The PSI 8.8-Liter CNG engine will come in naturally aspirated and turbocharged
variants.The naturally aspirated version will be rated at 250 hp and 500
lb-ft of torque and the turbocharged version at 350 hp and 660 lb-ft of
torque. These engine models are specifically matched to the performance
required for Class 4-6 trucks where there are very limited options available
today. PSI is one of the largest industrial and alternative fuel engine
providers in North America with decades of experience in optimizing engines
and has supplied in excess of 2 million cost-effective engines for a variety
of applications including mobility and power generation.

Quantum is designing, developing, and validating an OEM level CNG fuel supply
system to maximize the efficiency and durability of the CNG components. The
system is based on the over 20,000 alternative fuel systems that Quantum has
supplied to a variety of automotive manufacturers, including General Motors
for cars, vans, light-duty and medium-duty trucks over the last two decades.
Quantum intends to supply select components to PSI to support volume
production of the 8.8-Liter engine.

Packaging the new PSI 8.8-Liter natural gas engine with Quantum's
industry-leading Q-Lite™ ultra-lightweight carbon composite natural gas
storage systems will enable the companies to provide complete, pre-qualified
and fully-integrated CNG drive systems to medium-duty truck manufacturers.

"Medium-duty truck manufacturers haven't had an option for CNG engines in the
larger Class 4-6 truck applications," said Gary Winemaster, CEO of Power
Solutions International. "Truck OEMs have asked for an engine with the
performance of our 8.8-Liter CNG engine and we'll be delivering later this

"Quantum is proud to be supporting PSI in the new 8.8-Liter natural gas engine
development," said Brian Olson, President and CEO of Quantum. "We are pleased
to leverage our experience in developing natural gas fuel systems and
performing Tier-1 level system integration, validation and volume production
of systems."
