In daily use, diesel oil from regular gas stations must be selected, and diesel oil that meets the temperature standard shall be selected according to the local temperature. Fuel quality is very important to engine performance and service life. This article will summarize the damage caused by inferior diesel to excavator and the methods of identifying inferior diesel for reference only.
The use of diesel engine will cause damage
1) Cause abnormal wear of fuel pump and fuel injector.
2) The needle valve of the fuel injector is stuck and the electric signal transmission is not accurate, resulting in inaccurate fuel injection quantity and oil dripping. At least, the speed limit of the vehicle is blocked, and at worst, the excessive fuel injection quantity leads to the dissolution of the piston and serious damage to the engine.
3) The diesel filter element is blocked.
4) Cause high temperature in the cylinder, piston crown melting, cylinder knocking, etc.
5) Cause insufficient engine power and abnormal smoke color.
6) Cause abnormal carbon deposition in the engine and wear the piston, cylinder liner, piston ring, etc.
7) It causes the early deterioration of engine oil, the decline of lubrication capacity, and the early wear of engine.
2. How to identify inferior diesel
1) Look at the color. Generally, high-quality diesel oil for vehicles shall be colorless, light yellow or light brown transparent liquid without turbidity.
2) Smell the smell. High quality diesel oil tastes normal. Inferior diesel oil has pungent or tasteless smell, that is, there is no diesel smell or the diesel smell is very light, such as recycled oil with peculiar smell or fishy and spicy smell, which may be refined from old tires or waste oil. Apply diesel oil and rub your hands quickly in the palm of your hand. High quality diesel oil has only oil smell, while poor quality diesel oil has pungent or no oil smell.
3) Try your hand. High quality diesel oil has low hand feel and viscosity. If it feels too thick, it is inferior diesel mixed with other lubricants.
4) Look at the smoke. Poor quality diesel fuel has heavy smoke color, which will choke the nose and smoke the eyes, resulting in direct flow of tears. High quality diesel fuel does not have this phenomenon.
