Our additive SUNRICHO –M12/FE120 has combustion catalyst this Combustion catalysts result in more efficient combustion of the fuel. The catalyst causes the fuel to burn more rapidly and completely yielding more energy from the fuel and higher pressure on the piston at the optimum crank angle in reciprocating engines. Reduced fuel consumption leads to a smaller carbon footprint even though the amount of carbon dioxide produced is the same. The difference is in particulate matter, unburned hydrocarbons and carbon monoxide. The result is lower emissions and reduced impact on the environment.
