Briggs & Stratton Announces Vanguard® 400 Propane Engine Is The First In Its Size Class To Earn EPA Certification

MILWAUKEEOct. 12, 2021 /PRNewswire/ — Briggs & Stratton is pleased to announce the Vanguard® 400 single-cylinder engine, which has been converted to run on propane, has been certified by the Environmental Protection Agency (EPA) as compliant with the Clean Air Act emission standards. This is the first and only engine in its size class with a manufacturer’s warranty, to be converted to propane fuel and receive EPA certification, with California Air Resources Board (CARB) certification on the horizon in 2022.

When converted to propane, a less carbon-dense fuel source, the Vanguard 400 engine with a catalyst muffler provides a significant reduction in carbon emissions. Propane conversion kits allow customers to take advantage of the benefits of propane with their current Vanguard-powered commercial equipment. Available through Propane Power Systems, the kits were developed specifically for Vanguard, and have a 3-year limited commercial warranty*.
