The relationship between clogged fuel injectors in electronically fuel-injected vehicles and fuel quality
Thread Content
I urgently need the guidance of all experts. In Beiben tractors equipped with electronic fuel injection systems, clogging of the fuel injectors has occurred after using C3-standard Puchai diesel; is this related to the quality of the diesel used? If so, which diesel parameters should be checked? http://bbs.hcbbs.com/static/image/smiley/default/dizzy.gif
Diesel test parameters: Sulfur content: 0.033, kinematic viscosity: 4.2, flash point: 64, cetane number: 52, density: 0.81, boiling range: 10%: 199, 50%: 260, 90%: 331, 95%: 352. Acid value 0.5, copper corrosion: 1
Also, test the olefin content of the diesel again, or determine its bromine value. When the content of unsaturated hydrocarbons in the fuel is high, gums and various polymers are likely to form, causing blockages at the fuel injectors. It is not evident from the boiling range that diesel is heavier.
It might be that the ester content is too high! ! ! ! ! ! ! ! ! ! ! ! !
The acid value is 5, and this issue occurred only with one company’s oil from the same batch; it’s definitely our oil, not anyone else’s. I don’t understand what’s going on.
However, the sulfur content is 135; I’m not sure if that’s the reason
Oil coking is not related to sulfur content, but it is related to olefin and nitrogen content. The higher the degree of unsaturation, the higher the nitrogen content and the greater the gum content, which is key to coking.
Thank you, I’ve learned it: handshake
