The fuel consumption of new batteries in cars becomes higher.
At present, the engines of vehicles have engine computers, referred to as ecu. Vehicles equipped with automatic transmission also have a transmission computer, referred to as tcu. Then both ecu and tcu have learning function. These two computers will learn the driver's driving habits and store this information so as to adjust the operation of the engine and gearbox according to the driver's driving habits.
If the battery is replaced, the previously learned and stored information will be erased, so the fuel consumption of the car will increase after the battery is replaced, but this is only temporary. After ecu and tcu learn again, the fuel consumption of the vehicle will return to the level before battery replacement.
Some drivers will often clean the throttle of the car, so it is best to re-match the ecu after cleaning the throttle, otherwise it will also lead to an increase in vehicle fuel consumption. Automobile ecu is very advanced and has powerful self-learning function. If the throttle produces carbon deposit, ecu will detect it, so ecu will change the mode of controlling the throttle. After cleaning up the carbon deposit, if the ecu still controls the throttle according to the control mode of carbon deposit generated by the throttle, the fuel consumption of the vehicle will increase.
