Abstract
The present invention provides apparatus for varying an engine's combustion spark timing for use of hybrid fuels, such as bio-fuel and gasoline. An operator selectable switch enables or disables an on-board computer selecting between gasoline and bio-fuel mixtures as the on-board fuel so that engine mounted sensors provide data used to determine optimum fuel-ignition spark discharge values from a computerized table.
Claims9
Timing apparatus for controlling ignition spark discharge in combustion engines using a bio-diesel gasoline fuel mixtures comprising:
- (a) a plurality of sensors for generating data from an internal combustion engine having an engine control unit;
- (b) a timing apparatus integrated into the combustion engine for selectively modifying the discharge of the ignition spark when the combustion engine is operating on a fuel mixture containing bio-diesel and gasoline, said timing apparatus in communication with said plurality of sensors and a computer;
- (c) a switch for activating and deactivating the timing apparatuses;
- and
- (d) the computer in communication with a data storage device, the data storage device having retrievable timing modification values stored thereon, the timing modification values enabling the combustion engine to operate on a fuel mixture containing bio-diesel and gasoline when the timing apparatus is activated.
2 more elements
A method of operating a combustion engine on a fuel mixture, the method comprising:
- providing a combustion engine with an engine control unit and an ignition spark discharge apparatus;
- providing a timing apparatus in communication with the ignition discharge apparatus, the timing apparatus having at least one sensor for receiving data from said internal combustion engine, the timing apparatus having a computer and a data storage device, the data storage device having retrievable timing modification values stored thereon, a switch for activating and deactivating the timing apparatus;
- providing a fuel mixture containing bio-diesel and gasoline;
- activating said timing apparatus;
- and
- running said combustion engine on said fuel mixture where the timing apparatus controls the ignition spark discharge apparatus.
