  • Fuel heater for heating liquid fuel under pressure for an internal injection engine
    Patent number: 5690080
    Abstract: A fuel heater for heating liquid fuel under pressure for use in an injector system-injection engine includes a pill 5 made of material with positive temperature coefficient (PTC) with a heatsink member 6, 7 covering both the top and bottom surface of the pill. At least one narrow, preferably spiral-shaped groove 15, 16 extends on either side of the PTC pill, either in the PTC material or in the heatsink material, or in both materials to carry fuel supplied under pressure. The fuel flows into the groove at one side of the pill from a central region of the pill towards the edge of the pill, and then into the groove at the other side of the pill from the edge towards the central region while being heated by the pill. The narrow groove restricts the flow of fuel to keep it under pressure while being heated which then, in turn, provides for the fuel to abruptly convert from a liquid to a gaseous state upon exiting the injector system.
