49、cer n financial,11 .发动机负荷12 .发动机燃油消耗率13 .发动机工况三、判断题（正确打，、错误打X）1. 由于柴油机的压缩比大于汽油机的压缩比，因此在压缩终了时的压力及燃烧后产生的气体压力比汽油机压力高。（）2. 多缸发动机各气缸的总容积之和，称为发动机排量。（）3. 发动机的燃油消耗率越小，经济性越好。（）4. 发动机总容积越大，它的功率也就越大。（）5. 活塞行程是曲柄旋转半径的2倍。（）6. 经济车速是指很慢的行驶速度。（）7. 通常，汽油机的经济性比柴油机差，从外特性中的ge曲线比较，汽油机ge曲线比柴油机ge曲线平缓。（）8. 发动机转速过高过低，气缸内充气量

50、都将减少。（）9. 发动机转速增高，其单位时间的耗油量也增高。（）10. 发动机最经济的燃油消耗率对应转速是在最大转矩转速与最大功率转速之间。（）11. 同一发动机的标定功率值可能会不同。（）12. 在测功机上测定发动机功率时，是在不带空气滤清器、风扇、消声器、发电机等条件下进行的。（）四、选择题1. 发动机的有效转矩与曲轴角速度的乘积称之为（）。A、指示功率B、有效功率C、最大转矩D、最大功率2. 发动机在某一转速发出的功率与同一转速下所可能发出的最大功率之比称之为（）。A、发动机工况B、有效功率C、工作效率D、发动机负荷3. 燃油消耗率最低的负荷是（）。A发动机怠速时B、发动机大负荷时C、

51、发动机中等负荷时D、发动机小负荷时4. 汽车耗油量最少的行驶速度是（）。A、低速B、中速C、全速D、超速5. 汽车发动机的标定功率是指（）。A、15min功率B、1h功率C、12h功率D、持续功率6. 在测功机上测量发动机功率，能直接测量到的是（）。playlevelscadresinenterprisedevelopmentintheofbackbonebackbonerole;tofullstrengtheningmembersyouthwork,fullplayyouthemployeesincompanydevelopmentiandsymmetrybreathing.Recallin
