自上料水泥搅拌车的发动机在进行点火时应该短暂且顺利，起动后发动机转速应平稳，无抖动和杂音，观察各种仪表及报警装置工作是否正常。更多注意事项就看下面讲解吧。

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.

听怠速的声音，应该是平稳而且连续的，不应该有金属敲击声和其它异响，清晰无杂音质量较好的车应该只能听到很小的噪音，且噪音不应该刺耳，启动一小段时间后，发动机转速表指针应该很稳定。

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.

变速箱

transmission case

变速器换挡应轻便灵活，挡位准确，不脱挡、不乱挡、无异响，连续换档时应该流畅。

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.

空调

air conditioner

空调系统出风正常，调整冷热后应该能够在一定时间内吹出冷/热风。调整风口应该可以顺利关闭，调整风的循环模式，如内外循环、除霜模式、出风模式等，应该立刻给予响应，各风口的风量相应作出变更。出风口不应该吹出过多污物和异味。

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.

步骤四：行驶检查

Step 4: driving inspection

如果上述检查都没问题，新车也就马上要到手了，但是别高兴的太早，要做后一项检查了，行驶中的检查应该更加严格。

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

起步过程中应该平稳，发动机、变速箱等处没有异响。注意起步前进的时候是否有“尖叫”声，这里的尖叫声不是指人的尖叫，是皮带老化，导致表面没有摩擦力，与皮带轮摩擦所发出的尖锐的声音。

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.

慢速行驶

Slow driving

将车开到比较宽阔的地方以慢速行驶，感觉有无异常现象，排挡是否顺滑，转向是否灵敏，行驶中车身有无异响等。

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

加速时（新车不要急加速）发动机转速过度应平稳，且无突爆声和断火、回火和放炮现象，仪表盘相应的指针反应灵敏。在加速过程中，换档时不应该有作车现象，应该基本上处于始终平稳加速状态。

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.

正常行驶

Normal driving

以不同车速行使过程中整车均应平稳，稳定于某一时速时，发动机应无异常响声，组合仪表相应指针应平稳，无明显波动。注意在行驶的时候车身是否会发出“咯吱……咯吱……”的响声，像是沙发质量很差的那种声音。

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.
