20090008475 | Heated fuel injector for cold starting of ethanol-fueled engines - A fuel injector for heating fuel to be injected into an internal combustion engine. A cylindrical barrel extends between a solenoid and an injection tip for passage of fuel. The outer surface of the barrel supports a suitable circuit pattern formed of an electrically resistive material for generating heat which is passed through the wall of the barrel to warm the fuel which may be stationary or flowing. The electrically resistive material has a positive thermal coefficient, permitting voltage to be applied continuously across the heater causing a current to flow through the heater, the current being inversely proportional to the temperature of the heater. Thus, the heater is self-regulating, the current automatically increasing under cold conditions and diminishing as the fuel injector warms up after starting of the engine. Desirably, the heater is outside both the engine firing chamber and the flow path of the fuel. | 01-08-2009 |
20090126705 | Heated fuel vaporizer for enhanced cold starting of an internal combustion engine - A heated fuel vaporizer is disposed in an intake component, such as a throttle valve or an intake manifold, of a fuel injected and spark-ignited internal combustion engine. The engine may be fueled by any liquid fuel, such as gasoline, diesel or by fuels much less volatile than gasoline, for example, alcohols such as ethanol, or mixtures of ethanol and gasoline. A configurable heating element is made from a single piece of sheet metal and includes one or two grids each formed by slots and segments. By controlling the geometry of the element, the power and surface area can be configured to any desired value. A single piece heater assembly is designed for installation in an intake component, such as throttle valve or intake manifold, of an internal combustion engine. The heater assembly includes a single-grid or dual-grid heating element that is over-molded with a high melting temperature polymer. | 05-21-2009 |
20090294552 | Heated fuel injector - A heated fuel injector includes a heated body, liquid fuel flowing through a fuel passage within the body, and a member that increases heat transfer from the heated body to the fuel within the fuel passage. The thermal efficiency of the fuel injector is increased separately or in combination by diverting the fuel flow along an inner circumferential contour of the heated body, by limiting the volume of fuel bypassing the heated inner surface of the body, by redirecting heat from the body to unheated portions of the fuel flow field within the fuel passage, and by increasing the available contact surface area for heat transfer. Improved heat transfer from the heated body to the fuel is achieved by integrating features that increase the contact surface area into the inside surface of the body or by positioning an insulating or a thermally conductive spacer within the fuel passage. | 12-03-2009 |
20100018962 | Temperature control device for a fuel heater element - A heater temperature closed-loop control circuit includes a basic Wheatstone bridge circuit with an integral heater element, an amplifier integrated circuit receiving a resultant bridge voltage and controlling an amplifier in correlation with the resistance of the heater element, and a supply voltage provided to the Wheatstone bridge circuit when said transistor is turned on. A thermistor may be integrated into the bridge circuit for compensation of ambient temperatures. While the closed-loop control circuit provides a simple and inexpensive method to provide temperature control and protection to any heater element having a positive temperature coefficient, the control circuit may be especially useful for applications in the automotive industry, for example, to control the temperature of a heated fuel injector or of a heated target that generates vapor from liquid fuel injected upon it. | 01-28-2010 |

20100252653 | HEATED FUEL INJECTOR - A heated fuel injector includes a fuel inlet for receiving fuel, a fuel outlet for dispensing fuel from the heated fuel injector, and a heated body having an inside surface fore fluidly connecting the fuel inlet to the fuel outlet. The heated fuel injector also includes a hollow pintle shaft that is reciprocably movable within the heated body for selectively permitting and preventing the dispensing of fuel from the fuel outlet. A fuel passage is formed between the inside surface and the hollow pintle shaft such that fuel flows through the passage from the fuel inlet to the fuel outlet. The hollow pintle shaft defines a sealed chamber within the hollow pintle shaft which thereby increases the efficiency by which the heated body can heat the fuel flowing through the fuel passage. | 10-07-2010 |

20150218938 | Hard-Mounted EM Telemetry System for MWD Tool in Bottom Hole Assembly - An MWD apparatus has a bottomhole assembly for supporting a tool string and an antenna. The tool string has a sensor and an electromagnetic telemetry device. The tool string affixes in a muleshoe and carrier sub of the assembly using a stinger and fastener. An antenna disposes in an emitter sub of the assembly. The antenna is attached to extend from the tool string so the antenna is in electrical communication with the telemetry device. Finally, the portions of the assembly are connected together, and the antenna is affixed in the uphole portion of the assembly using a conductive landing and one or more fasteners. In this way, the tool string and the antenna are held in tension inside the assembly. The MWD apparatus can be used with an air drilling assembly having an air hammer and a motor coupled downhole of the apparatus. Non-magnetic and regular drill collars can couple uphole of the apparatus, along with a jet sub. | 08-06-2015 |
