A capless automotive fueling system having a funnel with a port open to receive a fuel filling nozzle. A spring loaded valve is movable between an open position in which the port is open and a closed position in which the fuel valve overlies and sealingly covers the port. A shield is movable between a first position in which the shield overlies and covers the valve, and a second position in which the shield is laterally disposed to one side of the valve to permit insertion of the fuel filling nozzle. A motor is drivingly connected to the shield and, on activation, moves the shield from its first and to its second position. Alternatively, two latches engage the valve to retain the valve in a closed position. Upon insertion of a properly sized fuel nozzle, the nozzle engages the latches and pivots them to an open position.

A process for producing alkyl esters useful in biofuels and lubricants by transesterifying glyceride- or esterifying free fatty acid-containing substances in a single critical phase medium is disclosed. The critical phase medium provides increased reaction rates, decreases the loss of catalyst or catalyst activity and improves the overall yield of desired product. The process involves the steps of dissolving an input glyceride- or free fatty acid-containing substance with an alcohol or water into a critical fluid medium; reacting the glyceride- or free fatty acid-containing substance with the alcohol or water input over either a solid or liquid acidic or basic catalyst and sequentially separating the products from each other and from the critical fluid medium, which critical fluid medium can then be recycled back in the process. The process significantly reduces the cost of producing additives or alternatives to automotive fuels and lubricants utilizing inexpensive glyceride- or free fatty acid-containing substances, such as animal fats, vegetable oils, rendered fats, and restaurant grease.
