摘要： A lower link (6) is provided with an oil hole (30) in a crank pin bearing portion (11) in order to supply a jet of oil to a connecting portion between an upper pin (4) and an upper link (3). Oil hole (30) is composed of a first oil hole (31) linearly extending from the inner peripheral surface of crank pin bearing portion (11) outwardly in the radial direction, and a second oil hole (32) linearly extending from the outer surface of lower link (6) so as to intersect a distal end portion of first oil hole (31). An inclination angle (θ) of first oil hole (31) with a divided surface (14) set as a reference becomes relatively small, and hence the position of an oil inlet (31 b) involving a problem of stress concentration becomes closer to divided surface (14) exhibiting a relatively low stress. Consequently, the stress concentration at oil inlet (31b) is alleviated.

摘要： A series hybrid vehicle is disclosed that comprises a power generation motor generator (1), a power generation internal combustion engine (2), a travel motor generator (4), a battery (5), and an inverter device (6). The internal combustion engine (2) has a variable compression ratio mechanism (12). When the travel motor generator (4) is performing regenerative braking operation, if the charge state (SOC) of the inverter device (6) is at or above a prescribed level (SOC1), an electric actuator (46) of the variable compression ratio mechanism (12) is operated to cause high/low variation of the mechanical compression ratio and consume excess regenerative power.

摘要： A lower link (7) is formed of two components by being divided at a dividing surface (14) including the central axis of a crank pin bearing portion (11), the two components including a lower link upper (15) with an upper pin bearing portion (12) and a lower link lower (16) with a control pin bearing portion (13). The dividing surface (14) includes a first dividing surface (14a) located more on the upper link side than the crank pin bearing portion (11) and a second dividing surface (14b) located more on the control link side than the crank pin bearing portion (11). In the lower link (7), the first dividing surface (14a) has a surface roughness larger than a surface roughness of the second dividing surface (14b).
