摘要： An exhaust system for receiving exhaust gas of an engine is provided. The exhaust system comprises a cooler configured to cool at least a portion of exhaust gas, a pressure sensor configured to measure an exhaust pressure drop across the cooler, and a controller configured to determine exhaust flowrate as a function the measured pressure drop across the cooler. Also provided is a method for operating an engine. The method comprises the steps of combusting a fuel and air mixture, exhausting at least some of the combusted fuel and air mixture as exhaust gas to an exhaust system of an engine, cooling at least some of the combusted exhaust gas in a cooler, measuring pressure drop of the exhaust gas across the cooler, and determining a flowrate of the exhaust gas across the cooler as a function of pressure drop.

摘要： According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device of a work machine includes a gas pressurization assembly. An element of the gas pressurization assembly is removably attachable to a first orifice of the filtering device without removing the filtering device from a work machine to which the filtering device is connected. The system also includes a heat source fluidly connected to the gas pressurization assembly.

摘要： A method of operating an internal combustion engine system includes passing exhaust gases from an engine to an aftertreatment device such as a particulate filter at an exhaust temperature less than a target temperature, and increasing a temperature of exhaust gases passing through the aftertreatment device to the target temperature by controllably restricting exhaust flow upstream the filter. The method still further includes generating a signal indicative of exhaust back pressure and reducing exhaust pressure by selectively reducing airflow to the engine responsive to the signal. An internal combustion engine system and associated control system includes an electronic control unit configured to selectively increase a temperature of exhaust gases passing through a particulate filter to a regeneration temperature via a variable flow restriction device. The electronic control unit is further configured to reduce exhaust pressure upstream the flow restriction device by commanding adjusting an intake airflow control element for the engine responsive to a signal corresponding to exhaust back pressure.
摘要翻译：一种操作内燃机系统的方法包括将废气从发动机排出到诸如微粒过滤器的后处理装置，排气温度低于目标温度，并将通过后处理装置的排气温度提高到目标温度通过可控地限制过滤器上游的排气流动。该方法还包括响应于该信号，通过选择性地减少到发动机的气流来产生指示废气背压并降低排气压力的信号。内燃机系统和相关联的控制系统包括电子控制单元，其被配置为经由可变流量限制装置选择性地将经过微粒过滤器的废气的温度升高到再生温度。电子控制单元进一步构造成响应于对应于排气背压的信号，通过命令调节用于发动机的进气流量控制元件来减少流量限制装置上游的排气压力。
