Roewe 550 is difficult to start. What happened?

Its performance feature is that the starter starts to rotate but the speed is not enough and it is weak. Then the starter stopped clicking. When the temperature is low in winter, forgetting to turn off some electrical equipment will cause the vehicle to fail to start, especially when it is used at low speed for a long time in winter, the battery voltage will be lower than the rated value, and it will start abnormally and cannot work normally. At low temperature, the power consumption of cars will be significantly higher than other seasons, and the capacity of batteries will also decrease due to low temperature environment.

2. Carbon deposition

The ignition difficulty caused by car carbon deposition is accompanied by this slight jitter at idle speed. Cleaning the throttle, cleaning the carbon deposit in the air inlet and cleaning the fuel injector can solve the problem.

3. The flow rate of engine oil slows down.

This is more obvious in northern cities where the temperature is particularly low. In winter, the viscosity of engine oil will increase, and the flow of engine oil will become more and more difficult, thus increasing the resistance of the engine and making it difficult to start the car in winter. In this case, the emergency solution is to put the car in a warm environment and start it normally after a period of time. But if you want to solve it completely, you'd better do a professional winter maintenance and change the appropriate oil according to local conditions.

4. The ignition energy of the spark plug is weak.

In order to save money, some car owners do not replace the spark plug after the maintenance period, which will lead to flameout when the ignition energy of the spark plug drops seriously. Moreover, at present, most of the engines of many models are in-cylinder direct injection, so the requirements for spark plugs are higher.
