Publication number: 20130152907Abstract: Electronic induction system tuning featuring electronic pressure charging for an intake tract of an internal combustion engine is disclosed herein. The electronic pressure charging system includes a pressure sensor, a signal generator, and a wave generator. The signal generator causes the wave generator to create a pressure wave in response to monitored parameters and a pressure wave detected by the pressure sensor. The generated pressure wave may be added to, cancel, or otherwise modify the detected pressure wave to increase, decrease, or otherwise manipulate the pressure within a combustion chamber of the engine.Type: ApplicationFiled: December 15, 2011Publication date: June 20, 2013Applicant: CHRYSLER GROUP LLCInventor: Victoriano Ruiz

Patent number: 7996146Abstract: A method of operating a fuel injected multi-cylinder internal combustion engine includes electronically storing a first value or reference value indicative of an engine speed response to a commanded fueling duration change during fueling the engine with a first fuel or reference fuel, such as a known type of diesel fuel. The method further includes operating the internal combustion engine in a fuel testing mode during fueling with a second fuel or test fuel, such as an unknown type of diesel fuel. The fuel testing mode includes determining a second value or test value indicative of an engine speed response to a commanded fueling duration change, comparing the test value with the reference value and outputting a fuel attribute signal which is based at least in part on comparing the reference value and the test value.Type: GrantFiled: December 29, 2008Date of Patent: August 9, 2011Assignee: Caterpillar Inc.Inventor: Victoriano Ruiz

Patent number: 7810460Abstract: A control system for an engine having a camshaft that is associated with an intake valve and a cam phaser that interfaces with the camshaft includes an air flow sensor that outputs first and second air flow signals based on mass air flow (MAF) delivered to the engine. An engine control module communicates with the air flow sensor and the cam phaser. The cam phaser adjusts an actuation time when the camshaft opens the intake valve during rotation of the camshaft. The control module further receives a rotational position signal based on the rotational position of the cam phaser and determines a rotational position of the cam phaser that delivers maximum air to the engine based on a first air flow signal measured prior to adjusting the cam phaser and a second air flow signal measured subsequent to adjusting the cam phaser.Type: GrantFiled: February 15, 2008Date of Patent: October 12, 2010Inventor: Victoriano Ruiz

Patent number: 7761222Abstract: A method of operating a fuel injected multi-cylinder internal combustion engine includes establishing a flow shift compensation term by comparing a pre-flow shift value with a post-flow shift value. The pre-flow shift value is indicative of a pre-flow shift fueling signal duration linked with an engine test speed, and the post-flow shift value is indicative of a post-flow shift fueling signal duration linked with the engine test speed. The method further includes controlling an engine speed via outputting fueling signals from a digital engine speed governor to a plurality of fuel injectors of the internal combustion engine.Type: GrantFiled: December 29, 2008Date of Patent: July 20, 2010Assignee: Caterpillar IncInventor: Victoriano Ruiz

Publication number: 20090108095Abstract: A fuel injection system is disclosed. The fuel injection system has a nozzle member configured to receive fuel and having at least one injection orifice and a valve disposed with the nozzle member and movable between an open position at which fuel flows through the at least one orifice and a closed position at which fuel flow through the at least one orifice is blocked. The fuel injection system also has an actuator coupled to the valve and configured to move the valve between the open position and the closed position in response to a signal applied thereto and a controller in communication with the actuator, the controller being configured to apply to the actuator an ultrasonic frequency signal such that the valve remains at or between the open position or the closed position and vibrates at the ultrasonic frequency.Type: ApplicationFiled: October 30, 2007Publication date: April 30, 2009Inventor: Victoriano Ruiz

Patent number: 7469678Abstract: An engine control system to adaptively adjust the spark timing values in spark timing tables to achieve a mean best torque. The engine control system utilizes a spark timing module that contains spark timing values as a function of one or more operating conditions of an engine. An ignition module can command spark timing based on the timing values in the spark timing module. The ignition module can adjust the spark timing during engine operation within a predetermined operating window. The spark timing values in the spark timing module can be changed based on changes in engine operation as a result of the adjustment to the spark timing. The adjusting of the spark timing and the replacing of the spark timing values in the spark timing module can allow the spark timing in the spark timing module to be optimized.Type: GrantFiled: June 6, 2007Date of Patent: December 30, 2008Assignee: GM Global Technology Operations, Inc.Inventor: Victoriano Ruiz

Patent number: 7380547Abstract: A control system for adjusting levels of emissions exiting an engine includes a NOx sensor that generates a NOx signal in response to oxides of nitrogen (NOx) in an exhaust gas and a control module that communicates with the cam phaser. The rotational position of the cam phaser controls an actuation time when the camshaft opens the exhaust valve during rotation of the camshaft. The control module further receives the NOx signal, and calculates a NOx level of the exhaust gas based on the NOx signal. The control module compares the NOx level to a predetermined threshold range and adjusts the cam phaser to achieve a rotational position that releases a desired level of NOx from the engine when the NOx level exceeds the predetermined threshold range. The control module further stores the rotational position in a storage device when the NOx level is within the predetermined threshold range.Type: GrantFiled: November 17, 2006Date of Patent: June 3, 2008Assignee: GM Global Technology Operations, Inc.Inventor: Victoriano Ruiz
