The engagement portion is provided with a pair of arm portions and a coupling portion for coupling base ends of the arm portions each other. An axial rib extending in the axial direction is integrally provided in a central part of a back surface of the coupling portion in the width direction orthogonal to a central axis of a head portion of the piston. An accommodation groove is formed on an inner circumferential surface of a cylinder bore corresponding to the axial rib, such that the axial rib does not interfere with the cylinder bore when the piston moves to the top dead center.

摘要： A waste heat recovery mechanism and a waste heat recovery apparatus generate electricity even when an expander, which is coupled to a combustion engine outputting rotational drive force, is locked. The waste heat recovery mechanism includes an alternator having a rotary shaft, which is coupled to and driven to rotate by a combustion engine, and an expander having an output shaft, which is coupled to the rotary shaft of the alternator. The output shaft applies a rotational drive force to the rotary shaft, thereby assisting rotation of the rotary shaft. A torque limiter is located between the rotary shaft of the alternator and the output shaft of the expander.

摘要： The waste heat recovery system of an engine includes a Rankine cycle, a first bypass passage, a first valve and a control unit. The Rankine cycle allows a working fluid to circulate therethrough. The Rankine cycle has a first heat exchanger, a second heat exchanger, an expander and a condenser. The first heat exchanger exchange heat between the working fluid and the engine or a first intermediate medium exchanging heat with the engine. The first bypass passage allows the working fluid to pass therethrough. One end of the first bypass passage is located at an upstream side of the condenser and the other end is located at a downstream side of the condenser. The first valve opens and closes the first bypass passage. When temperature of the engine or the first intermediate medium is lower than a first predetermined value, the control unit opens the first valve.
