Combustion Engine
Emission
Though instrumental in driving societal advancement for over a century, 4-stroke combustion engines pose a significant environmental challenge. Their operation releases a multitude of harmful pollutants, including nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter. These pollutants are linked to a variety of detrimental health effects, including respiratory problems, and contribute to environmental issues like smog formation, acid rain, and climate change. Mitigating combustion engine pollution is crucial to safeguarding public health and ensuring a sustainable future.
The Dynamic Flow engine technology offers superior emission control with its internal infinitely variable EGR system, which benefits both gasoline and diesel fuel engine:
Gasoline Engines: The Dynamic Flow engine offers the potential for a drastic reduction in carbon dioxide emissions, contributing to cleaner air and a reduced environmental footprint.
Diesel Engines: For diesel engines, the technology has the potential to significantly lower carbon dioxide, nitrogen oxide, hydrocarbon, and particle matter emissions.
