从发动机外特性试验结果看：随着燃料中乙醇含量的增加，发动机最大扭矩和额定功率逐渐降低；

The results of engine full-load characteristic show that the power output of engine decreases as the ethanol volume concentration of diesohol fuel increases.

可变进气正时能够在发动机的低转速到中高转速的阶段多提供10％的扭矩，一直到VVT技术在6000转达到最大气门延迟的时候（在这里蓝线和红线相交）。

The variable intake timing gained 10% more torque across more the lower half of the rev range until the VVT reaches full retard at 6000rpm (which is where the blue line meets the red line).

涡轮增压发动机的最大优点是它可在不增加发动机排量的基础上，大幅度提高发动机的功率和扭矩。

Turbocharged engine of the biggest advantages is that it can not increase in engine displacement on the basis of the substantial increase in engine power and torque.
