Fuel tank truck engine carbon deposition is the fuel and lubricants blow-by gas mixture of incomplete combustion generated after the sediment. (Mainly composed of hydroxy acids, asphaltenes, tar, etc.) The formation of sediments and the car's "fuel" and "oil" is directly related to: first of all because of the " Lubricating oil "of the blow-by gas contains carbon particles, in the incomplete combustion of a large number of deposition. Oil tanker itself contains colloidal, impurities, or storage and transportation process into the dust, impurities, accumulated over the years in the automotive fuel tank, into the tubing and other parts of the formation of similar sludge deposits; followed by gasoline in the olefins and other unstable Components in a certain temperature, the occurrence of oxidation and polymerization reaction, the formation of colloidal and resin-like sticky material. These sticky material in the nozzle, inlet valve, combustion chamber (cylinder head and piston top) and other parts of the deposition will become hard carbon deposition. In addition, due to urban traffic congestion, tankers often at low speed and idling state, will increase the formation and accumulation of these deposits. To put it bluntly, driving habits, bad oil, pay no attention to protect the tanker is the direct cause of the formation of carbon deposition.
2: Fuel tank truck engine carbon deposition hazards
To sum up, the fuel tank truck engine carbon deposition on the impact of the tanker is still quite large, the first is to reduce engine power, which is uneven and gradually reduce the power output, in other words is more and more powerless. Second, increase fuel consumption, increase your financial burden. Third, the cold start difficult, that is, difficulty in ignition, not easy to drive, and finally a serious combustion chamber will cause the cylinder knocking, low speed to accelerate the sound of the piston and the crankshaft damage, which seriously affected the tank Car safety. Then there is a row of ultra-standard, not only pass the annual inspection, but also directly increase the harm of environmental pollution.
Three: how to diagnose the fuel tank truck engine carbon deposition
In the fuel tank truck maintenance for the intake pipe carbon deposition diagnosis is very simple, as long as the throttle removed can clearly see the degree of carbon deposition. But the diagnosis of valve carbon deposition has always been a problem, usually with the help of some tools such as endoscopic diagnosis, like the hospital with gastroscopy in the same diagnosis of stomach.
In other words, the driver encountered in the driving speed is slow, urgent refueling tempering, cold start the phenomenon of difficulty, the fuel tank truck valve is likely to have carbon deposits. Found that idle low and idle when the car shaking, throttle when the card issuance, no idle after the battery change, then the fuel tank truck into the trachea has been very serious carbon deposition. With the above phenomenon should be promptly to the professional repair shop inspection.
