Abstract
A system for an engine of a vehicle, comprising of a cylinder located in the engine, a delivery system configured to deliver fuel and a fluid to at least an engine cylinder while the vehicle is traveling, said fluid comprising alcohol and/or water, and a control system for varying an amount of said fuel and fluid delivered to the cylinder in different ratios as a condition varies, said controller further varying a spark timing of a spark in said cylinder as an amount of alcohol and/or water in said fluid varies.

A method for a vehicle traveling on the road, comprising:
- receiving a fuel mixture, said mixture having at least some alcohol;
- separating said fuel mixture into at least a first and second mixture on board the vehicle, where said first mixture has a higher alcohol concentration than said second mixture;
- varying an operating parameter of the separation to vary the fuel separation in response to a vehicle operating condition;
- and
- delivering a first amount of said first mixture and a second amount of said second mixture to the engine in different ratios.
A method for a vehicle traveling on the road, comprising:
- receiving a fuel mixture, said mixture having at least some alcohol;
- separating said fuel mixture into at least a first and second mixture on board the vehicle, where said first mixture has a higher alcohol concentration than said second mixture;
- varying an operating parameter of the separation in response to a vehicle operating condition;
- and
- delivering a first amount of said first mixture and a second amount of said second mixture to the engine in different ratios under different engine load conditions, where said first mixture is delivered to a direct injector of a cylinder and the second mixture is delivered to a port injector of the cylinder, and where at least one of said first and second amounts is adjusted in response to said separation.
A system for a vehicle traveling on the road, the system comprising:
- a tank configured to receive a fuel mixture, said mixture having at least some alcohol;
- a separator coupled to said tank configured to separate said fuel mixture into at least a first and second mixture on board the vehicle, where said first mixture has a higher alcohol concentration than said second mixture;
- a control system configured to vary an operating parameter of the separator in response to a vehicle operating condition;
- and
- a delivery system configured to deliver a first amount of said first mixture and a second amount of said second mixture to the engine in different ratios.
