In implementing energy saving and emission reduction of the excavator, reducing the energy consumption of the engine is an important component for realizing the energy saving of the whole excavator, and the energy saving is usually carried out by an engine manufacturer. For excavator manufacturers, the conventional energy saving approach is to select engines that match the lower energy consumption. In the process, the rapid installation and matching of the engine on the excavator are realized, the time for optimizing the engine is shortened, and the development speed of the oil-saving project is increased.
Unlike trucks and other work machines, the engine compartment of an excavator for fixedly mounting an engine is extremely limited in space, and the three-dimensional size of the space is generally set to be only slightly larger than the external size of the mounted diesel engine. If an original diesel engine is removed from a mass production excavator to install a new engine, a large amount of manpower and material resources are needed.
