摘要： A combustion pre-chamber device for a spark ignition internal combustion engine is configured to engage a spark plug and be mounted to a cylinder head in communication with a combustion chamber of a cylinder of the engine. The combustion pre-chamber device includes a number of bores that open at an outer surface thereof that extend into the body and receive a coolant flow to provide cooling for a combustion pre-chamber of the combustion pre-chamber device.

摘要： A method and system of power generating is provided to reduce a startup time of a genset for providing requested power to a utility grid or a load. The genset includes a generator, a turbocharger, and an energy storage. The generator includes an engine. The genset responds to a genset start signal by accelerating an engine speed of the generator to reach a synchronous speed. The engine speed is accelerated more rapidly by activating the energy storage device to supply power to at least one of the generator and the turbocharger. The generator then supplies power to the utility grid or load.

摘要： The present disclosure provides an engine fueling system that includes multiple fueling valves such that the fuel transport delay can be reduced. The fueling system may also include an electrically driven compressor to improve engine properties during engine startup. For example, an engine fueling system comprising: a first compressor; an intake air throttle operably coupled to the first compressor and positioned downstream of the first compressor; a primary fuel path in communication with a fuel supply, wherein a first fuel from the fuel supply is injected into the primary fuel path upstream from the compressor; and a secondary fuel path in communication with the fuel supply, wherein a second fuel from the fuel supply is injected into the secondary fuel path downstream from the compressor.

摘要： A cylinder head [20, 120] mountable onto a cylinder block [16] of an engine [10] is disclosed. The cylinder head [20, 120] includes at least one fastener boss [28, 128] configured for receiving a fastener [24], and the cylinder head [20, 120] is securely fastened onto the cylinder block [16] of the engine [10] by the fastener [24]. A boss cutout [30, 130] is formed on a lower portion of the at least one fastener boss [28, 128] that abuts the cylinder block [16] such that a contact pressure balance of sealing pressures around the cylinder block [16] is evenly distributed.

摘要： Control of an internal combustion engine system in response to a condensation condition associated with a charge air cooler is disclosed. One or more operating parameters of the internal combustion engine are monitored to the control charge air cooler coolant inlet temperature to keep the charge temperature above the estimated dew point to reduce or prevent condensation upstream of the intake manifold.

摘要： A cooling system for a cylinder head of an internal combustion engine includes a cylindrical seat configured to engage an exhaust valve, a first coolant jacket, and a first conduit. The exhaust valve seat defines an annular cooling passage extending along a circumference of the cylindrical seat. A wall of the cylindrical seat defines a first opening into the annular cooling passage and a second opening into the annular cooling passage, where the first opening is positioned diametrically opposite to the second opening. The first coolant jacket is positioned adjacent to a fire-deck of the internal combustion engine. The first conduit fluidly couples the first coolant jacket to the at least one of the first opening and the second opening to the annular cooling passage in the exhaust valve seat.
