Ultra-low-emission propane engines from Roush CleanTech can now run on renewable propane, the Michigan-based alternative-fuel technology company revealed in a recent news release.
“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,” the release said.
Earlier in 2018, the California Air Resources Board certified Roush’s 6.8-liter V10 three-valve engine for class 4-7 vehicles as producing ultra-low nitrous oxide emissions, the release said. According to a brochure on Roush’s website, the engine is 75 percent cleaner than the Environmental Protection Agency’s current standard of 0.2 grams per brake horsepower hour.
In using renewable propane, also called biopropane, the engine reduces emission to “n
ear-zero” as defined by the California Air Resources Board, the release said.
It does that “while still being financially viable for fleets,” Rousch president Todd Mouw said in the news release.
Interest in renewable propane is growing because it also reduces greenhouse gas emissions. Since it’s nearly identical chemically to conventional propane, renewable propane can be used as a “drop-in” replacement.
Many companies are developing renewable propane technology, including as a byproduct of renewal diesel, the release said.
“Being relevant as an alternative fuel means constant innovation in technology for the equipment and the fuel,” the release quoted 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.”
