1、第二章2.1、“车开得慢，油门踩得小，就—定省油”，或者“只要发动机省油，汽车就一定省油”，这两种说法对不对？答：均不正确。①由燃油消耗率曲线知：汽车在中等转速、较大档位上才是最省油的。此时，后备功率较小，发动机负荷率较高燃油消耗率低，百公里燃油消耗量较小。②发动机负荷率高只是汽车省油的一个方面，另一方面汽车列车的质量利用系数（即装载质量与整备质量之比）大小也关系汽车是否省油。，2.2、试述无级变速器与汽车动力性、燃油经济性的关系。提示：①采用无级变速后，理论上克服了发动机特性曲线的缺陷，使汽车具有与
2、等功率发动机一样的驱动功率，充分发挥了内燃机的功率，大地改善了汽车动力性。②同时，发动机的负荷率高，用无级变速后，使发动机在最经济工况机会增多，提高了燃油经济性。2.3、用发动机的“最小燃油消耗特性”和克服行驶阻力应提供的功率曲线，确定保证发动机在最经济工况下工作的“无级变速器调节特性”。答：无级变速器传动比I’与发动机转速及期限和行驶速度之间有如下关系：（式中A为对某汽车而言的常数）当汽车一速度在一定道路沙锅行驶时，根据应该提供的功率：businesstoorganize,guide,assist,
