专家都建议，熄火前一两分钟先关闭空调——这样，除了干燥空调出风口、防止空调内孳生细菌以外，更重要的是，如果不关空调就熄火，下次混凝土搅拌车启动时，发动机会带着空调的负荷启动。正确的做法是，启动混凝土搅拌车两三分钟、发动机得到润滑以后，再打开空调。
Experts all suggest that the air conditioner should be turned off one or two minutes before the flameout. In this way, in addition to drying the air outlet of the air conditioner and preventing bacteria from growing in the air conditioner, more importantly, if the air conditioner is not turned off, the engine will start with the load of the air conditioner when the concrete mixer starts next time. The correct way is to start the concrete mixer for two or three minutes and turn on the air conditioner after the engine is lubricated.
所以，如果堵车、等人，发动机长时间处于怠速状态下，更好将空调关闭一会儿，既能减轻发动机负担，还能有效地省油。
Therefore, if the engine is idling for a long time in traffic jams, it is better to turn off the air conditioner for a while, which can not only reduce the burden of the engine, but also effectively save fuel.
空挡滑行 损坏轻量化搅拌车变速箱
Damage to gearbox of lightweight mixer in neutral sliding
手动挡的司机，喜欢空挡滑行，虽然有安全隐患，但因为省油，很多人习惯这么做。
Manual drivers like to slide in neutral gear. Although there are potential safety hazards, many people are used to doing so because of fuel economy.
而对于自动挡车来说，空挡滑行更是有百害而无一利：现在的家用轿车基本都是电喷发动机，混凝土搅拌车发动机转速在1000转以上松掉油门后，混凝土搅拌车发动机也会自动停止给油 ——如果司机的混凝土搅拌车有即时油耗表，就可以清楚地看到这时的油耗为零。而自动挡空挡滑行时因开车速度与发动机转速不同，易出现变速箱的液压管路中油压不足，就会加大摩擦，损害自动变速箱内部的摩擦片，更终导致变速箱出故障。
For the automatic stop car, sliding in neutral gear is more harmful than beneficial: the current family cars are basically EFI Engines, and the engine speed of the concrete mixer truck is above 1000 rpm. When the accelerator is released, the engine of the concrete mixer truck will automatically stop feeding oil ——If the driver's concrete mixer has a real-time fuel consumption meter, you can clearly see that the fuel consumption is zero at this time. When the automatic transmission taxis in neutral gear, due to the different driving speed and engine speed, the oil pressure in the hydraulic pipeline of the transmission is easy to be insufficient, which will increase the friction, damage the internal friction plate of the automatic transmission, and eventually lead to the failure of the transmission.
所以，开惯手动挡的车主，如果拿以前的经验开自动挡车，小心得不偿失。
Therefore, if the car owners who are used to driving in manual gear take the previous experience to drive in automatic gear, they will be careful that the gain is not worth the loss.
车位不平整 伤害搅拌车车架
Damage to mixer frame due to uneven parking space
马路边，经常看到有些混凝土搅拌车一半车轮停在马路牙子上。长期这样停车，会导致四轮落差过大，对车架造成扭曲，甚至影响到车门的闭合。长期在凹凸不平的地面上停车，也会造成类似后果。
On the side of the road, we often see half of the wheels of some concrete mixers parked on the curb. Parking in this way for a long time will lead to excessive drop of four wheels, distortion of the frame, and even influence the closing of the door. Parking on uneven ground for a long time will cause similar consequences.
所以，停车后车轮不回正，也是很伤车的：会伤害方向机拉杆及防尘套，影响转向系统。
Therefore, if the wheels do not return to the right position after parking, it is also very harmful to the car: it will damage the steering linkage and dust cover, and affect the steering system.
刹车不踩到底就挂挡 损伤搅拌车变速器
The transmission of mixer is damaged when the brake is not pressed to the bottom
手动挡的车，混凝土搅拌车的离合器不踩到底强行挂挡会损伤变速器。自动挡车会不会有类似问题呢?
If the clutch of manual transmission and concrete mixer is not pressed to the bottom, the transmission will be damaged. Will there be a similar problem with automatic blocking?
专家说，自动挡的车半踩刹车、刹车灯亮起，就能将挡位推入P挡。如果混凝土搅拌车刹车没踩死就直接推到P挡熄火，路面不平整时混凝土搅拌车会小小挪动一下，会对变速齿轮造成冲击。
Experts say that a car with automatic transmission can push the gear into P when the brake is half pressed and the brake light is on. If the brake of the concrete mixer is not stepped down, it will be directly pushed to the P gear to stop the fire. When the road is uneven, the concrete mixer will move a little, which will impact the speed change gear.
所以，长此以往，肯定对车辆没好处。
Therefore, in the long run, it is certainly not good for vehicles.
打死方向 破坏混凝土搅拌车方向机
Destroy the direction of concrete mixer
开车打死方向的毛病，记者也有：刚学车时，移库手忙脚乱，都是打死方向才敢慢慢松离合器让混凝土搅拌车动起来。专家提醒，经常打死方向盘会对混凝土搅拌车的方向助力泵有损耗，时间长了会加剧助力泵皮带老化，助力泵坏掉，对混凝土搅拌车方向机也有影响。
Driving to kill the direction of the problem, the reporter also has: just learn the car, moving the warehouse in a hurry, are killing the direction to dare to slowly loose the clutch, let the concrete mixer move. Experts remind that killing the steering wheel often will cause damage to the steering power pump of the concrete mixer, which will aggravate the aging of the booster pump belt after a long time, and the damage of the booster pump will also have an impact on the steering gear of the concrete mixer.
