Systems and processes are provided for measuring carbon deposits on an engine. In some examples, a light source can be transmitted through a viewing window of an engine onto an area of an internal surface of the engine and reflected back through the viewing window and detected using an optical sensor. A topography of the area can be determined based, at least in part, on the reflected light source detected by the optical sensor and used to determine whether carbon deposits have increased, decreased, or remained constant on the area.

Non-contact process for engine deposit layer measurement

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.

Data collection from auxiliary controller area network devices

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.

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.

Periodically heating a soot containing engine lubricant to a temperature in the range of about 115&#xb0; C. to about 150&#xb0; C. is effective in controlling soot induced viscosity increase of the lubricant. The period at which heating is conducted may be a function of the number of hours the engine has been operated or it may be based on the oil condition.

A device and method to extend the useful lubricant life in a diesel engine equipped with an Exhaust Gas Recirculation (EGR) system consisting of placing a chemical filter in an area of relatively higher humidity either in the EGR stream or near the intake manifold. In some cases, placing chemical filters in both locations would be preferred. This device may also be used in combination with a chemical filter placed in the lubricant recirculation system which produces a synergistic effect beyond the individual effects of either component.
