Dr.QMAX Water Base Carbon Cleaner as “DQWBCC” solution eliminates carbon deposits inside the engine. It cleans the piston rings, allowing them to operate more smoothly. It also evens the compression pressures of each cylinder, and prevents not only lifter and tappet noises but also various other unwanted engine noises that normally result from a lack of oil circulation.

DQWBCC solution also removes the carbon that formed in the throttle body, spark plugs, intake and exhaust valves, the EGR valve, the catalytic converter, and muffler. You will soon see your dirty black muffler transformed into a clean muffler with a reddish shade. The reddish color of the muffler comes from the slight rust on the surface, which is formed in the process of large amounts of water being exhausted through the muffler. The water indicates that the combustion process inside the cylinder has become stable and the rings are operating effectively and the compression pressure has risen to normal.

Meanwhile, the moisture formed as a result of condensation inside the engine can have a detrimental effect on the metal surface and cause component failure. The process of wear will continue and eventually cause discernible engine noise.

* Recommendation for regular Carbon Clean / Maintenance service: every 20,000KM to 40,000KM.

Carbon deposits and sludge in intake manifold & combustion chamber

Carbon in intake manifold, valve, ports and reduce air intake efficiency

Too much carbon deposits in intake manifold and combustion chamber will leads to
· Loss of engine power
· Higher fuel consumption
· Reduced braking efficiency
· Increase cost of repairing
· Engine knocking and hesitation symptom
· Increase harmful emission to environment

With the assistance of unique machine Dr.Qmax Water Base Carbon Cleaner is able to remove carbon deposits from intake manifold, valve, combustion chamber, and exhaust.


· Restore engine power
· Fuel saving
· Improves braking efficiency
· Reduce the cost of repair
· Eliminates engine knocks and hesitation
· Reduce discharge of black smoke
· Increase the burning efficiency of combustion chamber

Why diesel engine discharge black smoke?
Black smoke is cause by the incomplete combustion of diesel.
There are 3 main factors that cause the incomplete combustion of diesel fuel.

1) Problem encounter in the fuel supply system
2) Problem encounter in the engine mechanism
3) Air intake system or exhaust system is not smooth

Conventional way of removing Carbon Deposits

1) Costly
2) Labour intensive
3) Time consuming
4) Can only be performed by experienced mechanic

Advantages of the New Technology Dr.Qmax Water Base Carbon Cleaner

1) Value for money
2) No need to dismantle engine head or others part
3) Fast (around 20 min to 30 mins)
4) Easily performed by ordinary mechanics
5) Safe and effective
6) Can be easily accepted as a regular maintenance service of intake manifold and combustion chamber

Dr. Qmax water base carbon cleaner Instruction (For Diesel, Petrol, and NGV engine)

Step 1: Start the engine and warm up around 5 minutes. 

Step 2: Adjust and make sure the engine rotational speed at 1800-2000RPM by using custom made accelerator paddle adjuster.

Step 3: Open de-carbonizer cover and fill-up with carbon cleaner into the tank and then close back the cover.

Step 4: Connect the compressed air into de-carbonizer intake valve and make sure the air pressure for both air input and output pressure gauge at 70 PSI.

Step 5: Insert the spray nozzle of de-carbonizer face to the throuttle body or carburetor.
(Precaution: don’t touch to the throttle body butterfly)

Step 6: Switch on the air compressor and open input valve, slowly open output valve until the RPM to 1500 and stay put.

Step 7: Carbon cleaner start flow in and spray into the intake valve or carburetor.

Step 8: The intake manifold will become cold around 3 minutes later (Injection engine only)

Step 9: Close the input valve and take off the compressed air supply, stop the engine after 5 minutes de-carbon are finish.

Step 10: Remove the spray nozzle and fix back the rubber hose to the intake valve.
