摘要： It is widely appreciated that renewable sources of energy are desirable. In particular, in recent years the development of biodiesel has been encouraged in order to find a replacement for fossil fuels in internal combustion engines. Typically, such biodiesel is based on triacylglycerols of vegetable origin. Animal fat, due to its different chemical composition and production process presents additional challenges when attempted to be used as a source of fuel. Most known methods require extensive processing of naturally occurring fats in order for them to be usable in conventional engines. According to the present invention, there is provided a method of oxidizing organic fats within an internal combustion engine to generate power by applying a first electrical charge to an oxidizer (e.g. air) and applying a second electrical charge to the organic fat opposite in polarity to the first electrical charge. In this way, constituents of the organic fat to be oxidized are attracted to the oxidizer, in preference to an interior surface of the combustion chamber. Thus, carbonization of the interior surface of the combustion chamber is reduced, as material contributing to carbonization is retained within exhaust gas.

摘要： A rotary engine includes an insert having a pilot subchamber defined therein and communicating with the internal cavity of the engine. A pilot fuel injector has a tip in communication with the pilot subchamber. An ignition element extends into an element cavity defined through the insert adjacent the pilot subchamber. The element cavity is in communication with the pilot subchamber through a communication opening defined in the insert between the element cavity and the pilot subchamber. The communication opening is smaller than a portion of the ignition element adjacent the communication opening such as to prevent the portion of the ignition element from completely passing through the communication opening upon breaking off of the portion of the ignition element from a remainder of the ignition element. An outer body for a rotary engine and a method of combusting fuel in a rotary engine are also provided.

摘要： A method for controlling electrical power applied to a fuel heater includes applying power to the heater, determining a value for an electrical parameter that varies as a function of the temperature of the heater, and determining a value representative of the time rate of change of the electrical parameter. The method further includes determining the value of the electrical parameter corresponding to a change in the time rate of change of the electrical parameter, wherein the change in the time rate of change of the electrical parameter exceeds a predetermined threshold, and controlling electrical power applied to the heater so as to maintain the temperature of the heater about a target temperature that is a predetermined level below the heater temperature at the time at which said change in the time rate of change of the electrical parameter exceeds the predetermined threshold.

摘要： A fuel supply system for an internal combustion engine includes a heat exchanger that has a heat exchanging wall between a liquefied fuel passage and an engine coolant passage. Heated and vaporized fuel flowing out from the liquefied fuel passage of the heat exchanger is supplied to the internal combustion engine. A flow rate of liquefied fuel supplied to the liquefied fuel passage of the heat exchanger is set. A flow rate of engine coolant supplied to the engine coolant passage of the heat exchanger is determined on the basis of a temperature of the engine coolant supplied to the engine coolant passage of the heat exchanger such that nucleate boiling or transition boiling of the liquefied fuel in the set flow rate occurs near a boundary between nucleate boiling and transition boiling in the liquefied fuel passage.

摘要： A system, heated fuel injector, and controller for closed-loop temperature control of a heated fuel injector having simultaneous two-way data communication over a single-line data connection. The system includes a voltage source to output a heater enable signal and a variable current sink configured to draw a current value indicative of a temperature value related to the heated fuel injector. The heater signal and the current value are simultaneously present on the single-line data connection. The configuration reduces the effect of ground shift on the accuracy of determining a feedback signal from the heated fuel injector. The feedback signal is a temperature value related to the heated fuel injector and is indicated by a current value. Because the feedback signal is a current value, the feedback signal is generally immune from being influenced by ground shift between the controller and the heated fuel injector.

摘要： Fuel temperature management is used to control the penetration distance of liquid-phase fuel into the combustion chamber of direct injection engines. Fuel temperature management enables the alteration of liquid-phase penetration distance to compensate for real-time changes in fuel composition, injector geometry, injection pressure, combustion mode, or combustion chamber thermodynamic conditions during engine operation. Alteration of the liquid-phase penetration distance prevents or reduces undesirable liquid fuel impingement on combustion chamber surfaces.

摘要： An internal combustion engine for motor vehicles, with an intake tube for aspirating combustion air, in which the tube leads to at least one combustion cylinder, and in which tube a throttle valve is disposed. The intake tube effects a mixing of combustion air and fuel vapor downstream of the throttle valve. For the sake of intensive mixing of fuel vapor and combustion air into a largely homogeneous mixture, the fuel vapor generated in a fuel evaporator outside the intake tube is introduced via a delivery device into air turbulence paths that unavoidably develop downstream of the throttle valve in the intake tube as a consequence of the geometry of the intake tube and/or throttle valve.

摘要： A fuel delivery system for an internal combustion engine having an intake air metering device, leading to individual combustion chambers several fuel injection valves, each of which is assigned to one combustion chamber, and a central fuel vaporizer to which fuel can be supplied by a fuel metering device. To reduce pollutant emissions during the warm-up phase of the internal combustion engine after start-up, fuel vapor generated in the fuel vaporizer can be added to the intake air for the combustion chambers downstream from the intake air metering device.
