Importance of Cleaning Injector

As a key component of electrical ejection engine, injector has direct influences on the performance of engine. Injector blocking affects vehicle. The reason causing blocking is that carbon deposition inside engine deposits on injector or impurities in fuel blocks the access of injector. When vehicles have been driven for a period of time, fuel system forms certain sediments.   

 

Sediments forming is directly relevant to the fuel in vehicles. First of all, gasoline contains colloids, impurities. Or it may also include dusts or impurities during storage and transportation. Then, sediments like sludge are formed in fuel tank or oil inlet once for all. 

 

Secondly, unstable ingredients in gasoline react under certain temperature, forming colloids and resinoid dopes. When those dopes are burning at injector or inlet valve, sediments form tough carbon deposition. 

 

Besides, due to urban traffic jam, vehicles are always at a low speed or idle speed, which enhance the forming and accumulation of sediments. Sediments in fuel system have large harms. Sediments can block the needle valve and valve port on injector, having influences on performance of precision parts on electric injection system, causing power decline; sediments form carbon deposition at inlet valve which cause imprecise off, causing unstable idle speed, oil consumption growing with exhaust emission deterioration; sediments cause hard carbon deposition on piston top cylinder head. Because of high thermal capacity while poor thermal conductivity of carbon deposition, knocking and other obstacles may be caused easily; moreover, sediments can also reduce service life of three-way catalysts.

 

So, injector should be cleaned on time. No cleaning or frequent cleaning has bad influences. When to clean injector should depend on vehicle conditions and quality of fuel. In general, injector should be cleaned after vehicles having run for 20,000~30,000 km. It can be extended to 40,000~60,000 km for good vehicle conditions and quality of fuel.
