Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, a method may include supplying air to an exhaust system at a location downstream of an emissions control device via the first exhaust manifold, the air not having participated in combustion in the engine, the first exhaust manifold in fluidic communication with a first exhaust valve of a cylinder and an intake manifold, the cylinder including a second exhaust valve in fluidic communication with the second exhaust manifold. The method may further include adjusting an amount of fuel injected to the engine in response to output of a first oxygen sensor, the first oxygen sensor positioned in the exhaust system upstream of the emissions control device.

Systems and methods for a split exhaust engine system

Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, an air-fuel control method for the engine system may include flowing air from the intake manifold through a plurality of engine cylinders to a junction of the exhaust passage and a bypass passage in response to a condition, the junction positioned along the exhaust passage between first and second emission control devices. The method may further include flowing exhaust gas to the first emission control device while flowing the air to the junction.

Methods and systems are disclosed for operating an engine that includes a knock control system that may determine contributions of individual noise sources to an engine background noise level. The contributions of the individual noise sources may be determined via adjusting timing of a knock window or timing of the individual noise sources.

Method and system for learning contributions of engine knock background noise for a variable displacement engine

Methods and systems are disclosed for operating an engine that includes a knock control system. The methods and system provide for repurposing the engine knock control system to detect and mitigate piston slap. The methods and systems also seek to increase the signal to noise ratio for detecting piston slap.

Method and system for determining piston slap

Various systems and methods are described for controlling an engine in a vehicle, the engine being coupled to a transmission. One example method comprises, under selected braking conditions, shutting-off the engine and spinning-down the engine to rest while the vehicle is traveling, and in response to a foot-off-brake event, restarting the engine by at least partially engaging the transmission and adjusting engine torque control actuators.

Method for controlling an engine during a restart

Methods and systems for operating a torque converter clutch of an automatic transmission are presented. In one non-limiting example, the torque converter clutch is closed to provide a threshold torque capacity during a vehicle launch. If an engine torque request is less than the threshold torque capacity, the torque converter clutch remains closed.

System and method for controlling a torque converter clutch

A system and method for controlling an internal combustion engine include anticipating vehicle launch in response to vehicle position relative to a traffic stream and controlling automatic restart and shut down in response to an anticipated vehicle launch to prevent an automatic engine shut down or to initiate an automatic engine restart. Embodiments include determining vehicle position and traffic position using GPS coordinates. Automatic restart may be initiated in response to movement of a forward vehicle away from the vehicle or in response to a signal from a traffic control device, for example. Automatic shutdown may be inhibited in response to movement of a forward vehicle in cross traffic, in response to a turn indicator being active, or in response to wheel angle, for example.

Assisted direct start engine control for enhanced launch performance

A system for method for emptying a gas storage tank of a vehicle is presented. In one example, engine valve timing is adjusted to facilitate reducing pressure within the gas storage tank. The system and method may extend the use of the gas stored in the gas storage tank.

System and method for emptying a tank

An engine system and method for improving engine starting are disclosed. In one example, engine port throttles are adjusted to improve fuel vaporization of a fuel that includes alcohol. The system and method may improve engine starting and emissions.

Method and system for improving engine starting

A system and method for improving processing of gases contained within the crankcase of an internal combustion engine is presented. The system is especially suited for single boiling point fuels because it allows the storage of such fuels until the fuel can be opportunistically combusted.

System and method for storing crankcase gases to improve engine air-fuel control

Method and systems are provided for controlling a vehicle system including an engine that is selectively deactivated during engine idle-stop conditions. One example method comprises, adjusting a brake torque applied to a deactivated rotating engine after an engine restart request, the brake torque applied to slow the engine to at least a predetermined threshold speed without stopping the engine, and engaging a starter to the still rotating engine to increase the engine speed and restart the engine.
