Description

Spray diesel particulate filter regeneration strategy after the use exhaust stroke with the rising exhaust gas temperature
Technical field
The present invention relates generally to the explosive motor that is used for the pusher motor vehicle, specifically, relates to the diesel engine of the diesel particulate filter (DPF) that has as after-treatment device in vent systems.
Background technique
The known system that is used to handle the waste gas of the vent systems by diesel engine comprises the diesel oxidation catalyst (DOC) relevant with diesel particulate filter (DPF).The combination of these two kinds of after-treatment devices promotes the chemical reaction in the waste gas, and captures diesel engine microparticle matter (DPM) at air-flow when motor passes through vent systems, prevents that thus quite a large amount of pollutants from entering atmosphere.
DPF needs regeneration to keep micro particle catching efficient often.Regeneration relates to the condition that generation will be burnt the particulate that has been captured, otherwise the uncontrolled efficient that can influence DPF of gathering of particulate.
Generation is used to begin and continue the exhaust gas temperature that the condition of regeneration is usually directed to enter DPF and is increased to suitable high temperature.Because diesel engine turns round under relative cooling and oil-poor situation usually, the back injection of diesel fuel is as the part of dpf regeneration strategy, and the exhaust gas temperature that enters DPF with rising also stays the particulate matter that the oxygen of surplus is captured with burning simultaneously.
When vehicle moves in the mode that is of value to dpf regeneration, such as when the running on expressway, can carry out regenerative process under the influence or the situation of not appreciable impact vehicle drive performance hardly, even and become before stow DPM carries out the degree of regeneration to the engine control system command forces at DPF, also can automatically begin regenerative process by the driver or by regeneration beginning strategy.
The inventor has been found that, " closely " back of fuel is sprayed and for the bent axle moment of torsion effect is arranged, thereby the vehicle drive performance there is the influence of highly significant and can to allow some drivers think undesirable, the injection that " closely " back of fuel is sprayed the expansion stroke that is meant After Top Center in (ATDC) about 60 ° of scopes or claimed to take place in the power stroke.
This effect that spray compensation " closely " back requires a large amount of development efforts to realize best possible demarcation so that it minimizes for the vehicle drive Effect on Performance.A consideration item that it may be noted that is that fuel injector gives " closely " ability that spray the back immediately after main injection.Some fuel injectors that have desirable attributes really but may be difficult to give " closely " back injection that horse back needs after main injection.When engine speed was increased to high-speed range, it is more remarkable that this difficulty becomes.
Although " far " in use expansion stroke back injection can give the ability that spray the back at fuel injector required moment in expansion stroke, the injection be meant generation after spray " closely " back is sprayed in " far " back, but in the expansion stroke too " far " thus back injection can cause significant cylinder wall impact can cause oil dilution.
These discoveries and understanding impel the inventor to seek a kind of substitute and better solution that spray the back that is used for, exhaust gas temperature is elevated to the degree that is used to begin and keep dpf regeneration.
Summary of the invention
The present invention relates to a kind of novel strategy that such solution is provided.
By use different back emitted doses in the timing range of atdc in expansion stroke and regularly repeatedly begin regeneration, evaluation result to be to determine optimum value then, thereby the best of seeking to be used for spraying the back is demarcated, in contrast thereto, the inventor has been found that, after a while in exhaust stroke after can be effective when being injected in beginning and keeping dpf regeneration, this has very little influence and need not intensive development efforts for the vehicle drive performance, during as the injection of " closely " in using expansion stroke back.And the present invention avoids relating to fuel injector and give the ability (avoiding the modification for sparger and/or injector driver and controller thus) that spray the back near main injection, avoids relating to and causes the extra cylinder wall of oil dilution to impact.
Have been found that, the back delayed injection neither can be produced above-mentioned undesirable moment of torsion rising in the time range of the part after a while of exhaust stroke, also can not produce undesirable cylinder wall impacts, when doing like this, can between main injection, give the time of fuel injector, especially hydraulically powered fuel injector " inflation again ", and can provide and the same effect of " closely " (expansion stroke) back injection that is used to begin and keep dpf regeneration.
The present invention can be by suitably making amendment and be embodied in the existing system being used for controlling fuel injector processor algorithm regularly.Therefore, need not the hardware that adds.The effort that needs when using " closely " (expansion stroke) back to spray is compared, and just can be in the cornering ability test process develops the best timing in the exhaust stroke by calibration adjustment with less effort.
Therefore, a general aspect of the present invention relates to a kind of diesel engine, and this diesel engine comprises: the fueling system, be used for diesel fuel is spurted into the firing chamber, and fuel burns in the firing chamber to drive motor; Vent systems, the gas that burning produces leads to atmosphere by vent systems, vent systems comprises after-treatment device, and after-treatment device was handled gas before gas leaves vent systems, regenerates but need to be elevated to the regeneration temperature scope by the temperature with gas often; And engine control system, being used to handle the All aspects of of various data with the control engine running, these aspects comprise the regeneration by the fueling and the after-treatment device of fueling system implementation.
Because regeneration request, control system causes that the fueling system gives the firing chamber fueling in the engine cycles that is used for the firing chamber, by the main injection that finishes at the top dead center place that is not later than basically between circuit compression stroke and the expansion stroke with in the circuit exhaust stroke, come fueling then by the back injection, and in expansion stroke, spray without any other fuel, the back is sprayed and is used for the temperature of gas is elevated to the regeneration temperature scope.
Another general aspect relates to by aforesaid engine-driven motor vehicle.
A general aspect relates to the method that a kind of exhaust aftertreatment device that is used for the vent systems of diesel engine begins to regenerate again, diesel engine has fueling system and engine control system, the fueling system is used for diesel fuel is spurted into the firing chamber, fuel burns in the firing chamber to drive motor, engine control system is used to handle the All aspects of of various data with the control engine running, and the aspect comprises the regeneration by the fueling and the after-treatment device of fueling system implementation.
This method comprises by causing that the fueling system begins regeneration for the firing chamber fueling in the engine cycles that is used for the firing chamber, by the main injection that finishes at the top dead center place that is not later than basically between circuit compression stroke and the expansion stroke with in the circuit exhaust stroke, spray fueling then by the back, and in expansion stroke without any other fuel injection.
In the following content that contemplated, the present preferred embodiment of the present invention that is used for implementing optimal mode of the present invention this moment is shown, above-mentioned and other feature and advantage of the present invention as can be seen.This specification comprises accompanying drawing, now is briefly described below.
