A system for coordinated control of an engine and associated components over various engine-modes of operation. The system may include an engine, one or more components controllable to adjust operation of the diesel engine, and a system controller. The system controller may be connected to the engine and the one or more components. The system controller may include a supervisory controller and one or more component controllers. The supervisory controller may receive system control variable set points and coordinate component control variable set points for the components to achieve the system control variable set points. The component controllers may control operation of the components to achieve the control variable set points for the components by setting manipulated variable set points for the components based on the component control variable set points and a model based non-linear dynamic inversion.

An electronic control unit for a vehicle with a combustion engine and a method of fuel analysis are provided. At least one dynamic torque sensor value from a high pressure pump of the vehicle and at least one additional sensor value including at least one pressure sensor value and/or at least one timing value are used to determine whether a combustible fuel type currently in use is known, unknown, or similar to a known fuel type. In each case, the operation of the combustion engine is optimized using specific parameter configurations for the fuel injectors of the vehicle. The specific parameter configurations are either retrieved from a database, or are generated using artificial intelligence methods.

A system and method for monitoring vehicle performance and updating engine control parameters, which provides a solution to the problem of tuning engine control parameters for a vehicle. The core components of the invention are an engine controller coupled to an interface device which communicates with a remote device. Generally speaking, the components are configured as follows: the engine controller receives signals from various sensors in a vehicle and the engine controller controls the engine based on engine control parameters and the signals from the sensors. The interface device monitors the engine control and sensor signals and transmits information to the remote device. The remote device receives the information and sends back updated engine control parameters. The interface device receives the updated engine control parameters and communicates with the engine controller to update the engine control parameters using the updated engine control parameters.

A monitoring system obtains sensor data associated with operation of an engine, of a machine, that includes a first engine bank with a first set of fuel injectors and a second engine bank with a second set of fuel injectors. The monitoring system determines, based on the sensor data, a first temperature value that is representative of temperature differences between the first engine bank and the second engine bank for a period of time when the engine operated in a particular operation state, and a second temperature value that is representative of temperature differences between the first engine bank and the second engine bank for one or more prior periods of time when the engine operated in the particular operation state. The monitoring system determines, based on the first temperature value and the second temperature value, that a fuel injector malfunction condition occurred during the period of time.

Sub-resolution measurement of fuel in fuel tank. In an embodiment, data, which comprise discrete fuel levels in a fuel tank and fuel injection rates for an internal combustion engine, are received. The fuel injection rates are integrated over a traversed distance to produce a fuel consumption series, and the discrete fuel levels are clustered over the traversed distance to produce a fuel level series. The fuel consumption and fuel level series are synchronized into a model that is used to generate sub-resolution measurements of fuel levels between the discrete fuel levels.
