发明内容 SUMMARY

[0004] 相比之下具有独立权利要求的特征的、根据本发明的燃烧装置及根据本发明的用于内燃机废气再处理的方法具有其优点,即利用活塞的运动来压缩曲轴壳体中的气体、尤其空气及将该压缩气体输入废气装置,其中通过借助内燃机活塞对曲轴壳体中气体的压缩便可取消一个外部的气体供给装置,例如一个压力储存器或一个附加的压缩空气产生装置。 [0004] In contrast with features of the independent claims, which has the advantages of the burner apparatus of the present invention and a method for an internal combustion engine exhaust gas according to the process of the present invention, namely the use of a compression movement of the piston to the crankshaft in the housing gas, in particular compressed air, and the exhaust gas supply means, wherein an external gas can be canceled by means of an internal combustion engine supply device of the piston compresses the gas in the crank case, for example, a pressure reservoir or an additional compressed-air generator. 因此可不用附加部件及由此非常廉价地实现对废气装置输送压缩气体。 Without additional components and thus can be realized whereby the exhaust gas is a compressed gas delivery apparatus inexpensively.

[0006] 一个有利的进一步构型在于,活塞可运动地设置在一个汽缸中,其中活塞将燃烧室与曲轴壳体对流体密封地相互隔开,活塞与汽缸之间的泄漏损耗除外。 [0006] A further advantageous configuration that the piston is movably disposed in a cylinder, wherein the piston combustion chamber of a fluid-tight housing and a crankshaft spaced from each other, except for leakage losses between the piston and the cylinder. 通过将燃烧室与曲轴壳体对流体密封地隔开便可利用从燃烧室侧作用在活塞上的压力,以便当活塞向着曲轴壳体运动时驱动活塞及在曲轴壳体中达到气体的有效压缩,以致在曲轴壳体中产生压力升高。 By sealing the combustion chamber housing spaced from the crankshaft can utilize the pressure from the side of the combustion chamber acting on the piston to the crankshaft when the piston towards the drive housing and the effective compression movement of the piston reaches the gas in the crank housing in fluid , so as to produce elevated pressure in the crank housing. 这里通过曲轴壳体相对燃烧室的密封在极大程度上抑制了曲轴壳体与燃烧室之间的气体交换并由此抑制了曲轴壳体中的压力下降。 Herein relative to the seal housing via a crankshaft of the combustion chamber gas is suppressed between the crankshaft and the combustion chamber housing to exchange a great extent and thereby inhibit the pressure in the crank case drops.

[0007] 燃烧装置的另一有利的进一步构型在于,曲轴壳体通过一个旁路管路与废气装置的废气通道连接,由此来自曲轴壳体的压缩气体可被利用来对废气通道中的废气再处理或用于废气通道的温度处理。 [0007] Combustion further advantageous refinement of the apparatus comprising, a crankshaft housing are connected by a bypass exhaust gas passage and the exhaust conduit means, whereby compressed gas from the crank housing can be utilized to the exhaust gas passage exhaust gas temperature of the exhaust passage or for the treatment process.

[0008] 燃烧装置的另一有利的进一步构型在于,废气装置包括输送装置,它将流体、尤其用于废气再处理的流体,例如尿素水溶液或内燃机的燃料输送到废气通道中。 [0008] Another advantageous further configuration of the combustion device that the exhaust gas apparatus comprises a conveying means which fluid, in particular for exhaust gas aftertreatment of fluid, such as fuel or urea aqueous solution supplied to the internal combustion engine exhaust gas passage. 变换地同样有利地提出:废气装置包括计量装置,它将流体计量地配给到废气通道中。 Converting likewise advantageously provided: an exhaust gas apparatus comprises a metering means which fluid dispensing metered into the exhaust gas passage. 在此情况下特别有利的是输送装置与计量装置的组合,它们输送来自储备容器的流体及计量地配给到内燃机的废气通道中。 In this case, particularly advantageous it is the combination weighing apparatus with a conveying means, which transport fluid metered and dispensed from the storage vessel into the exhaust gas passage of the internal combustion engine. 但也可尤其利用来自曲轴壳体的气体,以便使通过输送装置输送的流体雾化或以便促使废气通道中流体的燃烧。 In particular, it is also possible to use gas from the crank case, so that by the transport device for transporting or atomizing fluid so as to cause combustion of the exhaust gas passage of the fluid.

