Abstract: A hydraulic lash adjuster for use in diesel engines including a cylinder head having a first valve, a second valve, and a valve bridge extending between and in contact with both the first valve and the second valve. Where the diesel engine includes a first rocker arm, and where at least one of the first valve and the second valve undergo an oil can valve deflection rate. The hydraulic lash is configured to selectively transmit force between the first rocker arm and the valve bridge, and where the hydraulic lash adjuster is normally in the open configuration, and where the hydraulic lash adjuster changes from the open configuration to a closed configuration at a critical velocity that is greater than the oil can valve deflection rate.

Abstract: A cooling jacket is formed at least in part within the cylinder head mounted on an engine block defining one or more piston cylinders and one or more intake and exhaust ports in communication with each piston cylinder. The cooling jacket includes a first passageway, a second passageway and a turbulence chamber. The first passageway extends from a first flow passage and intersects the turbulence chamber at a first angular position, and the second passageway extends from a second flow passage and intersects the turbulence chamber at a second angular position different from the first angular position. A swirling action is imparted to fluid media passing through the turbulence chamber.
Abstract translation: 至少部分地在安装在限定一个或多个活塞气缸的发动机缸体和与每个活塞气缸连通的一个或多个进气和排气口的发动机缸体中形成冷却套管。 冷却套包括第一通道，第二通道和湍流室。 第一通道从第一流动通道延伸并且在第一角度位置处与湍流室相交，并且第二通道从第二流动通道延伸并且在不同于第一角度位置的第二角位置处与湍流室相交。 向通过湍流室的流体介质施加旋转动作。
