Definitions
- the invention relates to an exhaust system for an internal combustion engine of a Einspurgenes with the features of the preamble of
- Offenlegungsschrift DE 10 2010 050 055 A1 discloses a method therefor.
- the exhaust system before the catalyst two oxygen sensors and after the catalyst to another oxygen sensor whose signals are evaluated by a control unit.
- Object of the present invention is to show a measure to avoid single-track vehicles above mentioned disadvantages.
- the aim of the invention is to reduce the harmful emissions of
- the first lambda probe as close as possible to the outlet of the internal combustion engine (close to the cylinder head). This distance should correspond to a maximum of ten times the diameter of the outlet opening in the cylinder head of the internal combustion engine.
- the second lambda probe also called monitoring probe
- the distance between the second lambda probe and the catalyst according to the invention should correspond to a maximum of four times the catalyst diameter. This allows a significantly better space utilization within the non-visible area of the EinspurGermanes.
- the system should also be used in exhaust systems that use a muffler, in particular a pre-muffler. It can the
- Figure 1 shows a plan view of an internal combustion engine with an exhaust system according to the invention.
- FIG. 1 shows a plan view of an internal combustion engine 2 with an exhaust system 1 according to the invention for a single-track vehicle, such as
- a motorcycle For example, a motorcycle, a moped, a Mokick or a moped.
- the internal combustion engine 2 has a cylinder head 3, at whose unnumbered exhaust gas outlet an exhaust system 1 is arranged.
- Exhaust system 1 consists essentially of an unnumbered
- the first lambda probe 4 is located between the cylinder head 3 and an emission control system 5.
- As a three-way catalyst is coated in the present embodiment of an additional, not numbered sheet metal dress as heat protection.
- a flow direction of the exhaust gas is represented by two arrows.
- a second lambda probe 6 (oxygen probe) is arranged in the exhaust system 1 after the exhaust gas purification device 5.
- the second lambda probe 6 is at most four times the diameter of the exhaust gas purification system 5 of the
- the diameter of the exhaust gas purification system 5 is the diameter of the catalytically coated monolith, without its sheath. The diameter is valid for the cross-section of circular emission control systems 5. In the case of exhaust gas purification systems 5 which are oval in cross-section, the distance of four times the largest diameter of the catalytically coated one applies
- silencer arranged between the cylinder head 3 and the first lambda probe 4 a, not shown in the present embodiment.
- This silencer is preferably a pre-silencer.
- the cylinder-head-proximate positioning of the first lambda probe 4 means that the first lambda probe 4 is arranged at most ten times the diameter of the exhaust gas outlet in the cylinder head 3 away from the cylinder head 3 in the exhaust system 1.
