求翻译：与AchatesPower和EcoMotorsPinnacle的对置活塞二冲程发动机一样，Pinnacle的对置活塞四冲程发动机也是在结构上减少了汽缸盖和气门机构部件，因而大大降低了发动机的内部摩擦和热量损耗，反而使得热转换率大幅提升。据Pinnacle提供的经第三方权威机构认证的试验数据，新技术可将压缩比提高到15:1，燃油效率提升30%～50%，排放减少35%，而制造成本几乎维持不变，传统发动机生产线基本不用改造。是什么意思？

Boxer with achatespower and ecomotorspinnacle piston two-stroke engine, the pinnacle of the opposed piston four-stroke engine is also in the structure to reduce the cylinder head and valve train components, thus greatly reducing the engine's internal friction and heat loss, but makes the heat transf
