ROUSH CleanTech Launches Near-Zero Emissions Engines

ROUSH CleanTech, an alternative-fuel technology company, revealed that its 0.02 grams per brake horsepower-hour engine can operate on renewable propane. It’s the first available engine for renewable propane that brings emission levels to near-zero, as defined by California Air Resources Board, according to ROUSH CleanTech.

“When commercial vehicles are equipped with our ultra-low NOx engines and fueled by renewable propane, they achieve near-zero emissions while still being financially viable for fleets,” said Todd Mouw, president of ROUSH CleanTech. “These clean-operating, medium-duty trucks, vans and buses enable fleets to take a giant leap toward meeting their state’s clean air standards, especially in California.”

Renewable propane is a non-fossil fuel that is produced from 100-percent renewable raw materials, such as waste, residue and sustainably produced vegetable oils. There is growing interest in renewable propane-also known as biopropane-due to its near-zero emission levels, reduced greenhouse gases and ability to help meet growing demand for cleaner products. It can be used as a drop-in replacement fuel because it’s chemically nearly identical to conventional propane, according to Roush CleanTech.

Many companies in the U.S. and around the globe are developing renewable propane technology, with some production in commercial volume as a byproduct of renewable diesel plants.

“Being relevant as an alternative fuel means constant innovation in technology for the equipment and the fuel,” said Tucker Perkins, president and CEO of the Propane Education & Research Council. “Renewable propane is just one example of that innovation, along with increasing engine efficiency and modern dispensers with near-zero emissions.”

“Because of their clean-burning properties, propane-fueled vehicles should be very competitive when it comes to seeking funding,” Mouw said. “In California alone, there are several grants, rebates and incentives to help cover the costs of adopting emissions-reducing transportation technology.”

Earlier this year, ROUSH CleanTech received California Air Resources Board certification for its ultra-low NOx 6.8L V-10 3V propane engines for Class 4-7 vehicles. When fueled by traditional propane autogas, the engine is 90-percent cleaner than national emissions standards.
