Abstract: An intelligent post-treatment and regeneration control method for an engineering machinery engine, comprising an automatic and manual regenerated auxiliary load loading control method.

Abstract: An excavator self-detection system comprises a controller, a fuel inlet flow meter, a fuel outlet flow meter and a performance self-detection controller. The fuel inlet flow meter and the fuel outlet flow meter are deployed at a fuel inlet and a fuel outlet of an engine respectively, and are connected to the performance self-detection controller. The performance self-detection controller is connected to the controller. The performance self-detection controller reads the signal values of the fuel inlet flow meter and the fuel outlet flow meter, calculates a fuel consumption value, and reads a machine parameter of the excavator through the controller to determine the performance. A detection method is also provided which uses the above excavator self-detection system. The method comprises performance self-detection, a fuel consumption test, and an efficiency test. The measuring equipment can be set by itself according to different machine types and different communication protocols.

Abstract: An intelligent post-treatment and regeneration control method for an engineering machinery engine, comprising an automatic and manual regenerated auxiliary load loading control method: The method steps include, when the accumulation of the particles in a diesel particulate filter exceeds a specified standard and the exhaust temperature of the engine is higher than the regeneration required temperature, an engine controller transmits an auxiliary regeneration packet; after receiving the packet, a main controller determines the external environment temperature; the main controller supplies corresponding current for the regeneration electromagnetic valve of the particulate filter according to the obtained external environment temperature and the corresponding relationship between a preset environment temperature and a loading current, so as to obtain a load matching the environment temperature; and the main controller monitors the exhaust temperature at the inlet of the diesel particulate filter catalytic conver
