1. Increasing fuel consumption

（1）不良反應(yīng)：攪拌車(chē)油耗不斷增加。

(1) Adverse reaction: the fuel consumption of mixer truck is increasing.

（2）病情原因：油耗增加的原因很多。但常見(jiàn)又容易被忽略的是對(duì)輪胎氣壓的檢查。輪胎胎壓不足不僅會(huì)導(dǎo)致行駛阻力增加，造成油耗上升，還會(huì)影響輪胎的使用壽命。

(2) Cause of illness: there are many reasons for the increase in fuel consumption. But the common and easily overlooked is the inspection of tire pressure. Insufficient tire pressure will not only increase driving resistance and fuel consumption, but also affect the service life of tires.

（3）綠色保養(yǎng)：自備胎壓測(cè)量器，經(jīng)常檢查輪胎氣壓。切記不要忘記備胎的檢查，以免急需更換備胎時(shí)，才發(fā)現(xiàn)備胎不能使用。氣溫高時(shí)胎壓會(huì)比平時(shí)高一些，冷天或陰涼處測(cè)量的胎壓比較準(zhǔn)確。輪胎每行駛1萬(wàn)km要互換位置，避免前后磨損程度相差太大。如果需要更換磨損嚴(yán)重的輪胎，好2個(gè)或4個(gè)一起更換，紋路相同的輪胎可以前后交叉更換。另外，折線花紋的輪胎有助于節(jié)省燃油。

(3) Green maintenance: bring your own tire pressure gauge and check the tire pressure frequently. Remember not to forget the inspection of the spare tire, so as to avoid finding that the spare tire cannot be used when it is in urgent need of replacement. When the temperature is high, the tire pressure will be higher than usual. The tire pressure measured in cold days or in the shade is more accurate. The positions of tires shall be changed every 10000 km to avoid too large difference between front and rear wear. If you need to replace seriously worn tires, replace 2 or 4 tires together. Tires with the same grain can be replaced crosswise. In addition, broken line tires help to save fuel.

2動(dòng)力性能下降

2. Power performance degradation

（1）不良反應(yīng)：發(fā)動(dòng)機(jī)動(dòng)力性能下降，油耗增加，噴嘴堵塞。

(1) Adverse reactions: the engine power performance decreases, the fuel consumption increases, and the nozzle is blocked.

（2）病情原因：很可能是由于長(zhǎng)時(shí)間未更換機(jī)油、機(jī)油濾清器、空氣濾清器和汽（柴）油濾清器造成了油料燃燒不充分，發(fā)動(dòng)機(jī)積炭較多等而致。

(2) Cause of illness: it is likely that the engine oil, oil filter, air filter and steam (diesel) oil filter have not been changed for a long time, resulting in insufficient oil combustion and more carbon deposition in the engine.

（3）綠色保養(yǎng)：建議機(jī)油、機(jī)油濾清器，每行駛約5000km更換一次，空氣濾清器和汽（柴）油濾清器每行駛1萬(wàn)km時(shí)需更換，否則空氣、燃油和機(jī)油中的雜質(zhì)會(huì)造成零件磨損和油路堵塞，從而影響發(fā)動(dòng)機(jī)正常運(yùn)轉(zhuǎn)。

(3) Green maintenance: it is recommended to replace the engine oil and oil filter every 5000km, and replace the air filter and steam (diesel) oil filter every 10000km, otherwise the impurities in air, fuel and engine oil will cause parts wear and oil circuit blockage, thus affecting the normal operation of the engine.

3冷卻液滴漏

3 coolant drip

（1）不良反應(yīng)：車(chē)下滴漏出一灘莫名其妙的液體，且冷卻液的液面高度下降。

(1) Adverse reaction: a pool of inexplicable liquid drips out under the car, and the liquid level of coolant drops.

（2）病情原因：通常情況下，造成滴漏的原因是連接冷卻液箱和發(fā)動(dòng)機(jī)間的橡皮管有裂縫。

(2) Cause of illness: usually, the cause of leakage is a crack in the rubber tube connecting the coolant tank and the engine.

