Propane fuel system technology for small engines

We Help You!

Our team has been manufacturing propane fuel systems to convert gasoline engines for over ten years. Each EnviroGard Fuel System is carefully calibrated to maximize power and performance while reducing emissions and producing great fuel economy.

We develop and certify propane fuel systems to achieve the highest possible performance while dramatically reducing harmful emissions when compared to conventional gasoline engines. LEHR EnviroGard offers these fuel systems to OEMs in the form of propane engines. In addition, we utilizes a network of trained and certified dealers to perform aftermarket repowers and conversions of gasoline engines to propane.

Propane Engines

Each EnviroGard Fuel System is tested in an independent emissions laboratory and meets the most stringent EPA emissions levels. EnviroGard is proud to offer more certified propane fuel systems than other any manufacturer.

Propane Conversion Kits

EnviroGard Propane Fuel System Conversion Kits allow gasoline engines to operate on propane. EnviroGard does significant dynamometer testing of its conversion kits installed on gasoline engines to ensure peak optimal performance, balancing out horsepower and torque with reduced emissions and increased fuel economy. The result is that converted gasoline engines provide the same performance characteristics as they did prior to conversion.

OEM Solutions

EnviroGard works with both OEMs and trained servicing dealers on the installation of its EnviroGard Fuel Systems. You can be confident that your EnviroGard Fuel System, whether installed at the factory or your local dealer, will perform great each and every time.
