Automobiles can reduce fuel consumption by cleaning engine carbon deposits, checking the oxygen sensor, regularly replacing the three filters, and inspecting the electronic control unit. Specific methods to reduce fuel consumption: Cleaning engine carbon deposits: Excessive engine carbon deposits are a significant cause, mainly due to the use of unsuitable fuel. It is recommended to add a certain amount of cleaning agent when refueling. If the effect is not obvious, it indicates a large amount of carbon deposits in the engine. In this case, the car must be taken to a 4S shop for professional technicians to clean the carbon deposits inside the engine. Checking the oxygen sensor: As an internal control unit of the car, the oxygen sensor primarily monitors the fuel-air ratio in the engine. Once damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust gas during driving, at which point the oxygen sensor should be replaced. Regularly replacing the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If not replaced for a long time, they become dirty and transmit incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits. Inspecting the electronic control unit: Although the engine's electronic control unit is highly reliable, in vehicles used for a long time, various faults are inevitable. Fuel consumption of Kia K3: The combined fuel consumption of Kia K3 is 5.3-5.4L/100km. There are currently 4 models of this car on sale. The Strive Connect Edition and Smart Drive Sport Edition have a combined fuel consumption of 5.3L/100km. The Fashion Edition, Youth Edition, and Renew Edition have a combined fuel consumption of 5.4L/100km. The above figures are NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 6.3-7.5L/100km.
