The invention relates to an exhaust gas recirculation (EGR) cooler performance combination testing device, and belongs to the technical field of machinery. According to the EGR cooler performance combination testing device, a work platform is fixedly provided with a combustor, a mixer and a converter, the mixer is connected with a first air cylinder, the converter is connected with a second air cylinder, and the mixer is communicated with the converter through a pipeline provided with a return flow draught fan. The combustor is connected with the mixer, and the converter, the mixer and the combustor are respectively provided with a temperature sensor which is connected with a central controller through a conductive wire. The EGR cooler performance combination testing device can be used for imitating temperature, pressure, flow, and various material composition contained by tail gas discharged by an engine under various work conditions, and therefore various performance indexes of an EGR cooler can be verified and tested.
Description
technical field [0001] The invention relates to a performance comprehensive test device for an EGR cooler, which belongs to the technical field of machinery. Background technique [0002] At present, EGR refers to the exhaust gas recirculation system. There are generally two ways to verify the performance of the EGR cooler: one is to conduct experiments with the help of engine benches, and the other is to use natural gas as a fuel test device. These two methods cannot obtain the data for the optimal design of the EGR cooler, such as the exhaust gas flow, pressure, and temperature of the engine flowing through the EGR cooler under different operating conditions; at the same time, the flow, pressure, and temperature of the coolant flowing through the coolant under various operating conditions And other data all can't be known, and the cycle that these experimental devices need is long in addition, and cost is high. Contents of the invention [0003] Aiming at the above prob...
