摘要： A self-contained, stand-alone power generator system comprising: an electric motor for applying torque to a shaft of a rotating mass, wherein the electric motor is powered by a dedicated power source; a battery for supplying additional power to the electric motor upon start up; at least one of a torque converter and a starter motor, for overcoming resting inertia of the rotating mass; a generator head coupled to the rotating mass, wherein the power generator is constructed such that when the generator head reaches operational speed, the generator head provides the additional power to the electric motor and recharges the battery.

摘要： An intake variable valve timing mechanism (VVT) that collectively changes an intake valve close timing as a close timing of a plurality of intake valves and a control device that controls an engine including a plurality of injectors and the intake VVT are provided. When a specified engine stop condition is satisfied, a fuel cut is performed to stop a fuel supply into a plurality of cylinders by the injector. After the fuel cut, the intake VVT is controlled such that a retarded amount of the intake valve close timing immediately before a stop of a stop-time compression stroke cylinder as a cylinder stopped in a compression stroke from intake bottom dead center is larger than a retarded amount of the intake valve close timing immediately before a stop of a stop-time expansion stroke cylinder as a cylinder stopped in an expansion stroke from the intake bottom dead center.

摘要： A decompression shaft (56) of a decompression device (50) includes an engagement pin (53) that is guided by a guide groove (51a) formed in a decompression weight (51), a decompression cam (54) that is provided on one cam surface of an intake valve cam (25c) and an exhaust valve cam (25b) so as to advance and retreat, and a connection portion (55) that connects the engagement pin (53) and the decompression cam (54). The decompression weight (51) is formed with a rotation restricting groove (51e) that restricts rotation of the decompression shaft (56) when a force acts in a direction in which the decompression cam (54) moves on the decompression shaft (56) from an advanced position to a retracted position when an engine (E) is stopped and that is continuous with the guide groove (51a).

摘要： A silicate mixture and a combustion accelerator increase combustion efficiency in a combustion engine. The silicate mixture is formed by mixing a first component including one or two or more materials selected from silicon compounds including silicon, glass, and quartz, and a second component including one or two or more materials selected from materials formed by sintering a silicate mineral at a temperature of 1300° C. or higher and 2000° C. or lower and ores emitting a terahertz wave.

摘要： One embodiment includes an engine block heating system. The engine block heating system includes a battery bank. The battery bank is configured to supply at least 2.25 KWatt-hours of energy before needing to be recharged. The battery bank is configured to be mounted in a vehicle comprising an engine block heater. The system further includes interface configured to connect to electrical connections of the engine block heater. The interface comprises an inverter is configured to supply at least 1500 Watts of power to the engine block heater. The engine block heating system is configured to selectively supply power from the battery bank to the engine block heater. The system further includes control circuitry coupled to the interface. The control circuitry stores a user-defined schedule to selectively control when the interface electrically connects the battery bank to the engine block heater.

摘要： Systems and methods for operating an internal combustion engine are described. In one example, an engine's position is adjusted during engine stopping so that the engine may be less likely to stop at a crankshaft angle where rotating a fuel pump may increase engine cranking torque due to work performed by the fuel pump.

摘要： Various embodiments include a method for starting an internal combustion engine comprising: in a first phase after a starting process, setting a throttle valve to a value near to zero so the pressure in the intake tract is lowered below the ambient pressure and injecting a fuel into the intake tract above a rich combustion limit at which the fuel/air mixture would still just be combustible; in a second phase, reducing the fuel mass as a function of the pressure; in a third phase shorter than the second phase, further reducing the fuel mass and increasing the opening of the throttle valve to increase the pressure in the intake tract; and in a fourth phase, increasing the fuel mass as a function of rising pressure in the intake tract.

摘要： A method for starting an engine is disclosed. The method may adjust exhaust valve opening timing of one or more cylinders during a first cycle of an engine since a most recent engine stop to reduce engine cranking work. The method may adjust exhaust valve timing if the engine is directly started or started via an electric machine.

摘要： A control device for an internal combustion engine is configured to: execute a first decompression operating processing such that a decompression operating state is selected in a first engine speed region that passes in the course of engine stop; execute a decompression stop processing such that a switching from the decompression operating state to a decompression stop state is performed in the course of the engine stop after passage of the first engine speed region; when a temperature correlation value is greater than or equal to a threshold value upon an engine start-up request, execute a second decompression operating processing such that the decompression operating state is selected in a second engine speed region that passes in the course of engine start-up before the start of fuel injection. When the temperature correlation value is smaller than the threshold value, the second decompression operating processing is not executed.

摘要： Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, an amount of opening overlap between a plurality of intake valves and a first set of exhaust valves coupled to the first exhaust manifold may be adjusted responsive to a transition from an estimated combustion air-fuel content to a leaner air-fuel content of the blowthrough air on a cylinder to cylinder basis. As one example, the transition may be determined from an output of an oxygen sensor positioned within the first exhaust manifold or an exhaust runner of each of the first set of exhaust valves.
