Is it necessary to clean the accelerator for car maintenance?

Car maintenance needs to clean the throttle. Regular cleaning has five functions: 1, which can effectively clean and dredge the glue and carbon deposit of the fuel nozzle and keep the fuel system clean; 2. It can clean the waste gas circulation system, reduce waste gas emission and save fuel, thus effectively protecting the oxygen sensor and the three-way catalytic conversion device; 3. It can help prevent symptoms such as knocking, unstable idle speed and poor acceleration caused by colloid and carbon deposition; 4. It can eliminate the carbon deposit on the valve seat, lubricate the valve and valve guide, improve the sealing performance, restore the cylinder pressure and increase the power; 5. It can blow off the carbon deposit in the combustion chamber, lubricate the upper area of the cylinder, reduce the wear of the piston ring and prolong the service life.
