ROCHESTER, NEW YORK, SEPTEMBER 13, 2021 Damien Baker operates Ol’ Sckool Trucking, Ltd. from the mountains of western Pennsylvania. He runs to California, Washington state, and Wyoming about every other week, pulling 40,000 - 80,000 pounds. Along with his father, Mike, he schedules the loads and does all of his own maintenance on his Kenworth W990. Damien chose the Cummins X15 power option to get his deliveries done over some very severe terrains. He’s always seeking an “edge” with new technology to cut costs. As he says, “The little guy always needs an edge.”

After reading a recent trucking magazine article about a new retrofit system for diesel engines, Damien contacted the inventors at SPI.Systems Corporation about their patented SPIER SystemTM, which stands for SPI Exhaust Reaction. He immediately ordered the parts and scheduled the one-day installation with SPI.Systems.

The SPIER System is a combination of exhaust plumbing and “dual induction” of a portion of the tailpipe exhaust back into the engine cylinders. The chemical engineering of this new approach does the work of releasing enormous alternative energy in the combustion process, which decreases fuel consumption and harmful emissions, allowing truckers to meet and exceed U.S. emissions standards through the year 2027 and beyond. There is no interaction with or alteration of OEM systems on the vehicle. An added benefit is lower soot levels inside the engine, which cuts maintenance costs and reduces the need for exhaust aftertreatment solutions.

It didn’t take long for Damien to see the benefits of SPIER. He keeps detailed records, tracking MPG for fuel and DEF refills, both of which indicate significant cost reductions. A 30% reduction in DEF indicated reduced oxides of nitrogen (NOx) being generated in the engine and therefore reduced activity of both Exhaust Gas Recirculation (EGR) and Selective Catalytic Reduction (SCR), as explained below.

As an example of the teamwork between SPI and Ol’ Sckool, weekly reports on routes travelled and liquids added are tracked and graphed by SPI to provide insight into the effects of loads AND terrains for each delivery run. The illustration below shows a typical report:

SPI also generates MPG and DEF profiles by using its algorithm that includes adjustments for terrains and terrain durations vs. loads. In this example, Ol’ Sckool improved MPG by 29% using SPIER. At that percentage along with the 30% DEF reduction, Damien will save thousands per year and pay off his investment in SPIER in less than a year.

SPI maintains a history file of the tracking being performed for Ol’ Sckool. It is summarized below to reveal the improvements in operations that are important for any trucker:

· MPG improved by 29.7% to 6.11 mpg vs. comparable terrains OEM of 4.71.

· NOx at engine-out was reduced by 27.4% to 575 ppm.

· EGR activation was reduced by 30 points to only 27% open.

· DEF usage reduced by 30%.

· Power improvement of 7%.

The savings in fuel expenditures are easily calculated for the terrains and miles covered. The reductions in NOx and EGR benefit Ol’ Sckool in reduced maintenance costs due to less carbon contamination from EGR. That potential is evident in the reduction of the need for DEF dosage in the aftertreatment of the SCR system. Power improvement is derived from the Cummins INSITE readings, which define torque and RPM output for every second of operation, which SPI ran for Damien.

The rigging of Damien’s truck was performed with SPI engineers on location to provide tips on all the features of SPIER. Damien and Mike rigged the truck in short order and SPI participated in the road test. Overall result: instant recognition of a power boost of 7% and confirmation of the fuel savings. Damien now has the “edge” he was looking for.


Exhaust drawn from the tailpipe is routed to the Ejector (shown above), and then introduced into the intake. The SPIER System achieves an ideal combustion efficiency and power far beyond standard.

About SPI.Systems Corporation Service Professionals, Inc. (SPI), is an engineering company founded in 1992 to provide new systems for support of heavy truck and equipment fleets in reducing their costs of operations and maintenance. That history includes innovations in computerized products and systems of emission control diagnostics and vehicle service on behalf of OEM dealers and independent service organizations.

The company has expanded its focus to include the engineering and production of proven products that enhance engine performance and reduce emissions. The evidence of that commitment is the SPIER SYSTEM™ which applies a new approach to reuse the chemical constituents in diesel exhaust to enhance combustion and reduce the diesel carbon dioxide and nitrogen oxide footprints to a degree never considered possible. To accomplish such an achievement, the company applies a combination of physical and organic chemistries to the thermodynamic principles of engines.

About SPI’s Founder SPI was founded by Jack Schickler, its current President and CEO. Jack is a retired General Motors executive with over 55 years of emission control engineering experience. He has formed several companies that provide performance solutions for both vehicles and equipment. SPI takes what Jack calls a “holistic” approach with his teams. His passion is evident in the creation of the SPIER System™ as a contribution to reducing global warming, which Jack believes can be done with the inventiveness of those who apply their technical knowledge to solving societal problems.
