A diesel engine turbocharger endurance reliability tester comprises a frequency conversion main air blower, a diesel oil supply system, a machine oil supply system, an oil gas mixing system, a combustion chamber, a gas filling air inlet segment, a turbine air inlet segment, a mixing chamber, a current stabilization segment, a bypass pipe and a turbocharger; the tester can adjust an oil injection quantity so as to adjust the temperature of exhaust entering the turbine, can adjust a gas filling quantity and a bypass pipe segment exhaust quantity so as to adjust the flow entering the turbine, andcan burn the injection machine oil so as to test particle influences on the turbocharger; parameters like turbocharger passing temperature, flow and exhaust particles can be singly controlled and linearly adjusted. The tester needs not to make output acting, can effectively use the diesel oil energy to test the turbocharger, and can provide a wider adjustable scope of the exhaust temperature so as to carry out a high-low temperature cycle thermal shock experiment. The diesel engine turbocharger endurance reliability tester is reasonable in design, simple in structure, and suitable for supercharger endurance apparatus optimization designs.
Description
technical field [0001] The invention relates to the field of diesel engine turbocharger testing, in particular to a diesel engine turbocharger endurance reliability testing device. Background technique [0002] To improve fuel economy and reduce emissions, turbochargers are becoming more and more common in engine technology. The turbocharger uses the exhaust gas to drive the turbine to rotate, thereby compressing the intake air and increasing the intake air volume. During the working process, the turbine runs at high speed and is constantly subjected to the thermal shock of the exhaust gas. Therefore, the durability and reliability of the turbocharger in the whole life cycle in the process of design, production and use is a matter of great concern to engineers. It is of great significance to carry out durability reliability test on turbocharger. In the existing technology, there are mainly engine bench experiments, that is, installing the turbocharger on the engine, conne...
