Abstract
A motor-vehicle engine system has an internal-combustion four-cycle engine having a fuel-supply manifold, a substantially closed but vented fuel tank holding a supply of gasoline, a fuel pump having an input connected to the tank and an output, and a fuel-feed line connected between the fuel-pump output and the fuel-supply manifold. A controller connected to the engine and to the pump operates the fuel pump at a throughput rate directly related to an engine speed. Insulation at least surrounds and thermally insulates the fuel tank, fuel-feed line, and fuel-supply manifold from their surroundings. A return line connected to the fuel tank is provided with an overpressure valve that is controlled to open briefly only on startup of the engine.
