Abstract: A web based method and system to determine the ambient conditions and/or surrounding or affecting a remote object during its travel, such as a vehicle, animal or individual. The system and method include pulling data from the world wide web to determine the travel path of the vehicle. Data from a nearby weather station is used to ascertain the ambient conditions along the travel path. Historical weather data indicative of historical ambient conditions in a geographical location may be stored in memory and used as predictor for travel conditions to be expected and used as a basis for the operation of the vehicle. When weather data is received that is outside of the historical weather data by some predetermined statistically significant amount, the actual data is used to alter the operation of the vehicle during travel.

Abstract: One embodiment of the invention includes a method of operating an internal combustion engine system comprising an engine, an oxidation catalyst, and a particulate filter, the method comprising: determining if the outlet temperature of exhaust gas from the oxidation catalyst is below a first temperature, measuring the time that the outlet temperature of exhaust gas from the oxidation catalyst is below the first temperature, determining if the measured time has exceeded a first time period, and if so, elevating the temperature of the exhaust gas exiting the oxidation catalyst.

Abstract: A method of operating an internal combustion engine with a variable geometry turbocharger whereby the turbocharger is cleaned of accumulated soot on a time based periodic basis.

Abstract: A method to estimate ambient air temperature in the vicinity of a vehicle equipped with an internal combustion engine equipped with at least an electronic control unit (ECU) with memory and a temperature sensor.

Abstract: A method for verifying the functionality of the components for a diesel particulate filter system based upon engine speed, engine torque, inlet and outlet exhaust pressure at the diesel particulate filter. Various sensor signals are compared to calibratable values in memory for a determination whether the diesel particulate filter system is functional.

Abstract: In one aspect, the present invention is directed to a method for operating an electronically controlled internal combustion engine in a vehicle to perform at least one rationality check on at least one sensor to detect impending sensor failure and verify component functionality. The engine is equipped with an engine control system (ECS) having a memory and in electronic communication with various sensors. The sensors transmit data signals to the ECS indicative of associated engine and vehicle component functionality.

Abstract: A method of controlling an internal combustion engine when the engine is operating in an engine braking mode is provided. The engine operates in the engine braking mode and an exhaust valve for the cylinder is prematurely opened to dissipate power. The method includes controlling airflow to at least one cylinder based on a comparison of a desired mass airflow rate and an actual mass airflow rate such that the actual mass airflow rate tracks the desired mass airflow rate.
