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.

Hail：庆祝
Twist：改变
Embrace：拥抱
Spark plug：火花塞
Petrol：汽油
Existential：存在的
Emission：排放
Nitrogen oxides：氮氧化物
