摘要： A fuel vapor generator disposed in the intake manifold of an internal combustion engine. The vapor generator enriches air passing through the manifold to the individual cylinders to enhance engine starting capability, especially at low ambient temperatures. A dedicated fuel injector dispenses atomized fuel onto the surface of an electrically-heated element spaced apart from the nozzle of the fuel injector. The element is positioned within the manifold such that evaporated fuel is immediately swept from the generator by intake air and mixed with air in the manifold. In one aspect of the invention, the location for the heating element is immediately downstream of the manifold air intake throttle valve. The invention is especially useful for spark-ignited engines.

摘要： 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.

摘要： A heat-conducting element having known length D is disposed at a first end in a first region having a first temperature T1 to be inferred. The second end of the element is disposed in a second region having a measureable second temperature T2 different from the first temperature. The element is well-insulated between the first and second regions. Heat flows along the element from the higher temperature region to the lower temperature region, and the temperature of the element at any point along the element is proportional to the temperature difference between the two regions and the distance from either one of the regions. By measuring the second temperature and also a third temperature T3 at a point along the element, and knowing accurately the position Dn of that point with respect to the first and second ends of the element, the first temperature can be inferred by proportionality.

摘要： An assembly having first and second coaxially-related elements oscillatingly-rotatable about a mean angular relationship therebetween. An axial well in one element is threaded and an axial well in the other element is splined. A pin having threads on a first end and splines on the second end is disposed on both the threads and splines of the two elements. A Hall-effect magnetic field strength sensor is disposed coaxially adjacent to the assembly. A permanent magnet mounted on an end of the pin adjacent the Hall-effect sensor creates a magnetic response therein. As the angular relationship between the two elements changes, the pin turns with the splined element, the threads simultaneously displacing the pin and magnet axially of the assembly, thereby changing the intensity of the field experienced by the sensor and the signal output therefrom in proportion to the relative angular position of the two elements. The invention is especially useful for continuous monitoring and control of the advance and retard timing of an engine cam phaser.

摘要： A vane-type cam phaser wherein a realtime method of measuring the axial position of the phaser's locking pin is provided. A magnet is fixed to the nose portion of the locking pin. A Hall-effect sensor is attached to the stator of the phaser in proximity to the magnet. As the locking pin moves through its range of travel, the magnet moves either toward or away from the sensor resulting in a proportional increase or decrease in sensor output voltage. By reading the voltage output, the axial position of the locking pin can be determined.

摘要： A fuel pressure regulator controls the pressure differential across a nozzle which is subject to variations in exhaust gas backpressure having a solenoid actuated valve member which is actuable in response to signals from a controller to establish a predetermined fuel pressure across the nozzle consistent with a control strategy. A pressure dependent valve actuator is operable on the valve member, independently of the solenoid, to adjust the valve opening and, as such, the fuel pressure at the nozzle to adjust the fuel pressure in response to exhaust gas.

摘要： A gaseous fuel injector is provided with a fuel inlet, a fuel outlet, and a conduit for communicating fuel from the inlet to the outlet. A valve and valve seat is provided for selectively preventing and permitting fuel to pass from the fuel inlet to the fuel outlet. The valve seat has a plurality of apertures for providing fluid communication therethrough. The valve has a sealing face for selectively engaging and disengaging the valve seat to selectively prevent and permit fuel from passing therethrough. The valve seat includes a raised seating surface for sealing against the sealing face when the valve is engaged with the valve seat. The raised seating surface is defined by at least one wall that continuously surrounds each aperture. Each wall is in continuous fluid communication with the entirety of each wall downstream of the sealing face when the valve is engaged with the valve seat.
