When it comes to old internal combustion engines, emissions are a problem for owners. A lot of work has been done to lower NOx and CO2. But investments have been either on pre-combustion or post-combustion technologies. Radical Combustion Technologies’ RCTClean™ Solution goes into the heart – the combustion Chamber, inside the cylinder. Fundamentally changing the Combustion Process itself means better burn, higher stability, lower emissions, higher horsepower and better fuel efficiency.
