夏说英语新闻晨读 第289期:新型汽油发动机

 本期内容：
One of the world's largest automotive firms has hailed a technological¹ breakthrough for the petrol engine, in an engineering twist for an industry racing² to embrace the electric car. Japanese car manufacturer Mazda claims to have designed a vehicle that will largely eliminate the need for spark plugs in petrol engines, increasing fuel efficiency by as much as 30%. The development also increases the existential threat facing diesel³ engines because its fuel economy could match diesel’s performance without high emissions⁴ of nitrogen oxides or sooty particulates⁵.
