Vehicle maintenance knowledge

1. Clean regularlyair filter, The role of air filter is to purify the air entering the engine, but it is often blocked due to environmental factors, resulting in poor air flow, insufficient gasoline combustion, and further increase in fuel consumption. So you have to clean it yourself once a month and replace it if necessary. 2. Pay attention to the removal of carbon deposits in the combustion chamber. Because the oil is not clean enough or the combustion is not sufficient, carbon deposits are easily generated in the combustion chamber for a long time. The engine itself will produce spontaneous combustion during the working process of the engine, which will affect normal operation and increase fuel consumption. Consumers can ask staff to help inspect and remove them during normal maintenance. 3. CheckSpark plugWhether the combustion in the cylinder is sufficient, the spark plug plays a great role, and also has a great impact on fuel consumption. If some spark plugs do not work, fuel consumption will increase significantly. In addition, the size of the spark plug gap and carbon deposits will also have a direct impact on fuel consumption. If the gap is too small, too much carbon deposits will weaken the ignition ability and cause insufficient combustion and increase fuel consumption. Consumers should pay attention to cleaning and replacement. The spark plugs of common family cars are not expensive. 4. Pay attention to tire pressuretireI rarely pay attention, I think it is enough to do the four-wheel alignment on a regular basis. In fact,tireThe relationship with fuel consumption is also quite close.generallycarThe manufacturer will indicate the normal tire pressure of the tire in the product manual. If the measured tire pressure is too low, it will increase fuel consumption, if it is too high, it will reduce the adhesion and affect the driving safety of the vehicle. Many car repair shops on the roadside can measure tire pressure, and you can ask them to help you when you wash the car. Consumers can regularly go to the repair shop to clean the oil circuit to complete most of the above content. After cleaning, a common household car can generally save 0.5-1L of fuel per 100 kilometers, so if you drive 20000km throughout the year, you can save a total of 426-852 yuan. The prices listed in the table on the left include cleaningThrottleAnd fuel injectors. Normally, the mileage interval for cleaning the oil circuit of a family car is about 30,000km. According to the above-mentioned calculation that the fuel can be saved by "0.5~1L" per hundred kilometers, the total cost can be saved by 639~1278 yuan, which can still save a certain amount in terms of their respective investment. Expenses, but the effect may be more obvious for low-priced models. Related: ·transmissionCauses and solutions of gear skipping faults[汽车修理常识]
