Abstract: A method for distinguishing between combustion issues and sensor faults within an engine includes monitoring pressure sensor data from a cylinder within the engine, monitoring engine data describing combustion health from a source other than a pressure sensor, analyzing the pressure sensor data to diagnose an anomalous combustion event, comparing the anomalous combustion event to analysis of the engine data, and indicating a pressure sensor fault warning if the comparison diagnoses a pressure sensor fault.

Abstract: A method for diagnosing combustion within an engine includes monitoring pressure cylinder pressure and generating a measured combustion phasing value for the cylinder at a predetermined metric selected to index the combustion cycle. The measured combustion phasing value is calculated through a Fast Fourier Transform and compared to an expected combustion phasing value.

IPC: F02D41/06
Abstract: A method for controlling operation of an internal combustion engine operating lean of stoichiometry is described. The engine comprises a multi-cylinder direct-injection engine, the engine operative in repetitive cycles each cycle comprising intake, compression, expansion, and exhaust strokes. The method comprises adapting a plurality of fuel injectors to directly inject a first and a second mass of fuel into the cylinders during each cycle. Pressure sensing devices monitor in-cylinder pressure in the cylinders during ongoing operation. The first mass of fuel is injected into one of the cylinders. A cylinder pressure ratio is determined in the cylinder subsequent to injecting the first mass of fuel based upon the monitored pressure. The first mass of fuel injected is adjusted during a subsequent cycle based upon the cylinder pressure ratio.

Abstract: The invention comprises a method to determine a position of a piston in a cylinder of an engine during ongoing operation, comprising adapting pressure sensing devices to monitor in-cylinder pressure, and, operating the engine. In-cylinder pressure is monitored along with a corresponding engine crank position. The engine is operated in a motoring mode and in a cylinder firing mode, and a plurality of instantaneous in- cylinder pressure states are determined during compression and expansion strokes. Pressure ratios are determined based upon the instantaneous in- cylinder pressure states, which are used to determine an engine crank angle and compression ratio error and, adjust the monitored engine crank position based upon the crank angle error and readjust engine operation according to these sensed errors.
