"Cat fines"是燃油燃烧时会出现的一种附加物质,硅铝化物。
这东西低硫油燃烧时会产生的稍微多一些,重油 ...
In order to make petrol or other fuels out of crude oil, refineries work with the catalyst cracking process. So-called “cat fines” (including aluminum and silicon compounds) are used as catalysts and these are then found in the oil. The cat fines are extremely damaging to engines if the amount is too bigUsually we will enlarge the cylinder liner 0.1-0.2 mm on the biggest diameter at the same time the honing process will remove ovality and rapid diameter changes on your cylinder liner and restore the surface inside the liner to the engine makers specificationWe make spot checks in the cylinder liner with a special camera also we make replicas It is very important that the cat fines is removed from the fuel tanks before starting up the engine again |
