Who We Are
Clarke's DPF & Engine Specialists are Kent-based, independent specialists with years of experience in engine decarbonisation. We provide professional services using specialist equipment and detergents to restore your vehicle's performance.
Our team is trained to deliver the highest standard of service, treating each vehicle with the care and attention it deserves. We understand that your vehicle is essential to your daily life, and we're committed to getting you back on the road with improved performance and reliability.

What We Do
We use specialist decarbonisation equipment and detergents to remove carbon build-up from your engine, fuel system, and emissions components. Unlike quick fixes that simply clear warning codes, we treat the root cause by thoroughly cleaning carbon deposits, soot, and restrictions that cause poor performance, warning lights, and reduced fuel economy.
The process works by introducing a specialised cleaning fluid through your fuel system while the engine runs. This removes carbon deposits from critical areas including:
- Intake manifold and throttle body
- Combustion chambers and piston crowns
- EGR valves and EGR cooler
- Diesel Particulate Filters (DPF)
- Exhaust system components
- Fuel injectors and fuel system
Why Carbon Builds Up
Modern Driving Patterns
Short journeys and city driving don't allow engines to reach optimal operating temperatures. This leads to incomplete combustion and the build-up of carbon deposits and soot in critical engine components.
DPF & EGR Issues
Diesel Particulate Filters (DPFs) and Exhaust Gas Recirculation (EGR) valves are especially susceptible. Short journeys prevent DPFs from completing their regeneration cycle, causing soot to accumulate and eventually block the filter.
EGR valves recirculate exhaust gases to reduce emissions, but this also introduces carbon deposits that cause the valves to stick or become restricted. Over time, this build-up becomes severe enough to trigger warning lights and affect performance.
Our Approach
The Problem with Quick Fixes
Many garages simply clear warning codes or reset error messages. This doesn't fix the underlying problem – it just turns off the warning light temporarily. The carbon deposits, soot restrictions, and blocked components remain, meaning the symptoms will return, often within days or weeks.
Our Solution
We don't just clear codes. We treat the root cause by thoroughly cleaning carbon and soot restrictions from your engine and emissions systems. Our engine decarbonisation service removes built-up deposits, restores proper airflow, and allows your engine to perform as it was designed to – giving you improved MPG, restored power, and peace of mind.
