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

"When you give someone the option to cut emissions now, and also get 20% fuel savings, how does that not sell?"
- Tyler Cole, Director of Carbon Intelligence at FreightWaves
Decrease Fuel Consumption
Fuel Usage is reduced by 15%-30%, delivering significant fuel cost savings.
Reduce Harmful Emissions
An improved combustion process reduces harmful greenhouse gases. Diesel engines with a SPIER System exceed EPA 2028 emission requirements.
Improve Horsepower
The SPIER System uses a patented blended-induction process to deliver beneficial gases, boosting power.
Less Maintenance, More Uptime
Less contamination in critical engine systems means fewer breakdowns, lower maintenance costs and more uptime.
The SPIER System ensures that an abundance of thermally controlled useful gases are delivered to the cylinder inside the cylinders 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 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.
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 cylinders.
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.

All Conditions and Tests
Our results are fully supported by extensive research, proven science and thorough and independent testing.
Extensive testing of the SPIER System demonstrates consistent improvement in fuel savings and horsepower while simultaneously reducing harmful emissions. Tests have been conducted on both medium and large displacement engines, across multiple grades and terrains, with and without load, and with various wind speeds and wind direction. Tests have also been performed on multiple engine manufacturers and truck makes and models. In all tests, the SPIER System delivered predictable and consistent improvements when compared to baseline tests (when no SPIER System was installed).
Gas analysis tests were performed in conjunction with the Rochester Institute of Technology (RIT Case Study). The gas analysis tests confirmed a reduction of residual oxygen at the tailpipe and a reduction of harmful NOx emissions, resulting in an 18% improvement in MPG.

Less Maintenance, More Uptime
The SPIER System has a direct and beneficial impact on Maintenance Costs. Many costly systems need to be maintained less frequently, including:
-
EGR (Exhaust Gas Recirculation System)
-
DPF Filter Cleaning – reduced by 25%!
-
DEF and SCR systems are used and maintained less frequently.
-
Other costly repairs, including engine rebuilds, turbocharger failures, and engine fault codes are reduced or eliminated.
Less time in the shop means lower repair bills and more Uptime for your fleet!
Reduce harmful Emissions
Harmful emissions coming from a diesel engine have many harmful impacts, including negatively impacting our environment, and increasing the maintenance costs related to the equipment on your fleet. Again in 2028, the environmental Protection Agency has further tightened allowable levels of harmful emissions. The SPIER System improves the diesel combustion process and reduces harmful emissions. Vehicles with a SPIER System installed exceed EPA 2028 emission requirements today.
Improve Horsepower
The SPIER System directs beneficial gases to the cylinders of the diesel engine. Depending on driving conditions and the demand on the engine, the SPIER System optimizes the mix of these beneficial gases and makes the combustion process more efficient, improving horsepower.
Less Maintenance, More Uptime
Every long-haul trucker knows that the longer a diesel engine is running, the more soot builds up from Exhaust Gas Recirculation (EGR) that, eventually, will result in a huge maintenance bill. Unfortunately for drivers and fleet owners, often times this includes a catastrophic engine failure out on the road. Looking at examples from SPI.Systems Corporation’s testing and tear down of engines after as little as 100,000 miles provides a glimpse of just how damaging soot can be.
Why do we need EGR at all? Its purpose is to cool the combustion process to help meet emission regulations on oxides of nitrogen, called NOx. However, the soot particles at engine-out going into the EGR system are very sticky and immediately bond to each other, to intake plumbing and cylinder surfaces, and get into the engine oil. As soot particles thicken the oil, they cause turbocharger seizures and cylinder wear. The maintenance bill can go as high as $10,000 per year, driven by engine contamination alone, all in order to meet emissions standards.
Clearly, the cost of maintaining diesel engines is significant. Add in Diesel Exhaust Fluid (DEF) pumping and dosing of the final catalyst called Selective Catalytic Reduction (SCR). This final aftertreatment is also necessary to reduce the NOx that EGR misses. Its maintenance cost is also high due to contamination from urea deposits, so now maintenance of the total system becomes extreme, all because of NOx. What can the trucking industry do about it?
SPI.Systems has been working on reducing the costs of NOx reduction since 2018. Our new method is to attack the problem in two ways:
A) Reduce the percentage of EGR soot-laden exhaust reentering the engine.
B) Reduce the need for EGR valve opening by cutting NOx in combustion.
SPI has succeeded in making major improvements in combustion, along with reductions in soot damage. SPI has measured that success in road testing that included emissions and MPG measurements, along with DEF usage readings. Here’s what has been achieved with an upfit of the SPIER System on 15-liter engines:
-
Soot generation reductions from enhanced combustion up to 50%.
-
Oxides of Nitrogen (NOx) reductions at engine-out up to 20% = less DEF usage and less EGR.
-
Cleaner engine oil and cylinder walls = reduced engine rework and turbocharger failures, longer oil life.
-
Reduced need for DPF cleaning and longer time between active DPF regenerations.
-
Improved horsepower and grade climbing through more efficient combustion.
-
Reduced DEF system and SCR maintenance.
-
Lower maintenance and downtime costs.
-
MPG improvements of 15-30%.

Lower DEF usage = reduced EGR soot back into the engine. At last, there is a way to reduce the impact of “the engine killer.”
Save Big Money on EGR Engine Damage
Improve Fuel Economy
There is a direct relationship between reduction in EGR and improvement in fuel economy, since they are both influenced positively by the enhanced combustion produced by SPIER. Here’s a road test report by SPI which includes our tracking of both EGR and fuel economy according to the terrain variations on a given route and load.
