Abstract： Energy saving and environmental protection are the themes in the world today. Construction machinery consumes much energy and is the major source of emissions. In order to study how to furthest save energy and reduce emissions，based on the analysis of the state of the art at the technical level of the energy saving technology， the current energy saving and emission reduction technology were expounded，especially the application in the design of compressed natural gas（CNG） wheel loader. For the future development of construction machinery technology，the gap and prospects of the energy saving technology both at home and abroad were analyzed.
