1973年,石油出口国家组织实施石油禁运,使许多国家基于政治和经济原因需要节省能源。后来,日本找到了一个惊人的节省燃料新技术:陶瓷绝热发动机,热能越高,燃料变为动力的效率便越高。氮化硅发动机的抗热能力远优于钢铁发动机,重量比钢制的可减轻40%,燃料可节省30%以上。原型发动机已在进行试验,预料到了2000年时,每五辆新车之中,便可能有一辆装有氮化硅发动机。 In 1973, the Organization of Petroleum Exporting Countries implemented the oil embargo, saving many countries the need for energy conservation for political and economic reasons. Later, Japan found an amazing new fuel-saving technology: ceramic adiabatic engine, the higher the heat, the more efficient the fuel into power. Silicon nitride engine heat resistance is far superior to the steel engine, the weight of steel can be reduced by 40%, the fuel can be saved more than 30%. Prototype engines have been tested and it is expected that in 2000, every five new cars, there may be a fitted with a silicon nitride engine.
