After two years of development,
Power Solutions International introduced an 8. 8 L engine that can run on
propane, compressed natural gas or gasoline.
THE GROUND UP
Power Solutions International develops own 8. 8 L spark-ignited engine
capable of operating on gasoline, CNG or propane
BY JACK BURKE
For years, Power Solutions International (PSI) has sup- plied spark-ignited alternative fuel engines to the construction,
industrial and agricultural markets.
Its product line encompasses 15
engine displacements ranging from
0.97 to 22 L, many of which are
based on General Motors (GM) automotive engines.
But when in early 2010 GM decided
to end production of its 8. 1 L engine,
PSI faced a decision. The 8. 1 L was
one of its most popular engine mod-
els, one that fit an important niche
for PSI that the company didn’t want
to lose. Yet without a base engine to
work with, its options were limited.
