A system and method for analyzing and providing exception-based reports for machine data. The machine data is relayed to a remote system for automated analysis based on tests and parameters defined by an owner. If any exceptions are detected in the data based on the operator-defined input, output is generated. The output may take the form of exception-based printed or electronic reports, or the exception information may be relayed to a hand held device, preferably maintained by service personnel at the work site.

System and method for analyzing and reporting machine operating parameters

The present invention provides a method and apparatus to automatically control the speed of a work machinebased on ton-miles-per-hour limit of at least one of a plurality of tires. A vehicle information systemhaving a processorand a databasemonitors an actual ton-miles-per-hour calculation of the plurality of tires. The vehicle information systemfunctions in combination with an electronic control moduleof the machineto trigger an automatic speed reduction should the actual ton-miles-per-hour rating exceed a predetermined limit. The speed reduction may be affected by at least one of reducing a throttle setting, changing a transmission gear and automatic application of the machine brakes.

Method and apparatus for controlling ground speed of a work machine based on tire condition

An apparatus and method for reducing white smoke during start up of a compression ignition engine is disclosed. The apparatus includes an engine cylinder, a fuel injector, an engine speed sensor, and a microprocessor. The microprocessor preferably includes an engine speed controller that governs the engine speed to a desired value. The microprocessor issues a first fueling level corresponding to a difference between an actual engine speed and the desired engine speed signal. The microprocessor quits fueling the engine cylinder then determines a second fueling level. A determination about whether the cylinder is firing is then based on a comparison between the first and the second fueling level.
