摘要： Systems and methods are provided for in-situ determination of engine oil viscosity to allow for selection of an engine map by an engine control module (ECM) to match the detected viscosity. The new engine map selected based on the viscosity can correspond to an engine map based on an engine oil with a different HTHS viscosity than the prior engine map. Instead of requiring a reprogramming of an ECM when the engine oil is changed, an ECM can have access to a plurality of engine maps corresponding to different engine oils at a given HTHS viscosity and/or at different HTHS viscosities. The ability of an ECM to select an engine map corresponding to a different HTHS viscosity based on in-situ viscosity detection can allow the oil in an engine to be changed without requiring access to the ECM for reprogramming.

摘要： Systems and methods are provided for enabling communication, without breaching the engine firewall, between a datalogger located on one side of the firewall and one or more sensor devices that are located on the opposite side of the firewall. The systems and methods described herein can allow a transmitting node (i.e., a transmitting datalogger) to transmit collected data (from an auxiliary sensor) to a receiving node (i.e., a receiving datalogger) while reducing or minimizing various difficulties associated with addition of an auxiliary sensor in the engine environment. The transmission of data from the transmitting node to the receiving node can correspond to wired data communication or wireless data communication.

摘要： A method for improving fuel efficiency testing precision in on-road vehicles. The method comprises: installing one or more dataloggers in one or more vehicles, each datalogger configured to receive fuel consumption data broadcast by an on-road vehicle's engine control unit (ECU); transmitting the fuel consumption data from the one or more dataloggers in the one or more on-road vehicles to a processor; and analyzing, using the processor, the fuel consumption data from the one or more dataloggers in the one or more on-road vehicles to determine fuel efficiency of the one or more on-road vehicles. The fuel consumption data comprises fuel rate data from the ECU which is transmitted through the one or more dataloggers, engine speed and other operating parameters from the ECU that are transmitted through the one or more dataloggers, torque sensor data which is transmitted through the one or more dataloggers, and traditional fuel log data.

摘要： Disclosed are lubricating compositions comprised of a mineral oil base stock including one or more components selected from the group consisting a Group I base oil component, a Group II base oil component, and a Group III base oil component; and a minimal amount of a particular polyalphaolefin component. The lubricating compositions provide improved film thickness and wear properties relative to conventional mineral oil lubricants. In particular, the lubricating compositions provide improved film thickness and wear properties relative to conventional mineral oil lubricants, without the need of having to include additional polar additives to enhance wear and film thickness characteristics.

摘要： A working fluid monitoring system for monitoring a working fluid of working fluid system of a piece of equipment is provided. The working fluid monitoring system can include a filter member having an inlet, an outlet, and a filter media disposed between the inlet and the outlet. The filter member can be configured to permit fluid communication of the working fluid of the working fluid system from the inlet, through the filter media, and out the outlet of the filter member. A sensor is in operable communication with the working fluid within the filter member and is configured to monitor in situ a parameter of the working fluid and/or the working fluid system.
