汽车常见故障及处理（Common troubles and treatment of automobile） Common troubles and treatment of automobile Common faults in automobiles Common faults: what is the reason for excessive consumption of gasoline? 1, mechanical factors: Automobile Fault lead to decreased efficiency, please repair plant no fault. Car engines worn out; overhauled engines. 2, tire pressure is inadequate: Please always pay attention to tire conditions, maintain tire pressure, not only fuel-efficient, and increased service life. The brakes bite and can do the slow neutral coasting test automatically to make sure the brakes do not. 3, manual operating factors: warm the car too long; at least 30 seconds after the start, confirm that all warning lights go out, you can go on the road.

Long time unnecessary use of electrical appliances, such as fog, fog lights and other lines to strengthen, because there is no free lunch, power consumption will shift to gasoline consumption. The air conditioning refrigeration efficiency drops. 4, traffic factors: short-term use; engine may not be heated to normal working temperature, which arrived at the destination, because the refrigerator low efficiency, fuel consumption in half engine and cooling water heating, fuel consumption is inevitable, this situation will also lead to car engine carbon deposit. Urban traffic; urban traffic due to traffic jams and traffic lights, stop and go, line consumption even more than the highway. 5, other factors: such as placed too much debris on the car, for a long time will also lead to increased fuel consumption. Two common faults: exhaust black smoke is what reason?
