新型汽油发动机 （讲解版）| E0821

One of the world’s largest automotive firms has hailed a technological breakthrough for the petrol engine, in an engineering twist for an industry racing 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 diesel engines because its fuel economy could match diesel’s performance without high emissions of nitrogen oxides or sooty particulates.