（3）綠色保養(yǎng)：變質(zhì)的冷卻液防銹品質(zhì)下降，不但容易導(dǎo)致散熱器、管路、軟管等部件的損壞，而且因冷卻液的主要成分是乙二醇，滴漏到地上表2混凝土攪拌車(chē)工作裝置常見(jiàn)故障分析及排除方法也會(huì)造成環(huán)境和空氣污染。通過(guò)目測(cè)很難判斷冷卻液是否變質(zhì)，所以要定期更換冷卻液，切莫等到出現(xiàn)故障再去修理。一般建議混凝土攪拌車(chē)每行駛4萬(wàn)km或2年須更換冷卻液，另外每2年須更換冷卻風(fēng)扇皮帶。

(3) Green maintenance: the deterioration of the antirust quality of the coolant will not only easily lead to the damage of the radiator, pipeline, hose and other components, but also cause environmental and air pollution because the main component of the coolant is ethylene glycol, which drips to the ground. Table 2 common fault analysis and troubleshooting methods of the working device of the concrete mixer will also cause environmental and air pollution. It is difficult to judge whether the coolant is deteriorated by visual inspection, so replace the coolant regularly and do not wait until there is a fault. It is generally recommended that the coolant of the concrete mixer should be replaced every 40000 km or 2 years, and the cooling fan belt should be replaced every 2 years.

4發(fā)動(dòng)機(jī)不啟動(dòng)

4 engine does not start

（1）不良反應(yīng)：多次點(diǎn)火，發(fā)動(dòng)機(jī)不啟動(dòng)。

(1) Adverse reaction: multiple ignition, engine does not start.

（2）病情原因：發(fā)動(dòng)機(jī)啟動(dòng)是靠電瓶的電流推動(dòng)火花塞點(diǎn)火完成，因而啟動(dòng)系統(tǒng)出現(xiàn)故障，很可能是由于電瓶生銹或者電瓶液滴漏造成。

(2) Cause of illness: the ignition of the spark plug is completed by the current of the battery when the engine is started. Therefore, the failure of the starting system may be caused by the rust of the battery or the dripping of battery liquid.

（3）綠色保養(yǎng)：每1~2個(gè)月要查看電瓶?jī)?nèi)的電瓶液是否充足。如果不足，可添加蒸餾水至適當(dāng)高度。目前乘用車(chē)大都采用免維護(hù)電瓶，不可擅自加水。此外，每年都要檢查一下電瓶的正負(fù)端接點(diǎn)有無(wú)生銹或污濁的現(xiàn)象。

(3) Green maintenance: check whether the battery liquid in the battery is sufficient every 1 ~ 2 months. If not enough, add distilled water to the appropriate height. At present, most passenger cars use maintenance free batteries, and water cannot be added without authorization. In addition, check whether the positive and negative terminal contacts of the battery are rusty or dirty every year.

5排氣噪聲增加

5 increase of exhaust noise

（1）不良反應(yīng)：發(fā)動(dòng)機(jī)排氣的噪聲增加，廢氣排放量也超標(biāo)。

(1) Adverse reaction: the noise of engine exhaust increases and the exhaust emission exceeds the standard.

（2）病情原因：發(fā)動(dòng)機(jī)的廢氣經(jīng)高溫發(fā)生氧化作用，很可能導(dǎo)致排氣系統(tǒng)泄漏。

(2) Cause of illness: the exhaust gas of the engine is oxidized at high temperature, which is likely to lead to leakage of the exhaust system.

（3）綠色保養(yǎng)：檢查排氣系統(tǒng)的管路、接口處（特別是消音器）是否被廢氣腐蝕，接口墊有沒(méi)有被沖壞。若發(fā)現(xiàn)排氣系統(tǒng)泄漏應(yīng)及時(shí)修理或更換泄漏部件。每年檢查1次不僅可以保證排氣系統(tǒng)正常運(yùn)轉(zhuǎn)，更重要的是減少尾氣對(duì)環(huán)境的污染。

(3) Green maintenance: check whether the pipelines and interfaces of the exhaust system (especially the muffler) are corroded by waste gas and whether the interface pad is washed out. If the exhaust system leaks, repair or replace the leaking parts in time. Checking once a year can not only ensure the normal operation of the exhaust system, but also reduce the pollution of tail gas to the environment.
