Definitions
- the invention relates to an internal combustion engine with a Supply device for a combustion medium.
- the exhaust gases from an internal combustion engine in particular a diesel internal combustion engine, contain mainly carbon-containing substances in addition to other pollutants Particles, namely soot particles, which increasingly arise when combustion is incomplete.
- Particles namely soot particles
- they are removed by means of a particle filter arranged in the exhaust pipe flowing exhaust gas filtered and collected on the particulate filter. This is problematic because the collected particulate filters affect the exhaust gas flow and one Build back pressure that the function of the exhaust pipe and also the Disturb the internal combustion engine considerably and in extreme cases can put it out of function.
- the invention has for its object in an internal combustion engine stabilize the current regeneration function.
- the particles are continuously burned off and thus the particle filter is continuously regenerated in a combustion temperature range which is lower by the effectiveness of the additive than the temperature range at which the particles are Burn the missing additive.
- the particle mass that accumulates in each case is not sufficient when it is burned to generate temperatures so high that the particle filter could overheat and be damaged.
- the functional range is thus shifted to lower temperatures and thus further away from a critical temperature range.
- the invention also relates to a method for reducing harmful Components in the exhaust gas of an internal combustion engine according to claims 9 to 12, the comparable advantages.
- the additive can consist of one or more active ingredients exist, and it can be the combustion medium in the particulate filter upstream area. It finds a good mix and Even distribution of the additive in the combustion medium takes place when the additive the fuel, especially in the supply line, or directly into the combustion chamber Internal combustion engine is introduced.
- the function is further improved and stabilized when the supply amount of the additive is regulated depending on the operating parameters of the internal combustion engine such as on the size of the output and / or on the Operating temperatur.
- the drawing shows an exhaust system, generally designated 1, which is in shape an exhaust pipe 2 from an internal combustion engine, in particular a diesel internal combustion engine 3, in the form of an Otto engine with several, for. B. four cylinders 4, extends, which are shown as combustion chambers 4a, to each of which one Combustion air supply line 5a, 5b, 5c, 5d extending from one branch feed line 5, in which an air filter, not shown is arranged. Each extends from the combustion chambers 4a Exhaust line branch 2a, 2b, 2c, 2d, which open into the common exhaust pipe 2 and parts of the exhaust pipe 2.
- the internal combustion engine 3 is a supply device 7 for a Associated combustion medium, which consists of a fuel / air mixture and leaves the internal combustion engine 3 as exhaust gas.
- a fuel tank 8 provided by a fuel supply line 9 and a fuel return line 11 with the injection valves, not shown, of the cylinders 4 connected is.
- the supply device 7 is a pump, not shown assigned the injection pressure in the fuel required for the injection generated and also the promotion of fuel from the fuel tank 8 to the Injectors and the return of the fuel in the return line 11 to Tank can cause.
- the supply device 7 is a feed device 12 for an agent or Assigned additive, which is described below and the Combustion medium in the area of the supply device 7 by a suitable one Dosing device is supplied, the additive in the fuel tank 8 or in the Combustion chambers 4a of the cylinder 4 or on the paths in between are supplied can.
- the feed device 12 has one Storage container 13 for the additive, which through a connecting line 14 with the Feed line 9 is connected, the metering device in the Connection line 14 is provided, e.g. in the form of a metering pump 15.
- the amount of the additive that the dosing device sets in functional mode can be constant or depending on certain operating parameters of the internal combustion engine 3 and / or their environment may be variable, particularly depending on the particular Power size of the internal combustion engine 3 can be regulated.
- the exhaust gas emitted by the internal combustion engine 3 flows into Flow direction 16 through the exhaust pipe 2.
- a Oxidation catalyst 17 and a particle filter 18 arranged one behind the other that the Exhaust gas first reaches the oxidation catalytic converter 17, flows through it and then arrives at the particle filter 18 and flows through it.
- the oxidation catalyst 17 and the particle filters 18 are each arranged in a housing 17a, 18a, the Cross-sectional size a multiple of the cross-sectional size from in front of the housing 17a, between the housings 17a, 18a and preferably also after the housing 18a in particular coaxially arranged exhaust pipe sections 2e, 2f, 2g.
- the particle filter 18 filters particles from the exhaust gas and collects them on the actual filter body in the usual way, the exhaust gas the filter body flows through.
- the oxidation catalytic converter 17 works with an excess of oxygen that passes through a correspondingly lean fuel / combustion air ratio or by a so-called secondary air supply in the area up to the oxidation catalytic converter 17 can be provided.
- the exhaust gas flows through the oxidation catalyst 17, the excess oxygen serving for the oxidation of C0 and HC and a nitrogen oxide component such as NO 2 leaving the oxidation catalyst 17 in the exhaust gas.
- the particle filter 18 forms with the oxidation catalytic converter 17 connected upstream of it a so-called CRT system (continuous regenerating trap), which contributes to burning off and converting the particles consisting mainly of carbon on the particle filter 18 in a manner to be described.
- CRT system continuous regenerating trap
- the additive supplied by the feed device 12 is a one that lowers the ignition temperature of the particles.
- Organometallic compounds very beneficial, e.g. Iron octoate, ferrocene or cerium compounds.
- the function of the internal combustion engine 3 and the exhaust system 1 is as follows.
- the internal combustion engine 3 is operated in the sense described above with a lean fuel / air mixture or it can be operated, for example, essentially stoichiometrically if secondary air from a supply line, not shown, is introduced into the exhaust line 2 before the exhaust gas reaches the oxidation catalytic converter 17.
- the latter oxidizes N0 to N0 x or N0 2 , which causes the exhaust gas to the particle filter 18 to continuously burn off the particles on the particle filter 18, the particle filter 18 being regenerated.
- the regeneration starts at lower temperatures, which reduces the average regeneration temperature, and the particle mass that has accumulated in the meantime is not sufficient for the particle filter 18 to burn off heat to a damaging temperature. It can thus be seen that the continuous regeneration brought about by the CRT system and the lowering of the ignition temperature of the particles complement one another advantageously and, at relatively low temperatures, lead to a continuous, failure-prone and stable regeneration of the particle filter 18, the materials of the exhaust system 1 from lower temperatures are claimed and a long service life is achieved with good function of reducing the harmful components in the exhaust gas.
