SYSTEM AND METHODS FOR CBV DIAGNOSTICS

Ford Global Technologies,...

1. A method for diagnosing a continuously variable compressor bypass valve of an engine, comprising:adjusting the continuously variable compressor bypass valve responsive to operating conditions of the engine; and
indicating degradation of the compressor bypass valve coupled in a compressor bypass based on intake aircharge temperature being different then a threshold temperature measured upstream of a compressor inlet, and changing engine operating parameters due to the indication.

SYSTEMS AND METHODS FOR PERFORMING PROGNOSIS OF FUEL DELIVERY

GM Global Technology Oper...

1. An engine comprisinga plurality of combustion cylinders configured to burn a fuel to power the engine;
a plurality of fuel injectors, each arranged to deliver fuel from a fuel tank to one of the plurality of combustion cylinders; and
a controller programmed to
adjust a fuel trim signal gain based on sensing exhaust flow downstream of the combustion cylinders,
monitor a cumulative misfire count for each of the plurality of combustion cylinders, and
issue a prognosis message identifying a state of health of at least one of the plurality of fuel injectors in response to a fuel trim signal gain exceeding an adjustment threshold and a cumulative misfire count greater than a misfire threshold.

METHOD FOR INJECTION VALVES

CONTINENTAL AUTOMOTIVE GM...

1. A method for operating an internal combustion engine with one or more injection valves having nozzle needles activated by a respective piezo actuator, the method comprising:actuating a particular piezo actuator in a pulse-width-modulated manner;
recording the T on and/or T off switching times of the pulse-width-modulated piezo output stage of the particular piezo actuator;
evaluating the recorded switching times to derive a position of the nozzle needle of the injection valve associated with the particular piezo actuator; and
using the derived positions to control actuation of the particular piezo actuator during operation of the internal combustion engine.

NVH MANAGEMENT SYSTEM BASED ON FLOOR VIBRATION FOR VEHICLE AND CONTROL METHOD THEREOF

Hyundai Motor Company, S...

1. A system for managing noise, vibration and harshness (NVH) based on floor vibration for a vehicle, the system comprising:a vibration sensor, which is disposed on a floor of the vehicle and is configured to detect a vibration value thereof;
a control module, which controls an operation of a vibration generating device of the vehicle in response to the vibration value detected by the vibration sensor; and
a display module, which is configured to receive a message and to display information,
wherein when the vibration value detected by the vibration sensor exceeds a predetermined first threshold value, the control module is configured to decrease the vibration by adjusting a driving parameter of the vibration generating device of the vehicle, and
wherein when the vibration value detected by the vibration sensor exceeds a predetermined second threshold value, the control module is configured to generate and output a notice message including information inducing a check of an NVH system and to transmit the notice message to the display module.
