How much is it to clean the throttle of BMW 3 Series?
When the engine is running at low speed, due to the small throttle opening, small air intake (small flow) and some very fine dust (not filtered by the air filter), the exhaust gas discharged from the engine valve chamber will be deposited on the air intake of the throttle and the idle speed control valve, resulting in slow throttle response (actual air intake reduction) and unstable idle speed. The computer controls fuel injection through the signal sent to him by the throttle potentiometer. Generally speaking, the electronic throttle is still relatively accurate. With the constant change of throttle opening and fuel injection quantity, when there is carbon deposit on the throttle plate, its air intake will also change. If it is different from the computer instruction, it will lead to easy flameout.
Five functions of regular cleaning: 1. It can effectively clean and dredge the glue and carbon deposit of the injector and keep the fuel system clean. 2. Reduce tail gas emission and save fuel, thus effectively protecting the oxygen sensor and the three-way catalytic converter. 3. It helps to 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 remove the carbon deposit in the combustion chamber, lubricate the upper part of the cylinder, reduce the wear of the piston ring and prolong the service life.
