Combustion Technology Engine Cleaning Services

Carbon buildup is one of the biggest reasons diesel engines start losing power, airflow, and efficiency over time. When soot, oil residue, and wet carbon start stacking up inside the intake and EGR system, performance drops and problems start showing up fast.

Combustion Technologies SC101 is a non-foaming EGR and intake cleaner designed to clean critical components while they’re still installed on the vehicle. That means you can clean the system without tearing half the engine apart just to get the job done.

Unlike FC101, SC101 is built to penetrate and break down stubborn soot, oil, ash, and wet carbon buildup, restoring proper airflow through the system and helping the engine run the way it was designed to.

SC101 effectively cleans important components including:

• Swirl Flaps
• EGR Valves
• Intake Valves
• Throttle Bodies
• Pistons
• Turbo Vanes
• Turbo Actuators

By removing carbon deposits and keeping these components clean, SC101 helps restore airflow, improve engine efficiency, and maintain long-term performance.

If you want to keep your engine breathing right without tearing it apart, SC101 makes in-place cleaning simple and effective. 

When carbon buildup gets bad enough, sometimes the best way to clean it is by pulling the parts off and doing it right.

Combustion Technologies FC101 is a high-powered EGR and intake foam cleaner designed specifically for components that have been removed from the engine. It’s perfect for deep-cleaning parts during service or rebuilds where you want to get everything back to factory-clean condition.

FC101 attacks stubborn soot, oil residue, ash, and dry carbon buildup that collects inside the intake and EGR system over time. Its expanding foam formula penetrates deep into tight passages and hard-to-reach areas, breaking down deposits that can restrict airflow and hurt engine performance.

FC101 is ideal for cleaning components such as:

• EGR Valves
• Intake Manifolds
• Throttle Bodies
• Intake Components and Passages

By removing heavy carbon buildup, FC101 helps restore proper airflow through the intake system, improving engine efficiency and supporting long-term engine health.

When you’ve got the parts off and want them cleaned the right way, FC101 gets the job done.

Diesel engines take a beating over time. Fuel deposits, wax buildup, and carbon can start clogging up the system, hurting performance, fuel economy, and reliability.

Combustion Technologies CF101 is a full-spectrum diesel fuel and intake system cleaner designed to keep your engine running strong. Just one bottle treats up to 20 gallons of diesel fuel, working throughout the entire system to clean, protect, and improve overall engine performance.

CF101 helps lubricate the entire fuel system while cleaning injectors and aftertreatment sensors, helping restore proper fuel flow and combustion efficiency. It also breaks down wax deposits that can restrict performance, especially in colder conditions.

Cold weather can be tough on diesel engines, which is why CF101 also lowers diesel fuel gel temperature by up to 30%, helping your engine start easier and run more reliably when temperatures drop.

With regular use, CF101 helps:

• Clean fuel injectors and intake components
• Lubricate the entire fuel system
• Remove wax deposits that restrict performance
• Improve cold starts and winter reliability
• Lower diesel gel temperature by up to 30%
• Improve fuel economy by up to 8%

The result is a cleaner fuel system, better efficiency, and stronger engine performance.

If you want to keep your diesel running clean, efficient, and ready to work, CF101 gets the job done.

Modern diesel engines rely on the DEF system to stay compliant and running right, but crystal buildup inside the system is one of the most common causes of warning lights, derates, and expensive repairs.

Combustion Technologies DC101 is a powerful DEF system treatment designed to keep the entire system clean, efficient, and operating the way it should. Just one bottle treats up to 20 gallons of DEF, working through the tank and system components to break down existing crystal buildup while helping prevent new crystals from forming.

By stopping crystal buildup before it becomes a problem, DC101 helps reduce the chances of costly downtime and DEF system failures.

DC101 also goes further by cleaning and lubricating the entire DEF system, removing harmful sludge and bacteria that can contaminate DEF and affect system performance. It even lowers the DEF freeze point by up to 17 degrees, helping improve cold-weather reliability when temperatures start dropping.

In addition, DC101 reduces surface tension, helping improve DEF return flow back to the tank and supporting smooth, consistent system operation.

Benefits of DC101 include:

• Breaks down existing DEF crystal buildup
• Helps prevent new crystals from forming
• Cleans and lubricates DEF system components
• Removes harmful sludge and bacteria
• Lowers DEF freeze point by up to 17°
• Improves return flow back to the DEF tank

For best results, we recommend treating your DEF system once per month with DC101. If your truck goes through DEF more frequently, treating twice per month may be beneficial.

The photos shown demonstrate our own testing with DC101. The DEF readings confirm that DC101 does not negatively affect DEF quality, and the crystal test shows the difference between untreated DEF forming crystals versus treated DEF remaining liquid.

If you want to keep your DEF system clean and avoid the headaches that crystal buildup can cause, DC101 is a simple way to stay ahead of the problem.

Gas engines deal with the same problem every engine does over time — carbon buildup, fuel system deposits, and wear that slowly robs power and efficiency.

Combustion Technologies GC101 is an advanced gasoline engine treatment built to clean, protect, and improve overall engine performance. Just one bottle treats up to 20 gallons of fuel, working through the system to clean critical components including fuel injectors, fuel lines, sensors, and the fuel tank itself.

GC101 doesn’t just clean — it also boosts octane by up to 4 points, helping improve combustion and performance while reducing engine knock. At the same time, it adds important lubrication to the fuel system, helping reduce friction and wear on vital components.

This treatment also plays an important role in catalytic converter cleaning, helping remove carbon deposits that can restrict performance and fuel economy over time.

With regular use, GC101 helps:

• Clean injectors and fuel system components
• Increase octane for improved combustion
• Add lubrication to reduce friction and wear
• Support catalytic converter efficiency
• Reduce carbon buildup and harmful emissions

The result is better fuel economy, smoother performance, and a healthier engine overall.

If you want your gas engine running cleaner, stronger, and more efficiently, GC101 gets it done.

One Bottle Treats 1,000 Liters (264 Gallons) of DEF

Keeping your DEF system clean isn’t optional — it’s the difference between staying on the road or sitting on the shoulder waiting on a repair bill.

Combustion Technologies DC101 is built to keep your DEF system running the way it should. This powerful treatment breaks down and removes crystal buildup inside the system while helping prevent new crystals from forming in the DEF tank. That means fewer problems, fewer warning lights, and a whole lot less downtime.

DC101 goes beyond basic cleaning. It works through the entire DEF system to clean and lubricate components, remove harmful sludge and bacteria, and keep everything flowing the way it’s supposed to. It also lowers the DEF freeze point by up to 17 degrees, helping keep things moving when cold weather tries to shut you down.

On top of that, DC101 reduces surface tension, improving DEF return flow back to the tank and helping the system operate smoothly and consistently.

If you’re tired of dealing with DEF system issues, DC101 helps keep things clean, flowing, and working the way they were meant to.
