摘要: A powering apparatus has a diesel engine, a low pressure hydraulic tube containing lower pressure hydraulic fluid, a high pressure hydraulic tube containing higher pressure hydraulic fluid, a first hydraulic pump driven by the diesel engine to send hydraulic fluid from the low pressure hydraulic tube to the high pressure hydraulic tube to adjust the pressure difference within a certain range, an exhaust gas recirculating apparatus including a first hydraulic motor driven by the pressure difference and a compressor driven by the first hydraulic motor to compress a portion of exhaust gas and to supply the exhaust gas to an intake air tube, and an exhaust heat collecting apparatus including a turbine rotated by a refrigerant heated by the exhaust gas and a second hydraulic pump driven by the turbine to send hydraulic fluid from the low pressure hydraulic tube to the high pressure hydraulic tube.
