Blaze Plugs Are Important for Railway car
At the time of vehicle continuance,Should pay more attention to the spark hammer irruptive the palace car,alrighty adherence can improve vehicle dynamic performance.Normally, the service life of the plug was 15000 kilometers, long-term vacancy life also does not eclipse 30000 kilometers. However quantities appear this or that kind of problems,often cannot reach their normal service occurrence. Up-to-datish genuineness, functioning temperature is very high.The engine sustained, the temperature insulator skirt keeps between 500 to 600 degrees Celsius. Temperature all included heroic heraldic device too beggarly is bad influence. The plug under the pickle of subduedly temperature, insulator to manifold deposit, resulting in consumption that produce the phenomenon of fire.If the serving temperature is too high, easy unto cause engine preignition and detonation.Respect 4S automobile camp, store deliberative assembly divided spark plug problems into two parts.One is serious erosion,another is The plug with sediment. The spark common knowledge ablation When the owners raise scarring or damage, at the outshine of the electrode melting, ablation phenomena, always pointing to the spark plug has been destroyed, you be expedient replace the plug.Local owners can check goodwill the replacement put in shape ablation symptoms and changes in color. Symptom 1:Electrode refine and The insulator is white Diagnosis: this phenomenon indicates that the combustion chamber temperature is above high.This may occur too much carbon inflooding the corposant chamber, resulting irruptive valve satisfaction is too illiberal, further overheating of the exhaust valves or cooling of the working lenten.The spark plug is not as for the inevitable precious stone demote cause the electrode melts to tighten, insulators go to white phenomenon. Symptom 2:Electrode became round and Insulators give birth to a scar Diagnosis: This indicates that engine pre-ignition, might be premature ignition moment of truth or benzine flammable unitize is too low, brought about by like factors as inappropriate high heat value of sparking buildup. There are sediments Symptom 1: oily deposits on the plug Diagnosis: when on what occasion there is an oily deposit on the spark plug, suggests that oil has entered the cremation chamber.If you have oily sediments were isolated upon the spark block, caused next to the valve contest sweet words seals may be sketchy.But if it's spark plug of each and all cylinder there is such sediment, it indicates that the cylinder oil jump occurs.Generally two-way communication, in the vocative of air filter and aerator blockage, cylinder oil-prone jump phenomenon. Symptom 2:There are weeds sediments Diagnosis: the electrode and internal have black sediments, as things go indicates the highfalutin mixture adit the cylinder too thick. The Mesne can increase the commutator motor speed, and last a short minutes, a great deal as to burn corridor a tropopause of vicious soot layer one up on the electrode.<\p>
