PSI’s 40L engine recently received EPA certification.

PSI’s new 40-liter stationary spark-ignited engine was recently certified by the U.S. Environmental Protection Agency. The certification, received October 3, covers both stationary and mobile, non-road emission regulations for constant speed operation on both commercial pipeline-quality natural gas (CNG/LNG) and propane (LPG).

The 40-liter engine has a range of 600 kWe to 800 kWe and is now ready for production. The engine is part of PSI’s expanded natural gas product line, which ranges from 2.4-liters to 65-liters of displacement and 25 kWe to 1.2 MW.

Like all of PSI’s power generation products, the 40-liter engine is fitted with the company’s advanced fuel and emission control systems, which are designed to provide application-specific performance.

“The addition of the 40-liter engine provides PSI and its customers exciting new opportunities in the oil and gas and healthcare markets, to name a few,” said Mike Biltimier, vice president of PSI’s Energy Division. “The PSI rich-burn fuel system utilized across our engine platform enables our customers to meet the stringent regulatory requirements as needed in the non-attainment zones while also achieving demand response and performance that meets NFPA 110 and other requirements.”

The 40-liter engine is largely designed for energy market applications including power generation, oil and gas exploration and other industrial sectors.
