Environmental
Impact

 SPI’s approach to reducing diesel emissions is to employ a sustainable system of 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 to an unprecedented degree. 

Greenhouse Gases and the Carbon Footprint of Modern Diesel Truck Combustion

NO

X

Nitrous Oxide (N2O) (NOx): “Nitrous oxide 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.”

CO

2

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.

Proving Ground and Highway Testing

Collaborative engineering is a hallmark of SPI’s business model.  Therefore the most advanced academic and applications testing partners are engaged.

Here’s further evidence of SPI’s thoroughness in achieving optimum vehicle performance.

 

Research

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

 

Performance Monitoring

Sometimes customers will request intensive analysis of long-term performance data, along with explanations for variations.  Here’s an example of such a study by SPI.
