摘要： 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.

摘要： A heated fuel injector system and controller that includes a temperature sensing means to provide closed-loop control of a heating element heating fuel dispensed by a heated fuel injector. Closed-loop control provides more accurate temperature control of the heating element so that fuel heating is provided as quickly as possible while also protecting the fuel from being boiled and protecting the heated fuel injector from being damaged by excessive temperature. By monitoring how the signal from the temperature sensing means varies over time, fault conditions such as a lack of fuel flow, and fuel ethanol percentage may be detected.

摘要： An engine management and fuel delivery system allows an internal combustion engine to operate on liquid fuel such as gasoline, ethanol or a blend thereof, or compressed natural gas (CNG). A first set of fuel injectors is configured to deliver liquid fuel to the cylinders. A second set of fuel injectors is configured to deliver natural gas to the cylinders. An electronic controller is configured to generate fuel injection signals for one of the sets of injectors. An injector selector is configured to direct such fuel injection signals to either the first set of fuel injectors or the second set of fuel injectors based on a fuel type command. The fuel type command is indicative of a desired fuel type selected from either liquid fuel or CNG fuel. The fuel type command is synchronized in accordance with an engine crankshaft position signal in order to coordinate the switchover, for each one of the fuel injection signals, one by one, as each fuel injection event is completed.
