摘要： A system and method for controlling fuel delivery through a fuel injection system to an internal combustion engine is described. An engine controller calculates a mass of fuel for delivery to one of the cylinders through one of the fuel injectors, based upon the operation of the internal combustion engine. Gas temperature in the intake runner of the cylinder is determined, and a compensation term is selected based upon the calculated mass of fuel and the determined gas temperature in the intake runner of the cylinder. The calculated mass of fuel is adjusted using the compensation term, and the controller controls open time of the fuel injector based upon the adjusted calculated mass of fuel.

摘要： A system for diagnosing a switchable roller finger follower (SRFF) and an oil control valve (OCV) includes a signal monitoring module and a fault detection module. The signal monitoring module receives at least one of an individual cylinder fuel correction (ICFC) signal and an air/fuel ratio imbalance (AFIM) signal when: an engine speed signal is within a predetermined range of speed; an engine load signal is within a predetermined range of load; and a charcoal canister vapor signal is within a predetermined range of flow rate. The fault detection module detects a fault of at least one of a SRFF and an OCV based on an exhaust gas recirculation value and at least one of the ICFC and AFIM signals. The ICFC and AFIM signals are generated based on: an engine position signal; and at least one of an oxygen signal and a wide range air fuel signal.

摘要： A system includes an offset determination module and a correction determination module. The offset determination module determines an offset value based on an average response time of an exhaust gas oxygen (EGO) sensor located upstream of a catalyst in an exhaust system. The offset value relates one of a predetermined number of cylinder imbalance values to a cylinder of an engine. The correction determination module determines a fueling correction for the cylinder based on the offset value and one of the predetermined number of cylinder imbalance values.

摘要： A method of operating an engine includes determining a relative position between a first camshaft and a second camshaft during a startup event of the engine when the first camshaft is at a first home position and the second camshaft is at a second home position. The first home position is a first preset angular position of the first camshaft relative to a crankshaft. The second home position is a second preset angular position of the second camshaft relative to the crankshaft when the engine is in an OFF state. The method includes generating a first estimate of the first home position. The method also includes diagnosing a mis-build of the engine based on the relative position, the first estimate and a second estimate of the second home position.

摘要： A control method for a direct injection gasoline engine operable in stratified or homogenous combustion modes and having a fuel vapor purge system estimates the hydrocarbon concentration of purge vapor during open loop fuel control in the stratified combustion mode, and controls the fuel injection quantity and the combustion mode based on the estimated concentration. The hydrocarbon concentration of the purge vapor is estimated during open-loop fuel control by measuring the air/fuel ratio error during steady state operation with no fuel vapor purging, and using such air/fuel ratio error to normalize the air/fuel error observed during steady state operation with purge control. The fuel injection quantity is compensated for the estimated purge vapor concentration, and engine combustion mode is determined in part based on a comparison of the estimated concentration with a calibrated threshold.
