摘要： A system and method for engine control and diagnostics are described. The engine system may include an engine having a catalyst in the exhaust system, the exhaust system further having an exhaust gas oxygen sensor upstream of the catalyst and downstream of the catalyst. In one example, the method may include during a first operating mode in which catalyst diagnostics are not carried out, adjusting air-fuel ratio based on both the upstream and downstream exhaust gas oxygen sensors, where air-fuel ratio adjustment responsiveness to the downstream sensor is reduced as the catalyst performance degrades; and during a second operating mode that includes catalyst diagnostics, adjusting air-fuel ratio based on at least the downstream exhaust gas oxygen sensor, where said air-fuel ratio adjustment responsiveness to the downstream sensor is temporarily increased from said reduction generated during the first operating mode.

摘要： A method for operating a direct injection spark ignition engine in stratified mode and dual mode is presented. The method includes determining a fuel fraction in a fuel vapor canister; determining whether the fuel vapor canister should be purged; performing purge flow from the fuel vapor canister to a cylinder of the engine; and supplying purge flow and injected fuel to a cylinder of the engine during an intake stroke and supplying injected flow during a compression stroke so that the engine operates in the combined homogeneous and stratified charge mode. The method also includes controlling the purge flow and the injected fuel supplied to balance an amount of fuel supplied during the intake stroke and the compression stroke. The step of controlling calculates the amount of fuel to be injected and includes adjusting the amount of fuel supplied based on an amount of purge supplied to the cylinder.

摘要： A fuel vapor purging method controls fuel vapor purging during stratified operation. Several factors influence vapor purge control, including fuel vapor concentration in the cylinder and temperature of the emission control device. The fuel vapor passes through the cylinder unburned by maintaining the concentration within allowable limits. The unburned fuel vapor reacts exothermically in the emission control device thereby generating heat. To guarantee that the fuel vapor reacts in the first emission control device, the fuel vapor purge is restricted to a certain temperature range. To guarantee that the fuel vapor does not burn in the cylinder, the concentration is kept to a restricted value.

摘要： An air/ratio control system and method for an internal combustion engine coupled to a fuel vapor recovery system simultaneously maps a difference between a desired air/fuel ratio and a measured air/fuel ratio to fueling errors and a purge vapor flow. This system and method maximizes the ability to purge the vapor recovery system while maintaining the ability to diagnose fuel errors.

摘要： Methods and systems are provided for monitoring a fuel vapor recovery system including a fuel tank isolation valve coupled between a fuel tank and a canister. During selected conditions, the valve is modulated and pressure pulsations in the fuel vapor recovery system are monitored. Valve degradation is identified based on correlations between the valve modulation and the resultant pressure pulsations.

摘要： Methods and systems are provided for adjusting cylinder valve timings to enable a group of cylinders to operate and combust while another group of cylinders on a second are selectively deactivated. Valve timing may be adjusted to allow flow of air through the inactive cylinders to be reduced, lowering catalyst regeneration requirements upon reactivation. The valve timing may alternatively be adjusted to enable exhaust gas to be recirculated to the active cylinders via the inactive cylinders, providing cooled EGR benefits.
