System, methods, and strategies for regulating charge air temperature in an intake manifold of an internal combustion engine (50) by controlling the flow rate and temperature of liquid engine coolant flowing through a liquid flow path of a charge air cooler (72) that is in heat exchange relationship with charge air entering the intake manifold over a range that provides for the charge air to be selectively heated and cooled by liquid engine coolant. The invention provides flexible control that is useful in controlling exhaust gas temperature for regeneration and/or efficiency restoration of exhaust after-treatment devices (66) as well as improved engine performance.

Methods and systems for aircraft engine trend monitoring include periodically recording the outputs of engine-condition sensors and analyzing the results to examine piston-engine performance trends and predict the need for engine maintenance. Various analyses can be performed, separately or in parallel, including comparing the current parameter values with values recorded for that parameter in previous instances of similar operating conditions; comparing parameter values to predetermined nominal ranges; and detecting parameter values that exhibit trends over time that if followed would result in out-of-bound readings. Sensed parameter values can also be used to detect when recommended engine operating conditions are being exceeded. By using the results of the analyses to inform engine maintenance scheduling and provide alerts to the pilot and maintenance staff regarding recommended engine performance trends and/or operating condition exceedances, the methods and systems contribute to enhancing the level of safety that can be achieved despite significant maintenance-budget reductions.

An equipment transfer device is provided that is transferrable from one support to another support. The transport device is formed as a housing that has two spaced apart, generally parallel recesses, which form docking cups that are open to the bottom. Each docking cup is configured to receive a docking cone that is supported on a structure and is capable of moving in generally a vertical direction into engagement or out of engagement with their respective docking cups. A support post is also supported by the housing and protrudes from the upper end thereof as a base to which an equipment support structure is attached. In this manner the transfer device can be transferred from one docking cone to another with minimal handling and virtually no possibility of dislodgement.

A method, comprising: adjusting an evaporative emissions leak test parameter based on a ratio of cylinder run time of a deactivatable cylinder of an engine, to vehicle run time; and indicating degradation based on the adjusted parameter. The adjusted parameter may thus more accurately reflect the state of a vehicle configured to run with one or more cylinders deactivated. In this way, the evaporative emissions leak test may realize improved robustness and performance metrics, thus reducing warranty costs associated with poor test metrics.

The invention relates to a method and to a device for recognizing a temporary interruption of an electrical supply line between a control device and an adjustment device of an internal combustion engine in a motor vehicle and/or a temporary faulty connection of the supply line to operating voltage or ground. According to the invention, the temporary interruption and/or faulty connection is recorded in an error memory as an interruption, with an identification of the affected supply line. After said recording of the event in the error memory, it is possible at a shop to identify the faulty supply line or the faulty component and to then replace the smallest definable component. According to the prior art, larger assemblies or even non-defective assemblies are sometimes replaced under warranty in order to prevent further visits to the shop. This can be connected with considerable costs, however, such as in the case of electronic control devices.

A real time, average pressure difference method for monitoring doser efficiency is described that determines the difference between the average pressure when the doser is not injecting and the average pressure when the doser is injecting at a predetermined commanded injection rate. The average pressure difference method results in improved doser efficiency monitoring. The method can be implemented in a number of areas. For example, in a diesel truck application, the doser efficiency can be monitored accurately in real time.

Agricultural machines such as sprayers can be improved by providing pressure sensors inside and outside of the operator cab, a cab sensor for sensing an open or closed state of the operator cab, and a controller configured to activate/deactivate an airflow system according to the pressure sensors and the cab sensor. Accordingly, the controller can activate the airflow system to provide a positive pressure differential in the operator cab (higher pressure in the operator cab/lower pressure external to the operator cab), and deactivate the airflow system when the operator cab is in the open state to maximize the life of the system.

A method for forming a component that transmits torque in an automatic transmission includes forming a workpiece with a hub concentric with and extending along an axis and forming the workpiece with a disc that is integral with the hub and extends radially outward from the hub. A hollow perform cylinder is formed integrally with the disc, located at a radial end of the disc distant from the hub, concentric with the axis, and includes an inner surface and an outer surface. A hollow perform cylinder is flow-formed using a flow-forming mandrel located within the cylinder and having an outer surface formed with gear teeth such that the inner surface of the cylinder conforms to at least a portion of the gear teeth on the flow-forming mandrel.

A quantitative metallographic method to measure skin layer thickness in high pressure die cast aluminum components. Because the faster-cooling skin layer region exhibits a higher volume fraction of eutectic phases than that of a slower-cooling inner region, measurements showing such higher eutectic phases can be used to quantify such layer thickness. An image at various thicknesses of a location of interest in a cast component sample is first obtained using an image analyzer, from which eutectic volume fractions within each of the received images may be determined. Comparisons of the determined volume fractions can be made against a known or predicted quantity for a particular alloy composition, and then correlated to the skin layer thickness via differences between the received or measured quantities and those of the known standard.
