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, the engine system may be installed in a hybrid vehicle, and, in response to a request to restart the engine while the vehicle is being propelled via motor torque only, the engine may be rotated unfueled via the motor torque at less than cranking speed while at least partially opening a valve disposed in a passage coupled between the first exhaust manifold and the intake passage. In another example, in response to the request to restart the engine, all exhaust valves of a second set of exhaust valves coupled to the second exhaust manifold may be deactivated.

Systems and methods for a split exhaust engine system

Systems and methods for improving combustion in a highly exhaust gas diluted engine are disclosed. The methods and systems may be provided in an engine that is supplied two different types of fuel.

Systems and methods for improving operation of a highly dilute engine

Methods and systems are provided for sterilization. In one example, a device may include a body with a flexible tether and a receiving aperture having a central axis, the body forming an internal cavity, the cavity housing at least one circular battery with a central axis perpendicular to the central axis of the aperture; and a UV source positioned at an end of the receiving aperture. Various other additional features and alternative configurations are included.

Sterilizing device and method

Methods and systems are provided for controlling and coordinating control of a post-catalyst exhaust throttle and an EGR valve to expedite catalyst heating. By closing both valves during an engine cold start, an elevated exhaust backpressure and increased heat rejection at an EGR cooler can be synergistically used to warm each of an engine and an exhaust catalyst. The valves may also be controlled to vary an amount of exhaust flowing through an exhaust venturi so as to meet engine vacuum needs while providing a desired amount of engine EGR.

Method and system for vacuum control

Various systems and methods for an engine system which includes a throttle turbine generator having a turbine which drives an auxiliary generator and disposed in a throttle bypass are described. In some examples, a throttle bypass valve is controlled to adjust airflow through the throttle bypass responsive to airflow to cylinders of the engine. In other examples, an operating parameter such as throttle position is controlled based on transient operating conditions of the engine. In still other examples, charging of a battery is coordinated between the auxiliary generator and a primary generator.

Methods and systems for controlling airflow through a throttle turbine generator

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.

Methods and systems for assisted direct start control

Methods and systems for a throttle turbine generator

Systems and methods are provided for monitoring reverse flow of fuel vapors and/or air through a vehicle fuel vapor recovery system, the fuel vapor recovery system coupled to an engine intake of a boosted internal combustion engine. One example method comprises, intermittently adjusting a restriction in the fuel vapor recovery system during boosted conditions, and indicating degradation based on one or more of a change in a pressure value, or based on a change in flow in the fuel vapor recovery system.

Fuel vapor purging diagnostics

Methods and systems are provided for controlling a vehicle system including an engine that is selectively deactivated during engine idle-stop conditions and selectively reactivated during engine restart conditions. One example method comprises, during an engine restart from an idle stop, performing a first combustion event in a cylinder with a piston at an engine crankshaft position that is after a crankshaft position at which said cylinder's exhaust valve opens, and before a crankshaft position at which the cylinder's intake valve closes, during a cycle of said cylinder. In this way, inaccuracies in cylinder aircharge estimation may be reduced, thereby also reducing air-fuel ratio errors and improving the quality and repeatability of engine restarts.

Methods and systems for engine starting

A method is provided for controlling an engine via an outlet control device of an intake manifold, such as via variable valve lift operation. The engine may further include an inlet control device, such as an electronic throttle, as well as coordination between the inlet and outlet control devices for controlling airflow in the engine.

Vehicle control system

Methods and systems for diagnosing a multiple cylinder engine are provided herein. An exemplary method of diagnosing an internal combustion engine system having a multi-cylinder internal combustion engine is described. In one example, cylinder air-fuel imbalance is determined from the squared value of a difference of two values.

Diagnosis for multiple cylinder engine

A method is provided for controlling an engine having two cylinders, one of which having an adjustable valve. The method comprising performing a combustion in two cylinders having pistons, the combustions for said cylinders occurring during a common stroke of the pistons; increasing a number of strokes in a cycle of one of the two cylinders; and returning operation of the one of the two cylinders to four strokes, so that combustion of the one of the two cylinders occurs sequentially from the other of the two cylinders.
