Abstract
A method for detecting and responding to fugitive fueling of an internal combustion engine uses monitoring of the variability of at least one fuel-linked engine operating parameter to determine that fugitive fueling is occurring. Once fugitive fueling is detected, mitigation will be implemented so as to shut the engine down without consequential damage.
Claims17
A system for detecting and responding to fugitive fueling of an internal combustion engine, comprising:
- a controller for monitoring the variability of a fuel-linked engine operating parameter, with said controller comprising:
- at least one device for measuring the value of said fuel-linked operating parameter;
- a processor for calculating the variability of the measured operating parameter;
- a comparator for comparing the calculated variability of the measured operating parameter with a maximum permissible value for said variability, with said controller setting a fugitive fueling flag if the result of such comparison indicates that fugitive fueling is present;
- and
- at least one engine shut down device, connected with said controller, and activated in response to said fugitive fueling flag, for stopping the engine notwithstanding the presence of fugitive fueling.

A method for detecting and responding to fugitive fueling of an internal combustion engine, comprising:
- monitoring the variability of a fuel-linked engine operating parameter;
- comparing the monitored variability of said operating parameter with a maximum permissible value for the variability of said operating parameter;
- and
- if the monitored variability exceeds said maximum permissible value, taking steps to mitigate improper engine operation resulting from fugitive fueling.
