How to remove carbon dirty deposits from every part of the engine? That is a problem that all car owners have to face. We composed a detailed article to guide users through the best method of cleaning every part of the engine. Many people might be wondering if a spray carb cleaner can be used for air intake cleaning. We also give the answers as well as many other great methods to clean your engine parts more efficiently and effectively.
How to Clean Carbon Oil deposits in the Air Intake duct and intake manifold
Generally, car owners don’t pay much attention to the carbon deposits in this part, thinking that idling jitter and poor acceleration is OK as long as the throttle is cleaned. In fact, the more carbon deposits in the intake duct and intake manifold, the less precise the ratio of oil and gas mixture. It will result in an insufficient intake of air, poor acceleration, and soaring fuel consumption.
Therefore, the cleaning of the air intake is very important. In addition to dismantling and washing, the most effective way is to go to the 4S store to “sling”. The so-called sling is to use professional chemicals to connect to the engine through the disassembly-free cleaning equipment. The air duct will automatically bring the atomized chemical stock liquid into every corner of the air intake system as the engine is running. The cleaning rate can reach over 80%. If you think the 4S shop is too expensive to do this, you can go shopping online to buy a cleaning agent, e.g spray carb cleaner, to spray cleaning detergent into Air Intake and manifold.
How to Clean Carbon deposit in fuel Injector and Combustion chamber
These two parts are the simplest and can be solved with gasoline additives. However, there are also two situations we need to pay attention to. There are more and more direct-injection vehicles nowadays. We have to mention two things for these parts of the cleaning.
Direct injection (in-cylinder direct injection) models
The fuel injectors of direct injection vehicles are inside the combustion chamber, so fuel additives containing PEA (polyetheramine) are needed to clean the carbon deposits in the fuel injectors and the combustion chamber. PEA is a chemical composition that has excellent cleaning ability in the high-temperature zone (inside the combustion chamber). Most of the additives on the market are PIBA (polyisobutylene amine). Do not use this additive for direct injection vehicles. Using it will increase the carbon deposit in the combustion chamber. Because PIBA has almost no cleaning ability in high-temperature areas.
The current mainstream PEA products include TCP and red-line SI. If you don’t have money, you can buy Redtex with higher PEA content, mustard green, etc. Cleaning once every 5000 kilometers is OK.
Electronic injection (manifold injection) models
As the fuel injectors of electronic fuel injection vehicles are at the front end of the intake valve, the carbon deposits on fuel injection nozzles and intake valves of electronic fuel injection vehicles require PIBA (polyisobutylene amine) fuel additives to clean. As the chemical composition of PIBA has excellent cleaning ability in the low-temperature area (intake valve, injector, intake manifold), it does not have any cleaning ability in the high-temperature area (combustion chamber).
Fortunately, there will not be too much carbon deposit in the combustion chamber of an EFI car, unless your car burns engine oil. There are many brands of such additives, such as G17, Hailong, Haute, Kunlun Star, Red Dex, and Happy Running. There are many more, too much to count. EFI vehicles must use this small-package PIBA fuel treasure for a long time to ensure the cleanliness of the fuel system.
There are also some remedies, such as slinging a bottle (nozzle cleaner), foaming the interior of the combustion chamber, and so on. If it doesn’t work, remove the engine.
Three-way catalytic deposit
Generally, car owners don’t care about whether the three-way catalytic converter is dirty or not. What does the unqualified emission have to do with me? NO, it’s not good for you to do this. When your vehicle goes online to test the exhaust, you will be dumbfounded. Therefore, it is necessary to clean the three-way catalyst regularly.
Car owners can remove the three-way to give a bubble bath. Of course, they can also go to the 4S shop to “hit the bottle”. Similarly, if the 4S shop is too expensive, you can continue to go to a certain online shop and buy a three-way catalytic spray carb cleaner, and then finds a car dealer to hit the bottle. Although the cleaning strength is not as good as the disassembly and washing, it is more than enough to let you pass the exhaust gas detection.
How to Clean Sludge inside the engine
Many car owners think that after cleaning the fuel system, such as the throttle, intake duct, fuel injector, combustion chamber, and three-way catalysts, the vehicle can return to its peak state. In fact, it is almost the sludge inside the engine that is really terrible.
Generally speaking, there are two ways to clean the inside of the engine, the first is to use cleaning oil, and the second is to use the internal carb cleaner to spray into the engine. Cleaning oil is generally not easy to find. Because the freight is more expensive, online purchases are more disadvantageous, and you need to pay for the working hours of two oil changes. So the cost is relatively high.
The spray carb cleaner for the engine is OK, and the price ranges from $5 to $30 on the Amazon store. Many good internal carb cleaners do not contain the metal component of ZDDP, which will not harm the three-way catalysis. The lubrication and cleaning effects are very good. If you want to use a pot of good engine oil, you must clean the engine interior before maintenance.
