Innovative, Patented Technology

SPI.Systems Corporation invented and sells the SPIER SYSTEM™ which cuts fuel usage, reduces greenhouse gases and soot, while increasing engine power to an extent never-before achieved. These results exceed regulations for 2024 and the decade ahead.

The system will work on any modern diesel anywhere in the world and is immediately available at low cost per vehicle compared with other systems.

OUR MISSION—Meeting the world's needs for immediate action in creating easily-implemented, economical improvements in diesel performance & economy.



The SPIER System

The SPIER System™ is a proprietary dual induction system that revolutionizes the performance of diesel engines.





Reduced 15-20%

Particulate Matter Reduced 30-50%

Unburned HC's Reduced 100%

Combustion Efficiency Improved 15-35%

The result of the activity of the SPIER SYSTEM is a release of heat energy in the fuel that is far higher than any other system for enhancing diesel combustion that was ever thought to be possible (+9,455 KJ/MOL).

The SPIER Technology

The SPIER System combines complex chemistry, controlled flow rates and new concepts in thermodynamics to revolutionize the diesel combustion process. 

The SPIER System ensures that an abundance of thermally controlled useful gases are delivered to the flame front inside the cylinder of the engine.  By properly controlling and directing these gases, optimal combustion is achieved. 


Compared to today’s induction process, which is burdened by too many residual contaminants, the SPIER System creates the conditions where nearly complete combustion can occur. The SPIER System is a blended induction process that uses treated exhaust and combines it with inlet air. This process prevents inadequate and improper mixing of gases, and also eliminates thermal throttling caused by high EGR temperatures.


Research shows that residual oxygen for optimal diesel combustion is approximately 8%. Test results on diesel engines using the SPIER System show an 8% residual oxygen level, which translates into a 15-30% improvement in fuel economy.


Cost Effectiveness

SPIER reduces costly contamination of the emission control system and associated aftertreatment, reduces the load upon the EGR and SCR systems due to lower NOx levels, cuts oil contamination and cylinder wear, and cuts fault codes caused by faulty sensors and turbocharger failures.

No Emission System Alterations

Our system does not change the emission controls or electronics.  Emissions and fuel economy both improve.


Beneficial Gases are Recirculated

Cleansed exhaust is re-used and brought to the flame front.

Optimal Combustion

Chemistry and new thermodynamics create a uniquely efficient diesel combustion process.


Cleaner Engine/Cleaner Exhaust

Current carbon footprint of combustion is altered to reduce soot contamination of the environment and

to protect the engine from soot damage.
