    摘要: Engine coolant heating systems and methods that improve waste heat recovery. The systems and methods include a piped connection between the outlet of an exhaust gas recirculation cooler and the main exhaust pipe leading to the vehicle's tailpipe. The systems and methods also include at least one additional valve in the exhaust stream for directing the flow of exhaust appropriately given specific driving conditions.

    摘要: An exhaust gas heat exchanger that includes a stack at least partially surrounded by a housing. The stack includes a first tube, a second tube, and a coolant duct between the first tube and the second tube. A fin is located within the coolant duct. The fin includes a first portion and a second portion and the first tube includes a first portion and a second portion. The first portion of the fin is fixed to the first portion of the first tube such that the first portion of the fin is coupled to the first portion of the first tube for movement with respect to the housing, and the second portion of the fin is supported in the housing for movement relative to the second portion of the first tube to permit movement of the second portion of the first tube with respect to the second portion of the fin.

    摘要: An exhaust gas recirculation cooler includes an inlet configured to receive exhaust gas from an engine, an outlet configured to direct the exhaust gas back toward the engine, and an exhaust gas flow conduit. The flow conduit includes a first end adjacent the inlet, a second end adjacent the outlet, a first narrow side, a second narrow side, substantially flat broad sides extending between the narrow sides, a first channel adjacent the first narrow side and extending between the ends, a second channel adjacent the second narrow side and extending between the ends, and a plurality of third channels located between the first and second channels and extending between the ends. A plate is located at one end of the flow conduit to inhibit the exhaust gas from flowing through at least one of the first channel and the second channel while allowing exhaust gas flow through the third channels.

    摘要: A Rankine cycle for recovering waste heat from an engine includes a Rankine cycle circuit having a pump, a heat exchanger, an expansion device, a cooling device and a bypass circuit. The bypass circuit selectively provides a flow path for working fluid to bypass the expansion device, and includes a flow control valve actuated by a working fluid pressure differential to selectively open or close the bypass flow path. The expansion device includes a drive member directly coupled to a front end accessory drive (FEAD) of the engine such that a rotational speed of the expansion device is dictated by engine speed and the expansion device is free from separate speed control. The expansion device provides torque to the FEAD via the drive member when the system is in a waste heat recovery mode thereby reducing engine load and improving fuel economy.
