A safer, chemical-free approach to removing carbon buildup and restoring engine performance for fleet vehicles, dealership service departments, and municipalities.
Schedule Your ServiceModern gasoline and diesel engines are more advanced and efficient than ever, but that advancement comes with a consequence: internal carbon buildup. Direct injection, turbocharging, advanced emissions control systems, extended idling, and short-trip driving all contribute to carbon accumulating on intake valves, pistons, injectors, combustion chambers, and exhaust pathways.
As carbon builds, airflow becomes restricted, combustion efficiency declines, fuel economy drops, emissions increase, and internal components experience added strain. These changes often happen gradually and without triggering a warning light. Traditional maintenance addresses external systems but does not remove this internal carbon accumulation.
Can physically remove heavy carbon deposits, but it requires partial engine disassembly, creates vehicle downtime, and carries risk if not performed correctly.
Easy to apply but have limited effectiveness on hardened carbon; they can only reach areas where liquids can flow and can clog catalytic converters by breaking carbon into larger fragments that are forced downstream.
USA Carbon Solutions uses a proprietary, precisely controlled process that enhances combustion, allowing carbon to be converted and cleared naturally through the exhaust rather than forced downstream.
By working with the engine’s normal combustion cycle instead of introducing chemicals or mechanical force, carbon is addressed as part of standard operation—reducing the risk of downstream damage to emissions components.
The process is non-invasive, chemical-free, and performed without engine disassembly.
USA Carbon Solutions introduces a hydrogen-rich gas into the engine’s air intake while the engine operates at normal temperature. Hydrogen enhances the combustion process, allowing existing carbon deposits to be vaporized and expelled naturally through the exhaust.
In diesel engines, hydrogen-assisted combustion helps break down soot and carbon associated with high-compression, turbocharged operation—supporting cleaner combustion and more efficient exhaust flow without interfering with emissions hardware.
Every service includes a before-and-after Emissions & Efficiency Report, providing documented insight into how the engine is performing. The report captures key combustion and emissions indicators, helping verify changes in efficiency rather than relying on assumptions or subjective impressions.
Supporting California’s clean air goals through documented emissions improvement.
This reporting creates transparency and accountability, giving fleets, dealerships, and municipalities clear documentation of engine performance before and after service.

Regular carbon cleaning helps avoid expensive engine repairs caused by excessive carbon buildup.
For optimal performance, carbon cleaning is typically recommended every 3–6 months, depending on driving conditions, duty cycle, and engine type.
2018 Honda Accord Touring 1.5L
“I had a hydrogen cleaning and the gas mileage with my Honda has increased by 15%”
BMW Owner
“After the cleaning my BMW felt like the performance was restored.”
F650 Work Truck
“After the carbon cleaning on my work truck we noticed an immediate improvement in performance. We now have our entire fleet on a maintenance contract every 6 months.”
2017 Ford F-150
“My Ford F150 had a major repair due to carbon buildup. The bill was over $10k and in the shop for weeks. I wish I had known about this process before I went through the expense and hassle.”
2016 Mercedes-Benz GLA 250
“I couldn’t believe the difference. My car feels like it’s brand new! Highly recommend!”
