ALTERNATIVE FUEL ENGINES
At JASPER we realize that our products must meet the needs of a diverse audience. We must also meet our nation’s needs to conserve our natural resources and provide for a cleaner environment. Through remanufacturing, we are able to recycle existing drivetrain products and give them new life and usefulness. Our alternative fuel related division and alternative fuel engines take this philosophy one step further as we work to combine power and energy needs with cleaner burning fuels. We truly are a "Green Company".
Clean Air for Tomorrow Through the Technology of Today.
JASPER Alternate Fuels, a division of JASPER Engines & Transmissions, offers complete conversion packages - from alternative fuel engines to all the accessories necessary for the conversion to CNG or propane fuels. Engines are remanufactured and re-engineered to provide excellent performance and reliability when converted to alternative fuel engine applications.
Our alternative fuel engines built to gaseous prepped specifications can run on LP, CNG, methane and even digester gasses.
