Abstract: Methods and systems are provided for a pulley insert. In one example, a pulley insert for a FEAD pulley comprises a first member insertable into a pulley such that the first member is rotatable within the pulley, the first member comprising a cavity for receipt of a second member; and a second member insertable into the cavity of the first member such that, when the first member is inserted into a pulley and the second member is inserted into the cavity of the first member, the second member prevents rotation of the first member relative to the pulley.

Abstract: Methods and systems are providing for improving engine coolant level estimation to reduce engine overheating. The level of fluid in a coolant overflow reservoir is inferred based on the fluid level in a hollow vertical standpipe fluidically coupled to the reservoir at top and bottom locations, while the fluid level in the standpipe is estimated based on echo times of an ultrasonic signal transmitted by a sensor positioned in a recess at the bottom of the vertical standpipe. Engine power is limited differently based on distinct coolant level states determined based on a change in level of coolant in the reservoir over a duration.

Abstract: A line strainer for use in an electric fence system is described. The line strainer includes a unitary body made of electrically non-conductive material, having two opposing arms, a spool mounting element for rotatably mounting an electrically conductive spool having at least one toothed flange between the arms of the body, wherein the spool is configured to have a first line secured to it. The line strainer further includes a line bearing support member about which a second line is to be passed and tensioned. A releasable pawl is attached to the unitary body and configured to engage with the at least one toothed flange to restrict rotation of the spool in one direction when the spool is rotatably mounted to the spool mounting element.

Abstract: The disclosed inventive concept allows an underlying component requiring servicing to be serviced without removing the heat shield entirely. The heat shield has two ends and an intermediate bendable area that allows it to flex, thereby giving the service technician access to the underlying component when only some of the fasteners are removed. The intermediate area of the heat shield is formed from a series of parallel and alternating ridges and grooves. The intermediate area of the heat shield is nominally flat and straight while the bellows are formed in the straight area by a process such as stamping. This combination of a flat and bellow enables the heat shield to be bent out of position and then restored to the original position after service. The heat shield may be entirely formed from a metal or the intermediate bendable area may be composed of a polymerized material such as rubber.

Abstract: Systems and methods for operating a turbocharged engine are described. In one example, a system comprises a cylinder head having a first and second exhaust duct separately coupled to first and second groups of cylinders, each of the first and second exhaust ducts leading to an exhaust driven turbine mounted inside the cylinder head on a bearing, the bearing located within a bearing housing supported by the cylinder head. In this way, exhaust pulses remain separate up to the turbine mounted inside the cylinder head.

Abstract: Methods and systems are provided for reducing turbo lag by directing intake air from an intake manifold to an exhaust manifold. The intake air may be directed via an EGR passage by opening an EGR valve or by may be directed via engine cylinders by increasing positive valve overlap. Amounts of air directed via external EGR and air directed via positive valve overlap are based on engine operating conditions.

Abstract: A fence standard is provided and includes a shaft and a wire support including an open ended loop. The wire support is molded onto the shaft.

Abstract: Methods and systems are provided for expediting light-off of a catalyst during engine cold-start conditions by inhibiting rotation of the turbocharger shaft. In one example, a method may include inhibiting rotation of the turbocharger shaft during engine cold-start conditions until the catalyst is operating at a desired efficiency. The rotation of the shaft may be inhibited via either a passive or an active shaft locking mechanism.

Abstract: Methods and systems are provided for mitigating noise generated by a compressor operating at low flow rates. A swirl device with two concentric flow passages upstream of the compressor directs intake air flow to the compressor through two different flow paths, depending on air flow rates. Angled swirl vanes at an outlet of the swirl device pre-whirl the air flowing to the compressor to reduce noise generation at low air flow rates.
