A battery pack for use in providing starting power for a starter motor of an internal combustion engine and to supply power to one or more auxiliary loads. The battery pack includes an outer housing that encloses a plurality of battery cells. The battery pack further includes a control module. The control module includes a processing circuit configured to control one or more functions associated with the internal combustion engine and an interface circuit configured to interface with the internal combustion engine.

Methods and systems are provided for improving fuel economy by opportunistically lowering engine idle speed below a base idle speed when electrical loads are not present. A hydraulic brake pressure is increased when the idle speed is raised, in anticipation of vehicle propulsion. The brake pressure counteracts any creep torque and unintended vehicle acceleration resulting from the rising engine idle speed.

Cross-port air flow that improves engine fuel economy and reduces pumping losses during part-throttle operation can be implemented in various types of internal combustion engine systems using ports that interconnect the intake ports of different cylinders, thus allowing different cylinders to share combustion air. Cross-port air flow is commenced during part-throttle engine operation to disrupt the primary combustion air flow from each throttle to its associated cylinder, which reduces charge density and engine power. The engine compensates for the reduced power by incrementally opening the throttles, thus increasing the primary combustion air flow, reducing pumping losses and improving fuel economy.

An electronic governor system includes a motor, a transmission coupled to the motor, a throttle plate coupled to the transmission, the throttle plate movable to multiple positions between closed and wide-open, wherein power is supplied to the motor to move the throttle pate to a desired position and wherein power is not supplied to the motor to maintain the throttle plate in the desired position.

An engine control system of a vehicle includes a cylinder control module configured to: determine a target sequence for at least activating and deactivating cylinders of an engine based on a torque request; and activate and deactivate the cylinders of the engine according to the target sequence. A values module is configured to determine, based on the target sequence, a plurality of coefficients and an offset value. An indicated mean effective pressure (IMEP) determination module is configured to determine an IMEP of a first cylinder based on: the plurality of coefficients; the offset value; and a plurality of engine speeds at a predetermined crankshaft positions, respectively.

A method of controlling vehicle inducement in response to an override request includes transmitting, by a controller, an override request to a remote computing device. The override request includes a fault condition resulting in a vehicle inducement that limits a performance parameter of the vehicle to a first value. The method additionally includes receiving, by the controller, instructions from the remote computing device in response to the override request. The instructions include an inducement calibration including a second value of the performance parameter. The method further includes controlling, by the controller, the vehicle inducement to limit the performance parameter of the vehicle to the second value.

A method for controlling a delivery of driving torque of an engine of an agricultural tractor comprising a first step of monitoring a speed of said engine, and when said speed is stable, comprising a second step of maintaining it subsequently stable by compensating a load variation applied to the engine. The invention also concerns a fuel injection system implementing the above method.

A system and method for limiting a speed of a vehicle is disclosed. The vehicle includes an ECU in communication with and configured to control the engine. The ECU has a plurality of pins, a jumper plug connected to the plurality of pins, and a cap selected from a group of caps, each of which is configured to create a different limit circuit when installed on the jumper plug. The ECU is configured to limit the speed of the vehicle to a predetermined speed when the limit circuit is detected by the ECU based on the detected cap. The ECU, jumper plug, and cap are covered by a cover secured to the frame of the vehicle by fasteners that require a tool to remove.

A controller associated with an engine monitoring system may determine a voltage value concerning at least one supercapacitor associated with the engine monitoring system. The controller may selectively cause, based on determining whether the voltage value satisfies a voltage value threshold, the at least one supercapacitor, or a battery associated with the engine monitoring system, to provide electrical power to a sensor system associated with the engine monitoring system. The controller may obtain, from the sensor system, vibration information relating to an engine associated with the engine monitoring system and pressure information relating to a crankcase of the engine. The controller may determine, based on the vibration information and the pressure information, engine speed information related to the engine and may send the engine speed information to a monitoring device.
