Does it really matter if the car pulls high-speed carbon?


Many small partners are very interested in the issue of carbon deposition. The first thing to say is that the carbon deposition of the engine is a normal phenomenon. All vehicles will have a certain degree of carbon deposition.

Is it true that the high-speed car can really clear carbon? In fact, the effect is not great. What is carbon deposition?

Carbon deposits are mainly caused by insufficient combustion of fuel in the engine, or paraffin waxes in gasoline that cannot be completely burned. They remain in the nozzles, throttles, oil lines, spark plugs and other components. Under high temperature conditions, Instead, it forms carbon deposits.

Accumulated over the years, leading to the launch of components can not work properly, there are difficulties in starting, idling instability, power decline, vehicle acceleration and other phenomena.

Carbon production In daily driving, there are many situations that can increase the formation of carbon deposits, for example:

1. Vehicles that idle for a long time at low speeds, travel at a low speed, travel within an ultra-short distance (within 10 minutes or 5 kilometers), and long-time hot cars in situ will cause insufficient fuel combustion into the cylinders, which will increase the formation of carbon deposits.

2. The poor cleanliness of low-grade fuel contains a lot of impurities. These impurities are themselves the main components of carbon deposition, and it will make the combustion less fully, which will increase the production of carbon.

3, burning oil will also cause carbon deposition, on this topic, onion brother will find time to say.

Carbon cleaning 1, cleaning the throttle, inlet carburetor cleaning agent spray throttle and intake, scrub, and some do not even remove the throttle, this method has a little effect, but Very incomplete. 4S shop may charge 80-100 yuan, in fact, in the repair shop does not even have money to do it for you.

2, "play bottle"

In fact, the “bottle” is loaded with pressurized atomized cleaning agent, and the cleaning agent is injected into the intake passage. “Solvent dissolving” reaction occurs with the carbon deposition in the throttle, injector, and other components. The engine rotates at a high speed and blows out the cleaned carbon deposit out of the engine.

It is worth noting that "dumping bottles" discharge cleaned carbon deposits through the exhaust system, but if the carbon deposition is very serious, it will cause clogging or even damage to the three-way catalytic system.

3, use "cleaning agent"

The cleaning agent is poured into a machine, pressurized by a machine and sprayed into the combustion chamber, so that the cleaning agent reacts with carbon deposition to dissolve, and then the waste liquid is drawn out.

It should also be noted that if the carbon deposition is very serious, if you can't completely withdraw the big carbon deposits, you may damage the combustion chamber.

4. Long-term use of fuel additives Clean fuel additives, although not as thorough as the role of propaganda, but still have a certain role, especially for non-direct injection models.

Now there are many effects of washing carbon deposits on the Internet. In fact, they are exaggerated. Although these things have a certain role, but there is no such exaggerated effect, but also depends on the quality and performance of the use of cleaning agents.

5, wash and wash If your car carbon deposition is more serious, then wash and wash is the most useful way to clear carbon, of course, is relatively more troublesome and more expensive. However, everyone does not need to understand it as an overhaul. In fact, the engine is cleaned by removing the intake manifold and disassembling the engine cylinder head. If the technology is good, it will not have any effect.

6, pull high speed can clean carbon deposition it?

In theory, at high speeds, the engine speed is increased and the amount of intake air is increased. A portion of the carbon deposit can be washed away. However, the actual effect is negligible, and it can only become relatively full of combustion, and it can relieve the effect of carbon deposition. It is not necessary to run high-speed in order to clear away carbon deposits.

At the end of the summary, it was emphasized that carbon deposition in the engine is a normal phenomenon and cannot be avoided. If the phenomenon is not serious, no special panic is required. Blindly doing some so-called cleaning projects is not only cost-effective, but may also damage the rest of the car.

The best way to “clean up the carbon deposit” is to take apart and wash, disassemble the engine cylinder head (not overhaul), and perform cleaning of various parts, although it is a little troublesome but it is thorough.

The best way to prevent carbon deposition is to develop a good habit of using cars to avoid prolonged idle or low-speed driving, short-distance driving, in-situ hot cars, and avoiding the use of inferior fuel.

Packing Machine
