A control system for an internal combustion engine structured to operate using at least a first fuel includes at least one sensor configured to sense a condition within at least one cylinder of the internal combustion engine, and a controller operably connected to the at least one sensor. The controller is configured to receive at least one fueling request corresponding to at least the first fuel, send at least one fueling command to at least one injector within the internal combustion engine system corresponding to the at least one fueling request, receive at least one signal from the at least one sensor corresponding to the condition, estimate an actual fueling amount within the internal combustion engine based on the at least one signal, and determine at least one compensation amount corresponding to the at least one injector based on the actual fueling amount.

Control system for internal combustion engine, internal combustion engine system, and method of controlling internal combustion engine

A control system for an internal combustion engine includes at least one sensor configured to measure a combustion signal within at least one cylinder of a plurality of cylinders within the internal combustion engine. The combustion signal corresponds to a first combustion cycle. The control system also includes a controller operably connected to the at least one sensor. The controller is configured to receive the combustion signal from the at least one sensor and determine whether the measured combustion signal satisfies at least one condition associated with the internal combustion engine. The at least one condition corresponds to the at least one of engine misfire or delayed combustion. The controller is further configured to, based on the determination, reduce a fueling amount to the at least one cylinder for a predetermined number of combustion cycles following the first combustion cycle.

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.

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

A combustion pre-chamber assembly includes pre-chamber device body defining an annular plenum that is in fluid communication with the at least one bore that extends through the spark plug shell. The annular plenum is also in communication with at least one purging passage that extends from the annular plenum to an end surface of the pre-chamber device body. Residual exhaust gases in the annular volume of the spark plug are purged by fresh charge flow from the main combustion chamber as the piston approaches top dead center. The fresh charge flow that is provided to the annular plenum through the at least one purging passage and into the annular volume of the spark plug through the at least one bore through the spark plug shell.

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.

Control of a spark ignited internal combustion in response to an exhaust manifold pressure measurement of an engine is disclosed. An engine out NOx amount for at least one cylinder is determined at least in part in response to the exhaust manifold pressure measurement and a brake mean effective pressure of the at least one cylinder. An operating condition of the engine is adjusted in response to the engine out NOx amount.

A compressor bypass reintroduction system includes a compressor intake manifold and a bypass conduit. The compressor intake manifold defines a fluid plenum. The compressor intake manifold is engageable with a compressor. The bypass conduit extends into the fluid plenum and includes an ejector line. The ejector line is configured to be substantially collinear with the compressor and to discharge flow toward the compressor. In some embodiments, an outlet of the ejector is disposed proximate to an outlet of the fluid plenum that discharges flow into the compressor.

A technique for providing electric power to an electric power utility grid includes driving an electric power alternator coupled to the grid with a spark-ignited or direct injection internal combustion engine; detecting a change in electrical loading of the alternator; in response to the change, adjusting parameters of the engine and/or generator to adjust power provided by the engine. In one further forms of this technique, the adjusting of parameters for the engine includes retarding spark timing and/or interrupting the spark ignition; reducing or retarding direct injection timing or fuel amount and/or interrupting the direct injection; and/or the adjusting of parameters for the generator including increasing the field of the alternator or adding an electrical load.

An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, charge motion consistency is improved between engine cylinders and between the left bank and the right bank, thereby improving the consistency of combustion and power output, improving efficiency and reducing emissions (e.g., decreased particulate emissions (also described as smoke), hydrocarbon emissions, and NOx emissions), and further including an improved knock margin, improved fuel economy, wider rich and lean limits, etc.
