Abstract
A four-cycle, fuel lubricated, internal combustion engine system suited for a vehicle includes a fuel tank containing fuel at a remote location from the engine, a first fluid path for transporting fuel to the lubrication system of the engine, and a second fluid path for transporting fuel to said combustion system of the engine. In this way, the engine's fuel serves as the lubricant and the combustive agent. Certain load bearing surfaces of the engine can include a hard material based on borides, carbides and nitrides, a super-hard steel, a self-lubricating material, or a diamond-like coating. The fuel can be one of liquefied petroleum gas, bio-diesel, natural gas, biogas, methanol, Fischer-Tropsch fuel, ethanol, n-pentene, hexane, n-heptane, isooctane, or hydrogen. Also, additives such as molybdenum disulfide, graphite, soybean derived oil, canola oil, polytetrafloeraethylene (PTFE), zinc dialkyldithiophosphate, polyalphaolefin, dibasic organic esters, or mineral oil can be added to the fuel.
