Abstract
The invention discloses an obliquely-arranged valve cylinder head of a gasoline engine. The obliquely-arranged valve cylinder head comprises a cylinder head body, a gas inlet path and a gas exhaust path, where the gas inlet path and the gas exhaust path are arranged in the cylinder head body. A gas inlet door is arranged on the cylinder head body and corresponds to the gas inlet path. A gas exhaust door is arranged on the cylinder head body and corresponds to the gas exhaust path. The top of the gas inlet door inclines towards the gas inlet path side. The top of the gas exhaust door inclines towards the gas exhaust path side. An included angle between the axis of the gas inlet door and the axis of the gas exhaust door is less than or equal to 35 degrees. Due to the facts that the top of the gas inlet door inclines towards the gas inlet path side and the top of the gas exhaust door inclines towards the gas exhaust path side, gas inlet and exhaust resistance can be reduced, and gas inlet efficiency is improved. The power of the gasoline engine is improved, the emission of the gasoline engine is lowered, and meanwhile, installation with other components on the cylinder head body has good adaptability so that the arrangement of the other components cannot be affected. The included angle between the axis of the gas inlet door and the axis of the gas exhaust door is less than or equal to 35 degrees, and therefore a sufficient angle of inclination can be ensured, and smooth gas inlet and gas exhaust can be guaranteed. Meanwhile, the situations that a sufficient width is formed between the gas inlet door and the gas exhaust door, and a nose bridge area has a sufficient width are also ensured. The obliquely-arranged valve cylinder head of the gasoline engine has a better cooling effect.
