EnviroGard Propane Fuel System
How It Works:
1. Application Specific Brackets
EnviroGard application specific brackets are designed to maintain the correct weight and balance of the equipment being converted as well as provide for easy installation.
2. Vapor Propane Cylinder
Specifically designed for engine applications, these DOT approved propane cylinders feature numerous safety features. Cylinder mounting brackets make mounting cylinders easy.
3. High Pressure Fuel Hose
4. Safety Fuel Lock-Off
EnviroGard’s Safety Fuel Lock-Off is a safety device designed to shut off the fuel flow from the propane cylinder to the regulator in the event of engine failure or loss in oil pressure.
5. EnviroGard Regulator and Mounting Bracket
EnviroGard regulators are designed to provide the optimal amount of fuel to the EnviroGard carburetor. Mounting brackets are specifically designed for each engine and make ensure the regulator is securely mounted in the correct position.
6. Low Pressure Fuel Line
7. EnviroGard Carburetor
EnviroGard carburetors are calibrated to provide a stoichiometric air/fuel ratio which results in optimal power, performance, and fuel economy while producing ultra-low emissions.
8. EPA Certified Engine
EnviroGard only offers propane conversions that when installed maintain the EPA engine certification and engine warranty.
Lower Fuel Costs & Simplifies Refueling
Propane, on average, is 30% less expensive than gasoline. Propane is domestically produced and historically there has been a surplus of supply resulting in the low prices. The United States has an abundant supply of Propane and Natural Gas, therefore prices of Propane should continue to be much lower than gasoline for the foreseeable future. Propane marketers make refueling easy, offering tank exchange programs or bulk filling cylinder at the operator’s location.
Propane is an extremely clean burning fuel that utilizes a closed fuel system. As a result, engine components run cleaner and require less maintenance. Propane also contains no ethanol which eliminates gummed up carburetor components.
The United States is a net exporter of propane. Most propane is made in Texas as part of the oil and natural gas refining process. Propane is a designated Clean Fuel by the Environmental Protection Agency and its use qualifies for state and federal rebates. Propane is also the most widely available alternative fuel.
Reduced Harmful Emissions
Propane contains only 3 carbon molecules vs. gasoline which contains 8 carbon molecules. As a result, propane produces very low carbon emissions. LEHR propane engines typically reduce carbon emissions 65-70%.
State and Federal Grants
The Propane Education & Research Council as well as other federal and state agencies offer incentives to convert engines to operate on propane.
Mow on Ozone Action Days
Many states and municipalities have enacted Ozone Action Days where use of smog forming gasoline lawn mowers are prohibited. Mowers that operate on propane are exempt from Ozone action days.
THE LEHR PROPANE PROCESS
What is Propane?
Originating mainly from natural gas production, propane is a nontoxic, nonpoisonous gas that does not contaminate soil or water. Propane is the cleaner, cheaper greener alternative fuel. Propane can be up to five times more efficient than traditional fuels, resulting in less fuel being used
Propane is an approved alternative fuel listed in both the clean air act of 1990 and the National Energy Policy Act of 1992
Propane exhaust creates 60 percent to 70 percent less smog producing hydrocarbons than gasoline, according to studies by the Southwest Research Institute.
Propane engines are up to 50 times cleaner than gasoline engines.
Propane cuts emissions of toxins and carcinogens like benzene and toluene by up to 96%, compared to gasoline, according to studies by the Southwest Research Institute.
Propane does not contain Class I or II ozone-depleting chemicals (40 CFR Part 82).
Propane is not listed as a marine pollutant by DOT (49CFR Part 171).
Propane has built-in safety properties.
