Is it useful to clean the intake throttle?
Improve the combustion efficiency of the engine and restore the strong power of the engine.
Reduce engine fuel consumption and automobile exhaust emissions.
Eliminate the formed carbon deposit and delay the deposition of new carbon deposit.
Improve the stability of the engine and make it run more quietly.
Extend the service life of the engine and reduce the comprehensive maintenance cost.
Remove carbon deposit and improve the accuracy of air intake and fuel injection.
One of the overall quality characteristics of China's fuel is its high content and poor stability, which is easy to oxidize and condense in the engine fuel system, resulting in gum and deposits: gum and deposits will block the fuel injection hole of the electric nozzle (the diameter is only 1-2 microns, which is thinner than human hair), and gum \ deposits are deposited on the valve seat, which is easy to generate hard carbon deposits when burning in the combustion chamber, and the valve oil seal is poor. Will lead to oil infiltration. After the engine oil is burned, carbon deposits will be formed in the combustion chamber and valve. If the fuel containing oil and water is added to the car, the combustion temperature will be lowered due to the existence of water when the engine is working, and the fuel oxidized at low temperature will lead to carbon deposition. In addition, the fuel with insufficient combustion will continue to evaporate and oxidize, and some soft black carbon deposits will be produced in the intake pipe (especially behind the throttle). These colloids/deposits and carbon deposits can lead to:
Blocking the needle valve and valve hole of the injector, resulting in a decrease in power performance.
Improper closing of the intake valve leads to unstable idle speed of the engine, increased fuel consumption and deterioration of exhaust emissions.
Hard carbon deposits formed on the piston crown and cylinder head are easy to cause engine knocking.
The structure of carbon deposit is similar to sponge, which will absorb part of the fuel injected into the cylinder, so that the concentration of the mixed gas that really enters the cylinder will be diluted, which will aggravate the problem of carbon deposit.
When the wall of the intake pipe becomes rough, the intake air will generate vortex in these rough places, which will affect the intake effect and the quality of the mixture.
Block the idle passage, so that the idle control device is stuck or beyond its adjustment range.
Shorten the service life of three-way catalyst and oxygen sensor.
During the operation of EFI engine, part of the exhaust gas generated by the combustion of combustible gas in the cylinder will pass through the intake valve, and the intake pipe will produce carbon deposit at the throttle body. After the engine is turned off, the oil and gas in the intake pipe will be cooled into liquid and deposited in the throttle body. In addition, after the air passes through the air grille for a long time, unfiltered air impurities will remain in the throttle body, which will lead to fouling for a long time.
The switch resistance increases, and the engine idling is unstable.
When it enters, it will produce eddy current and air resistance.
Low-speed throttle is difficult to control and cold start is difficult.
The computer transmission signal is lagging behind, and there is an error.
Engine anti-pollution alarm
Periodic cleaning of the three-way catalyst can:
Improve tail gas emission and activate three-way purification function
Improve fuel atomization performance and reduce engine fuel consumption.
Improve fuel combustion efficiency and restore power.
Improve cold start ability and prolong ternary service life
Therefore, in daily use, it is generally recommended to clean the nozzle every 30,000 kilometers.
Cleaning the throttle valve, intake pipe and three-way catalytic converter regularly is usually once every1.5-20,000 km.