[0025] 内燃机10以公知的方式由吸气通道14吸入空气,该空气在燃烧室15中被活塞20压缩。 [0025] In known manner the internal combustion engine 10 by the sucked air intake passage 14, the air compressed by the piston 20 in the combustion chamber 15. 燃料被配给到燃烧室15中,燃料与空气在燃烧室15中混合以形成燃料-空气混合物。 The fuel is dispensed into the combustion chamber 15, fuel is mixed with air in the combustion chamber 15 to form a fuel - air mixture. 通过活塞20对燃料-空气混合物的压缩导致燃烧室15中的压力及温度升高,其中在燃料-空气混合物燃烧时释放出的能量通过活塞20及连杆34使曲轴40处于转动。 By the piston 20 fuel - air mixture compression causes the pressure and temperature rise in the combustion chamber 15, wherein the fuel - air mixture combustion energy released when the crank 20 and the link 34 by the piston 40 is rotated. 在燃料-空气混合物燃烧时形成了废气,该废气在下一工作步骤中由活塞20通过出口13被移到废气通道51中。 Air mixture formed in combustion exhaust gas, the exhaust gas in the next working step by the piston 20 through the outlet 13 is moved to the exhaust passage 51 - fuel. 通过活塞20在汽缸18中的平移运动不仅使燃烧室15中的空气压缩,而且与燃烧室15的压缩并列地在该汽缸18中一个与曲轴壳体30连接的流体容积增大,由此使曲轴壳体30中的压力减小。 By translational movement of the piston 20 in the cylinder 18 is not only compressed air in the combustion chamber 15, combustion chamber 15 and the compression of a fluid volume is connected in parallel with the crankshaft 30 of the housing 18 in the cylinder increases, thereby making pressure in the crank case 30 is reduced. 该物理效应被用来:将曲轴壳体30用作使所谓的“二次空气”注入内燃机10的废气通道51。 The physical effects are used: a crankshaft housing 30 as in so-called "secondary air" injected into the exhaust passage 51 of the internal combustion engine 10. 在内燃机10的压缩阶段中活塞20离开曲轴40地运动,由此使曲轴壳体30的容积增大。 In the compression phase of the internal combustion engine 10, piston 20 moves away from the crank shaft 40, whereby the crankshaft 30 increases the volume of the housing. 在此情况下曲轴壳体30中的压力下降到吸气通道14中的压力以下,以致空气可通过进入阀38由吸气通道14经过管路16流入曲轴壳体30。 In this case the pressure in the crank housing 30 drops to the pressure in the intake passage 14 or less, so that the can 38 through the intake air passage 14 through the line 16 into the valve housing 30 flows into the crank. 进入阀38被构成压力控制阀,它在一个-尤其通过一个阀弹簧的弹簧力确定的-曲轴壳体30中的压力与吸气通道14之间的压力差时打开。 Inlet valve 38 is composed of a pressure control valve, which in a - 14 open when the pressure between the pressure in the crank housing 30 and the difference between the intake passage - in particular determined by the spring force of a valve spring. 通过进入阀38流入到曲轴壳体30中的空气通过活塞20的向下运动而被压缩,其中曲轴壳体30中的压力上升到吸气通道14中的压力以上并使进入阀38关闭。 The inlet valve 38 is compressed by the air flowing into the crank case 30 by the downward movement of piston 20, wherein the pressure in the crank housing 30 rises above the pressure in the intake passage 14 and the inlet valve 38 is closed. 通过活塞20继续的向下运动曲轴壳体30中的压力进一步上升,其中燃烧室25 (15)与曲轴壳体之间的气体交换通过活塞20及活塞环35除泄漏损耗外尽量地被阻止。 20 by the pressure rise further continued downward movement of the piston 30 in the crank housing, wherein the gas between the combustion chamber 25 (15) housing the crankshaft 20 and the piston rings exchange 35 except for leakage losses as much as possible be prevented. 在超过一个确定的压力阈值时曲轴壳体30上的排出阀39打开,以致空气由曲轴壳体30通过旁路管路33流入到内燃机10的废气通道51中。 Discharge valve opened crankshaft housing 3039 upon exceeding a certain pressure threshold, so that the air from the crank case 30 exhaust gas passage 51 flows into the internal combustion engine 10 through the bypass line 33. 在此情况下空气到废气通道51中的导入是在内燃机10的出口13与氧化催化器52之间进行的,以便通过空气与未燃烧的碳氢化合物的放热反应在进入氧化催化器52以前使内燃机10的废气的温度升高,例如在一个冷起动阶段中使氧化催化器52很快地达到工作温度。 In this case, the air introduced into the exhaust passage 51 is performed between the outlet 10 of the engine 13 and the oxidation catalyst 52, so that the reaction in the oxidation catalyst 52 before entering the heat through air unburned hydrocarbons the internal combustion engine 10, the exhaust gas temperature is increased, for example, in a cold start phase manipulation oxidation catalytic converter 52 reaches its operating temperature quickly.

[0026] 也可变换地将用于废气再处理的装置52,54,56以其它的顺序排列。 [0026] 52, 54 may be converted to an exhaust gas processing apparatus for arranging the other order. 同样可变换地从所述的三个用于废气再处理的装置中去除一个或两个,此外可以使用一个所谓的“三通路催化器”来代替氧化催化器,尤其当内燃机10被作成奥托发动机或燃气发动机时。 The same may be transformed from the three exhaust gas treatment apparatus for the removal of one or two, may be used in addition a so-called "three-way catalytic converter" instead of the oxidation catalyst, especially when the engine 10 is made Otto engine or gas engine. 同样可变换地考虑:旁路管路33在另一位置上、尤其在颗粒过滤器54的前面通入废气通道51,以便通过二次空气的导入在进入颗粒过滤器54时提高废气的进入温度,尤其用于颗粒过滤器54的再生。 Likewise converted considered: a bypass conduit 33 in another position, in particular in front of the particulate filter 54 into the exhaust gas passage 51, to entering the inlet temperature of the particulate filter 54 is improved by introducing exhaust secondary air , in particular for the regeneration of the particulate filter 54. 同样可考虑,将旁路管路分叉并在多个位置上通入废气通道51。 Also conceivable, and the bypass line is bifurcated into a plurality of positions on the exhaust gas passage 51.
