Publication number: 20090049897Abstract: An electronic engine controller is configured to execute a process of adapting a base value of the volumetric efficiency of an engine through the addition of a correction value of the volumetric efficiency. The process includes comparing an estimated mass air flow value calculated using a speed-density equation, with an actual mass air flow value measured by a mass air flow (MAF) sensor. A percentage error of the estimated mass air flow value as compared to the actual mass air flow value is calculated. When the percentage error indicates that the air flow is at steady state, then the process updates the VE correction value, by integrating the percentage error. The new correction value, thus computed, is then stored in a cell of an array corresponding to the current engine operating condition. The process is configured to add the correction value to the corresponding base value to produce an updated value of the VE, valid for that operating condition.Type: ApplicationFiled: August 24, 2007Publication date: February 26, 2009Inventors: Peter M.

Publication number: 20090048729Abstract: A method for determining whether a variable valve actuation (VVA) device or subsystem is operating in an improper mode of operation is performed in real-time by an embedded engine or powertrain controller configured to monitor and evaluate an already-available knock sensor output signal. The knock sensor output is captured during a predefined sampling window, defined to include a valve closing event when the VVA device is operating in a proper mode. The captured knock sensor output signal is processed to detect the presence (or absence) of a valve closing event. The absence of a valve closing event when one is expected is indicative of a malfunctioning VVA device.Type: ApplicationFiled: August 16, 2007Publication date: February 19, 2009Inventors: James P. Waters, Jon C. Darrow, Timothy W. Kunz, Peter M. Olin

Patent number: 7254478Abstract: A method of estimating the quantity of secondary reaction airflow supplied to the exhaust manifold of an internal combustion engine by an air injection reaction (AIR) system models airflows in an AIR pump, an AIR valve, and a plenum coupling the pump to the valve. The pump flow is modeled based on the pump speed (or pump motor voltage), the pump inlet air temperature and the pressure ratio across the pump, and the valve flow is modeled based on the pressure ratio across the valve and the valve inlet air temperature. The plenum pressure used in the pump and valve pressure ratios is modeled based on the net plenum airflow and the plenum air temperature. The estimated AIR airflow is useful for managing the air/fuel ratio in the engine exhaust system and enhancing the reliability of AIR diagnostics.Type: GrantFiled: March 31, 2006Date of Patent: August 7, 2007Assignee: Delphi Technologies, Inc.Inventors: Andrew D.

Patent number: 6658364Abstract: An improved method of estimating the gas pressure in the exhaust manifold of an internal combustion engine characterizes the engine exhaust system as a restriction, and estimates the exhaust manifold pressure as the gas pressure upstream of the restriction based on calibrated characteristics of the exhaust system and known characteristics of exhaust gas flow through the exhaust system. The estimation is based on a mathematical model that relates the mass flow of gas through the engine exhaust system to the exhaust manifold pressure (i.e., the upstream pressure), the barometric pressure (i.e., the downstream pressure) and the exhaust manifold gas temperature. An estimate of a pressure ratio across the exhaust system is calibrated based on the model parameters, and the exhaust manifold pressure is determined according to the product of the estimated pressure ratio and the barometric pressure.Type: GrantFiled: December 13, 2001Date of Patent: December 2, 2003Assignee: Delphi Technologies, Inc.Inventor: Peter M.

Patent number: 6481423Abstract: An improved method of dynamically estimating the concentration of recirculated exhaust gases in air/fuel mixture of an internal combustion engine equipped with an exhaust gas recirculation (EGR) system. The EGR concentration at engine intake ports is separately estimated with static and dynamic models, and the EGR concentration for control purposes is determined by adjusting the result of the dynamic model based on a deviation of the dynamic model from the static model. This method provides the total EGR concentration, but can alternatively provide the inert EGR concentration through the inclusion of an exhaust inert ratio model.Type: GrantFiled: December 1, 2000Date of Patent: November 19, 2002Assignee: Delphi Technologies, Inc.Inventors: Martin Muller, Peter M.

Patent number: 6016460Abstract: An improved engine control utilizes a model-based technique to obtain an accurate estimate of barometric pressure with significantly reduced calibration time and effort. A mathematical model of mass air flow through the engine intake system is used to estimate the pressure ratio across the intake system as a function of mass air flow, the effective intake area, and the intake air pressure and temperature. The barometric pressure is then determined from the estimated ratio, and used in the calculation of various gas flows for control purposes. The mass air flow information may be provided by a mass air flow sensor, or alternatively, may be determined based on engine flow rate estimations. Because the estimation is model-based, no special calibration is needed to ensure accuracy at high altitudes.Type: GrantFiled: October 16, 1998Date of Patent: January 18, 2000Assignee: General Motors CorporationInventors: Peter M. Olin, Peter James Maloney
