SPI’s approach to reducing diesel emissions is to employ a sustainable system of reactive gases, water vapor, and oxygen recovery from diesel exhaust. Those gases, currently being wasted, work to very significantly improve combustion enough to cut carbon dioxide and pollutant emissions (NOx) to an unprecedented degree.
Greenhouse Gases and the Carbon Footprint of Modern Diesel Truck Combustion
“Nitrogen Dioxide(NO2) occupies a relatively small share of global greenhouse gas emissions—about six percent—but it is 264 times more powerful than carbon dioxide over 20 years, and its lifetime in the atmosphere exceeds a century.”
Carbon dioxide (CO2 ): “is responsible for about three-quarters of emissions. It can linger in the atmosphere for thousands of years.”

By initially focusing corporate resources on the top three producers of greenhouse gases, SPI is committed to making a major contribution to improving the environment.

Here’s further evidence of SPI’s thoroughness in achieving optimum vehicle performance.
A key feature of SPI’s product and systems development is assessment of real-world applications of various technologies vs. those to be included in SPI’s designs.
Here we see analysis of improvement in Particulate Matter (or soot) generation in diesel combustion.
Current Technology: Engine-out PM (soot), noxious gases & acids directed back into the cylinder via Exhaust Gas Recirculation (EGR).
Tailpipe cleansed exhaust inducted back into the cylinder by the SPIER SYSTEM.
SPIER cuts the soot, gases and acids re-entry to the engine from the EGR system, visible in the EGR crossover
Long-Term Case Studies
SPI backs its final release testing with optional case studies of vehicle performance over extended periods of actual usage.
