Is 14 liters per 100 kilometers a high fuel consumption?

Normally, a fuel consumption of 14 liters per 100 kilometers is considered very high, and it is recommended that the owner check the vehicle. The reasons for high fuel consumption in cars are as follows: Reason 1: Poor ignition, excessive spark plug gap, or insufficient ignition coil energy. Reason 2: Poor atomization of the fuel injector, malfunction of the fuel pressure regulator, or excessively high fuel pressure. Reason 3: Excessive carbon buildup in the engine, where some of the injected gasoline is absorbed by the carbon deposits. Reason 4: Sensor failure, such as a faulty coolant temperature sensor, which can cause the engine to mistakenly believe it is still in a cold state, continuously sending fuel injection signals, leading to high fuel consumption. Reason 5: Oxygen sensor failure, which can cause fuel trim to fail, and the computer may continuously send fuel injection signals. A faulty air flow meter can result in incorrect intake data.

How to Solve the Problem of Tail Lights Staying On?

Solutions for tail lights staying on: The issue of tail lights staying on may be caused by a damaged brake light switch on the brake pedal or a short circuit in the brake light wiring. Remove the protective panel located above the brake, clutch, and accelerator to expose the brake light switch. Rotate the faulty switch counterclockwise to remove it, then replace it with a new brake light switch. Car tail lights include the lamps and bulbs at the rear of the vehicle. The function of the lamps is to gather and emit the light from the bulbs, thereby enhancing the brightness and range of the light emitted.

Among these, the turn signals and brake lights are symmetrical, with one on each side.

Are there any tips for driving at night?

Tips for driving at night: 1. It is necessary to control the speed reasonably, use the car lights flexibly and appropriately, maintain a proper following distance from the vehicle ahead, and avoid frequent overtaking when visibility is not as good at night; 2. When driving on the highway at night, high beams should be used because highways are not equipped with street lights, and vehicles on highways travel at high speeds. Some drivers may not react in time to emergencies. High beams provide strong light, which helps drivers react promptly. Highways have median barriers, so there is no direct contact with oncoming vehicles, eliminating the need to worry too much about them. Moreover, using high beams helps drivers better observe the condition of vehicles ahead. Night driving can be tiring, so when driving on highways at night, the speed should not be too fast, but it should also not be lower than 80 kilometers per hour.
