Description
Technical field
The present invention relates to pretreatment of metal surface technical fields, and in particular to a kind of side removing automobile combustion chamber carbon distribution
Method.
Background technology
In recent years, as the fast development of China's economy, living standards of the people are gradually increased, the family for possessing automobile is more next
It is more.With the increase of the mileage and the time limit of vehicle traveling, just will appear after petrol engine runs 30,000 kilometers or after 2 years
A kind of substance of the dirt and resin-like of viscosity.These substances can gradually increase, deposit, and then lead to the fuel combustions such as gasoline not
Completely, the generation of carbon distribution is further aggravated.
Carbon distribution be automobile engine during the work time, unsaturated olefin and colloid generate at high operating temperatures in fuel oil
A kind of substance of deeply worried shape.The maggot of automobile carbon deposition such as shank annoyings always every car owner, it constantly corrodes the heart of automobile
It is dirty --- engine allows automobile fuel consumption to increase, power weakens, ignition difficulties and Idling wobble.Automobile carbon deposition is all the time all
Generating, at the same also at every moment automobile is lost.Carbon distribution can be gathered in each position of engine, such as intake and exhaust system
System, combustion chamber, atomizer etc..When combustion-chamber deposit is serious, combustion knock, slow-speed of revolution acceleration can also be caused to have sound, right
Piston and bent axle damage, or even may finally lead to engine burn oil and be damaged.
Currently, the sweep-out method of carbon distribution mainly has：Physical removal method strikes off the carbon distribution on engine, and such method is very
Difficulty is clean by carbon cleaning, and easily forms cut in metal surface, and efficiency is low, and cleaning is complicated；Chemical cleaning method,
Mainly engine is impregnated by chemical agent, that is, utilizes 1%~10% 741 detergent, it is prolonged to impregnate, generally
It controls more than for 24 hours.But some stubbornness carbon distributions can not be thoroughly removed in this way, can only be polished by local mechanical, if adopted
It is operated with this, and is easy to damage matrix, cause scrapping for part.Metal watch of the majority chemical to engine itself at present
There is certain corrosivity in face, and such cleaning agent is poisonous and harmful irritant, inflammable and explosive, can seriously endanger the strong of operating personnel
Health, and serious pollution can be caused；Gasoline adds agent：Addition promotes the additive of burning in the oil, and gasoline is made fully to burn,
This method can effectively pre- anti-carbon deposition generation, but for have carbon distribution eradicating efficacy unobvious.
