攪拌車(chē)的油耗問(wèn)題與什么有關(guān)？

一、故障的一般原因

1、 General cause of failure

1、空氣濾清器受堵，使進(jìn)氣不暢，造成混合氣過(guò)濃，或排氣管受堵。

1. The air filter is blocked, so that the air inlet is not smooth, resulting in too rich mixture or blocked exhaust pipe.

2、怠速調(diào)整不正確。如CO調(diào)整錯(cuò)誤。

2. The idle speed adjustment is incorrect. Such as co adjustment error.

3、發(fā)動(dòng)機(jī)冷卻液溫度過(guò)高或過(guò)低。冷卻液溫度過(guò)高，冷卻液容易沸騰，動(dòng)力下降，油耗增高；冷卻液溫度過(guò)低，混合氣霧化不好，發(fā)動(dòng)機(jī)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、點(diǎn)火正時(shí)不準(zhǔn)確，如點(diǎn)火過(guò)遲。

4. Incorrect ignition timing, such as too late ignition.

5、氣缸壓力過(guò)低。實(shí)踐證明，氣缸壓力低于規(guī)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、配氣相位不正確。

6. Incorrect valve timing.

7、廢氣再循環(huán)閥卡滯而常開(kāi)。

7. Exhaust gas recirculation valve stuck normally open.

8、冬季使用夏季潤(rùn)滑油或者機(jī)油加注過(guò)多。

8. Use lubricating oil in winter or fill too much oil in summer.

9、噴油器內(nèi)部損壞或磨損嚴(yán)重。

9. Internal damage or severe wear of fuel injector.

10、發(fā)動(dòng)機(jī)磨損嚴(yán)重。如拉缸、漏氣等。

10. The engine is severely worn. Such as cylinder pulling, air leakage, etc.

二、電控方面的原因

2、 Reasons for electronic control

1、冷卻液溫度傳感器有故障。如傳感器工作特性發(fā)生變化，就會(huì)造成噴油修正信號(hào)不準(zhǔn)。

1. The coolant temperature sensor is faulty. If the working characteristics of the sensor change, the injection correction signal will be inaccurate.

2、進(jìn)氣壓力傳感器有故障。如傳感器輸出壓力過(guò)高，勢(shì)必造成混合氣過(guò)濃。

2. The intake pressure sensor is faulty. If the output pressure of the sensor is too high, the mixture will be too rich.

3、進(jìn)氣溫度傳感器有故障。

3. The intake air temperature sensor is faulty.

4、氧傳感器有故障。如傳感器內(nèi)部短路，傳感器電壓為0，電腦接收稀混合氣信號(hào)指令增加噴油量。

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、節(jié)氣門(mén)位置傳感器有故障。如節(jié)氣門(mén)位置信號(hào)錯(cuò)誤。

5. The throttle position sensor is faulty. If the throttle position signal is incorrect.

6、空氣流量計(jì)有故障。

6. The air flow meter is faulty.

7、油壓調(diào)節(jié)器有故障。

7. The oil pressure regulator is faulty.

8、ECU及連接器有故障。

8. ECU and connector are faulty.

9、爆燃傳感器有故障。

9. The knock sensor is faulty.

10、活性炭罐有故障。

10. The activated carbon canister is faulty.
