    • An internal combustion engine for a vehicle includes a crankshaft (68), a piston (74) movable through a cycle, a piston rod (76) connecting the piston (74) and the crankshaft (68), an oil pan (70) spaced from the crankshaft (68), and an oil source providing pressurized oil. An inventive windage tray (32) is positioned between the crankshaft (68) and the oil pan (70). The windage tray (30) includes a passage having an inlet port (36) receiving the pressurized oil and a first outlet port (38) directing a first stream of the pressurized oil at the piston (74). In a preferred embodiment of the present invention, the passage further includes a second outlet port (42) directing a second stream of pressurized oil at the piston (74). The first outlet port (40) is positioned to direct the first stream of pressurized oil upon the piston (74) unobstructed by the piston rod (76) during a first portion of the piston cycle. The second outlet port (42) is positioned to direct the second stream of pressurized oil upon the piston unobstructed by the piston rod (76) during the remaining portion of the piston cycle.
    • 一种用于车辆的内燃机包括曲轴,可循环移动的活塞,连接活塞和曲轴的活塞杆,与曲轴间隔开的油盘以及提供加压油的油源。 本发明的防风托盘位于曲轴和油盘之间。 防风托盘包括具有容纳加压油的入口的通道和在活塞处引导加压油的第一流的第一出口。 在本发明的优选实施例中,通道还包括在活塞处引导第二加压油流的第二出口。 第一出口定位成在活塞循环的第一部分期间将第一加压油流引导到由活塞杆阻挡的活塞上。 第二出口定位成在活塞循环的剩余部分期间将第二加压油流引导到活塞杆不受阻塞的活塞上。
