Vehicle and propulsion system including an internal combustion engine
摘要：
An internal combustion engine (300) for a vehicle, such as a motorcycle (20), includes a crankcase (380), two banks of cylinders (320a, 320b) projecting from the crankcase (380) in a V-configuration, a plurality of pushrods (364), and a plurality of camshafts (360a, 360b, 360c) supported by the crankcase (380). The two banks of cylinders (320a, 320b) include a first cylinder bank that projects from the crankcase (380) to a first cylinder head (340a), and a second cylinder bank that projects from the crankcase (380) to a second cylinder head (340b). The plurality of pushrods (364) extend between the crankcase (380) and the first and second cylinder heads (340a, 340b), and the plurality of camshafts include only the first, second and third camshafts (360a, 360b, 360c).
摘要（中）：

一种用于诸如摩托车（20）的车辆的内燃机（300），包括曲轴箱（380），从曲轴箱（380）以V形突出的两组气缸（320a，320b），多个 的推杆（364）和由曲轴箱（380）支撑的多个凸轮轴（360a，360b，360c）。 两排气缸（320a，320b）包括从曲轴箱（380）突出到第一气缸盖（340a）的第一气缸组和从曲轴箱（380）突出到第二气缸盖 （340b）。 多个推杆（364）在曲轴箱（380）和第一和第二气缸盖（340a，340b）之间延伸，并且多个凸轮轴仅包括第一，第二和第三凸轮轴（360a，360b，360c）。
