Abstract: An exhaust system includes an exhaust gas-carrying pipe and a bypass to the exhaust gas-carrying pipe. The bypass has at least one inlet pipe and at least one outlet pipe. An exhaust gas sensor is arranged in the bypass between the inlet pipe and the outlet pipe in such a way that exhaust gas flowing through the bypass flows through the exhaust gas sensor. An accelerator accelerates the gas flow downstream of the exhaust gas sensor and is coupled to the outlet pipe. At least one inlet portion extends from the inlet pipe to the exhaust gas sensor, the flow cross-section of which is smaller than the flow cross-section of the inlet pipe and opens into an inlet of the exhaust gas sensor.

Abstract: A muffler for an exhaust system has a muffler housing with an inlet chamber fluidically connected an outlet chamber. The inlet chamber has an inlet pipe for supplying an exhaust gas stream into the inlet chamber, and the outlet chamber has an outlet pipe for discharging the exhaust gas stream from the outlet chamber, wherein the inlet pipe and the outlet pipe each have a first pipe portion and a second pipe portion. The inlet pipe and the outlet pipe in the respective first pipe portions are circumferentially impermeable to the exhaust gas stream and are circumferentially porous in the respective second pipe portions. The first pipe portions each have a predetermined length, such that a λ/4 resonator is formed between the respective first pipe portions and walls of the muffler housing associated with the respective first pipe portions.

Abstract: A method of detecting a need for regeneration of an exhaust particulate filter is described. A first pressure drop is detected in a flow section of an exhaust system which includes the exhaust particulate filter. In addition, an exhaust gas temperature is determined. An exhaust gas mass flow flowing through the exhaust particulate filter is then calculated on the basis of the exhaust gas temperature and the pressure drop. Furthermore, a second pressure drop at the exhaust particulate filter is determined. A need for regeneration is detected when the second pressure drop exceeds a predefined pressure limit value that is dependent on the exhaust gas mass flow. Moreover, an exhaust system for an internal combustion engine is presented which includes an exhaust particulate filter.

Abstract: An ammonia combustion engine, a mobile or stationary system having an ammonia combustion engine, and a method comprise operating an ammonia combustion engine with a combustion chamber and an injection device which is in fluidic connection with the combustion chamber. The ammonia can be metered into the combustion chamber. Ammonia is metered into the combustion chamber such that an exhaust gas stream generated by the ammonia combustion engine has a predetermined molar ratio of ammonia to nitrogen oxides independently of the current operating point of the ammonia combustion engine.
