搅拌车的油耗问题与什么有关？
一、故障的一般原因
1、 General cause of failure
1、空气滤清器受堵，使进气不畅，造成混合气过浓，或排气管受堵。
1. The air filter is blocked, so that the air inlet is not smooth, resulting in too rich mixture or blocked exhaust pipe.
2、怠速调整不正确。如CO调整错误。
2. The idle speed adjustment is incorrect. Such as co adjustment error.
3、发动机冷却液温度过高或过低。冷却液温度过高，冷却液容易沸腾，动力下降，油耗增高；冷却液温度过低，混合气雾化不好，发动机功率下降，油耗增加。
3. The engine coolant temperature is too high or too low. If the coolant temperature is too high, the coolant is easy to boil, the power decreases and the fuel consumption increases; The coolant temperature is too low, the mixture atomization is not good, the engine power decreases and the fuel consumption increases.
4、点火正时不准确，如点火过迟。
4. Incorrect ignition timing, such as too late ignition.
5、气缸压力过低。实践证明，气缸压力低于规定值，燃油消耗增加20％～25％。
5. Cylinder pressure too low. Practice shows that the cylinder pressure is lower than the specified value, and the fuel consumption increases by 20% ~ 25%.
6、配气相位不正确。
6. Incorrect valve timing.
7、废气再循环阀卡滞而常开。
7. Exhaust gas recirculation valve stuck normally open.
8、冬季使用夏季润滑油或者机油加注过多。
8. Use lubricating oil in winter or fill too much oil in summer.
9、喷油器内部损坏或磨损严重。
9. Internal damage or severe wear of fuel injector.
10、发动机磨损严重。如拉缸、漏气等。
10. The engine is severely worn. Such as cylinder pulling, air leakage, etc.
二、电控方面的原因
2、 Reasons for electronic control
1、冷却液温度传感器有故障。如传感器工作特性发生变化，就会造成喷油修正信号不准。
1. The coolant temperature sensor is faulty. If the working characteristics of the sensor change, the injection correction signal will be inaccurate.
2、进气压力传感器有故障。如传感器输出压力过高，势必造成混合气过浓。
2. The intake pressure sensor is faulty. If the output pressure of the sensor is too high, the mixture will be too rich.
3、进气温度传感器有故障。
3. The intake air temperature sensor is faulty.
4、氧传感器有故障。如传感器内部短路，传感器电压为0，电脑接收稀混合气信号指令增加喷油量。
4. The oxygen sensor is faulty. If the sensor has an internal short circuit and the sensor voltage is 0, the computer receives the lean mixture signal and instructs to increase the fuel injection quantity.
5、节气门位置传感器有故障。如节气门位置信号错误。
5. The throttle position sensor is faulty. If the throttle position signal is incorrect.
6、空气流量计有故障。
6. The air flow meter is faulty.
7、油压调节器有故障。
7. The oil pressure regulator is faulty.
8、ECU及连接器有故障。
8. ECU and connector are faulty.
9、爆燃传感器有故障。
9. The knock sensor is faulty.
10、活性炭罐有故障。
10. The activated carbon canister is faulty.
