Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine controller testing device and a testing method. Background technique [0002] Currently, the ambient temperature increases during engine operation. The engine controller is an important component in the engine, and its performance is directly affected by temperature. Among them, the engine controller belongs to the control equipment of the engine system. It mainly completes the fuel flow control according to the input signal of the control system and the flow feedback signal of the fuel regulator, completes the control of the engine according to the predetermined control strategy, and communicates with the upper computer control system through the communication bus. Realize signal transmission, execute control system instructions, and upload engine control signals to telemetry system. Therefore, during the production process of the engine controller, the working perfo...
