POWERING APPARATUS

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.

主权项

1. A powering apparatus comprising:
a diesel engine; a low pressure hydraulic tube containing hydraulic fluid; a high pressure hydraulic tube containing hydraulic fluid, hydraulic pressure in the high pressure hydraulic tube being higher than hydraulic pressure in the low pressure hydraulic tube, a difference in hydraulic pressure between the high pressure hydraulic tube and the low pressure hydraulic tube being within a certain range; 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 and configured to adjust the difference in hydraulic pressure between the high pressure hydraulic tube and the low pressure hydraulic tube within a certain range; an exhaust gas recirculating apparatus including
a first hydraulic motor driven by the difference in hydraulic pressure between the high pressure hydraulic tube and the low pressure hydraulic tube anda compressor driven by the first hydraulic motor to compress a portion of exhaust gas of the diesel engine and to supply the exhaust gas to an intake air tube of the diesel engine; and an exhaust heat collecting apparatus including a turbine and a second hydraulic pump, the turbine being configured to rotate by a refrigerant heated by absorbing heat of the exhaust gas, the second hydraulic pump being driven by the turbine and configured to send hydraulic fluid from the low pressure hydraulic tube to the high pressure hydraulic tube.
