Is it really useful for "bottle pump" cars to remove carbon deposits?

It has some uses: but it can't be completely removed.

Let's talk about what is called "infusion bag or bottle" first. Similar to the medical infusion bottle, technicians use the infusion bottle to input chemical cleaning agent to the throttle and air intake of the automobile to achieve the effect of removing carbon deposits. There is also a method of hanging bottles, that is, connecting them to the oil pipe of the engine and cleaning them with cleaning agent as fuel.

Now you must have a simple concept of carbon deposit and hanging bottles. So how to determine whether hanging bottles can remove carbon deposits? In order to let netizens see the changes intuitively, I took apart the engine directly to verify the situation of hanging bottles to clean up carbon deposits.

Test vehicle

After disassembling the engine, it needs to be reinstalled. Generally speaking, the carbon deposit of this antelope is not too much for an old car with 10 or above, and it can even be called very little, which is not unrelated to the owner's diligent maintenance and good driving habits.

After the engine is installed, the process of preparing to hang the bottle will begin. It is worth mentioning that there are some differences in the process, equipment and cleaning solution of hanging bottles all over the country, but the principle is basically the same as that of cleaning solution. The result of this experiment can only be explained by the operation method, equipment and cleaning agent of this experiment. (Hanging bottles to clean up carbon deposits mentioned in this paper is only for vehicles with manifold injection engines, and direct injection engines are not included in this discussion. )

Dismantle the machine for the second time after falling, and the overall feedback effect is good.
