Abstract
A fuel quality monitoring system includes a fuel composition sensor configured to provide an indication of a composition of a liquid fuel within a fuel tank, and a controller. The controller is configured to receive the indication of the monitored fuel composition from the fuel composition sensor; detect an amount of an impurity from the received indication; and compare the amount of the impurity to a threshold. If the amount of the impurity exceeds the threshold, the controller is configured to adjust an operating parameter of an engine to account for the detected impurity. When the amount of the impurity exceeds a threshold which makes engine combustion unmanageable, the fuel is restricted from entering the engine or fuel tank.
Claims19
A fuel quality monitoring system comprising:
- a fuel composition sensor configured to provide an indication of a composition of a liquid fuel within a fuel tank;
- a controller configured to:
- receive the indication of the monitored fuel composition from the fuel composition sensor;
- detect an amount of an impurity from the received indication;
- compare the amount of the impurity to a first threshold;
- and
- adjust an operating parameter of an engine if the amount of the impurity exceeds the first threshold.
A fuel quality monitoring system comprising:
- a fuel composition sensor configured to provide an indication of a composition of a liquid fuel flowing through a filler tube in communication with a fuel tank;
- a controller configured to:
- receive the indication of the monitored fuel composition from the fuel composition sensor;
- detect an amount of an impurity from the received indication;
- compare the amount of the impurity to a first threshold;
- and
- restrict fuel from entering the fuel tank if the amount of the impurity exceeds the first threshold.
A method comprising:
- monitoring a composition of a liquid fuel disposed within a fuel tank;
- detecting an amount of an impurity from the monitored composition;
- comparing the amount of the impurity to a first threshold;
- and
- adjusting an operating parameter of an engine if the amount of the impurity exceeds the first threshold.
