The way to treat common winter illnesses
Just as people are prone to colds in winter, vehicles are also prone to "sick" breakdowns in winter. Next, we will talk about the common winter car failure and solutions.
The battery is not charged: in winter low temperature, the battery electrolyte activity is relatively low, the ability to store electricity is poor, especially for electric cars, especially pay attention to always check the battery power, do not forget to turn off the air conditioning, headlights and other power equipment, to avoid power loss, and also to avoid throwing themselves halfway through the freezing.
Starting difficulty: the engine is always difficult to start in winter, in addition to the battery dead vehicle caused by powerlessness, there may be the engine intake parts of the carbon caused by the recommended cleaning of the throttle before winter can reduce the occurrence of this situation. In addition, the oil in winter viscosity will increase, so that the engine resistance is increased is also one of the causes of engine startup difficulties, you can change the viscosity of the appropriate thinning of the oil.
Acceleration weakness: acceleration weakness in low temperatures, is also one of the common failures in winter, the main performance of the car has just started shortly after the need to accelerate the time but can not add up, there is a sense of pulling, a few minutes after the return to normal. The occurrence of this situation may be too much carbon deposits in the spark plugs, not enough hot car caused by the water temperature to reach the normal temperature fault disappears, or spark plugs or ignition coil failure, manifested as a single cylinder or multi-cylinder misfire, while the fault light will be issued to indicate. It is recommended that owners of old cars regularly check the spark plugs, if there is too much carbon or gap is too large, should be cleaned up in time or replaced.
ABS malfunction light is on: in the winter ABS malfunction light alarm, most of the car in the snowy weather driving, the wheel inside the ABS sensor and snow water contact, appear and connect the magnetic induction coil contact is poor, resulting in ABS in the self-test malfunction. Usually after the snow water dries, the fault will disappear. If the warning light still does not go out, you can go to a service station to clean the ABS sensor and perform a fault test to see if there are other problems.
Water temperature can't come up: the engine temperature can't come up or the warming speed is very slow, and the warm air is not hot, this problem is more common. Most of them will show up in traffic or waiting for a red light when the water temperature rises, and the temperature drops rapidly when the car is running. The most important reason for this situation is the thermostat failure, always keep in the state of the large cycle, replace the thermostat immediately after the improvement.
Cold idle jitter: when the engine cold start, if the engine does not have a cold fast idle, or speed unstable failure, the existence of the causes of failure generally include.
1. Engine mechanical failure, such as low pressure in each cylinder.
2 . Intake system failure such as intake pipe leakage.
3. The back of the intake valve, and too much carbon in the intake pipe.
4. Engine management system faults, such as water temperature, intake air temperature signal incorrect line faults, etc..
5. Ignition system faults, such as too much carbon or incorrect gap spark plugs, high voltage wires, distributor cap leakage, and ignition coil damage.
6. Failure of the fuel supply system, such as excessive carbon deposits in the injector internal gel, resulting in poor closure or clogging of the injector.
