Engine analysis and diagnostic system
First Claim
1. A system for analyzing an engine of a vehicle having an intake manifold, a crankcase and an exhaust, comprising:
- a computer including a computer processor;
a plurality of removably attachable sensors including at least two of an exhaust sensor configured to be connected to the exhaust, an intake sensor configured to be connected to the intake manifold, and a crankcase sensor configured to be connected to the crankcase, the plurality of removably attachable sensors being configured to provide an engine signature to the computer;
a simulator module configured to utilize the computer processor to generate simulated signature features associated with a simulated vehicle having prescribed defects at a specified intensity for at least two of an intake stroke, a compression stroke, a power stroke and an exhaust stroke; and
a self-learning module configured to utilize the computer processor to learn associations between the simulated signature features of the simulated vehicle and prescribed defects for each cylinder of the engine of the vehicle,wherein the computer processor is configured to compare the engine signature for each cylinder of the engine with the associations of the self-learning module toproduce a probability indicator that the engine has the prescribed defect at the specified intensity, anddisplay a diagnosis of the engine including a plot of a nominally expected prognosis relative to a current condition prognosis to provide a projected failure time or mileage for the engine according to the at least two of the exhaust sensor, intake sensor, and crankcase sensor.

Abstract
A system for analyzing an engine of a vehicle may comprise a computer including a computer processor, a sensor connected to a portion of the vehicle and being configured to provide an engine signature to the computer, a simulator module configured to utilize the computer processor to generate simulated signature features associated with a simulated vehicle having prescribed defects, and a self-learning module configured to utilize the computer processor to learn associations between the simulated signature and prescribed defects. The computer processor may be configured to compare the engine signature with the associations of the self-learning module to produce a probability indicator that the engine has the prescribed defect at a specified intensity associated with a diagnosis of the engine.
