Engine cleaning / BEDI cleaning for full performance!

Recently updated on November 27, 2020 at 02:39 am

The problem with diesel engines in particular is that increasing pollutant emissions and consumption are ubiquitous. Regardless of the fuel used, the performance of all internal combustion engines decreases over time. And the engines are often clogged even with older gasoline direct injection engines. At some point it is time to have the engine cleaned thoroughly. But we don't just mean that any addition, but we mean a proper cleaning of the inner workings of the engine.

combustion residues in the engine

Every vehicle owner is able to do something for the longevity of the engine. Poor combustion and many cold starts, which are unavoidable in winter in particular, literally clog the engine. Soot particles accumulate on the cylinder walls and on the spark plugs, the emission of pollutants increases and the vehicle's performance decreases. Every car enthusiast's nightmare. For this reason, mechanics advise that the engine be cleaned at regular intervals in addition to the oil change to be cleaned. So, as the owner of your vehicle, you can devote yourself to the next emissions test with a clear conscience and do not have to live with a loss of performance. Experience shows that pollutant emissions can even be almost halved by cleaning them in some cases.

Furthermore, in powerful vehicles with around 400 hp, some +50 hp of lost power can be regained. And all this with lower consumption. Of course, this always depends on the vehicle type and the installed engine as well as the degree of pollution. But the improvements are repeatedly confirmed by vehicle owners in various forums who have made the decision to subject the engine to a cleaning. Engine cleaning is often recommended in combination with a consumption-reducing one ECO-Tuning. But even with a classic increase in performance, thorough cleaning in advance and at regular intervals in the following years cannot hurt.

What leads to engine pollution?

An engine cannot be compared to a sterile laboratory. Even the fuel carries the smallest particles with it. Abrasion, additives, tar, oil and resin are also welcome. So you can imagine how much contamination an engine accumulates in its entire service life. The TSI engines from Volkswagen are particularly criticized here. These sometimes tend to extreme adhesions. Almost all components that are close to the combustion area are affected. Starting with the throttle valve, through the valves, the cylinder head, the seals to the exhaust gas recirculation. A big drawback is that these parts are responsible for the performance of the vehicle.

Cost of a good engine cleaning!

The prices are almost always adapted to the engines. Logically, a normal four-cylinder costs less than a powerful twelve-cylinder or a V8. You can count between 150 and 350 euros for a good chemical engine cleaning, which is also worth it. For mechanical cleaning by hand with the engine disassembled, however, at least € 600 should be planned.

the process of cleaning the engine

Cleaning is very complex and involves several sub-steps. In order to loosen dirt in the fuel tract, the fuel is turned on Cleaning additive attached. This is best possible when the tank is about half full. To the Intake tract cleaning special equipment is then required that injects the cleaning mixture into the air flow in front of the throttle valve. Now the engine is started again and again at different intervals so that the cleaning mixture and the mixture for the intake tract are fed in and have time to take effect. For optimal cleaning, we recommend leaving the vehicle overnight in the respective workshop. This allows the cleaner to work optimally and improves the end result. If you cannot guarantee this for reasons of time, you often have the option of getting a replacement car. Since some of the cleaner is still in the fuel, cleaning will continue until the next tank of fuel. After that, fixed oil change intervals, premium engine oils and petrol with a higher octane should be refueled to maintain the condition.

essentially the steps of purification

It does not always have to be a cleaning, in which you have to partially disassemble the engine. A performance measurement can decide which type of cleaning should be carried out. If the factory performance still fits, then a dry cleaning may be enough. If not, harder methods are needed.

What actually is a coke?

The resulting oil mist from the crankcase ventilation and the hot exhaust gases from the exhaust gas recirculation ensure a permanent layer of oil carbon directly in the intake tract. But not only there, this layer also settles on the intake valves. With a turbo engine, the problem is less present due to the high boost pressure. And the modern engines with dual engine injection and intake manifold are hardly exposed to coking.

In summary, the most important information for cleaning the engine:

• possible for diesel and petrol cars
• Common designations: BEDI cleaning
• is used to remove combustion residues in the engine caused by unclean combustion and cold starts
• Cleaning removes soot from the cylinder walls, the spark or glow plugs etc. which are caused by abrasion, additives, tar, oil, resin etc.
• The amount of pollutants can be significantly reduced by cleaning the engine
• on average, between 5 and 10 hp can be "recovered", with powerful engines up to +50 hp
• fuel savings are sometimes achieved
• Engine cleaning can be carried out in combination with an ecotuning or a classic performance increase
• BEDI cleaning should include cleaning the throttle valve, valves, cylinder head, seals, pistons and exhaust gas recirculation
• optimal cleaning results are achieved in combination with an oil change
• BEDI cleaning procedure with cleaning agent: cleaning additives are added to the oil, which remove incrustations and build-up from the motor body, then the dirty oil is drained off and replaced, intake tract cleaning using special equipment (injects the cleaning mixture into the air flow in front of the throttle valve), engine is started at intervals, vehicle should be left overnight
• Prices for BEDI cleaning from €150,00 to €350,00
• Prices for manual engine cleaning from around €600

But what if the engine is not yet completely junk, but just runs out of round? Then maybe our contribution on the topic "uneven engine running" continue. We hope you the info report on the subject Engine cleaning (further names / keywords: BEDI cleaning, engine cleaning, coking) out of the area Tutorial wiki liked. Our goal is that the largest German-speaking tuning lexicon (Tuning Wikipedia) and to explain tuning terms from A to Z easily and understandably. Almost every day we expand this lexicon and how far we are, you can HERE see. Soon the next one will be Tuning scene concept be illuminated by us. By the way, you will be informed about new topics if you have ours Feed subscribe to.
