US Patent:

20130067994, Mar 21, 2013

Filed:

Sep 15, 2011

Appl. No.:

13/233809

Inventors:

Bret Dwayne Worden - Erie PA, US
Milan Karunaratne - Lawrence Park PA, US
Benedict George Lander - Lawrence Park PA, US

International Classification:

G01M 3/26
G01M 15/09

US Classification:

73 405R

Abstract:

Presently disclosed are methods and systems for diagnosing a coolant leak of an engine. A method may include diagnosing a coolant leak of an engine based on identified fill signatures of a measured engine coolant pressure. A vehicle system is also disclosed, including an engine, a coolant system operatively connected to the engine, a coolant pressure sensor configured to measure engine coolant pressure during operation of the engine, and a controller, including instructions configured to create a coolant pressure profile corresponding to a given engine speed, and diagnose a condition of the engine based on the coolant pressure profile.

International Classification:

F16K 37/00

Abstract:

A system and method include measuring input electric current that is input into an electrically controlled valve to change a position of the valve. Output electric current that is output from the valve in response to the input electric current being input into the electrically controlled valve is measured. Position signals are generated using a sensor coupled with the electrically controlled valve that are indicative of the position of the valve. Baseline values associated with the input electric current, the output electric current, and the position signals are calculated. A health state of the valve is determined by comparing the baseline values associated with the input electric current, the output electric current, and the position signals with subsequently measured values associated with the input electric current, the output electric current, and the position signals.

International Classification:

F02M 25/07

Abstract:

Various methods and systems are provided for diagnosing a condition of a component in an exhaust gas recirculation system. In one example, a method includes selectively routing exhaust from a first subset of engine cylinders to an exhaust passage via a first valve and to an intake passage via a second valve and determining a respective condition of each of the first valve and second valve based on a first exhaust pressure of the first subset of engine cylinders and a second exhaust pressure of a second subset of engine cylinders.
