发动机缸盖及发动机
摘要：
本发明公开了一种发动机缸盖，发动机缸盖上具有VVT油道，VVT油道包括VVT进油道、凸轮轴轴颈进油道、凸轮轴轴颈回油道和VVT回油道，VVT进油道自发动机缸盖的火力面贯穿至发动机缸盖的调压阀座安装面，凸轮轴轴颈进油道自调压阀座安装面贯穿至VVT进油腔，凸轮轴轴颈回油道自VVT回油腔贯穿至调压阀座安装面，VVT回油道自调压阀座安装面贯穿至缸盖内腔，VVT进油道和凸轮轴轴颈进油道连通形成的通道与凸轮轴轴颈回油道和VVT回油道连通形成的通道相互独立。该发动机缸盖可提高VVT系统的相应速度和工作可靠性。本发明还公开了一种发动机。
摘要（英）：

The invention discloses an engine cylinder cover. VVT oil ways are arranged on the engine cylinder cover and include the VVT oil inlet way, the cam shaft journal oil inlet way, the cam shaft journal oil return way and the VVT oil return way. The VVT oil inlet way penetrates through the flame face of the engine cylinder cover to a pressure regulation valve seat installation face of the engine cylinder cover. The cam shaft journal oil inlet valve penetrates through the pressure regulation valve seat installation face to a VVT oil inlet cavity. The cam shaft journal oil return way penetrates through a VVT oil return cavity to the pressure regulation valve seat installation face. The VVT oil return way penetrates through the pressure regulation valve seat installation face to a cylinder cover inner cavity. The passageway formed after the VVT oil inlet way and the cam shaft journal oil inlet way are communicated is independent of the passageway formed after the cam shaft journal oil return way is communicated with the VVT oil return way. By means of the engine cylinder cover, the corresponding speed and work reliability of a VVT system can be increased. The invention further discloses an engine.
