气门

"If the engine is turned over too slowly, the unavoidable small leaks past the piston rings and also through the intake and exhaust valves of four-cycle engines will permit a substantial part of the fuel-air mixture to escape during the compression stroke."

如果发动机转速太慢，四行程发动机的活塞环和进排气门就不可避免地有泄漏现象，这会使大量的可燃混合气在压缩行程期间泄漏掉。

Result of research reveals that engine power drops asthe gum content increases when content of gum exceeds 20 mg/ 100 mL. Road driving anaogue test shows thai long time operation with high gum content gasolene will cause greal amount of asphalt like sediment depositing on internal surface or backof engine indution gas passage, muffler...

研究结果表明，胶质含量超过20mg／100mL时，随胶质含量的增加动力性下降。120h道路模拟试验证明，长期使用高胶质汽油会造成进气管、进气道和进气门背部生成大量沥青状沉积物，严重时影响汽油机的正常工作。

The engine was originally conceived in 1974 and is unique in terms of its valves mounted at a compound angle, which allows for a hemispherical combustion chamber shape without using a more expensive twin camshaft arrangement.

该发动机最初设计于1974年，其特色在于将气门安装在一个倾斜的角度上，因此可将燃烧室设计为半球形，从而无需使用成本较高的双凸轮轴设计。

The engine has been submitted to the FIA for homologation and the changes largely have involved inlet and exhaust tuning, as well as oil and fuel development.

引擎遵从了FIA的冻结规则，改变主要是设计进气门和散热管路，还有润滑油与汽油的研发。
