Abstract
A fuel delivery system for an internal combustion engine including a fuel tank, a membrane dividing the fuel tank into at least a first and second portion, the membrane preferentially diffusing a substance from a mixture, the substance having an increased knock suppression relative to the mixture, and a controller adjusting delivery of condensed water to the tank responsive to an operating condition.
Claims21
A fuel delivery system for an internal combustion engine comprising:
- a fuel tank;
- a membrane dividing the fuel tank into at least a first and second portion, the membrane preferentially diffusing a substance from a mixture, the substance having an increased knock suppression relative to the mixture;
- and
- a controller adjusting delivery of condensed water to the tank responsive to an operating condition.
A fuel delivery system for an internal combustion engine comprising:
- a fuel tank;
- a membrane dividing the fuel tank into a first portion enclosing a blended fuel mixture and a second portion, the blended fuel mixture including gasoline and ethanol;
- a first injector configured to receive fuel from the first portion of the fuel tank;
- a second injector configured to receive fuel from the second portion of the fuel tank;
- and
- a controller configured to adjust the amount of condensed water in the second portion of the fuel tank in response to an operating condition.
A fuel delivery system in an internal combustion engine of a vehicle, comprising:
- a fuel tank;
- a battery;
- a flexible membrane dividing the fuel tank into at least a first and second portion;
- a port injector coupled to the first portion;
- a direct injector coupled to the second portion;
- a water condensate system coupled to the second portion, the water condensate system including an electrically driven actuator configured to adjust delivery of water condensate to the second portion of the fuel tank;
- and
- a controller configured to adjust the actuator in response to an engine temperature and concentration of water in the second portion of the fuel tank.
