Abstract: An engine is provided having a fuel supply system which includes apparatus of straightforward construction that is powered solely by a flow of fuel through a delivery line to the engine for increasing the flow of fuel through the delivery line to the engine during start-up of the engine. A small control volume of pressurized fuel is stored during a preceding operational period of the engine for use in augmenting the fuel flow to the engine during a subsequent start-up of the engine. A converter apparatus is also disclosed for converting a portion of the fuel flow from the control volume and/or from a main fuel pump into an increased flow rate or pressure of fuel to the engine during the subsequent start-up. The control volume of fuel is stored in such a manner that volume compensation for changes in ambient temperature is provided, and in such a manner that the fuel line is positively shut off during periods of inoperation such that the fuel cannot leak out or evaporate and thus not be available for rapid start-up of the engine during a subsequent start.
