Reducing turbocharged engine overheating
A method comprising in response to coolant loss in a turbocharged engine, deactivating one or more engine cylinders while limiting engine load of one or more active cylinders based on an engine speed, and a cylinder head temperature.
SYSTEM AND METHOD TO VERIFY INSTALLATION OF ASYMMETRIC PISTON
In one embodiment, a method may include retrieving, via a processor, a fundamental frequency of a cylinder type from a memory communicatively coupled to the processor, receiving, via the processor, a first signal from a first knock sensor disposed on a cylinder. The cylinder is disposed in an engine. The method may also include deriving whether a number of amplitudes of the first signal at the fundamental frequency and one or more harmonic frequencies exceed an undesired installation threshold value, and identifying an asymmetric piston as having an undesired installation if the undesired installation threshold value exceeds the number of amplitudes of the first signal and the one or more harmonic frequencies.
METHOD AND SYSTEM FOR CONTROLLING MOTOR OF FUEL PUMP
A method for controlling a motor of a vehicle fuel pump includes a duty calculation step of calculating, by a motor controller, a duty value of the motor to satisfy a hydraulic pressure of fuel required in accordance with a travel situation of the vehicle, receiving the duty value calculated by the motor controller at the duty calculation step, and determining, by the monitoring unit, whether or not the received duty value is lower than a critical value set in the monitoring unit, and a forced driving step of preventing, by the monitoring unit, a duty value signal from the motor controller from being sent to the motor and directly connecting the motor to a power source, thereby forcibly driving the motor to generate power at a predetermined level when the monitoring unit determines that the duty value calculated by the motor controller is lower than the critical value.
METHOD OF OPERATING A POWER SYSTEM IN A MARINE VESSEL AND A SUPERVISING ARRANGEMENT FOR A POWER SYSTEM IN A MARINE VESSEL
A method of operating a power system in a marine vessel, which power system is operable with at least two operational modes, includes providing a restriction information map by assigning geographical areas with one or more predetermined operational restrictions set for the power system, comparing the location information of the vessel and the restriction information map, and in case the restriction information map includes one or more restrictions assigned to the current location, initiating an intensified supervision operation of the power system, during which data logging operation is initiated and maintained which comprises recording at predetermined interval at least current location information of the vessel, and a specification of used operational mode of the power system at the location and saving the recorded items in a memory media.
Vehicle operations based on biometric fingerprint analysis
Embodiments of the present invention provide a method and system for enacting various driving profiles based on identifying the age and gender of the user. Initially, identifying information is acquired from a user of a vehicle. An identification program determines whether the driver is known, by comparing the identifying information to a set of stored identifying information. If the driver of the vehicle is known, as the identifying information from the user is similar to stored identifying information, then a specific driver profile associated with the specific driver is activated. If the driver is not known, as the identifying information from the user of the vehicle is not similar to the stored identifying information, then the age and gender of the user of the vehicle is determined. Based on the determined age and gender of the driver of the vehicle, various vehicle setting ranges are enacted.
CONTROL APPARATUS AND IGNITION APPARATUS
In a control apparatus, a discharge control unit controls an igniter unit so that a flow of current from a primary coil towards a ground side is blocked, thereby generating a high voltage in a secondary coil, and controls a spark plug so that the spark plug generates electric discharge. An energy input control unit controls an energy input unit so as to input electrical energy to an ignition coil after the start of control of the spark plug by the discharge control unit. A control unit and an abnormality detecting unit detects an abnormality in the igniter unit or the ignition coil based on a first threshold and a first current value that is a value corresponding to a current detected by a current detection circuit at this time, when a first predetermined period elapses after the start of control of the spark plug by the discharge control unit.

APPARATUS FOR CONTROLLING MILD HYBRID VEHICLE AND METHOD OF USING THE MILD HYBRID VEHICLE
An apparatus for controlling a mild hybrid vehicle includes an engine including a plurality of combustion chambers for generating driving torque by burning fuel, at least one intake valve and at least one exhaust valve for opening and closing each of the combustion chambers, an MHSG (mild hybrid starter and generator) for assisting the driving torque of the engine and selectively being operated as a generator, a VVA (variable valve apparatus) including an oil control valve that changes a direction of a path for flowing engine oil in order to adjust opening timing, lift, and duration of the intake valve and the exhaust valve, and a controller operating the MHSG to assist the engine torque when the oil control valve is faulty.
Engine control device and engine device
Provided is an engine control device and an engine device that enable stable self-travelling of the engine in a limp home mode. The engine control device includes a revolution speed detection unit that detects revolution speed of the engine, and an arithmetic unit that calculates an opening of a throttle valve opened by an electronic throttle mechanism, and an injection amount of fuel injected by injectors. In an operation of the engine in the limp home mode, in a case where the revolution speed of the engine detected by the revolution speed detection unit exceeds a predetermined limiting value, the arithmetic unit performs an operation to suppress injection of the fuel to be injected by the injectors.
IGNITION CONTROL AND SYSTEM FOR AN ENGINE OF AN UNMANNED AERIAL VEHICLE (UAV)
The ignition system (10) of an engine (particularly for a UAV) has a primary (10a), and a secondary (10b) ignition system to provide redundancy for get you home capability should the primary ignition system fail. The secondary ignition provides a lower energy or shorter duration spark than the higher energy or longer duration sparking of the primary ignition system, and is retarded relative to primary sparking. Timing of the secondary sparking can be advanced in the event of primary sparking failure. Fuelling strategy can be shifted from a leaner stratified charge to a richer homogenous charge when relying just on the secondary ignition system for ignition. The secondary ignition system can be of a lower spark energy and/or duration than the primary ignition system, avoiding the cost, complexity and weight of replicating the primary ignition system, and to improve packaging within the engine housing, particularly within the limited payload and space limits of a UAV.
