System and method for enhanced engine monitoring and protection

A system for monitoring and controlling an engine, the system comprising:

• an engine fluid pressure sensor for measuring an engine fluid pressure;
• an engine operating parameter sensor for measuring an engine operating parameter;
• and
• a controller in communication with the engine fluid pressure sensor and the engine operating parameter sensor, the microprocessor including control logic for comparing the engine fluid pressure to an associated first engine pressure threshold, comparing the engine fluid pressure to an associated second engine pressure threshold, and generating an engine warning signal when the engine fluid pressure crosses the first threshold but before the engine fluid pressure crosses the second threshold.

A computer readable storage medium having information stored thereon representing instructions executable by an engine controller in communication with at least one pressure sensor for detecting an engine malfunction, the computer readable storage medium comprising:

• instructions for determining at least one fluid pressure;
• instructions for determining a current value for an engine operating parameter;
• instructions for determining a first pressure threshold value corresponding to the current value of the engine operating parameter;
• instructions for determining a second pressure threshold value based on the first threshold;
• instructions for comparing the at least one fluid pressure to the first and second thresholds to determine when the fluid pressure crosses the first and second thresholds;
• instructions for generating an engine warning signal indicative of the fluid pressure crossing the first pressure threshold;
• and
• instructions for generating an engine shut-down signal indicative of the fluid pressure crossing the second pressure threshold.
