Briggs & Stratton‘s 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.
When converted to propane, the company said 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 three-year limited commercial warranty.
“This is the only engine in this size range that is EPA certified on propane. The engine is also equipped with a catalyst muffler rather than a standard muffler,” said Chris Davison, senior marketing manager of commercial power at Briggs & Stratton. “Using a catalyst muffler and engine tuning, we are able to reduce carbon monoxide emissions by 80 percent to 95 percent and allow the engine to pass engine standards for hydrocarbons and oxides of nitrogen oxide standards. This level of emission reduction would be difficult with a carbureted gasoline engine.”
