree (θth) is decreased by the correcting amount (Δθth) more than the value proportional to the accelerator opening degree (θap), thereby compensating for an output excessiveness due to the response delay of the output from the Rankine cycle system.
