摘要： A method for coolant pump flow rationalization using coolant pump parameters includes calculating a first pump coolant flow based on a coolant input pressure sensor signal and the coolant pump speed. Further, the method includes calculating a second pump coolant flow based on coolant pump current and coolant pump speed when the first pump coolant flow is greater than a predetermined threshold; and comparing the first pump coolant flow with the second pump coolant flow to rationalize the coolant pressure sensor signal.

摘要： A thermal management system includes an electric coolant pump, power source, and controller. The pump is in fluid communication with a heat source and a radiator, and has pump sensors for determining a pump voltage, speed, and current. The battery energizes the sensors. The controller receives the voltage, speed, and current from the sensors, determines a performance of the pump across multiple operating regions, calculates a numeric state of health (SOH) quantifying degradation severity for each of a plurality of pump characteristics across the regions, and executes a control action when the calculated numeric SOH for any region is less than a calibrated SOH threshold. The pump characteristics include pump circuit, leaking/clogging, bearing, and motor statuses. A vehicle includes an engine or other heat source, a radiator; and the thermal management system. The controller may execute a prognostic method for the electric coolant pump in the vehicle.

摘要： An MBT ignition time and a knock ignition time are acquired from an engine rotation speed and engine load, and an ignition time on a delay angle side, out of these ignition times, is set as the most advance angle ignition time. An ignition time on the delay angle side only by the KCS learning value with respect to the most advance angle ignition time is set as a required ignition time, and when an actual ignition time set by a knock control system exceeds a predetermined amount and is positioned on the delay angle side with respect to the required ignition time, it is determined that abnormality occurs in an oil jet. Fail-safe processing to the effect that the opening degrees of a throttle valve are corrected to a closed side is executed in response to the abnormality determination.

摘要： Systems and a method are provided for determining a change in performance of a radiator fan. In one example, a system includes a controller configured to receive a signal output from an accelerometer positioned proximately to and/or operatively coupled with a bearing of a radiator fan, process the signal to determine a peak to peak acceleration value, and indicate a change in performance of the radiator fan when the peak to peak acceleration value is greater than a designated threshold value.

摘要： An engine cooling system is provided with an internal combustion engine defining a head cooling jacket and a block cooling jacket in a split flow configuration. A first thermostat is positioned at an outlet of the block cooling jacket and configured to control coolant flow therethrough. A second thermostat is positioned to receive coolant flow from the first thermostat and the head cooling jacket. The first and second thermostats are in a thermostat assembly within a housing. In response to coolant temperature being below a first threshold, a first and a second thermostat downstream of the engine in a thermostat assembly are closed such that coolant flows through a head jacket and the thermostat assembly to a pump, and such that coolant in the head jacket entrains a trickle flow of coolant from a block jacket through an interbore cooling passage, thereby cooling an interbore region.

摘要： An engine ECU executes a program including a step of calculating intensity values LOG(V) based on signals transmitted from a knock sensor; a step of deciding a maximum value V(MAX) in frequency distribution of intensity values LOG(V) for N cycles (N is a natural number); a step of calculating a knock determination level V(KD) based on the frequency distribution; a step of, when the knock determination level V(KD) is smaller than the maximum value V(MAX), removing V(MAX) from the frequency distribution; and a step of counting the total frequency of removed maximum values V(MAX) as knock occupancy KC. Maximum values V(MAX) are removed until the knock determination level V(KD) and the maximum value V(MAX) coincide, and the knock determination level V(KD) is recalculated.

摘要： The present invention removes voltage that accumulates over a period of time in an automotive engine cooling system. This accumulation of voltage is provided a path to travel inside the engine and cooling system by the cooling liquid used to cool the vehicles engine. This accumulation of voltage looks for a likable metal to bond with and the constant colliding of the voltage trying to bond with the metal creates damage know as electrolytic metal erosion. Overtime this act of nature erodes and weakens metal cooling system components causing them to fail. This process can lead to the vehicle breaking down due to its engine overheating. The electronic voltage remover is designed to remove and dissipate this harmful voltage from the vehicle's engine cooling system.
