A dollar and a thousand meters high?

The fuel consumption of one yuan and one kilometer, then this specific model is distinguished. The fuel consumption of different displacement models is definitely different. If it is a model with a displacement below 1.6, the fuel consumption is really high. If it is a vehicle with a displacement of 1.8 or more, the fuel consumption of one kilometer in the urban area is relatively normal. Hello, there must be the following reasons for the sudden increase in automobile fuel consumption. First, the engine has too much carbon deposit, which leads to an increase in fuel consumption. This situation is generally easy to accumulate too much carbon after the vehicle travels for 30,000 kilometers. It is recommended to clean up the carbon deposits on the vehicle throttle and engine. Second, the failure of the ignition system leads to an increase in fuel consumption. This situation is generally the phenomenon that the spark plug aging gap is too large or the ignition coil is damaged, which leads to the engine out of the cylinder. This needs to check the spark plug gap in time. If the gap is too large, it needs to be replaced in time. Then use a computer to decode and check whether there is a problem with the ignition coil. Third, if there is a problem, it needs to be replaced in time. Fuel consumption increases due to the blockage of sensors or oil circuits related to the engine. In this case, it is suggested to replace the gasoline filter in time, then clean the fuel injector, read some fault codes of the vehicle engine system with a computer, and focus on checking whether the intake pressure sensor and oxygen sensor are faulty. If there is any fault, the damaged parts need to be replaced accordingly. The above points are the reasons for the increase in vehicle fuel consumption and related detection methods!
