After cleaning the throttle body, if the idle speed is high, you can try removing the carbon deposits on the throttle body and check if the opening and closing mechanism of the throttle body is damaged. If you use a diagnostic tool to reset it, the optimal idle speed data will immediately replace the pre-cleaning data, causing the engine speed to quickly return to the best target speed. Below is some relevant information about the throttle body: 1. Concept: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to produce work. It connects to the air filter at the top and the engine block at the bottom, earning it the nickname "the throat of the car engine." 2. Purpose: The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to produce work. It connects to the air filter at the top and the engine block at the bottom, earning it the nickname "the throat of the car engine."

What is the fuel tank capacity of the Elantra in liters?

The fuel tank capacity of the Hyundai Elantra is 47 liters, as officially announced. The Hyundai Elantra uses 92-octane fuel, with a fuel consumption of 5.2-5.4L per 100 kilometers. A full tank can cover a distance of 870-903 kilometers. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank. The fuel level is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when the gauge shows 2 segments remaining to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safe limit, and there is additional space from the safe limit to the tank opening. This space ensures that the fuel can expand when the temperature rises without overflowing the tank. If the fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the marked tank capacity.
