评委意见Dual WT-i技术实现了从混合气的吸入,燃烧至排气的高效率。10．5:1的高压缩比,让发动机几乎在所有转速范围内都保持着高效率。低速扭矩增大之后,发动机不用为了同时克服加速阻力和行驶阻力而强制多喷油,这对改善燃油经济性和排放特性有利。丰田汽车公司对于发动机的重视肯定超过了绝大多数的汽车厂商。他们的发动机产品并不多,几个典型排量都只有一款发动机,而且这些发动机还可以共用很多的先进技术。 Judge Opinion Dual WT-i technology achieves high efficiency from inhalation and combustion of the mixture to exhaust. The high compression ratio of 10.5: 1 allows the engine to maintain high efficiency over almost all speed ranges. After the low speed torque is increased, the engine does not have to force more fuel in order to overcome both accelerating and running resistance, which is good for improving fuel economy and emission characteristics. Toyota Motor Corporation’s emphasis on the engine certainly more than the vast majority of car manufacturers. Not many of their engine products, a few typical displacement of only one engine, but these engines can also share a lot of advanced technology.
