PERC partners with Zenith to develop new high horsepower, cost-saving propane engine

The Propane Education & Research Council partnered with Zenith Power Products to develop a new 11.8-liter engine, designed and optimized for industrial applications including irrigation and power generation. This revolutionary technology earned Zenith an innovation award by the World LPG Association at the 2018 Global Technology Conference.

The spark-ignited industrial engine is the first of a series of high-output stationary engines designed for standby and prime power applications by Zenith, headquartered in Abingdon, Virginia. The heavy-duty engine maintains high thermal efficiencies and low exhaust temperatures, while producing best-in-class low emissions and maintaining the environmental efficiency of all propane-powered engines.

“We were excited to team up with PERC to develop this engine to meet customer demands for a larger engine and help fill a gap in the market,” said Bryan Memmott, president at Zenith Power Products. “Our goal is to give our customers not only initial cost savings and package efficiencies, but also lower operating costs. We’ve completed initial durability testing and are very pleased with the results.”


The engine meets both U.S. Environmental Protection Agency (EPA) stationary and standby emissions standards and is extremely powerful — producing 321 horsepower at 1800 rpm and 937 foot-pounds of torque.

“New propane-powered engines are highly efficient, cost-effective, and easily meet increasing environmental standards,” said Mike Newland, director of agriculture business development at PERC. “As we continue to build our portfolio of propane-powered engines, we work directly with manufacturers to ensure we are creating engines that provide an optimal solution to the challenges of today’s producers. This engine offers reduced operating costs due to lower fuel consumption, higher reliability, and less maintenance, on top of lower engine costs, weight, and emissions.”
