自上料水泥攪拌車的發(fā)動機(jī)在進(jìn)行點(diǎn)火時(shí)應(yīng)該短暫且順利，起動后發(fā)動機(jī)轉(zhuǎn)速應(yīng)平穩(wěn)，無抖動和雜音，觀察各種儀表及報(bào)警裝置工作是否正常。更多注意事項(xiàng)就看下面講解吧。

The ignition of the engine of the self loading cement mixer should be short and smooth. After starting, the engine speed should be stable without shaking and noise. Observe whether various instruments and alarm devices work normally. See the following explanation for more precautions.

聽怠速的聲音，應(yīng)該是平穩(wěn)而且連續(xù)的，不應(yīng)該有金屬敲擊聲和其它異響，清晰無雜音質(zhì)量較好的車應(yīng)該只能聽到很小的噪音，且噪音不應(yīng)該刺耳，啟動一小段時(shí)間后，發(fā)動機(jī)轉(zhuǎn)速表指針應(yīng)該很穩(wěn)定。

First of all, listen to the sound of idling. It should be stable and continuous. There should be no metal knocking and other abnormal noises. Cars with good quality should only hear very little noise, and the noise should not be harsh. After starting for a short time, the engine tachometer pointer should be very stable.

變速箱

transmission case

變速器換擋應(yīng)輕便靈活，擋位準(zhǔn)確，不脫擋、不亂擋、無異響，連續(xù)換檔時(shí)應(yīng)該流暢。

The shift of the transmission shall be light and flexible, the gear position shall be accurate, and there shall be no off shift, disorderly shift and abnormal noise. The continuous shift shall be smooth.

空調(diào)

air conditioner

空調(diào)系統(tǒng)出風(fēng)正常，調(diào)整冷熱后應(yīng)該能夠在一定時(shí)間內(nèi)吹出冷/熱風(fēng)。調(diào)整風(fēng)口應(yīng)該可以順利關(guān)閉，調(diào)整風(fēng)的循環(huán)模式，如內(nèi)外循環(huán)、除霜模式、出風(fēng)模式等，應(yīng)該立刻給予響應(yīng)，各風(fēng)口的風(fēng)量相應(yīng)作出變更。出風(fēng)口不應(yīng)該吹出過多污物和異味。

The air outlet of the air conditioning system is normal, and it should be able to blow out cold / hot air within a certain time after adjusting the cold / hot air. Adjust the air outlet to be able to close smoothly. Adjust the air circulation mode, such as internal and external circulation, defrosting mode, air outlet mode, etc., and respond immediately. Change the air volume of each air outlet accordingly. The air outlet should not blow out too much dirt and peculiar smell.

步驟四：行駛檢查

Step 4: driving inspection

如果上述檢查都沒問題，新車也就馬上要到手了，但是別高興的太早，要做后一項(xiàng)檢查了，行駛中的檢查應(yīng)該更加嚴(yán)格。

If the above inspections are all right, the new car will be available soon, but don't be too happy. The latter inspection should be done. The inspection during driving should be more strict.

起步

start

起步過程中應(yīng)該平穩(wěn)，發(fā)動機(jī)、變速箱等處沒有異響。注意起步前進(jìn)的時(shí)候是否有“尖叫”聲，這里的尖叫聲不是指人的尖叫，是皮帶老化，導(dǎo)致表面沒有摩擦力，與皮帶輪摩擦所發(fā)出的尖銳的聲音。

The starting process should be smooth and there should be no abnormal noise from the engine and gearbox. Pay attention to whether there is a "scream" sound when starting and moving forward. The scream here does not refer to the scream of people, but the sharp sound made by the friction with the pulley due to the aging of the belt, which leads to no friction on the surface.

慢速行駛

Slow driving

將車開到比較寬闊的地方以慢速行駛，感覺有無異?，F(xiàn)象，排擋是否順滑，轉(zhuǎn)向是否靈敏，行駛中車身有無異響等。

Drive the car to a wide place and drive at a slow speed. Check whether there is any abnormality, whether the gear is smooth, whether the steering is sensitive, and whether the car body makes abnormal noise during driving.

加速

accelerate

加速時(shí)（新車不要急加速）發(fā)動機(jī)轉(zhuǎn)速過度應(yīng)平穩(wěn)，且無突爆聲和斷火、回火和放炮現(xiàn)象，儀表盤相應(yīng)的指針反應(yīng)靈敏。在加速過程中，換檔時(shí)不應(yīng)該有作車現(xiàn)象，應(yīng)該基本上處于始終平穩(wěn)加速狀態(tài)。

When accelerating (don't accelerate the new car too quickly), the engine speed should be stable, and there should be no sudden explosion, fire break, flashback and shooting. The corresponding pointer on the instrument panel should respond sensitively. In the process of acceleration, there should be no driving phenomenon when shifting gears, and it should be basically in a stable acceleration state all the time.

正常行駛

Normal driving

以不同車速行使過程中整車均應(yīng)平穩(wěn)，穩(wěn)定于某一時(shí)速時(shí)，發(fā)動機(jī)應(yīng)無異常響聲，組合儀表相應(yīng)指針應(yīng)平穩(wěn)，無明顯波動。注意在行駛的時(shí)候車身是否會發(fā)出“咯吱……咯吱……”的響聲，像是沙發(fā)質(zhì)量很差的那種聲音。

When driving at different speeds, the whole vehicle should be stable. When it is stable at a certain speed, the engine should have no abnormal sound, and the corresponding pointer of the combination instrument should be stable without obvious fluctuation. Pay attention to whether the car body will make a "creak... Creak..." sound when driving, like the sound of poor sofa quality.
