Phenomenon I:
Guangzhou Car Rental at the bottom of the vehicle spills occur.
Reasons for this: after the long-distance running in general There are several possible oil leakage. First of all, the road is bumpy, traffic delay occurred at the end, sometimes inadvertently, a minor hit oil pan, did not found that oil was found to come back; it may be a long time high-speed engine operation, such as power steering pump, gearbox may be due to the load, such as parts of larger oil spills occur. Engine crankcase ventilation maintenance was often neglected problem at low speed, high-speed driving can cause excessive pressure inside the crankcase, oil leakage.
Solutions:
1. To do the maintenance check the chassis, the replacement of damaged parts.
2. To do maintenance so that maintenance personnel to check when the leakage site, corresponding to the replacement of oil seal or fastening.
3. Do maintenance crankcase ventilation when the attention of maintenance parts.
Phenomenon II: Guangzhou car rental vehicle to accelerate, increase fuel consumption; cold start is not smooth, and even cold-start difficulties.
Reasons: more reasons for this failure, after long-distance travel is likely the problem is that the use of the oil problem. The quality of oil filling stations are now mixed, longer if stored gasoline, or petrol quality problem itself, will make too much gasoline in the glial content. Guangzhou Car vehicles using this fuel around the intake valve will have a large number of glial to poor intake valve movement, serious intake valve will campaign in the cold when card lag, the engine is not easy to start.
Solutions:
1. Glial slight carbon deposition can be taken using the method of cleaning liquid.
2. Glial serious carbon deposition can only be removed to clear the cylinder head, but also cleaning circuit. Some provinces and municipalities in the use of ethanol gasoline, there is no problem if the quality is what will not harm the engine, do not have to wash circuit.
Three phenomena: the issue of low speed and rhythmic abnormal sound of the buzzing, high-speed reduced abnormal sound.
Reasons for this: the four-wheel vehicles in Guangzhou Car inaccurate positioning, long-distance traffic of the larger tire wear, tire wear partial form, the issue of abnormal sound.
Solutions:
1. Hands touch the tire tread, if the inside or the outside could feel the sense of rugged patterns have is definitely a reason for that is abnormal sound.
2. Have to do four-wheel position, and then replace the tires.
The phenomenon of four:
At low speed and high temperature, high-speed normal.
Reasons: the water tank and air-conditioning condenser is located in the vehicle top general, long-distance high-speed, water and condenser will be blocked insects and dust, coupled with catkins in spring, condenser cooling effect caused by the deterioration of water tanks, high-speed moving faster as a result of head-flow, water temperature not too high. When the low speed and idling, only on its own condenser cooling water tank, the cooling effect due to poor high temperature will change.
Solutions:
To the service station or repair shop removed the mask of water tanks, use high-pressure gas to insects and dust cleared, and then water washing.
Five phenomena: abnormal sound at low speed and was not obvious, the issue of uniform high-speed hum.
Reasons: a car rental vehicles in Guangzhou wheel bearings will be damaged when this phenomenon. Long-distance running on the wheel bearings is demanding, high-speed bearings in the long run, the use of poor quality or has been a long time the bearings will be damaged due to fatigue, the issue of abnormal sound.
Solutions:
To the service station site on the abnormal sound judge, which concluded that the issue of Car Wheel Guangzhou to carry out the replacement.
The phenomenon of six: High idle after a high-speed, or slightly unstable.
