NOVELTY - The system has a sensor (118) provides an engine signature to a computer (106). A simulator module utilizes a computer processor to generate simulated signature features associated with a simulated vehicle having prescribed defects. A self-learning module utilizes the processor to learn associations between simulated signature features and prescribed defects. The computer processor compares engine signature with associations of self-learning module to produce a probability indicator that engine has the prescribed defect at a specified intensity associated with a diagnosis of engine.    USE - System for analyzing engine of vehicle. Can also be used in indicating when driver license is about to expire, tire tread depth, pressure, and blowout risk, brake pad thickness, battery failure based on temperature extremes and deep cycle re-charges, fuel run out time/location based on engine, load, terrain, head wind and road/traffic conditions, road-side service risk on proposed trip, crash risk times based on accident history, sun-in-eye and driver, hours of service (HOS) optimization.    ADVANTAGE - The wear, deterioration and defects which cause variation in the pulse and vibration patterns are eliminated. The signatures are periodically captured over the life of the engine to monitor loss of physical integrity. The historical information about the operating conditions of the vehicle is tracked. Since the mean time to failure of critical components in engine is predicted, the fleet manager is allowed to prioritize actions to mitigate the risks. The problematic cylinders are identified by the engine signatures. The global administrator information, user information, vehicle information, operations information and remote data information are updated continuously.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for analyzing the engine of the vehicle.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the engine analysis and data collection system.
