Are you worried by looking at that thick black coating on your engine? Then this article will get you through all the details about preventing carbon buildup.
If you're wondering how do you reduce carbon build up in an engine but you're just swimming into the sea, then worry not! We've got you covered. Stick to the article, you surely will get your ultimate solution.
All about carbon buildups
If you ever see the pot on the high flame of an open stove, then you will easily get what is carbon build up. The carbon particles of the fumes of that burning wood create a coating on that pot.
In that same way injection vehicle engines also face carbon buildup due to fuel burning. Preventing that should be the main concern to save the engine.
What is the reason behind carbon buildup in engines
To know how to prevent carbon buildup in diesel engine, you have to have a clear idea about what causes carbon buildup in engines. Here are some of it:-
PCV
The smoke inside the combustion chamber went through the gap between the pistol ring and sleeve. Because of PCV the blow by returns to the engine wall and create the residue.
EGR
The direction of exhaust gas is rotated towards the intake manifold. Because of that all the carbon present in burned gas deposits on the engine’s wall.
Oil leakage
If the seal of the wall is leaked, then the oil sits on the top of the intake valve and starts building up carbon.
How to prevent carbon buildup
To keep your vehicle safe and sound from premature destruction, pick preventing carbon buildup than fixing it later. Here are the ways to do that:
Changing oil
Read the manual carefully to know the routine for changing the oil of your specific injection vehicle.
Choosing the right oil
The oil is basically 80℅ oil and 20% additives. Choose a good oil as both the percentages work in forming carbon residue.
Oil with an incorrect molecular structure can easily leave carbon deposits because of high temperatures. Here are things that you need to be careful about molecule:
- Good flow characteristics at low temperature
- Won't evaporate
- Won't break down
- Not overly large
- Not overly small
- Without the full hydrogen saturation
- Without overly long straight chain
Replacement of spark plug
The manufacturing company recommends a time limit for the replacement of the spark plugs. To avoid carbon residue, you have to replace it with a new one.
Cleansing the fuel injector
Try to find the best engine carbon cleaner. On the other hand, you can clean it without spending money on expensive cleaning machines. Here are the steps for this:
- Firstly, detach the O-rings from both ends of the injector.
- Measure the fuel head width.
- Purchase the same size rubber hose as the injector.
- Slide the rubber hose head on the fuel injector.
- Put the clamp on the hose for tightening.
- To make a path from the rubber hose to the crab cleaner pipe, use some other smaller size hose.
- Then you have to use marine shrink tubing in between that'll shrink up and go around the wires for the water, moister, and oil protection.
- Heat that. Then the shrink tubing will become smaller gradually.
- Protect the cleaner can's pipe with a tiny shrink tubing.
- Wait for 15 min to for cooling. Press the head for supplying crab cleaner to the fuel injector.
- Attach two alligator clips to the fuel injector to ground it one with the power source. For activation tap the battery porch with the other one.
Checking for carbon build-up and its symptoms
Be aware of all the carbon buildup in engine symptoms to know how to check for carbon build up. Symptoms and check-up routine is below:
Check up the signs | Symptoms to look for |
|---|---|
Read any problematic codes | Feels the lack of power |
Keep an eye on the timing of the valve | Less acceleration recorded |
Do a vacuum examination from lower to 2000 rpm | Decreased fuel efficiency |
Do a leakage test for the cylinder. | Low speed of engine judder |
Check the blow-by | Witnessed Cold stalling |
How to fix carbon build up in the engine
- First, you have to dismantle all the parts like the muffler, batteries, to prevent cylinder access blocking.
- Then, lift the cylinder off and detach the old gasket.
- Keep the valves closer and start scrapping the cakey residues using a wooden or plastic scraper.
- If the stubborn build-up still won't go, then look for a wire brush or putty knife to scrap that off.
- For cleaning away the leftover carbon coating dip the parts into any solvent what dissolves carbon deposit.
- Open each valve after. Then get rid of any visible carbon build-up.
- Check the cylinder head and engine block for not missing any carbon deposit.
- Lastly, attach and tight all the parts that you took off before.
StepS for removing carbon build-up
Here are all the steps that you have to follow and all the things that you need to be careful with.
What you need to follow | Things you need to be careful about |
|---|---|
Disassemble all the parts | Only detach those parts that resist the way to the cylinder |
Take of the cylinder | Keep the cylinder head loose for taking it off |
Remove the old gasket | Don’t save it just throw the old gasket away |
Start gentle scrapping | Use a wooden or plastic scraper for that |
Use solvent | Wear safety gloves to keep your hands protected from the hard solvent |
Look For Every Corner For Build-Up Residue | Don't miss out on the tight spot |
Reassemble all the parts | Don't lose tiny bolts, nuts, or batteries during reinstalling |
Final verdict
For the protection of injector vehicles preventing build-up is important. It'll not only reduces the rate of emission and noise but also increase the lifetime of an engine.
That’s why you should know what causes excessive carbon buildup in engines for prevention.
